Automatic centering of sprite's origin

NewSorry

So I'm very new still, and I'm working on simple rolling/bouncing ball animations. Is there a way to set the rotation origin of a perfectly round and circular ball to the EXACT center of the sprite? I've been looking and can't seem to find any information on this seemingly primal feature. Thanks in advance!

If the ball is an actual circle drawn with a circle tool, and you properly cropped its image, you can do this:

Switch your transform space to Local

and then select your cropped ball attachment, set the position to 0, 0.
That will cause the attachment to be centered right where the bone is.

Depending on how small it is, or some extra pixels because of antialiasing or whatever, the pivot may be off by a pixel or even half a pixel.
That's not something that could be reasonably expected of Spine to account for anyway, so you can offset your attachment by 1, 1, or .5, .5 or whatever.

Thanks so much. Just figured it'd be a feature (a click to center bone/origin) , as opposed to a process of just zeroing it out. It works great thanks again.

If you wanted it to start that way when you add the image, you could also have dragged the image into a bone in the tree, instead of dragging it onto the viewport. That makes it so that it's centered on that bone to begin with (the local position is 0, 0 by default).

Though this requires that you had the bone before you had the slot and attachment.
