An Event Handler can be created using the {{Link/Enfusion|armaR|ScriptInvoker}} class; it is good practice to '''not''' instanciate them by default but to rather create them on request, using their getter:
<enforce>
class TAG_Example
{
protected ref ScriptInvoker m_OnEvent; // do not create it by default as ScriptInvokers take some RAM (and might be numerous)


ScriptInvoker GetOnEvent()
== Script Invokers ==
{
if (!m_OnEvent)
m_OnEvent = new ScriptInvoker(); // create it only on request


return m_OnEvent;
* An Event Handler can be created using a '''{{Link|enfusion://ScriptEditor/scripts/Game/Helpers/SCR_ScriptInvokerHelper.c|ScriptInvoker}}''' class.
}
* Any Script Invoker signature can be created using {{hl|{{Link|Arma Reforger:Scripting: Keywords#typedef|typedef}}}} - see {{Link|Arma Reforger:ScriptInvoker Usage#Signature Declaration}}.
 
* Using the {{Link/Enfusion|armaR|ScriptInvoker}} class itself is considered bad practice and '''must''' be avoided.
void Event()
* As Script Invokers are big objects and can be numerous, it is good practice to '''not''' instanciate them by default but to rather create them on request, using their getter - saving memory.
{
if (m_OnEvent) // if it does not exist, do not create it
m_OnEvent.Invoke(); // it means that no one subscribed to it, making Invoke execution pointless
}
}

Script Invokers

  • An Event Handler can be created using a ScriptInvoker class.
  • Any Script Invoker signature can be created using typedef - see ScriptInvoker Usage - Signature Declaration.
  • Using the ScriptInvoker class itself is considered bad practice and must be avoided.
  • As Script Invokers are big objects and can be numerous, it is good practice to not instanciate them by default but to rather create them on request, using their getter - saving memory.
ⓘ
See ScriptInvoker Usage and its Signature Declaration section for tutorials on how to use Script Invokers.

TurretControllerComponent can also trigger this event

OnWeaponChanged

 BaseMuzzleComponent Both weapon and character can raise this event (see BaseWeaponManagerComponent)

OnMagazineChanged

OnProjectileShot

OnWeaponAttachmentChanged

 WeaponComponent isAttached is true if attachmentEntity was attached to the weapon, and false if it was detached

OnZeroingChanged

 currently does not carry currentMuzzle

OnGrenadeThrown

HHMMSS

 TimeAndWeatherManagerEntity Triggers based on TimeAndWeatherManagerEntity's TIME_EVENT_PERIODICITY value:
  • 0: never
  • 1: every hour
  • 2: every minute
  • 3: every second

OnNightStart


Entity Event Handlers

ⓘ

The following events are present and available in the IEntity class - read the code documentation to learn more about them and how to use them.

ⓘ
E in e.g EOnInit stands for Event (not Entity).
Event Description

EOnInit

 Event after the entity is allocated and initialised.

EOnVisible

 This event triggers when the entity is made visible (versus being invisible).

EOnFrame

 This event, as its name suggests, triggers on each simulation frame.

EOnPostFrame

 Triggers after physics update.

EOnFixedFrame
⚠
This event can be called on another thread than the main thread. This means that you must avoid any modifications on other entities during this event!

EOnFixedPostFrame

EOnAnimEvent

 Event from the animation system

EOnPhysicsActive

 Triggers on (de)activation of the RigidBody's physics.

EOnPhysicsMove

 Triggers when the physics engine moves this entity.

EOnSimulate

 Happens before physics engine iteration - called from sub-iterations.

EOnPostSimulate

 Happens after physics engine iteration. Happens once per frame.

EOnJointBreak

 Triggers when a joint attached to this entity's RigidBody is broken.

EOnTouch

 Event when touched by another entity. It requires the entity to have TouchComponent.

EOnContact

 Triggers when contact with another RigidBody has been registered.

EOnDiag

 Happens every frame after EOnFrame when "Entity Diag" is enabled in the Diag Menu (e.g Workbench).

EOnUser0

EOnUser1

EOnUser2

EOnUser3

EOnUser4
