I would REALLY like to know how to set the gravity inside of a sphere, that would be so freaking cool... fastlane do you think you could post up how you did it? It would be much appreciated!

inside a sphere?
-Gravity inside a hollow sphere is zero.
-Gravity at a certain radius inside a solid sphere depends on how much mass is contained within that radius.

In order to set Gravity in spheres in such, it's best to think in spherical coordiantes (rho, theta, phi). In this case, gravity will be constant in (theta, phi) and have the classic 1/(rho) squared behaiviour. Now you can convert this to Cartesian Coordinates to align them with the levels absolute coordinate

ummmmmmm, im really sorry but i didnt really catch much of that... I just would like to know how to make a sphere(a planet) on a game pull objects in twards it, much like earth, so you could just run around it and what-not. Me and my friends are making a game and we would like to know how to do that.

Hate to burst your bubble but making a spherical world will be challenging even without messing with these levels of maths. If the above doesn't make sense to you, you may be a bit over your head as regards a spherical environment.

Long story short, there is no quick and easy way to do this in 3DGS that I'm aware of. It can be done I think, but would require alot of coordiante transformation work and thus if you aren't comfortable with sperical, polar, and cartesian coordinate, then my advice is to "fake" the spherical world as has been suggested.

Ok man, thanks for your help, lol if you want to, you can add me to your msn or aim list. My name on aim is teelo888 and the msn email address is teelo888@msn.com. Hopefully you can help me with some other problems im having, if you cant, thats ok too.

Not big into the IM scene.
Just come by and ask here in the forums anytime you want!!
We'll be here!!
