Hi, Kirupians!

I’m working on a top-view game in which you control a tank that fires from a rotating turret (similar to the _Wii Play_ game _Tanks_). I’ve got the movement and rotation of the turret down, and I’m using this code for the turret rotation:

```auto

_root.onEnterFrame = function(){
    turretRadians = Math.atan2(_ymouse - player._y, _xmouse - player._x);
    turretDegrees = Math.round((turretRadians*180/Math.PI));
    player.player_turret._rotation = turretDegrees;
}

```

That part works just fine, but I’m still having trouble with getting the bullets to fire in the direction I want where I click. I’ve seen [this](http://www.myflashresource.com/flash-tutorials/the-tank-part-2-rotating-and-shooting-the-cannon) tutorial, but I’d prefer to not just rotate a movie clip, as I may program in ricocheting bullets.

Should I be using trigonometry, algebra, or what? Any help would be very appreciated!

[EDIT] By the way, I’m using Flash 8.
