Can Achieve Deterministic Physics ?

Hello ,

How can I achieve same 3D physics simulation on different Devices.

I know that unity physics is not deterministic . But is there any way i can achieve deterministic physics ?

I’m trying to make a multi-player pool game .So sending transform of the balls every frame(or some defined interval) costs too much. So i was thinking to send Force and Direction only.

Round based is the best scenario. You only need one computer to do the simulation - all others just play it as an animation. Also the transfer of the data is very little and only needs to send data if actually something changes as reaction time is not important.
You also don’t need to send the whole transform. Only the position is important.

It gets complicated only if you have 2 players actively manipulating the physics at the same time e.g. in fps’s
