Networking in Bevy/Rust: Bevy Renet Showcase

This is a showcase of the Renet networking plugin for the Bevy Game Engine. The underlying library should work with any other Rust game engine. I cover the basics of how the library is structured and walk through how to create a simple ping example from scratch.

For the MinimalPlugin running as fast as possible the solution is to add this resource before adding the `MinimalPlugin`:
/ 60.0))

5:14: I'm surprised and glad to see someone else using the port 42069. I use that for a lot of my projects.

[oglothenerd]

PLEASE make an updated version of this tutorial!

[Metruzanca]

5:32 - at this point I realized renet changed too much and if you're just following along, you'll just want to look at the bevy_renet examples.

Can't wait for the voxel game demo!

[TheScreamingFedora]

Wow I was literally planning on doing something similar for Bevy! I was going to implement a lockstep implementation though, but I might just use this instead. Awesome!

[AshtonSnapp]

Neat!

If only I was working on something with multiplayer.

[nate-wilkins]

This was a great resource for me. I did have one question though. For `client_receive_messages` should those fire off bevy events or be processed from the mut lists?
Probably could do either but idk which way would be more manageable

[wPederzoli]

Thanks for this video. It is great!
I might be missing something tho... I don't see the benefit of having bevy as a dependency on both ends (client and server) and having 2 game loops... It feels like a lot of overhead IMHO don't you think?

[halotroop]

4:15 Ah yes. The most logical thing to expect people to do... "Hey computer, exactly how long has it been since the universe began?" Why ask what time it is, when you could do that?

[SEOTADEO]

Your videos are really a gold mine. One question: When do you see a visual editor like Unity on the horizon for Bevy? I think the visualization of Unitys ECS is made quite nicely and I think something like it would work for bevy as well.

Hello, I wanted to ask how to connect to a public ip address? What do I need to change? I have port forwarded. Thanks.

[saicher]

Does it support UPnP so that you don't have to port forward?

[jeffg]

This is cool, thanks for sharing.
I'm planning on networking going through central server, but collisions and stuff on one of the clients, with failover to next client if first isn't reliable, and state stored on server in case failover needed (memory and db), but thought the physics would best be offloaded to a client to prevent on the processing on the server. Any thoughts on this architecture? Trying to both keep security (central server instead of p2p), but minimize server load as well. Even with WebGPU, could use compute shader on client for collision detection.

Can you recreate this video using the newest versions and if possible, cover how to use renet with the steam api? Thanks a lot

[devdev]

Great thanks. Would be interested in a server version without bevy and if this runs in wasm

[wadecodez]

Is there anything that you wish were different about this implementation?

[jeffg]

On the cheating front, for browser embedded games, it's probably kindof hard, right. Unless you bind the variables to javascript via bindgen, the user can't change any variables in the wasm itself (via browser tools), right? I haven't thought through it too much, but I feel we get away from the cheats a bit with WA. encrypt data sent if needed. Could even sign the WASM file as well.
