Hmm, I've seem to have come across a problem with x value rotation with my camera. I've never really used 3D commands in DBC but I'm understanding fine. Just when I try to rotate my camera on the x axis it won't allow for negative value rotation. I know this is simple, but I'm stumped. How can I xrotate my camera with the upkey() and downkey() commands?

The usual command to 'wrap' the angle values is wrapvalue()
The negative value will be wrapped between 0 and 360.
Examples: wrapvalue(-5) = 360 - 5 = 355
wrapvalue(-720) = wrapvalue(360 - 720) = wrapvalue(-360) = wrapvalue(360 - 360) = 0



It's the programmer's life:
Have a problem, solve the problem, and have a new problem to solve.

I just figured it out earlier. I rotated the camera 360.0 then made 360.0 ground level and subtracted from there. Thanks

Well, that's exactly what wrapvalue does. But faster...
