Hello everyone!

Recently I have been beating my head against the wall trying implement and learn more about client-side prediction with rigidbodies in Godot and I have a few concerns on how I should be approaching this.

1. Is client side prediction impossible if physics is non-deterministic? I assume this to be true if we cannot predict the SAME exact outcome from every action.
2. Are rigid bodies in engines such as Godot and Unity something to avoid when trying to synchronize games over the network? I did some research on this and found some older posts from the past 5 years or so recommending against using Unity's built-in physics due to it not being deterministic, I am wondering if it is the same with Godot or not.
3. Regardless of the above, at this point I would assume coding the physics myself would be a lot easier and provide a lot more certainty when troubleshooting synchronization problems over the network.

I feel like I have made a fundamental error in using rigidbodies and would really appreciate any feedback on this.

Thanks a bunch in advance!

I am trying to make something fast paced with precise collisions and a similar feeling to Stick Fight. I do not have enough experience to visualize and know what the correct answer for something like this is.

So even when physics is non-deterministic corrections can be applied and still make for a smooth experience? I am struggling to understand the process  and picture the flow chart of making corrections feel smooth if they need to happen often.

I actually found a post on here that may shed some light on some of my confusion

I will study this and see where it goes.

Thank you
