Ichun (行ちゅん)

bevy-ichun (Okinawan dialect for the Japanese word 行く, meaning 'to go') is a simple kinematic character controller for Bevy with Avian3D.

Versions

Features

This library has three main components:

Kcc

The Kcc component provides the basic functionality for a kinematic character controller:

• applying gravity
• handling slopes
• collision handling with static geometry

Kcc movement (enabled by default kcc_movement)

The KccMovementConfig component provides events which can be used to move the Kcc around:

• moving
• jumping
• rotating

Kcc input (enabled by default kcc_input)

This component handles user defined input and uses the kcc_movement to move the Kcc around.

• forward, backward, left and right
• jump
• optional key to activate roation
• disable input handling for each Kcc & globally

Defining a key to handle roation is not yet implemented (the mouse is used). This feature is depending on the kcc_movement.

Examples

Examples are in the examples folder. It can be run with following command: cargo r --example simple-kcc
