Precise Cursor Angle Compass
Author: Kahlen | Website: www.artmartyr.com/kahlen |

Here's the script for the control clip in its entirety:

onClipEvent(enterFrame){

    x = (_root._xmouse - _root.comp._x);
    y = (_root._ymouse - _root.comp._y);
    hyp = Math.sqrt(Math.pow(x,2) + Math.pow(y,2));
    cos = x / hyp;
    rad = Math.acos(cos);
    deg = Math.floor(180/(Math.PI / rad));

    if(y <0){
        deg = -deg;
    }else if((Math.floor(y) == 0) && (x <0)){
        deg = 180;
    }
}

onClipEvent(mouseDown){
    trace("x = " + x);
    trace("y = " + y);
    trace("hyp = " + hyp);
    trace("cos = " + cos);
    trace("rad = " + rad);
    trace("deg = " + deg);
}

Apply this script to your "comp" movie clip:

//This will set the rotation value of comp to match the variable clip.deg.
onClipEvent(enterFrame){
    this._rotation = _root.clip.deg;
}

That's it! Still confused? Ask your math professor about it (They'd know better than I would). Later! - Kahlen
