Hello everyone

If anyone can help in the following problems then thank you in advance.

I am looking to fix the code I have created, I have an array of tanks (3) and bullets (3). In the code the bullet is supposed to fire from the tanks 2 out of 200 times on “enterFrame”. The bullets are placed in same rotation and position as the tank but they will not fire, where am I going wrong?!

The code is just the bit of the tanks and how they interact with the user (spaceship).

[AS]stage.addEventListener(“enterFrame”, updateXY);

function updateXY(evt:Event){

```
for(var i:int = 0; i &lt; myArray.length; i++) {
		var dx:Number = spaceship.x - myArray*.x;
		var dy:Number = spaceship.y - myArray*.y;

		var angle:Number = Math.atan2(dy, dx);
		var deg:Number = angle * (180 / Math.PI);

		myArray*.rotation = deg;
	
}

```

}

var myArrayBulletsSpeed:Number = 16;  
var myArrayBulletsFired:Boolean = false;

var myArrayBulletsXspeed:Number;  
var myArrayBulletsYspeed:Number;

stage.addEventListener(“enterFrame”, firemyArrayBullets);

function firemyArrayBullets(evt){

```
for(var i:int = 0; i &lt; myArray.length; i++) {
	if("enterFrame" && myArrayBulletsFired == false){
	if(Math.random() * 200 &lt; 10){
	myArrayBulletsFire();
	}
	
}
}

```

}

function myArrayBulletsFire(){

```
for(var i:int = 0; i &lt; myArray.length; i++) {
	
	//for(var i:int = 0; i &lt; myArrayBullets.length; i++) {
	
	var dx:Number = spaceship.x - myArray*.x;
	var dy:Number = spaceship.y - myArray*.y;

	var angle:Number = Math.atan2(dy, dx);
	
	myArrayBulletsXspeed = Math.cos(angle) * myArrayBulletsSpeed;
	myArrayBulletsYspeed = Math.sin(angle) * myArrayBulletsSpeed;
	
	myArrayBullets.x = myArray*.x;
	myArrayBullets.y = myArray*.y;
	myArrayBullets.rotation = myArray*.rotation;
			
	myArrayBulletsFired = true;
	stage.addEventListener("enterFrame", updatemyArrayBullets);
	//}
}

```

}

function updatemyArrayBullets(evt:Event){

```
//for(var i:int = 0; i &lt; myArrayBullets.length; i++) {

myArrayBullets.x += myArrayBulletsSpeed;
myArrayBullets.y += myArrayBulletsSpeed;

if(spaceship.hitTestPoint(myArrayBullets.x, myArrayBullets.y, true)){
	trace("hituser");
}	

if(myArrayBullets.x &lt; -100 || myArrayBullets.x &gt; stage.stageWidth + 50 || myArrayBullets.y &lt; -100 || myArrayBullets.y &gt; stage.stageHeight + 50){
	myArrayBulletsFired = false;
	stage.removeEventListener("enterFrame", updatemyArrayBullets);
	//removeChild(myArrayBullets);
}
//}

```
