Triggers Main Concept

Triggers are built-in and atomic action events which can be combined together with Trigger Operators *to create more advanced action events (this combination is called *Trigger Graph).

The Trigger Graph can be executed by a Behavior to control their start and stop conditions. They are used to make Entities react to various events, such as an entity entering in a predefined zone, or being at a given distance of something else.

When an Behavior is created, two Trigger Containers are automatically created and attached to it: a Starting Trigger and a Stopping Trigger. Those Trigger Containers will be used to store a Trigger Graph. Here what does a Trigger Graph looks like by default in a Starting Trigger:

Other Triggers can be added and linked in a Trigger Graph:

Modify the root Trigger will update the Trigger Graph to execute each Triggers and Trigger Operators prior to this root Trigger:
