Framepacing and framelimiting for Bevy
https://github.com/aevyrie/bevy_framepace.git
rs
app.add_plugins(bevy_framepace::FramepacePlugin);
`
By default, the plugin will automatically measure your framerate and use this for framepacing.
You can adjust the framerate limit at runtime by modifying theFramepaceSettings resource. For
example, to set the framerate limit to 30fps:
`rs
settings.limiter = Limiter::from_framerate(30.0),
`
See demo.rs in the examples folder, or run with:
`console
cargo run --release --example demo
`
## How it works
The plugin works by recording how long it takes to render each frame, and sleeping the main thread
until the desired frametime is reached. This ensures the next frame isn't started until the very
last moment, delaying the event loop from restarting. By delaying the event loop, and thus input
collection, this reduces motion-to-photon latency by moving reading input closer to rendering the
frame.
The spinsleep dependency is needed for precise sleep times. The sleep function in the standard
library is not accurate enough for this application, especially on Windows.
## Bevy Version Support
I intend to track the main branch of Bevy. PRs supporting this are welcome!
