A*

Updated Transporter fork lifts to move during A* offset travel.

Added support for acceleration and deceleration for A* travelers. This required a significant refactor of the logic under the hood. Things to be aware of:

We added an update script that will set to zero the acceleration and deceleration of all task executers attached to the A* navigator. This means that most statically attached task executers should work generally the same as they did before, although the refactoring extended into the collision avoidance scheme (incorrect timings were fixed), so there may be slight differences in how the objects avoid each other.
Our update script does not cover objects in the flow item bin, so if you create objects from the flow item bin that use the A* network, they will likely have nonzero acceleration and deceleration, and thus will behave differently now. Set those properties to zero, and they should behave more closely to the way they behaved in older models. The Create Person activity automatically sets these properties to zero when it attaches a person to the A* network.
A* no longer supports doing te-logic offset travel with nonzero deceleration because early task finishing causes potentially incorrect travel paths (through barriers). Either use zero deceleration, in which case they will always travel all the way to the destination point before offsetting, or make them use A* for offset travel, in which case they'll properly build the new offset path using A* barriers from the shortened destination point. See A* - Acceleration / Deceleration for more information

Fixed issue with slot labels not being remembered. If you set a slot label in FlexScript, and the script execution is not part of a simulation run (e.g. through a dashboard button, auto-build, executing script manually, etc.), then it will save that label value as its 'reset' label value, so that when you reset the model, it will stay at / go back to that value. Previously, labels that were set in script would be reset to nothing on reset.
Updated Table() constructor to correctly handle GlobalTable nodes. Previously, passing a GlobalTable node into the constructor would not correctly use its data variable as the table node and would instead use the Object node itself.
Removed Separator renaming split items.

AGV

Added user-customizable deadlock recovery. Added parameters to the OnAllocationFailed trigger that lets the user know if the allocation request represents a deadlock, as well as an array that is the deadlock cycle. The user can thus implement logic if the allocation failure is a deadlock, and return 1 to tell the system that the deadlock has been handled.

Added an OnNavigationFailed trigger that is fired when the AGV can't resolve a valid path to a destination. This is to give the user the ability to handle the error. Returning 1 means try again, returning 2 means end the task.
Added parameters to the Custom Path Cost: a forward/backward boolean and a reference to the AGV if there is one.

Added AGV.traversalPoints property and AGV.TraversalPoint class.
Made AGV.AllocationPoint.stopDist writable.

Added several triggers to A* objects:

AStar.Navigator: OnGridChange: called when dynamic barriers are added or removed
AStar.Traveler: OnCalculatePath: called just before a traveler's path is being calculated
AStar.Traveler: OnNavigatePath: Called just before a traveler runs the algorithm to define kinematics and cell allocations for traveling its path. Also allows the ability to override the default behavior and define your own.

Improved the deadlock recovery algorithm. Now it will add each traveler in the deadlock, as well as any travelers that are waiting on those travelers, as dynamic barriers. Then it will go through each traveler in the deadlock, remove it from the dynamic barriers, add any additional travelers that are adjacent to that traveler as barriers, then try to recalculate the path to the traveler's destination. If it finds a traveler that can still travel all the way to its destination, that traveler will be rerouted. Otherwise, if it finds a traveler that can travel at least on grid square, it will reroute that traveler. Otherwise, it will give a notification of unrecoverable deadlock.

AStar

Added a Strict Diagonals setting to make travelers travel better around corners.
Fixed dynamically added members not allocating an initial cell.

Conveyor

Added a Mass Flow Conveyor.
Fixed items sometimes becoming detached from their accumulation chain after the conveyor backs up.

Removed Conveyor Types.
Removed Decision Point Types, Photo Eye Types, Station Types, Entry Transfer Types, and Exit Transfer Types. In doing this, we moved type triggers like OnArrival, OnContinue, OnBlock, OnClear, etc. directly to their owning object instances. This required a shift in parameter references. For example, a Decision Point Type OnArrival trigger's param(1) becomes ownerobject(c) on the object instance's trigger, param(2) becomes param(1), etc. We have implemented update scripts that translate the code properly for all pick list options and for all code headers. However, we have erred on the side of caution in translating param() references that are inside a user-defined code body. Thus if you have manually written code in one of these triggers, and this manually defined code includes param(), parval(), or parnode(), you will need to update that code manually on the object instance.

Fixed a draw issue with tables drawing bold text sometimes.
Fixed a bug with window docking.

Changed updatehotlinks() to only repaint the views if it applies a node with a viewsyncupdate attribute of 1.
The keywords VALUES and DELETE were added to the sql parser. This means that previous models that use the term VALUES, Values, values, DELETE, etc. will get an error because sql now sees it as a special keyword.

Changed behavior for when a TaskExecuter is connected to an AGV network, and is set to use the navigator for its offset travel.

Changed the times when AGVs will go into the blocked state. Now they will become blocked as soon as they cannot allocate ahead. And they will become blocked as soon as the are proximity-interrupted on an accumulating path, instead of waiting until they are fully stopped.
Several changes have been made to the AGV accumulation behavior, specifically in calculating when an AGV accumulation stop event should happen. This should not drastically change AGV behavior. However, minor timing differences may appear in existing models.

