Thinker virtual functions

• void PostBeginPlay()

Called after BeginPlay and before the first call to Tick. This is done before the very first state of an actor is ever reached, useful for performing one-time setups like giving local variables a value, without worrying about a monster being dormant at the start and going to Deactivate instead of Spawn.

• void Tick()

Called every tic, 35 times a second. As the name implies, this is what makes an entity 'tick', or operate on its own.

• void OnLoad() (New from 4.14.2)

Called every time the thinker is loaded from a save game (serialized).
