Enemy shooting problem,plz help

1

hi.
i have a couple of problems:

  1. before the spawning of the enemies start i can already see there bullets firing… how do i fix it so i see them only when the enemys are visible.
  2. how do i get the bullets to come out of all the enemys, they are doplicated to enemyq0,enemyq1…

this is my code so far

general


[LEFT]

bulletCounter = 0;
_root.enemy_bullet._visible = false;
_root.enemyq._visible = false;
_global.enemy2Count = 0;
enemies2 = new Array(0);
explode2=new Array(0);
shoot2 = function ()
{
    bulletCounter++;
    _root.enemy_bullet.duplicateMovieClip("enemy_bullet" +  
                                        bulletCounter,_root.getNextHighestDepth());
    _root["enemy_bullet" + bulletCounter]._visible = true;
	
	};
enemy2 = function ()
{
    _root.enemyq.duplicateMovieClip("enemyq" + _global.enemy2Count, _root.getNextHighestDepth());
    _root["enemyq" + _global.enemy2Count]._visible = true;
    posX = random(500)+1
    posy= random(500)+1
    _root["enemyq" + _global.enemy2Count]._x = posX ;
    _root["enemyq" + _global.enemy2Count]._y = posy;
     enemies2[enemy2Count]="enemyq" + _global.enemy2Count
     explode2[enemy2Count]="false"
    _global.enemy2Count++;
};

setInterval(enemy2,4000);
setInterval(shoot2, 1000);

this is on my “enemy_bullet”:

onClipEvent (load)
{
reset=function(){
    this._x = _root.enemyq0._x;
    this._y = _root.enemyq0._y;
    bulletSpeed = 5;
    
    this._rotation = Math.atan2(_root.hero._y-this._y, _root.hero._x-
                                          this._x);

}
  reset();
	
	
}

onClipEvent (enterFrame)
{

		
    this._x = this._x + Math.cos(this._rotation) * this.bulletSpeed;
    this._y = this._y + Math.sin(this._rotation) * this.bulletSpeed;

}

any help would be grately appreciated…