Changed point source light attenuation.
Changed TASKTYPE_NODEFUNCTION to pass variants in as parameters instead of interpreted legacy doubles.
This fixes the types of arguments that are passed when calling treenode.evaluate() as part of a TASKTYPE_NODEFUNCTION task. This allows you to add TASKTYPE_NODEFUNCTION tasks with parameters that are not just numbers, (nodes, strings, arrays, etc.) and have those parameters be preserved in a type-safe manner and properly passed into the subsequent treenode.evaluate() call. However, this change may have some consequences for older models.
The following guidelines apply:
1. If you use the inserttask() command, and cast a node to a number with tonum() to pass it in as a task variable, then you should use parnode() to get those parameters out in the nodefunction. While this method will continue to work, this mechanism is nevertheless deprecated.
2. The now-correct method for adding a TASKTYPE_NODEFUNCTION task to a task sequence is to use TaskSequence.addTask(). This method takes full Variants as its task variable parameters, so you do not need to use tonum(). When using this, you should use param() to get the parameters back out.
Older models that use neither of these methods may need to be updated to use method 2 in order to work properly in this version.

FlexSim 17.2.1 (August 31, 2017)

Included fixes listed in 17.1.6 below.

FlexSim 17.2.0 (August 31, 2017)

Reorganized the User Manual and updated its formatting.
Added more topics, tutorials, and reference pages to the User Manual.
Added new Statistics Collector and Calculated Table tools.
Added new generic charts for plotting statistics gathered with Statistics Collectors and Calculated Tables.
Updated the pin to dashboard buttons to create and use Statistics Collectors instead of the legacy charts.

Added options for following objects with the view.
Improved MTBF/MTTR state listening to use less events and be more precise.
Updated the Network Navigator to work for an object that is inside a container that is connected to the network.

Fixed a bug with global variable highlighting and autocomplete.
Fixed an issue with destroying a TE on a network when it blocks space on the network.
Included fixes listed in 17.1.5 below.

Fixed a bug with min() and max() when using distribution functions.
Previously, getting the number of columns in a Global Table using Table.numCols or gettablecols() returned 0 when the number of rows was 0. Column headers and data types are preserved even when there is no row data. These commands now return the number of columns.
Changed operators to not change their incline rotation when traveling on inclines. This will change location calculations if you have advanced logic based on internal operator locations.
NodeListArrays like Object.outObjects can no longer be implicitly cast to an Array. Use the toArray() method instead.
Fixed a bug with animations drawing their first frame instead of their last frame at times beyond the endtime.
Added a special rule for ambient color {0, 0, 0} to not use the ambient color. This change will make shapes with ambient {0,0,0} to appear brighter. Change the ambient color to a dark gray, such as {1,1,1} if you want them to remain dark.
Fixed a bug in the shader that dulled specular highlights with the diffuse texture. This may change how shapes look; they may appear shinier now.
Added the IS NULL and IS NOT NULL clauses to SQL. Math and comparison operators on null values now return NULL. FlexSim's SQL execution engine is now more in line with the SQL ANSI standard regarding null values. Specifically, if you do comparisons or math operations on elements that have null values, this will return null values. This is different than in FlexScript, where a null value acts like 0 in math operations. Also, null values will be ignored in aggregation functions like AVG().
An option to use legacy SQL nulls was added to Model Settings to preserve backwards compatibility. Upgraded models will automatically enable this option, but new models will default to using the SQL ANSI standard for nulls.
Added support for more SQL query operators, such as the case-when-then-else-end operator and window functions. This adds many new keywords to SQL, meaning that if you used these as column names in older queries, they will create syntax errors in the query parser in this version. To fix this, put square brackets [] around the column name.
Changed accessing dynamic label properties to use evaluate() instead of value. For example, consider the following code sample:
    Variant value = current.MyLabel;
In 17.1 and previous, this code was the same as:
    Variant value = current.labels["MyLabel"].value;
In 17.2 we changed it so that this code is now the same as:
    Variant value = current.labels["MyLabel"].evaluate();
The difference is in how FlexScript-toggled node values are retrieved. In 17.1 and previous, current.MyLabel would have just given the text that is the FlexScript code. In 17.2, retrieving current.MyLabel will actually evaluate the FlexScript as code. This is consistent with how table values are accessed. If you have old code that explicitly tried to get the code text with current.MyLabel, you will need to update that code in 17.2 to use current.labels["MyLabel"].value.

Added functionality for pasting images into Process Flow views.

Added a bridge element to the A* network.
Added functionality for collision avoidance.
Improved heat maps for analyzing A* traffic.

Changed the path finding algorithm for the A* navigator. When you tell an A* traveler to travel to an object, now it will behave more like the default navigator. It will calculate a "threshold radius" around the object, based on the object's size. Then it will only travel to the edge of that radius. This makes it work better especially for loading/unloading to/from rack objects. The travel operation won't commit as much to traveling to the center of the object, because that can be left to the load/unload operation, which determines exactly where in the rack to pick/place the item. However, this change does affect how older models work because it changes the routes that travelers take.

