Crate wde_animation 

Rigid-part animation for WaterDropEngine.

A model is animated by moving rigid parts: each part hangs under an AnimationBone entity, whose transform is driven by an AnimationClip (one keyframe track per bone name). An AnimationPlayer on the root of the hierarchy plays and crossfades clips onto every bone below it.

Example

glTF models with %B%<bone> nodes spawn their bones automatically, and expose their clips:

fn walk(mut players: Query<&mut AnimationPlayer>, gltf: Res<Assets<GltfAsset>>, model: Res<Model>) {
    let walk = gltf.get(&model.0).unwrap().animation("Walk").unwrap();
    for mut player in &mut players {
        player.crossfade(walk.clone(), 0.2).set_speed(1.5);
    }
}

Structs

AnimationBone

Rigid part of an animated model, posed by the AnimationPlayer of its closest ancestor.

AnimationClip

Keyframed animation of a set of bones, identified by name.

AnimationPlayer

Plays clips (looping, or once) on the AnimationBones below its entity, blending smoothly from one clip to the next.

AnimationPlugin

AnimationSystems

Systems advancing the players and posing the bones, in [Update].

BoneTrack

Animation of one bone. Missing channels keep the bone’s rest value.

Keyframes

Values over time, sorted by time.

Enums

Interpolation

How values are interpolated between two keyframes.
