alright i have a slight problem, im just testing some stuff, and everytime the space key is pressed i want one bullet to come out, however righty now you can just hold down space and it keeps firing…heres the code i used :  
on (keyPress “\<Space\>”) {  
i = i+1;  
duplicateMovieClip(\_root.bullet, “bullet”+i, i);  
}  
any suggestions on how to fix this?

try throwing a stop(); after the duplicateMovieClip just for \*\*\*\*s and giggles.

same result…or another way to do it would be to add a timer between shots?

instead of using duplicateMovieClip you coulse use attachMovie. the syntax is just like that, but…

on (keyPress “\<Space\>”) {  
i = i+1;  
\_root.attachMovie(“bullet”, “bullet”+i, i);  
}

in the library, right click on bullet and choose linkage, and make the reference name bullet, and choose export in 1st frame, and for actionscript (the default boxes taht are checked).

</div>

```auto

if (Key.isDown(Key.SPACE)) {
	if (!_root.firing) {
		i ++;
		duplicateMovieClip(_root.bullet, "bullet"+i, i);
		_root.firing = true;
	}
} else {
	_root.firing = false;
}

```

do that instead. this will only fire if ‘\_root.firing’ is false. As soon as it fires, it sets this flag, and won’t fire again until \_root.firing is set back to false, which will happen when the space bar is released.

I recently fixed this exact problem in my game.

also, i++ is short for i+=1 which is short for i=i+1 😉
