Questions & Answers

Hi everyone, is there a function that destroys or disables a GUI? I need a way to disable or destroy GUI.Button when the boolean isAvailable is false.

bool isAvailable;     

if( isAvailable = true){
    if (GUI.Button(new Rect(100, 10, 50, 50), "SomeButton")){}
    }
    else if( isAvailable = false){
//Destroy or Disable GUI.Button
}

You were almost there and didn’t know it. You don’t have to worry about destroying a button at all, just put a condition on whether or not the button should be drawn in the first place. Remember that buttons are redrawn every time OnGUI is called.

Here is a quick example of how to stop drawing the button after it is clicked:

C#

using UnityEngine;
using System.Collections;

public class ExampleConditionalButton: MonoBehaviour 
{
	public bool isAvailable = true;
	
	void OnGUI()
	{
		// Check to see if this button
		// should be available
		if (isAvailable)
		{
			// Draw the button
			if (GUI.Button(new Rect(100, 10, 50, 50), "SomeButton"))
			{
				// Disable Button After Click
				isAvailable = false;

				// Add code for any additional
				// behavior when the button is clicked
			}
		}
	}
}

Hope that helps you out.
