Im making a 2D game for android.I almost completed the game but now I need a pause game option.I added a pause icon on the top right side of the screen.The icon is a gui texture.Here is what I did so far :

I made a script which will bring up some buttons (which is not working) and attached it to the GUITexture.This is the script :

#pragma strict


function OnMouseDown() {
Debug.Log("*Pause Menu Opens*");
Time.timeScale = 0;

if (GUI.Button(Rect(10,10,100,50),"Restart"));
Application.LoadLevel(Application.loadedLevel);

if (GUI.Button(Rect(10,60,100,50),"MainMenu"));
Application.LoadLevel("MainMenu");
}

Now,the problem stands at the part where the buttons won't show up,the game freezes at the first frame but the buttons won't show up.Please,if you can help I would be realy thankful.

Thank you.

Edit #1 : I just noticed that when I click "Pause" the game freezes and it takes me to the MainMenu.That's because I added the GUIButton which takes you to the main menu.I think the whole script structure is wrong.I also forgot to mention that Im new in scripting/unity.

Thank you.