Added a Make Array label aggregation type to the Batch.
Added Center in View buttons for fields with pointer data.
Added a name property to the Token FlexScript class.

Fixed a bug with duplicating Process Flows using the Toolbox.

Updated the Pull From List activity so it does not assign a null label when nothing was pulled or the token was released early (manually). Previously, if you used a Max Wait Timer or Max Idle Timer (or some other mechanism) to release a token from a Pull from List prematurely, the label specified in the Assign To field would be created with a value of NULL. Now, the label will not be created. This may break other models that are checking to see if the label value exists. For example, saying objectexists(token.pulled) will throw an exception if the pulled label is never created. This can be easily remedied by changing the code to objectexists(token.pulled?). The ? will cause the value returned to be nullvar when the pulled label does not exist.
Universal Edit fields are now more strict when accessing labels on a token. Previously, typing token.labelThatDoesNotExist would happily return NULL and move on. Now the Universal Edit will throw an exception if the label doesn't exist. This does not include Universal Edit fields that assert labels, for example the Assign To fields.

The new version of Flexnet Publisher requires network license servers to be upgraded. They need to use the latest vendor daemon and update the Flexnet Licensing Service. More information can be found in the license upgrade instructions at https://www.flexsim.com/ftp/LicenseServer/
Updated the Separator's order of events (executing OnEntry before Setup Time) to be consistent with the Processor.
Users of the mesh api should update usage of GL_QUADS to use GL_TRIANGLES instead. GL_QUADS is deprecated and will not work when using the OpenGL Core Profile.
Since the new FlexScript parser compiles to machine code, the order in which parameters are evaluated has changed to be aligned with the x86/x64 calling convention. This means models containing code where parameter evaluation order is important may have changed results. For example, the following code will have different results:

myusercommand(duniform(1, 5), duniform(1, 10))

In the x86/x64 calling convention, parameters are evaluated from last to first. In this case, the duniform(1, 10) call will be called first. Since this call changes the state of random stream 0, changing the order of parameter evaluation changes the result.
The new parser has a stricter grammar for the == and != comparison operators. The types of the operands must be the same or related. For example, the following code will now give compile errors because it is comparing unrelated types:

double x = 0;
treenode y = model();
if (x == y) { }
This version introduces a new Array type, which is an array of variants, enabling a more feature rich array usage. In doing this, we are deprecating the old array types of doublearray, intarray, stringarray, and treenodearray. Specifically, the old array types are now just aliases for the standard Array type. This means that you can now, technically, put a string into a doublearray and vice versa, because they are all just Arrays. Hence we encourage you to just use Array in your code instead of the old array types.

This change has also introduced a problem regarding the Variant type. In previous versions, the Variant could hold each of the four types of arrays, and it had a type value associated with each type, which you could get with the getvartype() command, comparing that value to one of VAR_TYPE_INTARRAY, VAR_TYPE_DOUBLEARRAY, VAR_TYPE_STRINGARRAY, or VAR_TYPE_TREENODEARRAY. Now, however, since we've merged all of those types into one, all of those values would theoretically be the same value, introducing issues if you had code that switches on getvartype(), or in some cases if you had a series of if/else compares on that value. Depending on the specific nature of that code, it would be hard to predict exactly how that code would behave going forward. Thus, we have decided to get rid of those old macros for each array type. Now there is just the macro VAR_TYPE_ARRAY.

If you have existing code that uses the older macros, you will get compile errors when you open your model in version 17.0. We do this specifically so that you will be notified of code that needs to be updated. There are also several pick list options in the process flow module that use these older macros. Version 17 includes update scripts that will hopefully update all of those pick options in existing models to use the new VAR_TYPE_ARRAY macro instead of the old macros.
With the new FlexScript parser, there are now some differences with how the parser compares a null variant to 0. In the old parser, the following expressions applied:

(nullvar == 0) is false
(nullvar <= 0) is true
(nullvar >= 0) is true

In the new parser, the following expressions apply:

(nullvar == 0) is false
(nullvar <= 0) is false
(nullvar >= 0) is false

This brings the <= and >= operators inline with the == operator. However, old code will evaluate differently now. The following expressions apply in both the new and old parsers:

(nullvar < 1) is true
(nullvar > -1) is true
The param() command will now return nullvar if the parameter number is greater than the number of parameters passed to the function (previously it returned 0).

Fixed Fluid Conveyor throwing exceptions on reset.

