Built upon [bevy_gltf_components](https://crates.io/crates/bevy_gltf_components) this crate adds the ability to define Blueprints/Prefabs for [Bevy](https://bevyengine.org/) inside gltf files and spawn them in Bevy.
* Allows you to create lightweight levels, where all assets are different gltf files and loaded after the main level is loaded
* Allows you to spawn different entities from gtlf files at runtime in a clean manner, including simplified animation support !
A blueprint is a set of **overrideable** components + a hierarchy: ie
* just a Gltf file with Gltf_extras specifying components

## Animation
```bevy_gltf_blueprints``` provides some lightweight helpers to deal with animations stored in gltf files
* an ```Animations``` component that gets inserted into spawned (root) entities that contains a hashmap of all animations contained inside that entity/gltf file .
(this is a copy of the ```named_animations``` inside Bevy's gltf structures )
* an ```AnimationPlayerLink``` component that gets inserted into spawned (root) entities, to make it easier to trigger/ control animations than it usually is inside Bevy + Gltf files
The workflow for animations is as follows:
* create a gltf file with animations (using Blender & co) as you would normally do
* inside Bevy, use the ```bevy_gltf_blueprints``` boilerplate (see sections above), no specific setup beyond that is required
* to control the animation of an entity, you need to query for entities that have both ```AnimationPlayerLink``` and ```Animations``` components (added by ```bevy_gltf_blueprints```) AND entities with the ```AnimationPlayer``` component
For example:
```rust no_run
// example of changing animation of entities based on proximity to the player, for "fox" entities (Tag component)
pub fn animation_change_on_proximity_foxes(
players: Query<&GlobalTransform, With<Player>>,
animated_foxes: Query<(&GlobalTransform, &AnimationPlayerLink, &Animations ), With<Fox>>,
mut animation_players: Query<&mut AnimationPlayer>,
){
for player_transforms in players.iter() {
for (fox_tranforms, link, animations) in animated_foxes.iter() {
let distance = player_transforms
.translation()
.distance(fox_tranforms.translation());
let mut anim_name = "Walk";
if distance < 8.5 {
anim_name = "Run";
}
else if distance >= 8.5 && distance < 10.0{
anim_name = "Walk";
}
else if distance >= 10.0 && distance < 15.0{
anim_name = "Survey";
}
// now play the animation based on the chosen animation name
let mut animation_player = animation_players.get_mut(link.0).unwrap();
animation_player.play_with_transition(
animations.named_animations.get(anim_name).expect("animation name should be in the list").clone(),
Duration::from_secs(3)
).repeat();
}
}
}
```

# Animation demo
Example on how to control animations & how to use the provided helpers
Two animated blueprints are provided: Bevy's Fox, and a Robot I created.
There is almost no boilerplate, other than setting up ```Bevy_gltf_blueprints```
If you want to jump straight to controlling the imported animations, jump to :
[]('./game/in_game.rs#86')
## Running this example
```
cargo run --example animation --features bevy/dynamic_linking
