Realtime physics game on network?

Hi, I'm fairly new to online multiplayer games. I have a working local couch multiplayer game that's similar to bumper cars, where players try to push each other out of the arena. Naturally, physics-based collision between players is a core aspect of the game. I've tried implementing PUN for online multiplayer, but due to players being out of sync with the server, I'm seeing some weird behaviors like "ghost" collisions from lag. I've looked at things like lag compensation and prediction, but I'm starting to doubt if those methods help in my case, since those methods are bound to introduce input disparities and small dispositions that result in non-deterministic collision outcomes. What would be the smart way to overcome this issue?

 

Hi.

There has been a discussion about a similar problem on this thread:

However there is still no one fits all solution out there.

 

It really depends on your game what the right approach should be. Some games can get away with disabling all colliders on the clients and just syncing the transforms/rigidbodies for example, while others need a completely different approach.
