How deterministic is this game?

[ValorZard]

Does this use Fixed Point numbers or soft floats to prevent desyncs?

Ultimately that's up to you. Here's what NetplayJS assumes:

• NetplayJS does not require that your game code be deterministic.
• By default NetplayJS assumes non-determinism and uses full state sync messages to keep players in sync with the host.
• If you can guarantee that your game code is deterministic, you can set Game.deterministic = true which turns off state sync messages and improves network utilization.
• This flag is enabled in the emulator and physics examples.

The next step is to ask what Javascript operations are deterministic and what operations are non-deterministic. Unfortunately it's a difficult question to answer, and I haven't seen a definitive exploration of this topic.
