not bad, i like it

Thanks

Not finished though, there are still some flaws I hope I can fix.

by the way, I still need some help. If anyone could take a look at my code I would apreciate any help

Nice contribution, but there is still Gimbal lock on the top of the sphere
Is player uses normal to surface, or he is using the center of the sphere?

It uses the center of the sphere. I dont want to use the surface's normal because then, when he is on a steep slope he will not be at a strange angle. (would get a wierd effect looking like matrix wall-walking)

Yep, you are experiencing gimbal lock.
when the game "prey" came out, I did a spherical world demo
and an "any orientation" wall walking demo that dosent
experience gimbal lock . Check those out to see my solution.

I have downloaded several times the "prey_.zip" file in the link "Wall And Ceiling Walking Demo" in your signature, but when I try to unzip it with winrar or 7zip I always get an error.

Same here. "Unexpected end fof archive"
And theres no source in there. (due to the error?)
Any chance of seeing the source code?

in the past I had this same problem with another file. and when it was re-compressed and re-uploaded it worked.

Thanks for letting me know, the zip was indeed bad. I managed to find the original source, recompile it, and upload it. Should be fine now.
