Posted 2021-05-23

function flipHorizontal(dsp:DisplayObject):void {
	var matrix:Matrix = dsp.transform.matrix;
	matrix.a = -1;
	matrix.tx = dsp.width + dsp.x;
	dsp.transform.matrix = matrix;
}

function flipVertical(dsp:DisplayObject):void {
	var matrix:Matrix = dsp.transform.matrix;
	matrix.d = -1;
	matrix.ty = dsp.height + dsp.y;
	dsp.transform.matrix = matrix;
}
