Multiple buttons in one script

[Harsul]

Hello.

I am trying to make multiple buttons on OnClick i just can't get it to work.
I need something like this:

1. void OnClick()
2. {
3.     if(buttonOne is Clicked)
4.         ....
5.        
6.         if(buttonTwo is Clicked)
7.         ....
8. }

Or it could be on void Update it doesn't really matter.
But is there anyway to do this?

You would need that one script to be attached to a single object then every button could have the UIForwardEvents script on it which could forward the click event to that one object. From there UICamera has a couple options for telling you what was clicked. lastHit will give you more detailed information about what was clicked as it returns a RayCastHit or your can look at the hoverObject which is the GameObject the mouse is over.

Alternatively, just attach one script to every button object, which examines the button press event against the calling gameobject.name property.  Below I use OnPress, but you could use any NGUI event similarly.

For example:

public class GeneralUIButtonHandler : MonoBehaviour {

    //
    //  Simply handles button events and does the appropriate actions
    //

    void OnPress(bool isDown)
    {
        // return without doing anything if this is a button up event
        if (!isDown) return;

        // don't trigger buttons if the mouse click isn't a left mouse button event
        if (UICamera.currentTouchID != -1) return;

        // do actions based upon the name of the gameobject
        if (this.gameObject.name == "Button_1")
        {
            // do something here
        }
        else if (this.gameObject.name == "Button_2")
        {
            // do something else here
        }
    }
}

Granted, you'd probably not want to use this for dozens and dozens of buttons, but for just a few it'll work just fine and the comparison evaluations shouldn't be much of a hit since it's local object data with a string compare.

Use a UIButtonMessage and send a "Button1Clicked" or "Button2Clicked" (etc) to the helper object of your choice. Have your helper object have a script (component) with  void Button1Clicked() {} and void Button2Clicked() [} defined. Release the game and make tons of $$.
