Script Command Trigger
The Script Command Trigger enables to start or stop a behavior by returning true when the MEL or Python command returns a value different than 0.
- Behavior Editor / Trigger Library:
- Golaem Menu: Crowd Triggers / Triggers / CrowdTri Script Node
- MEL command: glmCrowdTriScriptCmd;
|Script||The script command to execute.|
|Script Language||MEL or Python.|
The following MEL command counts and returns the number of entities in a circle of radius 2 Maya units, located at the center of the scene. The trigger will return true if this number is not 0:
spatialRequest -center 0 0 0 -radius 2 -type count;
This trigger can be useful when dealing with complex conditions or to execute a specific MEL or Python code during the simulation. The script command may contain special tags such as #pid#, #ps# or #gid# to interact with particles (see Technical Documentation ).
For example, if the user defines the function:
global proc int startBehavior(string $particleSystem, int $particleId)
To call this function with the current particle, the MEL command to use is: startBehavior("#ps#", #pid#);
