How can i subscribe to event System Click?

Hi,

If i have a canvas with a button that say "every body jump" and i want all my game objects that are subscribed to that click input to jump, how do i program it?

I did it with a script that have a public function that call "JumpDelegate", so when i click the button i call that function, so all my scripts that are subscribed to the Delegate event listen to it. But i was thinking, what if i just implement something like: using UnityEngine.EventSystem on all my scripts and then check if the UI button is clicked, after that i check what button was clicked, if it was jump, then i jump. That would be better than creating my owns delegates right?

but how?

 

Hi resetme,

I think you are looking for the AddListener Function of the button.

In order to subscribe to the button's onClick event, you just put:
button.onClick.AddListener(SomeMethodName);
(see http://docs.unity3d.com/ScriptReference/Events.UnityEvent.AddListener.html)

Does that help you?

 

But for that i will have to reference the button in all my scripts, right?

 

no, the whole point of the Event approach is that it is "loosely coupled". The button shouts without caring who is listening, the listeners listen for a shout without caring where it came from.
