I am looking for help with Godot 3 to Godot 4 conversion with complex multiplayer code. How should this be made in order to work properly in Godot 4? Any suggestions and feedback are welcome. The project is from: https://github.com/loudsmilestudios/TetraForce . Tetra Force is in Godot 3. Of which efforts are being made in trying to properly convert the MIT Multiplayer ARPG into Godot 4.
An attempt to help.
There is a godot 3 plugin that might now be working called "Identity Service".
https://github.com/loudsmilestudios/TetraForce/tree/master/addons/identity-service I'm not entirely sure how this works it complex multiplayer code. Here is the 'Identity Service' addon in the github repo.
I tried this: 
Also this error. 
WithinAmnesia I tried this.
I got more bugs in a different script now but thats a lot of good progress so far lol.
Suggestions:
"Use FileAccess instead https://docs.godotengine.org/en/stable/classes/class_fileaccess.html ."
"You can use config file to store data. You can also use SQLite3."

This doc page is up to date for the HL api in 4.x "

Notes:
"Also, outside of you using a third party nuget library, there is no "Godot 4 .NET" networking vs "Godot 4 GDScript" networking. It's all the same engine API. The only differences are the engine API calls you make, which largely are just snake_case -> PascalCase, and having to sometimes force things into a Godot Collections object instead of being able to use nice C# native types (and other common c# godot pitfalls lol)."
" Generally the gist of how it's changed from what I understand (I never did networking in 3.x to know for sure) is some function name changes, and removing stuff like rset entirely and instead just you need to use an RPC to change values and stuff. Reading the old blog posts might provide some insight as well, but the code there won't necessarily be up to date as those were written while 4.0 was in development (the docs are more accurate/up to date). https://godotengine.org/article/multiplayer-changes-godot-4-0-report-1/
this is the first, it links all 4."
" Good luck! Porting this is not easy and might not be as iterative small step process as one hopes!
In some ways you're effectively rewriting the entire project in some parts. "
