Right. And in simple assignment, getter's returned value is returned as
the assignment formula's value. According to ECMA-262 (11.13.1), the
formula's value should be its lefthand expression.
var _mc:MovieClip = this.createEmptyMovieClip("my_mc", 1);
var a:Number = _mc._rotation=270;
trace([a, _mc._rotation]); // Output: 270,-90 // Good
var o:MyRotation = new MyRotation();
var b:Number = o.rotation=-90;
trace([b, o.rotation]); // Output: 270,270 // Bad
// ActionScript 2.0 class definition for Testing
class MyRotation {
var _rotation:Number = 0;
// gets the value between 0 and 360
function get rotation():Number {
trace(["get", _rotation]);
return (_rotation%360+360)%360;
}
// sets the value between -180 and 180
function set rotation(n:Number):Void {
_rotation = (n%360+540)%360-180;
trace(["set", _rotation]);
}
}
