Flashing button example

/* Flashing button example */

function OnGUI () {
 if (Time.time % 2 < 1) {
  if (GUI.Button (Rect (10,10,200,20), "Meet the flashing button")) {
   print ("You clicked me!");
  }
 }
}

Here, GUI.Button() only gets called every other second, so the button will appear and disappear. Naturally, the user can only click it when the button is visible.

As you can see, you can use any desired logic to control when GUI Controls are displayed and functional. Now we will explore the details of each Control's declaration.
