add an explosion were hitTest occured

hi
i am using AS3 and i have this hitTest occuring:

Code:

---

function hittest(e:Event):void {
        for (var i=0; i<bulletArray.length; i++) {
                if (rocketShip.hitTestObject(bulletArray[i])) {
                        trace("hit");
                        removeChild(bulletArray[i ]);
                        bulletArray.splice(i,1);
                        var fire:MovieClip = new explosion();
                        addChild(fire);
                        fire.x = rocketShip.x + 20;
                        fire.y = rocketShip.y - 5;
                       
                        }

---

so at the moment an explosion called "fire" is added to the front of my ship when the hitTest = true, but sometimes my bullets don't hit the front, they might hit the side or back of my ship. so i would like my explosion to be added to wherever the hitTest occurred on the two objects.
thanks

The easiest way would be to simplify your ship to a circle, or oval, and then find the point of intersection based on the angle to the bullet.

Code:

---

var shipWidth:Number = 10; //define constants
var shipHeight:Number = 5;

var angle:Number = Math.atan2(bullet.y - ship.y, bullet.x - ship.x); //angle to the bullet (y comes first)

var explodePoint:Point = new Point();
explodePoint.x = shipWidth * Math.cos(angle);
explodePoint.y = shipHeight * Math.sin(angle);

---

Something to that effect. Assuming the math is correct :p
