collisions

if i were to make 2 gears, how would i get it to where i could make one move and the other would move too? like in the game room

In the game engine? If so this belongs in the game engine forum

Triangle mesh bounds and constraints

Or you could animate them by hands, which is probably more practical and more efficient.

Oh, I thought he meant with physics/real time. Either way works, but unless necessary use Egans method.

ya i could animate them by hand but im going to make a machine and have many gears so i think the physics would be better. should i post this in the game section?

No, it’s already pretty much answered. Just google for some animating tutorials.
