How can I know if an angle is clock- or counterclockwise?

Rob92

I have a problem using the data from the JSON.
It appears that the rotation keyframes do not specify if an angle is clock, or counterclockwise.
This makes it impossible for me to interpolate between them.

JSON example:

lines 12-13 are clockwise
lines 25-26 are counter-clockwise.

How can I know that they are in my code if theres no information about it?

Thanks!

Spine currently doesn't store direction. It just interpolates to the closest angle.
A positive angle change is counterclockwise. A zero world rotation points the bone parallel to the +x axis.

Hi, thanks for your reply.

Because I use euler angles and not quaternions, it's hard to determine the shortest path towards an angle.
Is that even possible?