Updated to OpenGL 3.1. Deprecated OpenGL functions, such as glBegin(), glEnd(), glVertex(), glNormal(), and glTexCoord(), may no longer work correctly on some graphics cards. You should instead use the mesh api.
Changed the way that fixed resources (except the Combiner) receive items when they are being transported in. Previously, when they were notified that an item was being transported in, they would close their inputs and create an event to receive the next item. This would cause problems if the upstream objects had multiple items to send because their routing strategy would work differently when transporting vs not transporting. We have fixed this so that routing strategies will work the same when transporting as when not transporting. This may change the way that old models work because it changes the events that are created, and, obviously, it fixes routing strategy logic.
menumain(), menubelow() and getviewmenu() have changed. Instead of returning a double, they now return a var. Any calls to these commands will need to be updated to use var or the value returned will be 0.
double myMenu = getviewmenu();
Changes to:
var myMenu = getviewmenu();
Previously the Fluid Conveyor would stop conveying if no material was moved into it (ie inputs were closed). This was changed so that the Fluid Conveyor continues to convey the material in it whether any additional material is added or not. Set the conveyor speed to 0 in order to keep the same functionality that was in previous versions.

Conveyor

Added Ports to the Entry and Exit Transfers.
Added a Restart Delay setting to Conveyor Types.

Fixed the Join Conveyors Tool when connecting conveyors with a custom conveyor type.

Process Flow

Added Preemption activities (Save Token Context, Release Token and Restore Token Context).
Added gettokens() and getbatch() commands.
Added Templates for Fixed Resource and Task Executer Process Flows.

Added a Speed Type and Repeat Type to the Run Animation activity.
A lot of improvements to the Zone.
Updated the evaluation of the Return Value from the Finish activity so that executesubflow() can get a return value from multiple Finish activities.
Added Activity Profiles to the token trace histories.

Fixed a bug causing the Wait for Event to evaluate its Max Wait Timer even if the token left the activity.
Fixed issues with the releasetoken(), createtoken(), and releasebatch() commands working differently when running vs stepping.

Changed the way that a token manually released (preempted) from waiting in a task sequence activity manages the task that it's waiting on. Now the task will be removed, and the task executer preempted if currently working on it. This may change older models that release tokens in task sequence activities.

AGV

Added Event info to AGVs and Control Points for use with event listening objects (Wait for Event and Event-Triggered Source in Process Flow).
Added AGV templates to Process Flow.

Fixed bug with way points not firing their OnArrival for redirected AGVs.

Restored the Media Files window (Main Menu > View > Media Files).
Added the ability to assign unique random streams to objects in the model using the command getstream().
Added a Network Navigator Properties window. (Right-click a NetworkNode to access.)
Added a Track Number Field Totals option to the List for stats collection.
Added a 'Values Only' data distinction option to the Excel Importer. This data distinction reads number data and string data from excel cells without regard to the cell's formatting (i.e. dates and times are imported as Excel time values).
Implemented the excelrangeread() command to import a range of cells using the 'Values Only' data distinction.
Added the command convert() for converting model/Excel dates and times.
You can now use keyboard shortcuts for debugging. Next Line -> F10, Step Into -> F11, Continue -> F5, Stop Simulation Clock -> Shift+F5
Updated object statistics to use Tracked Variables for collecting Content, Input, Output, and Staytime statistics. NOTE: These new statistics are only available for new objects. See the Object Statistics backwards compatibility note below for more information.
Made the sql IN clause work if you compare it against a value that is an array.
Added trackedvariable() and inittrackedvariable() commands. This allows tracked variables to be created on objects as labels, etc.
Tracked Variables can now be accessed using the commands get(), set(), inc(), setnodenum(), getnodenum(), getlabel(), setlabel().
Tracked Variables now have a Type which can be Level, Cumulative, Time Series, or Categorical (see inittrackedvariable() documentation).
Tracked Variables can now store profiles (similar to state profiles, the profile stores data on the amount of time the tracked variable was at each given value).
Improved OpenGL compatibility with older graphics cards and Nvidia Optimus cards.

Fixed a bug in the Separator state management that was causing it to be idle when it should be blocked.
Changed the max bones per mesh for bone-animated shapes from 60 to 42.
Object Statistics: We have changed the default statistics structure for objects in the library. This will not change the structure of existing models, but will now be different for new objects that are created. Specifically, we have made the standard object statistics--namely input, output, content, staytime, and state--use tracked variables instead of the many different object attributes they used previously. This enables us to add new capabilities, such as a content-vs-time graph that exactly reflects the object content changes instead of an interval-based time graph (use the Tracked Variable vs Time chart or the pin button in the Quick Properties Statistics panel), and the ability for Process Flow Wait For Event activites to listen to object content, input, output changes, etc.

Current FlexSim features will work for both the old and new statistics structures. If you have model or module code that is accessing statistical data directly (such as using commands like get(stats_contentavg(object)) or get(rank(state_profile(object), STATE_IDLE))), this code will continue to work on objects that have the older structure, but it will not work for new objects added to the model. If you want this access to work with objects having the new structure, you should use the getstat() command to get the desired data. The getstat() command will work on both the old structure and the new structure. Below is a list of examples of old statistical access commands vs new getstat() based access.

OLD: get(stats_contentavg(object))
NEW: getstat(object, "Content", STAT_AVERAGE)
(Note here that the getstat() command will return the weighted average that includes the time that the object has been at its current content, whereas with the old method, you had to add that on manually).

