Question Button On Click from Script

Hello. I would like to add OnClick() listener to my Button component in my GameObject.

As you can see from image, I am trying to add method which takes parametr to AddListener().

The reason why I have to make it trough the script is, bcs my object is Instantiated and On Click method is from another object in the Canvas.

This Init() method is called at the Start(), but when the game starts, nothing is added in the On Click(). When I click on that Button i get huge error:

ArgumentException: method arguments are incompatible
System.Delegate.CreateDelegate (System.Type type, System.Object firstArgument, System.Reflection.MethodInfo method, System.Boolean throwOnBindFailure, System.Boolean allowClosed) (at <695d1cc93cca45069c528c15c9fdd749>:0)



Thank you

 

I've always just added a delegate like the example code shows you in the

Button.onClick

documentation.

 

It didnt work for me :/

But I solve that problem anyway.

Code (CSharp):

1.  Button btn = GetComponent<Button>();
2. UnityEvent clickEvent = btn.onClick;
3. UnityAction clickAction = new UnityAction(Show);
4. UnityEventTools.AddPersistentListener(clickEvent, clickAction);

EDIT : Now it works even with just btn.onClick.AddListener(Show), but it wont appear in the Inspector.

 

It won't appear on Inspector because the value is set at runtime (when you play the game)
