Gui Buttons Single and Double click

Question

Hey guys im new to unity and programming, and am having difficulty making a gui button that will respond to single and double clicks with different functions for each type. Example: In an rts game when u single click on a units UI button it selects that unit, when u double click that UI button it moves the camera to the players position. If anyone can lead me to how to go about doing this it would b greatly appreciated!

save a time stamp for the last click and then check the current click to see if it is less than a short amount of time. e.g.

var lastClick : float = 0;

if(GUI.Button(Rect(someRect),"double click button")){
  if(Time.time-lastClick<0.3){
     // do something
  }else{
     // do something else
  }
  lastClick = Time.time;
  print(lastClick);
}

The code worked great spinal, however there is a problem, i have more than one button and if i click on one then the other it will call the second clicks gui.button script. This will b a problem for this game ><, also I am not aware of how many buttons there will b that need to use this feature so i tryed makin seperate lastclick variables which worked but with the number of buttons that will b used unknown i cant use that method, keep in mind i am completely new to programming so im still learnin how to do things efficently. Thanks for your time and help!

Just store more variables. You can store them in a variable array if you don't know how many buttons there are at run time.

But this means that if you double click you get a single + double click. Is there a way to just get either the double or single click?

Do just what spinal Jack said but also save a reference to the rectangle used as the Rect() in drawButton. Then on the second click check the time and also check to see if the saved rect contains the mouseposition. If it does then it's a double click, if it's not then it's a different button click.
