Making a selectable UI object

Greetings,

I have normally used something like this to make a sprite clickable in my current project:

Code (CSharp):

1.                     clickableThing.AddComponent<scriptR>();
2.                     clickableThing.GetComponent<scriptR>().setReference(r);
3.                     clickableThing.AddComponent<BoxCollider2D>();

*ScriptR contains a reference to thing and an onClick function.

However this won't work in the UI. I've found I need to use a button and add a onClick listener I'm having trouble getting it to work right.

If I add the following it still fails:

Code (CSharp):

1. clickableThing.AddComponent<Button>();
2. clickableThing.GetComponent<Button>().onClick.AddListener(() => {clickableThing.GetComponent<scriptR>().copyOfOnClickFunction})

What's the right way of doing this for things in the UI?

 

Something here will probably help you best

The UI does not use the OnClick methods. Instead it uses interfaces. You need to make your scriptR implement the appropriate IPointerClickHandler interface.

IPointerClickHandler was exactly what I was looking for! Thanks!
