bevy | A refreshingly simple data-driven game engine built in Rust | Game Engine library

I want to send Events between the game client and server and I already got it working, but I do not know how to do it with bevy.

I am dependent to use tokios async TcpStream, because I have to be able to split the stream into a OwnedWriteHalf and OwnedReadhalf using stream.into_split().

My first idea was to just spawn a thread that handles the connection and then send the received events to a queue using mpsc::channel

Then I include this queue into a bevy resource using app.insert_resource(Queue) and pull events from it in the game loop.

the Queue:

I am currently working on a 3D voxel-based game and I want to have procedural generated chunks based on player movement.

But running the chunk generation in a simple system results in huge FPS drops.

I already tried to create a task pool that runs independent from everything else using std::sync::mpsc::channel, to generate the chunks data and mesh, which then gets requested by a normal bevy system, buffered and then spawned using commands.spawn(PbrBundle{...}).

I've been learning Bevy and I can't figure out how to simply rotate a sprite.

Here is a minimal example illustrating what appears to be a correctly rotated square but an incorrectly rotated rectangle with one dependency bevy = "0.6.1" and main.rs:

Some libraries such as Bevy or Actix Web have functions which accept user defined functions with any amount of parameters.

Examples:

Actix Web:

When attempting to print "Hello, world!" to the screen with Bevy, the text would not display until I imported a third-party font file and loaded it as an asset to use as the font value in the TextStyle value of the Text component. Prior to using that font, I had not explicitly specified the font; I just used the value from Default::default(), which is WeakHandle(Id(97059ac6-c9ba-4da9-95b6-bed82c3ce198, 0)). This seems to imply that Bevy is finding the wrong font or at least an unusable one by default. Is this more likely to be an issue with the font my system is offering up or with the Bevy default font functionality?

Here's a minimal reproducible example:

On Mac freshly upgraded to Monterey, I'm getting the following when attempting to cargo run a trivial Bevy program. I've reinstalled XCode CLTs like recommended here and other places. I've tried messing around with some of the cargo.yml with no success.

In the Bevy book the following code is used:

I have just started looking into the Bevy game engine for Rust. It has a feature called dynamic, which enables dynamic linking, to speed up compilation time during development. We are, however, advised to disable this when building for release.

Is there a way to tell Cargo to enable the dynamic feature for a debug build, but disable it for a release build? Or do I have to personally remember to change bevy = { version = "0.5.0", features = ["dynamic"] } to bevy = "0.5.0" in Cargo.toml before running cargo build --release?

I'm creating a vertical nav bar that I want fixed on the left hand side and for the container to take up the entire height of the window. It's fine and dandy until I scroll down. The pictures below will explain everything.
