Time to secure the connection between clients and gateways so packet sniffers and man in the middle attacks are a thing of the past

Give players the option to make their own accounts

Saving 'naked' passwords is always a bad idea. Use hashing and salting to ensure that if a database is leaked/stolen. The data will still be useless

Time to get into the fun stuff =) Spawning other players into the map

Syncing players up using world_state snapshots

Using interpolation to smooth the movement of other players

Extrapolating when our connection was hanging or packets were lost

Thank you Stefan! I found all of your tutorials to be the best source for practical, in-depth and real game building with Godot. Combine with the fundamentals and theory tutorials of the channel Godot Tutorials, it is the best way for me to understand the platform. Please keep up with the good work.

Spawning server-side enemies that are governed by the server

Syncing the animations across clients for both idle/walk/shoot

Creating server maps to remove hit detection from the client (this way the player can't fool the server anymore about what it hits)

And the implementation of that server-side hit detection

I also want to say a token of appreciation for the all these tutorials you have done to help us, really thanks they are very useful and not only helping Godot users but any users in general wanting to understand the topology, concept and way of building reliable online multiplayer games.

Thanks is not enough Stefan :) Bit hats off to you.

Great tutorial-series. But I had one large issue: When using the ms of the OS as a timestamp on the network messages I had my chracters jumping around for no reason even when they where not moved at all and the position did not change at all.

I could solve this by using a "handcounted" framenumber as a timestamp. I do not understand why it is like that but this is 100% reproducable for me.

Maybe this helps somebody else.
