OnDown event not triggering

[kag359six]

I have a collider with a tk2dUIItem attached to it. I set the GameObject to send the message to, and in the script of that GameObject I added the  method "onReset" to OnDown inside "void Start()". Why isn't the onReset method being triggered when i click on the UIItem?

Ok I figured out why it's not working. I was missing the OnEnable and OnDisable methods. Why are these necessary? I haven't seen these referenced in any C# events tutorial, or as a method inside Unity.

You should unsubscribe from all events you subscribe to to avoid memory leaks. You generally do that with c# events to avoid leaking objects.

They are referenced in the Unity docs, check out the list of Monobehaviours here.
