AS2 or AS3? For AS2 you can disable the movieclip from being clicked by mc.enabled = false; For AS3 you can either remove the event listener like mc.removeEventListener("your event listener type used", onClickFunc) or you can add a flag (boolean variable) that you set to false when enlarged and use it for checking in your onClickFunc and decide whether to change the movieclip color or not.
I use AS 3.0.
if I remove the event listener, how can i enlarge the object in the first place??
When should the object magnify and when should it return to its original size? Within the function it magnifies, add the code to remove the listener. Then add it again in the function that returns it to its original size.
i did it
i add two times to the movie clips and it works =]
