I am trying to rotate a popup on a mobile device when the device rotates. The popup is a sprite and it contains children text fields. When I use rotation:"-=90" the sprite rotates, but the text disappears until I have rotated it 360. However, rotationZ will rotate the text children with the sprite. But with rotationZ I cannot find any way to redefine the registration point for the rotation to the center of the sprite. TransformAroundCenter and TransformAroundPoint work will for rotation, but I can't seem to get them to work for rotationZ.
I am just starting to use Greensock. I am part way through the Noble text, but I might be missing some things that are specific to the AS3 version of Greensock.
I attempted to upload a file, but it would not upload a file of type .as
