Entity Lifecycle – Arma Reforger

Definitions

• Frame: every drawing frame (frame as in FPS)
• Fixed Frame: a fixed event happening 30 times per second
• Physics Simulation Frame: a fixed event at 60 simulations per second (frequency defined in Workbench → Options → Game Project → Modules → Physics Settings → Ticks)

Lifecycle

⚠

Note that some event methods are called only when:

• such events were enabled through IEntity.SetEventMask()
• some conditions are met (EOnPhysicsActive requires the entity to have valid and activated physics, etc)

			EOnFixedPostFrame		If EOnFixedFrame executed this frame
Destruction				OnDelete
			Destructor		Do NOT delete components in an entity's destructor - this could lead to nullpointer exceptions
				Destructor	Do NOT reference the parent entity in a component's destructor - the entity is already deleted by then
