There are multiple issues with this example.

  • The ClearColor which is meant to visually distinguish the first app from the next is never shown because there are no cameras. This has been broken between Bevy 0.7 and Bevy 0.8 with the Camera Driven Rendering stuff.

  • Since the recent winit upgrade, we get this error after the first window is closed.

thread 'main' panicked at 'Creating EventLoop multiple times is not supported.', /Users/robparrett/.cargo/registry/src/github.com-1ecc6299db9ec823/winit-0.27.4/src/event_loop.rs:106:13
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
  • Prior to that, I think this was still broken on at least MacOS with a different error after closing the first window.
