ElevatorBank.Elevator.canStop()

int canStop( double floorZ , int travelDirection )

Parameters

floorZ The desired z location to stop at.
travelDirection The desired travel direction for a request. 1 means going up, -1 means going down, 0 means to ignore desired travel direction.

Returns

int 1 if the elevator can stop at the location, 0 otherwise.

Description

Returns true if the elevator can stop at the target z location and desired travel direction, given the elevator's current location and travel direction.

This method uses several factors to determine whether the elevator can stop at a given location, as follows:

  1. If the elevator is currently idle, it will always return true.
  2. If the elevator is not idle, then the desired travel direction must match the elevator's travel direction, and the target z must be "ahead of it" given the elevator's current travel direction. In other words, if the elevator is currently going down, then the target z must be below the elevator's current location. If the elevator is going up, the target z must be above the elevator's current location.
  3. If the elevator is currently moving, then the target z location must be far enough ahead of the elevator so that the elevator can stop at the target z (given its current speed and deceleration) without going past it.

ElevatorBank.Elevator.moveToFloor()

void moveToFloor( double floorZ )

Parameters

floorZ The desired z location to move to.

Returns

void True if the elevator can stop at the location.

Description

Tells the elevator to move to the target floor.

Since the elevator implements automatic logic for moving between floors, generally you will only use this method in the following situations.

  1. When the elevator becomes idle (the OnIdle event), you may want to send the elevator to a home location.
  2. If you want to preempt the elevator's normal behavior, because of some abnormal occurrence.
