I'm trying to make a game with an authoritative server. Here was an article about then concepts of a multiplayer game involving an authoritative server. After a lot of google searches this was the best demo I could find. The problem is that it doesn't demonstrate most of the concepts in the article. Is there a demo for Godot that demonstrates concepts from the article (Client Side Prediction, Server Reconciliation, Entity Interpolation, Lag Compensation ect..)?