OLD: get(stats_staytimemax(object))
NEW: getstat(object, "Staytime", STAT_MAX)

OLD: get(rank(state_profile(object), STATE_IDLE))
NEW: getstat(object, "State", STAT_TIME_AT_VALUE, 0, STATE_IDLE)
(Note here that the getstat() command will actually give you the total time in the idle state. This includes the time in its current state if the object is currently idle. With the old method you always had to manually add that in, i.e. get(rank(...)) + (getstatenum(object) == STATE_IDLE ? time() - get(state_since(object)) : 0);

OLD: getstatenum(object)
NEW: getstatenum(object)
The getstatenum() command works on both structures, so you don't need to change it. Alternatively, you can use getstat(object, "State", STAT_CURRENT, 0) (0 is the state profile)

OLD: getinput(object)
NEW: getinput(object)
The getinput() and getoutput() commands work on both structures, so you don't need to change them. Alternatively, you can use getstat(object, "Input", STAT_CURRENT)

Conveyor

Added Pull and Send To functionality to conveyors. This is done by connecting multiple objects to a single entry/exit transfer.
Added reset position functionality to conveyors.
Added additional events to conveyor objects that can be used in connection with the Wait for Event and Event-Triggered Source activites in Process Flow.
You can now explicitly remove connections from an entry/exit transfer without it being deleted (using the right-click menu). This is useful when sending flowitems to a list where connections are not required.
Straight and curved conveyors now have an optional Virtual Length.
Added Priority and Preempt fields to the Exit Transfer.
Added a Station object. The Station works much like a Decision Point but also allows you to specify a processing time and optionally call operators.
Added States to conveyor objects.
Added a CONV_INFO_GET_ACTIVE_ITEM option to the conveyorinfo() command to get a decision point or photo eye's covering item.

Fixed decision points and photo eyes not saving to user libraries when adding a conveyor.
Fixed conveyor widths not updating when changing conveyor types.
Fixed issues not being able to snap decision points to the beginning or end of conveyors.
Fixed the conveyor type so new conveyors use the default conveyor type rather than Custom.

Fixed the Release Area pick option in decision points.
Various other bug fixes and improvements to conveyors.

Process Flow

Added a label filter option for tokens in Quick Properties.
Process Flow View now supports a 3D mouse.
Updated activity snapping to allow activities to be snapped to the top of other activities.
Updated the Release Resource activity to allow a reference to a Resource Shared Asset to be passed into the Resources to Release property.
Blocks of activities and display objects can now be saved in User Libraries.
Added aligning functionality to the Process Flow view.
Added snap-to-grid functionality to the Process Flow view.
Speed improvements to drawing.
Assign To properties on the Create Object, Push To List, Pull From List and Create Task Sequence can now either overwrite the assigned label's data or insert the data at the front (creating an array).
When tying the Resource shared asset to a Group, Dispatcher or Array, the Count property now allows you to utilize any number of those objects. This allows you or the experimenter to easily change the number of available resources without objects being added/removed from the model.
Added a 'Do not remove entries from List' option to the Pull From List activity allowing you to utilize the Request and Require fields without removing entries.
Tracked Variables can now be added as labels on objects. This allows you to track the history of its values as well as tie it to a Wait for Event activity as a value change listener.

Fixed issues with the Finish/Sink activity not properly deallocating shared assets if they still had children in the model.
Additional bug fixes and overall improvements.
Fixed exceptions sometimes being thrown when dragging connectors around.
Fixed the Priority field in the Create Task Sequence activity.
Fixed some issues with listening to the OnStateChange of objects.
Fixed an issue that caused large numbers of TE/FR instances to take a long time to reset.
Fixed an issue with the Resource when using a Local type with each instance having a unique resource reference.

The Assign Labels activity used to allow you to pass in a treenodearray or a Group so that it assigned labels to multiple objects at once. Now the Assign Labels only accepts one treenode at a time. Passing in a treenodearray will cause only the first entry in the array to have labels assigned to it. To update any old model utilizing this functionality, loop through each object in the array using the Object from Label Array pick option.

AGV

Updates to AGV travel tasks and preempting.
Some minor bug fixes.

AGVs will now read the end speed of the travel task and use it to determine when to finish the task. This means that if you have an existing model where you defined a non-zero end speed of a travel task, older versions would have ignored this, but now the end speed will be simulated properly. Please see the user manual topic on AGV Types for more information on how the end speed is simulated.
We changed the AGV preemption mechanism so that:
1. When you preempt an AGV, if you do not immediately give it a new travel task, it will decelerate to stop after the preemption occurs. In previous versions the preemption mechanism stopped the AGV immediately.
2. If you preempt an AGV and then immediately give it a new travel task, it will start the new task at the speed it was at before it was preempted. In older versions, a preemption would cause the AGV to immediately stop and then start from speed 0.

Changed Copy to also put the path to the highlighted object onto the clipboard and removed Copy Path to Clipboard from the tree's right-click menu.

