How to script a full screen button?

I was wondering how to script(prefably in javascript) a full screen button, so if you click f the game will become full screen. If you could tell me how do that, that would be great!

I have also noticed a problem with trying to go full screen. I have the following code in the Update function:

` if(Input.GetButtonUp("Fullscreen Toggle")) { Screen.fullScreen = !Screen.fullScreen; Debug,Log("Fullscreen: " + Screen.fullScreen); } `

I get the Debug.Log message with every press of the key, but the message always returns false.

It’s a little late but for anyone else that is interested the reason it returns false is that you set it false with:

Screen.fullScreen = !Screen.fullScreen;  

To enter fullscreen:

Screen.fullScreen = true;

Solution Example:

if (Input.GetButtonUp("Fullscreen Toggle")) { 
	if (!Screen.fullScreen) {
		Screen.fullScreen = true;
	} else {
		Screen.fullScreen = !Screen.fullScreen;
	}
	Debug.Log("Fullscreen: " + Screen.fullScreen); 
}

Or just do that:

using UnityEngine;
using System.Collections;

public class screenFull : MonoBehaviour {

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {

}
void OnGUI()
{
    if (GUILayout.Button("FullScreen"))
        Screen.fullScreen = !Screen.fullScreen;
}

}
