The pros and cons of Lag CompensationJune 25, 2024 Tutorials NetworkingGames that are played over the network inevitably experience a delay, known as network latency or simply latency. As a result, every player is generally shown an outdated game world in real-time games. How outdated the displayed game world is depends on the respective latency. For this reason, the player must take their own latency into consideration in competitive games and, for example, in shooters, take into account not only the distance and bullet speed but also their own latency when aiming, and accordingly aim a little further in the assumed direction of the opponent.
Latency correlates to Server FPSAugust 13, 2023 Misc Godot Engine NetworkingI had already shown in the Tutorial to the World-Server-Login that one can query the so-called packet round trip time (RTT) with an active ENet connection over get_statistic( ENetPacketPeer.PEER_ROUND_TRIP_TIME).

To understand the problem a bit better, I should perhaps first explain that you cannot transfer every datatype via RPC or MultiplayerSynchronizer over the network, but only scalar datatypes.

In addition to the synchronization interval, the MultiplayerSynchronizer has other configuration options that can be used to do interesting things.

I had written then about the supported DTLS version: “I couldn’t find out yet which version is used by Godot, but as soon as I know, I will tell you.” And now is the time to share this information with you.

Unfortunately I couldn’t think of a better positioning, but I hope you can cope with it. After the tutorial series, which offers a good basic framework, today’s tutorial is about a topic that you can really see. The example shown here is based on a blog post by Fabio Alessandrelli, one of the main developers for the Godot network functionality. And since I don’t want to just copy everything, here’s how you can also use the techniques shown there when using path-dependent multiplayer APIs.

However, before using it in real life, we should first secure our network connections. The least one should do and, if I understand the GDPR correctly, must do, is to transmit user passwords only using encrypted channels on the Internet. Ideally, one extends encrypted communication to the entire infrastructure. So that’s what this article is going to be about: We encrypt the network connections between our servers and clients.

This token should now be used to log in to the world server. Therefore, in this article, we will extend the game client so that it forwards the token to the world server, and then enable the world server to verify the token.
