The UI code uses OnGUI() to render, which is a function called automatically by
the Unity engine. The problem with OnGUI() is that it may be called several times every
frame, which causes a huge performance hit on mobile devices. If you are intending on
converting the game over to run on a mobile system, you may want to look at other GUI
solutions instead.
GUI.Label is a simple method for drawing text onto the screen. For this example
game, it is used for all of the UI:
void OnGUI()
{
GUI.Label(new Rect (10,10,100,50),"PLAYER 1");
GUI.Label(new Rect (10,40,100,50),"SCORE "+player_score);
GUI.Label(new Rect (10,70,200,50),"HIGH SCORE "+player_
highscore);
GUI.Label(new Rect (10,100,100,50),"LIVES "+player_lives);
}
}
