quick question simple answere (sin/tan)

ok i am mad that i cant figure this out after to long. here is what i need;

I have a mc instance named mech, and my mouse cursor instance name aim ( so the mouse shows up just as the aim thing crosair) i have it so when u click it makes a laser mc show up where ur position is, but i need to have it move towards where the cursor was at the time, the code i have for this so fari is:
on the main timeline:

Code:

---

        ground.onPress = function() {
                trace("mc clicked");
                laserCounter++;
                _root.laser.duplicateMovieClip("laser"+laserCounter,_root.getNextHighestDepth());
                _root["laser" + laserCounter]._visible=true;
               
        };

---

where ground is the mc for the entier stage , (ne way to make that so i can just click and hold?) and laser is the instance name for my laser on the screen.

next code: on the laser mc

Code:

---

onClipEvent (load) {
                        this._x=_root.mech._x;
                this._y=_root.mech._y;
                laserMoveSpeed=10
}

onClipEvent (enterFrame) {
        //i need the code here for finding the angle,
        // and using it to do move speed so the lsaer moves towards where
        //the mouse crosair thing is
}

---

please help i kno its not hard but i just need it fixed, thanks !

hmm wont let me edit but, i think the code might have to do this, but how would i use the _mouse._x, it dont work, and is atan2 the right thing t ouse?

Code:

---

// when we fire
for (i=1;i<=laserCounter;i++) {
_root["laser"+i].targetAngle = Math.atan2( aim._y - mech._y, aim._x - mech._x );
_root["laser" + i]._rotation = _root["laser"+i].targetAngle / ( Math.PI / 180 );
_root["laser" + i].moveSpeed = 2;

_root["laser" +i].onEnterFrame = function() {
        this._x += Math.cos( this.targetAngle ) * this.moveSpeed;
        this._y += Math.sin( this.targetAngle ) * this.moveSpeed;
        //check for collision and destroy enemy or die when we go off stage or after set amount of time
}

---

and i would use a for statement for the lasers, but just miainly the code i have problem with now , all i need is to change enemy to the mouse positino , how i do that,

just test it, runs to slow so i ahve to abort, hmm how can i right this so it actually will run! please help me! just stupid laser go towards the cursor aargg!
