Multiplayer

Vale-git

Hi, I'm a bit confused about how to implement multiplayer game.

In my project I have already a connection between clients and a server.

I choose to have a server who will handle just the info between clients - it don't have any scenes related to clients. When I load a client I load the map + the player. Because I want to have all graphics in client side.

I have to understand this "simple" concept: If in one client the player move his position how I can communicate that movement in the other clients through the server in the simplest way? What is the best approach using master/puppet functions?

Thanks

I'm not well versed in this, but my guess is you might package all the information you want to update in an array or something and update the server periodically (like sending packets of information)...then the server can read those and update that data appropriately..

BUT!!! there are some cosiderations... first, the data should probably be stored on the server side...e.g. health , mesh id(for display purposes),location, ammo or skills data etc. and the client would send their data, as well as, requesting data about the other players within a certain range or whatever.

second, depending on the number of players you would probably need to do some form of prediction...for movement or whatever or there will always appear to be rubber banding issues etc for other players.

It's the right idea to store the assets on the client side though...How you implement this stuff is the trick.

This book has a multiplayer chapter, I found it to be a pretty good resource: https://www.amazon.com/Godot-Engine-Development-Hours-Yourself-ebook/dp/B07BFDQFL9/

Agree with you so far. My doubt is about all things related with graphics like animation, effect etc. how I can share them with other clients? When I run 2 (or more) client sessions I have all of them by themselves. with just 1 player on it. To see the other player in my session what is the best approach? I have to spawn it in my map then sync it with what the other player do in his map? Or I have to approach another way?

EDIT: Maybe it is enough send just the keystrokes/mouse events? Then apply them to their toons? What do you think? Besides other things related to anti cheats control?

EDIT2: How I can manage to send my inputs only to the other toon in the other client? As I'm now all my input are received the other toon in my map. I'm so confused.... Maybe is too late and I'm tired.:)

There are both too generic. They don't explain how to resolve my problem.
