我将获得相对于DisplayObject的锚点
例如:
// HOW GET THIS VALUES IN CODE
Object height = 90px
Object width = 40px
anchor point X = 20px
anchor point Y = 72px
//
real anchor point X = anchor point X/Object width = 0.5
real anchor point y = anchor point Y/Object height = 0.8
提前谢谢

您可以通过getBounds()
或getRect()
调用派生对象的锚点。为此,您的DisplayObject应该具有访问阶段的权限,否则getBounds()
和getRect()
将返回伪造值(已测试)。实际上,锚点对应于对象在其自己的坐标空间中的(0,0)点,因此,为您的测试对象运行test.getRect(test)
将返回(-20,-18,40,90) - 请注意Y坐标向下,而不是向上。然后,你得到那个矩形的左上角,反转它,瞧,对象的锚点相对于它的尺寸。
function getAnchorPoint(o:DisplayObject):Point {
var onStage:Boolean;
var p:DisplayObject=o.parent;
onStage=(o.stage!=null);
if (!onStage) stage.addChild(o);
var res:Point=new Point();
var rect:Rectangle=o.getRect(o);
res.x=-1*rect.x;
res.y=-1*rect.y;
if (!onStage) {
stage.removeChild(o);
if (p) p.addChild(o);
}
return res;
}

您不能。锚点未导出,仅存在于 * .fla 文件中。
但是,您可以实现自己的锚系统(就像许多库一样),但是无法访问原始fla中的那些。
