Net code

Pvp-related cloud function stored at cloudFunctions folder. Real-time networking is powered by a deterministic ping-pong model.

Here are some theses about net code to help you understand it better:

• Deterministic model powered by Mersenne twister random to be synced for both players - common seed provided by backend;
• The model implements time traveling: it means that you can place opponent input in past time what will change the present;
• The model fully syncs with opponent every 2.5 secs;
• The client sends ~10 direct messages per second to the opponent. Turns are used only for a game over announcement;
• Check out deterministic model's code here: https://github.com/red-machine-games/clash-of-cats-game/blob/master/src/model/deterministicPong.js

All networking is done with js SDK (https://github.com/red-machine-games/goblin-javascript-asset)
