[AS] Control MC created by attachMovie

function fire_bullet() {

>>>>>>>> }
>>>> }
}

In order to allow for the function to check the bullet_mcs created b must not increment but in order to allow for multiple bullet_mcs at a time it must. If I include the increment the function runs forever but if not no more than one bullet_mc can exist. Any ideas on how to get around this? Do I need an array?

b = 0;
function fire_bullet() {
b++
var bullet = _root.attachMovie("bullet_mc","bullet"+b+"_mc",_root.getNextHighestDepth());
bullet._x = ship_mc._x+(ship_mc._width/2);
bullet._y = ship_mc._y+(ship_mc._height/2);
bullet.onEnterFrame = function() {
this._y -= 30;
if(this._y < 0) {
this.removeMovieClip();
}
}
}

Try that.
