The User Commands tool lets you add, delete, and edit custom commands in your model.
Once you have created your command you can call it like any other FlexSim command. It will appear in blue when typing code and it will appear in the Command Summary. You can also hover the mouse over the command and press F1 to display the Command Helper.
User Commands are accessed from the Toolbox.
The following are some of the valid parameters you can enter in the Parameters and Return Type fields:
The following are valid parameters, but not return types (use num for the return type):
var parameter with accept any of the datatypes. To specify multiple
datatypes but not include all datatypes you can concatenate parameters together using a
In the Parameters field you can have optional parameters by enclosing the additional parameters in square brackets at the end of the list:
(var object, num type [, int flags])
If your command specifies any of the above data types as parameters that will be passed in to the command, you can access those parameters through the param command:
Where num is the rank from the parameter list. For example, if the parameters was specified as:
(treenode dataNode, num maxNumDataPoints, num incrementValue)
You would access those values in your code by:
treenode dataNode = param(1); double maxNumDataPoints = param(2); int incrementValue = param(3);
When you open the command documentation from the menu Help > Commands, the user commands will be shown in the command documentation in addition to all of the built-in FlexScript commands. The description field shown above will be displayed as html so you can use html markup for formatting, such as <b> and <\b> for bold. Because the description allows for html markup, some standard characters do not work properly, such as <, >, &, and new line characters. To display these types of characters, you can use special markup codes, such as ">" (without the quotes) for a > symbol and <br/> for a line break. If any of the commands' descriptions container invalid html markup, FlexSim may throw an exception when you try to open the Users Manual and your commands will not be properly documented.
