Trigger

A Trigger class is a utility class to trigger events when any Entity enters an Area.


💂Authority
This class can only be spawned on 🟦 Server side.
👪Inheritance
This class shares methods and events from Base Entity, Base Actor.

Examples

local sphere_trigger = Trigger(Vector(-200, 100, 500), Rotator(), Vector(100), TriggerType.Sphere, true, Color(1, 0, 0))

sphere_trigger:Subscribe("BeginOverlap", function(trigger, actor_triggering)
Console.Log("Something entered my Sphere Trigger")
end)

local box_trigger = Trigger(Vector(300, 200, 500), Rotator(0, 45, 0), Vector(150, 150, 150), TriggerType.Box, true, Color(0, 1, 0))

box_trigger:Subscribe("BeginOverlap", function(trigger, actor_triggering)
Console.Log("Something entered my Box Trigger")
end)

box_trigger:Subscribe("EndOverlap", function(trigger, actor_triggering)
Console.Log("Something left my Box Trigger")
end)
