            How to connect bevy game to externel TCP server using tokios async TcpStream?
            Asked 2022-Mar-27 at 15:13

            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:



            Answered 2022-Mar-27 at 15:13

            I got it to work by just replacing every tokio::sync::mpsc with crossbeam::channel, which might be a problem, as it does block

            and manually initializing the tokio runtime.

            so the init code looks like this:



            How to make async system function in the bevy game engine?
            Asked 2022-Mar-18 at 14:53

            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{...}).



            Answered 2022-Mar-18 at 14:53

            bevy::tasks::AsyncComputeTaskPool wrappend in bevy::tasks::Task was the method I was searching for.

            I now have a system that inserts a task into each chunk to generate itself and then poll for this task in another function like this:



            How to rotate a rectangle in Bevy?
            Asked 2022-Mar-14 at 07:26

            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



            Answered 2022-Mar-14 at 07:26

            You should have better described what you mean by "incorrectly rotated rectangle". In fact your code does exactly what one would expect.

            However I think the issue that you are describing is that because you scaled your sprite using the Transform along the coordinate axes and then rotate the sprite, the scaling axes stay fixed which leads to the effect that the rectangle is constantly scaled differently while rotating. You can see this easily when using the rotate_system below with your original code.

            So how do you set the size of the sprite in its local frame? One would use the custom_size for this as shown below and then set the scale of the Transform to Vec3::new(1f32, 1f32, 1f32).

            I think you want to rotate the rectangle like so based on your code:



            Function variable with dynamic function parameters
            Asked 2022-Feb-11 at 17:17

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


            Actix Web:



            Answered 2022-Feb-11 at 16:40

            Since functions can implement traits, the solution is to define a trait that represents "can serve as callback function" and then manually implement it for every function arity up to some large number of arguments. In actix, this is done by having .to(f) take something implementing the Handler trait:



            Is the default font in Bevy unusable?
            Asked 2022-Jan-31 at 09:53

            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:



            Answered 2022-Jan-31 at 09:53

            Bevy does not offer a default font as of now.

            There was this closed PR to add one and there are several open issues connected to this, like this or that one.

            That said, I think it is confusing that it is possible to do:

            Asked 2021-Dec-10 at 22:13

            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.



            Answered 2021-Dec-10 at 22:13

            So I found a solution if you discover this issue and the code works on other machines. Uninstall rust with rustup self uninstall and then renistall with the standard script curl --proto '=https' --tlsv1.2 -sSf | sh and then you should be good.

            Can I activate a dependency's feature only for debug profile?
            Asked 2021-Oct-29 at 23:18

            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?

            Vertical Nav bar separates from header when I scroll
            Asked 2021-Jul-28 at 05:53

            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.

            Looks fine here

            Looks not fine here




            Answered 2021-Jul-27 at 23:32

            If you want to scroll with header and nav(sidenav) then you should fixed header too and if you want scroll with only sidenav then you should go with sticky like this
