I looked at the [tutorial on how to fire in a game](http://www.kirupa.com/developer/mx/fire.htm) , and tried to replace the clicking the button to hitting the Z button, so it looks like this

This is the code on pressing the key:  
[AS]onEnterFrame = function(){  
if (Key.isDown(90)){  
\_root.fire = 1;  
\_root.i += .1;  
duplicateMovieClip(\_root.bullet, “bullet”+i, i);  
}

}[/AS]

And this is the code on the bullet:  
[AS]onClipEvent (load) {  
this.\_visible = 0;  
if (\_root.fire == 1) {  
this.\_x = \_root.player.\_x;  
this.\_y = \_root.player.\_y;  
}  
}  
onClipEvent (enterFrame) {  
if (this != \_level0.bullet) {  
if (\_root.fire == 1) {  
this.\_y -= 10;  
this.\_visible = 1;  
}  
if (this.\_y\<0) {  
this.removeMovieClip();  
}  
}[/AS]  
…basically the same except replacing “crab” with “player”…

Now the problem is, when i release the key an extra bullet fires off, and then when i press Z again,that bullet dissappears in mid-air every other time, so is there a way to get that last bullet to just not fire off and be removed?
