The Trigger Editor is a design tool for creating and managing a Trigger Graph by combining multiple Triggers and Trigger Operators.

LAUNCH

Trigger Editor GUI

The Trigger Editor is situated inside the Behavior Editor under the main workspace, it is composed of a workspace to design a Trigger Graph, and the Trigger Library.

Trigger Editor workspace

The workspace is a node-based graphical interface where you can combine Triggers and Trigger Operators to create a Trigger Graph.

• For controls see Trigger Editor Controls.

Several workspace tabs can be opened, each one showing the content of a Trigger Container. Without any Trigger Container opened the workspace stays empty, prompting the user to open a Trigger. Opened Trigger Containers tabs are saved with the scene.

Trigger Library

The Trigger Library is the toolbox of the Trigger Editor. It contains three views.

Triggers view

It provides a quick access to built-in triggers. Triggers can be added to the Trigger Editor workspace by drag-and-drop.

	Random	enables to start or stop a behavior randomly depending on percentage at each call.
	Current Frame	enables to start or stop a behavior by returning true if the current frame is successfully compared to a reference value.
	Polygon Zone	enables to start or stop a behavior by returning true when the position of the root bone of an Entity is contained in a polygon zone (the polygon zone being represented by a Maya polygon) or a group of polygons.
	Painted Zone	enables to start or stop a behavior by returning true when the position of the root bone of an Entity is contained in a painted zone of a specified color.
	Texture	enables to start or stop a behavior by returning true when the position of the root bone of an Entity is contained in a zone of a specified color of a Maya 2d or 3d Texture.
	Distance	enables to start or stop a behavior by returning true when the distance between the root bone of an Entity and an object (camera, mesh…) or a group of objects, is successfully compared to a reference value.
	Driven Attribute	enables to start or stop a behavior by returning true if any Maya object attribute is successfully compared to a reference value.
	Expression	enables to start or stop a behavior by returning true if the evaluation of an Expression or a Channel is successfully compared to a reference value.
	Behavior Time	enables to stop a behavior by returning true when a behavior has been running for a certain amount of time.
	Motion Time	enables to stop a behavior by returning true when a motion behavior (Motion Behavior , Locomotion Behavior, Synchronized Motion Behavior) has been running for a certain amount of time.
	Script Command	enables to start or stop a behavior by returning true when the MEL or Python command returns a value different than 0.
	Physics Collision	enables to start or stop a behavior when a collision with another physicalized entity or a Crowd Rigid Body occurs.
	Boolean	always return the same value (true or false).
	Fade	delay the perfom of  Triggers attached to a Behavior thanks to the Ramp.

Trigger Operators view

This view provides an access to Trigger Operators. As the Trigger View, Trigger Operators can be added to the workspace by drag-and-drop.

	And	perform a AND logical operator between previous connected Triggers results.
	Or	perform an OR logical operator between previous connected Triggers results.
	Xor	perform an XOR logical operator between previous connected Triggers results.
	Not	return the negation of the result of the previous Trigger.
	Accu	returns true only when the previous connected Trigger returns true a defined number of times.

Custom Triggers view

The Custom Triggers view is a file browser, pointing on a chosen directory containing Custom Triggers, i.e Trigger previously saved.

• Drag-and-drop a Custom Trigger into the workspace to load it.
• For Custom Trigger Containers, Double-click to open it in a new tab.

Notice that the browsed directory can be changed in the Crowd Settings Dialog.
