Custom Triggers

Triggers are the bridge between some kind of input and the execution of Actions and Events. What receives this input and decides whether the Trigger should be fired or not are a hidden component called Igniters.

(An Igniter tells the Trigger: Hey! Invoke the Actions & Events)

public class IgniterCollisionEnter : Igniter
public new static string NAME = "Example/Example";
public new static bool REQUIRES_COLLIDER = true;
void Start()

In the example above you see an example of Igniter that tells the Trigger to fire the Actions and Events as soon as the Start method is called.

Unlike Actions and Conditions, Igniters don't an Editor section to display the Inspector's UI
