52. {
53. windowsrect = GUI.Window(0,windowsrect , WindowsFunc, "Pause Menu" ) ;
54. }
55. else
56. {
57.  
58. }
59. }
60. private function WindowsFunc (id : int    )
61.   {
62.  
63.   if ( GUILayout.Button("Resume", GUILayout.Width(180) , GUILayout.Height(50)))
64.   {
65.   Time.timeScale = 1 ;
66. Paused = false ;
67.   }
68.  
69.   if ( GUILayout.Button ("Main Menu", GUILayout.Width(180) , GUILayout.Height(50)))
70.   {
71.  
72.   Application.LoadLevel ("MainMenuScene" ) ;
73.   }
74.   }
75.  
76.  
77.  

and
main menu

when i press by mouse ( resume ) or ( main menu )
it is working well
but when i press it by touch
it is not responding at all
so what should i need to edit to it
to make it able on touch on android ?

if(Input.touchCount >=1)
{
// Do something
}
