globalTransformationMatrix property

Matrix globalTransformationMatrix

The global 2D transformation matrix of this display object.

Note: You can get the global transformation matrix either with the globalTransformationMatrix or the globalTransformationMatrix3D getter. You only need to use a 3D transformation matrix if you are working with 3D display objects.

Implementation

Matrix get globalTransformationMatrix {
  var result = Matrix.fromIdentity();

  for (var obj = this; obj != null; obj = obj.parent) {
    if (obj is DisplayObjectContainer3D) {
      throw StateError("Can't calculate 2D matrix for 3D display object.");
    } else {
      result.concat(obj.transformationMatrix);
    }
  }

  return result;
}
