Title: Assign EventDelegate and Parameters from script
Post by: zeus_82 on September 09, 2014, 11:45:53 AM

Hey guys,

I want to assign an EventDelegate to a UIButton in addition to parameters,
I know I can do this :
button.GetComponent<UIButton>().onClick.Add(new EventDelegate(targetGameObject, "MethodToCall"));

But, how can I add parameters ?
So, If the MethodToCall has 2 parameters, I can pass them.
Please, help.

After lots of hunting this worked for me. It passed a reference to the UIButton script itself as the parameter.

        UIButton theBtnScript = theBtn.GetComponent<UIButton>();
        EventDelegate del = new EventDelegate();
        del.target = this;
        del.methodName = "NGUI3ButtonClickHandler";
        EventDelegate.Parameter theParameter = new EventDelegate.Parameter(theBtnScript, "ITEM_VALUE");
        del.parameters.SetValue(theParameter, 0);
        EventDelegate.Set(theBtnScript.onClick, del);

Thank you both for the great help.

It worked.

EventDelegate eventDelegate = new EventDelegate(this, "TestMethod");
eventDelegate.parameters[0].value = 20;
button.GetComponent<UIButton>().onClick.Add( eventDelegate );

Although the argument would be null in the inspector, but the value is serialized and coupled
with the parameter.

Sorry to necro this, but this is completely valid to the problems I'm running into.

I'm doing something similar:
My OnClickMe method gets hit, but my int num is 0. I tried other values, like string and GameObject, and they're null.

1.         UIButton b = buttonXfrm.gameObject.GetComponent(typeof(UIButton)) as UIButton;
2.  
3.         EventDelegate del = new EventDelegate(this, "OnClickMe");
4.         del.parameters[0].value = 123;
5.         EventDelegate.Set(b.onClick, del);
6.  
7.  
8.         private void OnClickMe(int num)
9.         {
10.  
11.         }

Any ideas?

Works just fine when I tried.

1. New scene.
2. ALT+SHIFT+S, ALT+SHIFT+C, attached UIButton script to it.
3. Attached this script to it:

1. using UnityEngine;
2.  
3. public class Test : MonoBehaviour
4. {
5.         void Start ()
6.         {
7.                 UIButton btn = GetComponent<UIButton>();
8.                 EventDelegate del = new EventDelegate(this, "OnClickMe");
9.                 del.parameters[0].value = 123;
10.                 EventDelegate.Set(btn.onClick, del);
11.         }
12.  
13.         private void OnClickMe (int num)
14.         {
15.                 Debug.Log(num);
16.         }
17. }
18.  

4. Hit Play, see "123" printed.

Yup, that worked for me too. Thanks for checking this out for me.

Now to figure out my EBKAC.

EDIT:
And my error was, I was doing all that in a script that wasn't an NGUI control.
