touching a gui texture

Questions & Answers
1

I need help trying to make it so that if the player touches the screen where there is a gui texture, Unity will recognize this, for example: if I have a scrolling list of things the player can choose from and the player selects on an option, I want it to change a variable from true to false, or if there is a pause button at the top of the screen and the player touches it, i want it to change a variable ‘pause’ from false to true

If you are talking about an actual GUI Texture GameObject,

//C# Example

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour
{
	void OnMouseDown()
	{
		print ("Clicked on " + guiTexture.name);	
	}
}

//JS Example

    #pragma strict
    
    function OnMouseDown()
    {
    	print ("Clicked on " + guiTexture.name);	
    }

If you’re talking about using GUI.DrawTexture

//C# Example

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour
{
	public Texture2D image;
	Rect rect;
	Vector2 mouse;
	
	void Awake()
	{
		rect = new Rect(0, 0, 256, 256);	
	}
	
	void Update()
	{
		mouse = new Vector2(Input.mousePosition.x, Screen.height - Input.mousePosition.y);
		if(rect.Contains(mouse) && Input.GetMouseButtonDown(0))
			print ("Clicked on image!");
	}
	
	void OnGUI()
	{
		GUI.DrawTexture(rect, image);	
	}
}

//JS Example

#pragma strict

var image : Texture2D;
private var rect : Rect;
private var mouse : Vector2;

function Awake()
{
	rect = new Rect(0, 0, 256, 256);	
}

function Update()
{
	mouse = new Vector2(Input.mousePosition.x, Screen.height - Input.mousePosition.y);
	if(rect.Contains(mouse) && Input.GetMouseButtonDown(0))
		print ("Clicked on image!");
}

function OnGUI()
{
	GUI.DrawTexture(rect, image);	
}
