πŸͺ€ Trigger

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

πŸ’‚Authority
This class can only be spawned on 🟦 Server.
πŸ‘ͺInheritance
This class inherits from Base Actor .

πŸŽ’ 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)
Package.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)
Package.Log("Something entered my Box Trigger")
end)

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

πŸ—οΈ Constructor​

local my_trigger = Trigger(location, rotation, extent, trigger_type?, is_visible?, color?, overlap_only_classes?)
TypeNameDefaultDescription
Vector location
Rotator rotation
Vector extentSize of the Trigger. If using Sphere, only the X is used
TriggerTypetrigger_typeTriggerType.Sphere
boolean is_visiblefalseUseful for debugging
Color colorColor.REDColor to paint the Trigger bounds - if Visible
table of string overlap_only_classes{}Filter Trigger to only overlap specific Classes. Leave it empty for all Classes

πŸ—Ώ Static Functions​

Inherited Actor Static Functions
Base Actorscripting-reference/classes/base-classes/actor
ReturnsNameDescription
table of Base Actor GetAllReturns a table containing all Actors of the class this is called on
Base Actor GetByIndexReturns a specific Actor of this class at an index
number GetCountReturns how many Actors of this class exist
iterator GetPairsReturns an iterator with all Actors of this class to be used with pairs()
This entity doesn't have own static functions.

🦠 Functions​

Inherited Actor Functions
Base Actorscripting-reference/classes/base-classes/actor
ReturnsNameDescription
AddImpulseApplies a force in world world to this Actor
AttachToAttaches this Actor to any other Actor, optionally at a specific bone
DestroyDestroys this Actor
DetachDetaches this Actor from AttachedTo Actor
SetCollisionSets this Actor's collision type
SetDimensionSets this Actor's Dimension
SetForceAdds a permanent force to this Actor, set to Vector(0, 0, 0) to cancel

SetValueSets a value in this Actor
TranslateToSmoothly moves this actor to a location over a certain time
RotateToSmoothly rotates this actor to an angle over a certain time
boolean IsBeingDestroyedReturns true if this Actor is being destroyed
boolean IsVisibleReturns true if this Actor is visible
boolean IsGravityEnabledReturns true if gravity is enabled on this Actor

UnsubscribeUnsubscribes all callbacks from this Event in this Actor within this Package, or only the callback passed
ReturnsNameDescription
ForceOverlapCheckingForces a Overlap checking to occur, will immediately trigger overlaps
SetExtentSets the extent size of this trigger (sphere triggers will use only the .X component for radius)
