Well, try to use a normal ent_move/ c_move movement code. Use a absolute vector for gravity. This gravity must be turned with a sin/cos instruction. It must be changed by every movement the actor does. The actor must have a pre-calculated position, where sin and cos calculations begin. Hm, it is like a third person camera, which turns around a player. If you move along a spere-model, you have to youse c_move, i think.

I havn't tested this idea. It's, well, an idea.

I try it out. If nobody understand it, im sory

it is a good idea with this spheres. Like in the game prey. I will post my solution if i succede (is this the right english word ?)

MfG,
