Bevy FPS Controller

Inspired from Source engine movement, this plugin implements movement suitable for FPS games.

Feel free to make issues/PRs!

Features

  • Air strafing and bunny hopping (hold down jump key)
  • Support for sloped ground
  • Crouching (prevents falling off ledges), sprinting
  • Noclip mode
  • Configurable settings

Examples

See main.rs

cargo run --release --example minimal
