yeah that is what I was thinking too, and I started to write an
if/then for the code to grab it if it gets up to 179/-179 and then
switch it but it doesnt work. It seems kind of inefficient however,
there has to be another way.. I know that when I use .rotation =
(whatever) you can enter 540, for example, and it will rotate 1 1/2
times, so it is puzzling as heck. I will give it a go. I posted just
the method that I call when the user tries to rotate.
private function rotateImage():void
{
//get global center points of object rotati0on
pt1 = new Point(0,0);
pt1 = editingObj.localToGlobal(pt1);
trace(pt1)
pt1.x = pt1.x + (editingObj.width/2)
pt1.y = pt1.y + (editingObj.height/2);
// get angle of handle from center for radius bounds//
var dx1:Number = mouseDownPos.x- pt1.x;
var dy1:Number = mouseDownPos.y- pt1.y;
var ang1:Number = (Math.atan2(dy1, dx1)*180)/Math.PI;
// get angle of mouse from center //
var dx2:Number = Application.application.mouseX- pt1.x;
var dy2:Number = Application.application.mouseY- pt1.y;
var ang2:Number = (Math.atan2(dy2, dx2)*180)/Math.PI;
// rotate the _target and stroke the difference of the two angles
.001 is velocity//
var angle:Number = ((ang2-ang1)+ targetRotation )* .003
trace(angle);
var m:Matrix = editingObj.transform.matrix;
var boundM:Matrix = boundingBox.transform.matrix;
var thisM:Matrix = this.transform.matrix;
//send to rotator class
Rotation.rotateAroundInternalPoint(m, editingObj.width
/ 2,
editingObj.height / 2, angle);
//Rotation.rotateAroundInternalPoint(thisM, this.width
/ 2,
this.height / 2, angle);
//Rotation.rotateAroundInternalPoint(boundM,
boundingBox.width / 2,
boundingBox.height / 2, angle);
//reset transform matrix
editingObj.transform.matrix = m;
//boundingBox.transform.matrix = m;
//this.transform.matrix = m;
targetRotation = editingObj.rotation;
trace(targetRotation);
//setBoxesLocation();
renderBounding();
}