Improvements to the Excel Importer's Automatic Data Distinction option. It now correctly determines if a cell has a number in it but is stored as text. In this case, instead of importing a numeric value of 0, it will import the text as a string.
Fixed Time Plots in the dashboard so they clear their data after the warmup time is complete.

Fix for Task Executers so the endspeed works for offset travel.
Fixed fly paths to run in real seconds when not running with the simulation time.

Fixed resource item state variables are now stored with a custom data structure instead of being stored directly in the tree. This means that if you previously accessed an item's fixed resource state directly through the tree instead of using the commands getitemstate(), getitemsendto(), getitemvar(), etc. your model will need to be updated to use those commands.
Previously, drawfont() would only change the font for one call of drawtext(). Now, calling drawfont() will change the font and leave it that way until it is changed again.
Fixed the 50-flowitem receive limit on the combiner, processor, and rack. This will break old models if your model is dependent on this bug.
Null Variants no longer equate with 0 (NULL). We have added the "nullvar" keyword that equates with null Variants. This could affect models that use getlabel() on a label that does not exist. For more information, see getlabel()'s documentation.
The following commands now take/return Variants instead of doubles:
- nodefunction()
- sendmessage()
- function_s()
- function_n()
- userfunction_s()
- userfunction_n()
- nodefunctionlisten()
- delayednodefunction()
- addbundleentry()
- applicationcommand()
The implications for these changes are as follows:

nodefunction(x, tonum(current)); // BAD CODE
nodefunction(x, current); // GOOD CODE

The problem here is that if you cast it into a number, and on the other side someone wants a node, the Variant thinks it's a number so it won't give back a valid node.
Additionally, all FlexScript and c++ code nodes now return a Variant instead of a double. This also has implications.

return tonum(centerobject(current, 1)); // BAD CODE
return centerobject(current, 1); // GOOD CODE

Here again, if you put something into a number, and then on the other side it wants a node, the variant realizes it's holding a number and won't give back a valid node.
We have implemented an update script that will search the model for this type of code and will update the code to not use tonum(). The update script logs any changes made, putting the log in the node MODEL:/Tools/CodeUpdateLog.

The update script will make the following changes:
1. return tonum(...);
  changes to:
  return (...);
2. For each of the above mentioned commands, the update will search the model for calls to this command, and will update the parameters as follows:
  nodefunction(theNode, tonum(...), tonum(...));
  changes to:
  nodefunction(theNode, (...), (...));
However, the update script will NOT catch the following:

double myVal = tonum(...);
return myVal;

or,
double myVal = tonum(...);
nodefunction(theNode, myVal);

In saying this, please realize that leaving number casts in these areas may continue to work properly, particularly if you the user control both sides of the pass-off, i.e. you have implemented both the caller side and the callee side. For example:

Caller side:
nodefunction(theNode, tonum(theObj));
Callee side:
treenode myVal = parnode(1);

This example should actually work properly. We have deprecated parnode(), parstr(), and parval() and replaced them with a single param() command that returns a type-safe Variant. However, the deprecated commands will essentially try their best to take whatever was passed in and put it into whatever you want. So parnode() will see a number, and try to get it into a treenode. This is the same for returns:

Callee side:
return tonum(myObj);
Caller side:
treenode myObj = tonode(nodefunction(theNode, ...));

Again, this should work, because tonode() and tonum() will essentially try to take whatever is there and put it into a number/node.
Where this will break is where one side is using the type-safe method while the other is not.

Caller side:
nodefunction(theNode, tonum(theObj));
Callee side:
treenode myVal = param(1); // WILL NOT WORK BECAUSE param(1) IS A NUMBER NOT A NODE

On FlexSim's side we have moved all (or most) of our code over to using the type-safe method. Thus any calls that interact between FlexSim code and your code should use the type-safe method. We hope that the proactive update script will resolve this for 99.99% of cases.

Update the Excel Import/Export to handle importing into bundles and export bundle data.

Expressions can now be used in select columns of an sql query. In order to do this we needed to change our sql grammar to be more compliant with standard SQL. This means you can no longer use the AS clause in a WHERE or ORDER BY statement. You can now only use AS in SELECT and FROM clauses.
Some parameter types for the query command have changed in c++ for more flexible type definitions. This means if you use the query() command in a c++ dll, you'll need to update your dll's headers and recompile the dll. If you use straight c++ compiled code or FlexScript for your query() command, then this should just update.
Removed expertfit. Use Stat::Fit.

Excel Multi Table Import using Automatic Data Distinction will import empty cells as string data, rather than as the number 0.

AGV

Fixed a bug with cpaddlistener() where the control point wasn't passing the right values into the listener callback.
Fixed a bug with custom control point allocations not being cleared on reset.
Fixed a bug where an agv will "jump" if turning around at a path section that doesn't fit its full length.
Fixed a floating point precision issue where the agv doesn't always deallocate a control area on arrival at the next control point and thus causes deadlock with himself when he needs to reallocate the area after turning around for the next task.

