# Objective - Upgrade winit to v0.30 - Fixes https://github.com/bevyengine/bevy/issues/13331 ## Solution This is a rewrite/adaptation of the new trait system described and implemented in `winit` v0.30. ## Migration Guide The custom UserEvent is now renamed as WakeUp, used to wake up the loop if anything happens outside the app (a new [custom_user_event](https://github.com/bevyengine/bevy/pull/13366/files#diff-2de8c0a8d3028d0059a3d80ae31b2bbc1cde2595ce2d317ea378fe3e0cf6ef2d) shows this behavior. The internal `UpdateState` has been removed and replaced internally by the AppLifecycle. When changed, the AppLifecycle is sent as an event. The `UpdateMode` now accepts only two values: `Continuous` and `Reactive`, but the latter exposes 3 new properties to enable reactive to device, user or window events. The previous `UpdateMode::Reactive` is now equivalent to `UpdateMode::reactive()`, while `UpdateMode::ReactiveLowPower` to `UpdateMode::reactive_low_power()`. The `ApplicationLifecycle` has been renamed as `AppLifecycle`, and now contains the possible values of the application state inside the event loop: * `Idle`: the loop has not started yet * `Running` (previously called `Started`): the loop is running * `WillSuspend`: the loop is going to be suspended * `Suspended`: the loop is suspended * `WillResume`: the loop is going to be resumed Note: the `Resumed` state has been removed since the resumed app is just running. Finally, now that `winit` enables this, it extends the `WinitPlugin` to support custom events. ## Test platforms - [x] Windows - [x] MacOs - [x] Linux (x11) - [x] Linux (Wayland) - [x] Android - [x] iOS - [x] WASM/WebGPU - [x] WASM/WebGL2 ## Outstanding issues / regressions - [ ] iOS: build failed in CI - blocking, but may just be flakiness - [x] Cross-platform: when the window is maximised, changes in the scale factor don't apply, to make them apply one has to make the window smaller again. (Re-maximising keeps the updated scale factor) - non-blocking, but good to fix - [ ] Android: it's pretty easy to quickly open and close the app and then the music keeps playing when suspended. - non-blocking but worrying - [ ] Web: the application will hang when switching tabs - Not new, duplicate of https://github.com/bevyengine/bevy/issues/13486 - [ ] Cross-platform?: Screenshot failure, `ERROR present_frames: wgpu_core::present: No work has been submitted for this frame before` taking the first screenshot, but after pressing space - non-blocking, but good to fix --------- Co-authored-by: François <francois.mockers@vleue.com> |
