I need tens of objects (cilinder mesh cooliders) interacting, is it possilbe?

Hi,

I’m creating a game where I need physical interaction between tens of objects, I think the average will ge around 50. Is this possible to accomplish with 3gs devices? My colliders should be cylinders but we all know unity (physx) doesn’t provide such primitive, so, I should use a mesh collider. Every mesh collider should be a cylinder of 12 sides. I have seen other games on the store (not unity) that do this and they work nicely. Has anybody tried to accomplish something like this with success on unity?

P.D. I have done some tests with 80 objects with a mesh collider created from a unity3d cilinder and it really lags. Could anyone give any insights please?

P.D. More data, I have just left 40 objects with just box colliders and still lags a lot. Don’t really know how I could get this better. On the other hand I have lowered the physics iteration to 3 too.

Thanks in advance.

If you can use a sphere collider and get close, that may help your speed quite a bit. How are your draw calls?

You need to set your solver iteration count low, your fixedupdate rate low and stick to spheres or box colliders, and it should be fine, yeah. Keep sleep fairly high.
