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