Created a Quick Properties docked window that is context sensitive. The window will display the most used properties based on the current selection or the active document window.
Tree Find/Replace is now integrated with the Quick Properties window and has support for case-insensitive searches as well as searching for node names.
Library Icon Grid enhancements to include filtering, collapsible groups and edit modes.
Library Icon Grid is context sensitive and changes its display based on the current selection or the active document window.
Added a sampler button that is placed throughout the software to allow users to sample images, 3D media, objects, nodes, numbers, strings and colors. The sampler helps to eliminate some need for writing code.
Downloads page that gives functionality to download and install Modules, 3D Shapes, Images and Models.
Added a Measure/Convert tool
Improved script console allowing scripts to be saved both in individual models and to the user environment. You can also now debug your script console code.
Improved Presentation Builder interface.
Improved the Flowitem Bin interface including making packing modes for container flow items visible and editable. Flowitem shapes may be changed through a drag and drop from the Library Icon Grid.
Flowitems can now have their own custom animations.
Improved the employment of shape frames in FR objects and Flowitems.
Added a No Select flag to all objects.
Added a multi-table Excel export and overhauled the Excel interface to match the MTEI. The new MTEI includes an option to automatically reimport tables on reset.
Improved Animation Creator, including dynamic animations using animation variables, more detailed editing of keyframes, and keyframe triggers. 3D shapes may be added to an animation through a drag and drop from the Library Icon Grid.
Created a global model start date/time that is tied to TimeTables. A stop date/time may also be specified.
Revamped TimeTable window. A daily or weekly schedule may now be imported through the MTEI.
Added and updated several picklist popups removing all text based picklist options.
Improvement in the Code Editor and other areas where logic is defined through draggable constructs in the library icon grid and sampler buttons throughout popups and picklist widgets to automatically add code, etc. FlexSim commands also display a short description when typing in the code editor.
Picklist fields and many popup fields have code highlighting and autocomplete.
Added some FlexScript implementations of lambda expressions.
Better debugger that allows you to access the tree and other areas of FlexSim while in debug mode. Hovering over variables during debug mode will display their current value.
Panel control GUI enhancements.
Added dashboard constructs that will replace most need for the GUI builder: Users can now do model input through dashboards instead of having to use the GUI builder. Multiple dashboards may be created.
You can now pick which navigator a TE is connected to through their properties page (allows you remove them from all navigators).
New hot keys/accelerators. Ctrl+K and Ctrl+L to resize objects up or down by 5%. Ctrl+W to close the active document window or the active floating window. Updated Ctrl+Tab and Ctrl+Shift+Tab to moved between tabs in the active floating or document window.
Added the FluidConveyor to the default fluid library.
Can now view an object's events by right clicking an object in the 3D view and selecting View | View Object Events.
Complete OptQuest overhaul (includes multi-core support and experimenter integration).
Better support for importing 3D shapes. FlexSim now supports the following formats:
*.wrl; *.3ds; *.dxf; *.stl; *.skp; *.dae; *.obj; *.ac; *.x; *.ase; *.ply; *.ms3d; *.cob;*.md5mesh; *.irr; *.irrmesh; *.ter; *.lxo; *.csm; *.scn; *.q3o; *.q3s; *.raw; *.off; *.mdl; *.hmp; *.scn; *.xgl; *.zgl; *.lvo; *.lvs; *.blend
Added a new mesh class for drawing in OpenGL.
Stereoscopic 3D rendering (requires workstation Quadro or FireGL card for frame-sequential rendering).
Enhanced graphical compatibility with integrated Intel cards.
Improved 3D rendering, including shadow rendering, specular highlights on 3ds objects, bump maps, parallax maps, etc.
Module Development SDK, including:
- Added SimpleDataType data type, which is a low-overhead class for fast, memory-efficient aggregation of data and for better object-oriented module code, with an easy mechanism for saving in the tree.
- Updated visual studio wizards that work with VS 2012
- A module sample tutorial.
- More Documentation.

