Rotating Skeleton

hahanoob

I'm working on a top-down game and I'd like to be able to rotate my sprites. I'm using the spline-sfml runtime which didn't seem to support that but I assumed it should be trivial to add. So I was surprised to see that spSkeleton has world x and y but nothing for rotation. Am I missing something obvious? I'd prefer not to mess with the root bone since the animation might be driving that. I suppose I could transform the individual vertices but I wanted to check first. I can't imagine this isn't something that's come up before but when I tried searching these forums I didn't find much.

[edit] Runtime scaling too.

Rotating or scaling the root bone is the easiest way to do what you need. You can adjust the root bone's transform after you apply animations, but before you call updateWorldTransform.

Other toolkits (like those that are scene graphs) may have the skeleton in a container that can be rotated, but they pay a cost for that. You could do the same, eg by adjusting vertices before drawing, rotating your camera, etc.

Thanks for quick reply. That makes sense, the extra transform would probably be wasted on a sidescroller or something. I'll just reserve the root node for the runtime from now on.
