Easy animations for GLTF files

Purpose

GLTF files include animations in their files. Importing them into bevy can be tedious, especially if you don't plan to blend any animations.

This crate automatically creates a handler for your animations per scene root based on the imported GLTF file.

Example

use bevy::prelude::*;
use bevy_gltf_animation::prelude::*;

fn main() {
    App::new()
        .add_plugins((DefaultPlugins, GltfAnimationPlugin))
        .add_systems(Startup, setup)
        .add_systems(Update, play_animations)
        .run();
}


fn setup(mut commands: Commands, asset_server: Res<AssetServer>) {
    // spawns a SceneRoot and GltfAnimations on this component
    commands.spawn(GltfSceneRoot::new(asset_server.load("human.glb")));
}
// once gltf animations have been added, play animation 2.
fn play_animations(
    animations: Query<&mut GltfAnimations, Added<GltfAnimations>>,
    mut players: Query<&mut AnimationPlayer>,
) {
    for mut gltf_animations in animations {
        let index = gltf_animations.get(2).unwrap();
        // if named, you can use
        // let index = gltf_animations.get("Walking_Forward").unwrap()
        let mut player = players.get_mut(gltf_animations.animation_player).unwrap();
        player.play(index);
    }
}