Removed 2D Shapes from objects.
Removed the Planar view.
Many open gl commands have been deprecated. The model update mechanism tries to replace all old usages with the new graphics usages. Usually this should work, but in some cases it may not. Note that glBegin(), glEnd(), glVertex(), glNormal(), glTexCoord() have all been completely deprecated, and eventually will no longer work. Going forward you should use the mesh api.
The spaceobject() command has been deprecated and no longer works. In optimizing the graphics engine we realized that a 5-20% refresh rate improvement can be attained simply by removing functionality that is solely there to make the spaceobject() command work. So we've deprecated this command. It is still in the command list so models will update, but updated models that use it will have weirdly drawn shapes.
OnLoad is no longer dispatched by the engine when a project/tree is loaded. If you have custom objects that depend on this event, you will need to use some other mechanism to fire logic when the model loads, i.e. through the OnModelOpen, or through model libraries' OnModelOpen.
Kinematics functionality has changed so that by default kinematics will automatically be pruned off as you pass their individual end times. Note this required a restructuring of the kinematics data, so if your models don't do it on reset anyway, you'll need to re-initialize kinematics in models that are updated from older versions.
In previous versions, getdatastat() was documented incorrectly for the parameter p2 (degrees of freedom). It was actually interpreting p2 as the number of samples in the set, not degrees of freedom. We've fixed that by simply not using that parameter and inferring the number of samples/degrees of freedom from other parameters. This means if you used this command previously it will return different/better results in this version. Also we've changed the way the confidence interval "clamps" to percentages in order to be "safer". Again this affects the values that were returned in previous versions vs this version. See the command documentation on getdatastat() for more information.
We changed the name of the class FlexsimObject to FlexSimObject in-line with our naming scheme going forward. We have implemented an update script that replaces all instances of "FlexsimObject" with "FlexSimObject" in updated models. This means if certain things in your model are dependent on the name "FlexsimObject" (I don't know what that could be, except for maybe dll code that uses the name FlexsimObject) there may be issues with the update.
The assimp 3ds importer is translating some of the files (namely the robot clamps) in a way that is different than our old 3ds importer. It is possible that other 3ds files may need their offsets manually adjusted after updating.
Fixed the per-event 50-flowitem receive limit on the queue. This will break old models if your model is dependent on this bug.
Fixed a bug with deceleration on a network when the task executer is blocking space and is given two travel tasks in a row (this might change old models)
Several attributes were removed, so if you use these attributes in your model you will need to update your model properly:
- Removed Attributes: assertshape, asserttexture, billboard, distcutoff, events, instances, OnCaptured, OnCollision, OnInterrupted, state_graph, state_histo, state_percent, stats_contenthisto, stats_customgraphs, stats_throughputgraph, stats_throughputgraphmaxpoints, stats_throughputhisto, tables, textureaxis_s, textureaxis_t, travelstarttime, traveldirection, travelendtime, traveltimealpha, traveltimebeta, travelvpeak, traveldistance, travelstartx, travelstarty, travelstartz, travelendx, travelendy, travelendz, travelvmax, travelacc, traveldec
- Removed Draw Attributes: ignoredraw, ignorezbuffer, nochildrotate, nochildscale, noondraw, nopredraw, shapetype, reflective, luminous
- Removed Commands: travelto, traveltoupdate, ntravelto, ntraveltoupdate

FlexSim 6.0.2 (August 1, 2012)

Other minor bug fixes from the development list.

FlexSim 6.0.0 (March 23, 2012)

Enhanced the experimenter to use multiple cores.
Added a new web browser GUI widget.
Added a new Dashboard window with HTML5 canvas statistics graphs.
Redesigned the experimenter interface to integrate the new statistics objects.
Added new experiment variable options "number of objects in group" and "number of task executers."
Developed web accessibility: Opening, configuring, running, and viewing models over the web (using a web browser or handheld device).
Added a new AutoCAD dwg importer.
Added model units and conversion windows. When building a new model, a screen will ask you what model units you will be using. When updating an old model, a screen will ask you what model units were used to build the old model. These settings are stored in the Tools folder of the model.
Modified the picklist and trigger gui widgets to be easier to use.
Created a new node datatype (DATATYPE_BUNDLE) for storing large amount of information efficiently (see documentation of bundle commands).
Implemented a way to package media (3D shapes and bitmaps) into the model file so that you only need to distribute one file instead of a whole directory of files.
Added an embedded command documentation window that can be opened by highlighting a command and pressing F1 in the code window or tree view.
Added a FlexScript call stack to the debugger.
Added a step-in function for FlexScript user commands and nodefunctions in the debugger.
Added a logic builder interface for writing FlexScript logic without writing code. (You can change the default editor back to Code by unchecking 'File > Global Preferences > Environment > Use Logic Builder by Default'.)
Enhanced the flexibility of pull logic and added a new pullitem() command for use in the Pull Strategy trigger.
Improved templates to allow for popup gui windows on picklist options.
Added a mechanism for multiple state profiles.
Changed tables to always show the headers despite scrolling.
Fixed a bug that was messing up the save operation when out of memory.
Toggled the large-address-aware switch so that FlexSim can allocate more memory.
Added floor() and ceil() commands.
Added a switch for hashing the node's subnodes' names for quick lookup.
Added an option in the Labels tab so that labels' values can be automatically reset.
Other various fixes from the development list.

Fixed a critical bug in curved network length calculations.
Fixed issues with gettenetnode() and distancetotravel() on TEs that use "do not travel offsets and block network space."
Made a change to distancetotravel() to base the "back-to-node" distance on the center of the object instead of the object's location.
Changed pulling to no longer override the send-to. Now both send-to and pull must check out to transfer a flowitem.
Changed receiveitem() so that it doesn't behave as if it were pulling.
Made the Rack's OnEntry trigger fire before evaluating the dwell time.
Added a new random number generator to generate seeds based on the replication number for the existing random number generator. Email support if you need a script to initialize the streams of a particular model back to the values used in prior versions.
Added a new overload to the command tonode() to handle large memory addresses. Dlls will need to be recompiled with updated headers to obtain this fix.
Fixed a bug where an endspeed of 0 wasn't properly telling a task executer to continue at full speed at the end of a travel task. The behavior now correctly matches the documentation.
