using UnityEngine;

public class DoFullScreen : MonoBehaviour {
private bool isFullScreen;
// Use this for initialization
void Start () {
isFullScreen = false;
}

// Update is called once per frame
public void ChangeScreen()

Resolution[] screenResolutions = Screen.resolutions;
Screen.SetResolution(screenResolutions[screenResolutions.Length - 1].width, screenResolutions[screenResolutions.Length - 1].height,true);
Screen.fullScreen = true;
}
else
{
Screen.fullScreen = false;
