Passing the object as event argument

[Setzer22]

Hello everyone.
Quick question here, I want, when an envent is triggered, to be able in some way to retreive the insance of the object which triggered the event, from a class which catches that event.

So let’s say, for example that class Character triggers the event OnMove, but there are many instances of Character in the scene, so i want the class (let’s say) MovementManager, which is subscribed to Character.OnMove to know which was the character which actually moved when subscribing to that event.

Thank you very much

Ok, lazy me… Figured this out myself.

So for the class triggering the event, you should declare (I’ll use the example I posted in the original question so it’s easier to follow):

public delegate void CharacterEventHandler(GameObject e);
public static event CharacterEventHandler OnMove;

//And this when sending the event
public void SomeRandomMethod() {
    OnMove(this);
}

Then, for the class registering to the event, make sure the method you subscribe to the event is declared like this:

//this method is subscribed to the event
void WhenCharacterMoves(GameObject character) {
    //Here you can refer to the character which move with "character"
}

That’s it, too bad I didn’t look that up myself… Anyway, hope it helps someone
