Hi,
It looks better than my deadzone calc's which take up a lot more
code (I have 2 directions and a deadzone area in the middle and around
the outside of the "mouse area" controlling the velocity), but you are
welcome to compare below - I think mine is a bit more verbose, but I was
trying to make sure I could debug and come back to it in a few months
time and understand. Whatever works for you I guess.

private function _mouseMoveHandler(event:MouseEvent):void {
var tmpX:Number;
var tmpY:Number;
//Get x, y in relation to centre of stage - need to "clamp"
tmpX = this.mouseX - WIDTH / 2;//event.stageX -
this.stage.stageWidth / 2;
tmpY = this.mouseY - HEIGHT / 2;//event.stageY -
this.stage.stageHeight / 2;
var absX:uint = Math.abs(tmpX);
var absY:uint = Math.abs(tmpY);
var dirX:int = tmpX / absX;
var dirY:int = tmpY / absY;
//clamp the movement to a maximum;
tmpX = Math.min(_clampMax, absX) * dirX;
tmpY = Math.min(_clampMax, absY) * dirY;
//App.debug("mouse " + this.mouseX + ", " + this.mouseY + "
tmp" + tmpX + ", " + tmpY + " abs " + absX + ", " + absY);
//only respond to a minimum position from centre within our
square..
if (_clampMax <= absX || _clampMax <= absY) {
_mouseClamp = true;
return;
}
_mouseClamp = false;
if(_clampMin < absY) {
_velX = (absY * dirY) / _mouseDamping;
} else {
_velX = 0;
}
if(_clampMin < absX) {
_velY = -((absX * dirX) / _mouseDamping);
} else {
_velY = 0;
}
//App.debug("mouse Move " + _velX + ", " + _velY);

hi guys
I'm working on a carousel and i have a quick question about adding a
non-active area in the middle
at the moment, the carousel will move forward and backward based on the
mouse's position in relation to the center of the carousel but I'd like to
widen that by nDeadzoneRadius
here is the way that i'm doing it at the moment - it seems very clunky to me
but it's doing the job
this is on the onMouseMove listener
private function adjustSpeed():Void
{
var nMousePos:Number = _root._xmouse - nCenterX;
// !HACK! this is the bit i'm querying
if (Math.abs(nMousePos) < nDeadzoneRadius) nMousePos = 0;
else nMousePos = (nMousePos > 0) ? nMousePos - nDeadzoneRadius :
nMousePos + nDeadzoneRadius;
// end of !HACK!
nSpeed = nMousePos / ((36 / _nNumberOfItems) * 1000); //4:800,
8:4000, 12:3000, 24:1500
}
so i guess my question is, is there a more elegant solution to this, please?
