When I add a new sprite by pressing down a key, sometimes I get 1 (by pressing the key really fast and lightly) but mostly 2 sprites (regular pressing) added to the screen. Is there a way to add only 1 sprite after the key has been pressed down once?

I've tried looking at the document for key in Pygame but could not get any idea how to do this.

Maybe it has to do with how when you hold a key down, it repeats the key. Try checking for event.type == KEYUP instead of KEYDOWN, since you only lift up a key once, regardless if you held it down or not. 

Will try that, thanks!
