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 !
