Question about rotation angle

jiyu

Hello,

I just have one question about the rotation angle.

Loading Image
Like image above in setup mode, setup root at rotate 0 and translate 0. And setup bone with root as parent, then rotate 90 degrees.

Loading Image
After that setup image with bone as parent, the image has rotation value of 270 like above image.

At this time bone's rotation value and image's rotation value always turns up 360.

With this rotation value it looks like something like this happens http://esotericsoftware.com/forum/viewtopic.php?f=9&t=1808&p=11268#p11268

Can anyone explain why bone and image rotation value add up to 360?

Thanks.

Oh, by the way sometimes, rarely, I see rotation value that is over 360 like 368 or 372.

I think they only add up to 360 in your example. The rotation of the image is changed when attached to the bone so that the world rotation stayse same - the image doesn't move when attached.
