I'm using a mirrored texture and its region to scroll it along its Y axis infinitely. The problem comes when trying to rotate the scrolling texture. It seems that its pivot point scrolls along with the texture. As such it gives the impression while testing that the rotation gets faster over time, but this is only the result of the pivot being continuously offset more and more.
My question is, seeing as the sprite node doesn't seem to have access to any pivot property, or set_pivot function, how would I go about updating the pivot, or at least, see to it that it is not being offset along with the texture.
