Title: Prefab losing target - specifying parameter ?
Post by: DarJam on November 02, 2014, 05:53:05 PM

My prefab containing UIButton and onClick notify with target where i want the object clicked in one of many to be passed to a target. Unity removes the on click information from the prefab after the first use. This was answered on another message but that did not include a parameter. How do i code it with a parameter?

1. table[i] = (GameObject) Instantiate( Resources.Load( "Prefabs/NGUI/Table/tabledef_basic"));
2. EventDelegate.Add( table[i].GetComponent<UIButton>().onClick, FixturesPressed);    
3. EventDelegate.Parameter = table[i];
4.  
5. public void FixturesPressed(GameObject go){
6.    Debug.Log ( go.name + " clicked!");
7. }
8.  

The compiler generates

error CS1502: The best overloaded method match for `EventDelegate.Add(System.Collections.Generic.List<EventDelegate>, EventDelegate)' has some invalid arguments
Error CS1503: Argument `#2' cannot convert `method group' expression to type `EventDelegate'

It works fine without a parameter but i need a parameter. Can anyone help ? Thanks

OK, this type of question is answered on other posts.My problem was a table of game objects with variable information and size and when clicked i wanted it to pass a message to a higher object and i needed to know which one was tapped. I found this worked well.

1. ...
2. EventDelegate del = new EventDelegate(this, "FixturesPressed");
3. del.parameters[0] = new EventDelegate.Parameter(go, "gameObject");
4. table[i].GetComponent<UIButton>().onClick.Add ( del );
5. ...
6. public void FixturesPressed (GameObject go)
7. {
8. Debug.Log(go.name);
9. }
10.

Same result, much less code:

1. EventDelegate.Add(button.onClick, delegate () { Debug.Log(go.name); });
