Is there any way to force PR_RotateEntity and PR_RotateEntityAbs rotate the entity around the -worldspace- coordinates instead of object''s coordinates. That would be really helpful. I''m trying to make a ball rotate so that it looks like its rolling on the floor, but using these functions, it rotates around the entity''s axis instead of the world''s axis, which doesn''t look right in this situation. -Rich PS. Maybe there is a better way to rotate objects than the PR_RotateEntity/Abs functions? Should I use matricies/quanternions?

You need a rotate about axis function. Quaternions can be used, or you could do it with matrices.
