# Objective
- Closes#15716
- Closes#15718
## Solution
- Replace `Handle<MeshletMesh>` with a new `MeshletMesh3d` component
- As expected there were some random things that needed fixing:
- A couple tests were storing handles just to prevent them from being
dropped I believe, which seems to have been unnecessary in some.
- The `SpriteBundle` still had a `Handle<Image>` field. I've removed
this.
- Tests in `bevy_sprite` incorrectly added a `Handle<Image>` field
outside of the `Sprite` component.
- A few examples were still inserting `Handle`s, switched those to their
corresponding wrappers.
- 2 examples that were still querying for `Handle<Image>` were changed
to query `Sprite`
## Testing
- I've verified that the changed example work now
## Migration Guide
`Handle` can no longer be used as a `Component`. All existing Bevy types
using this pattern have been wrapped in their own semantically
meaningful type. You should do the same for any custom `Handle`
components your project needs.
The `Handle<MeshletMesh>` component is now `MeshletMesh3d`.
The `WithMeshletMesh` type alias has been removed. Use
`With<MeshletMesh3d>` instead.
# Objective
Add support for events that can be triggered from animation clips. This
is useful when you need something to happen at a specific time in an
animation. For example, playing a sound every time a characters feet
hits the ground when walking.
Closes#15494
## Solution
Added a new field to `AnimationClip`: `events`, which contains a list of
`AnimationEvent`s. These are automatically triggered in
`animate_targets` and `trigger_untargeted_animation_events`.
## Testing
Added a couple of tests and example (`animation_events.rs`) to make sure
events are triggered when expected.
---
## Showcase
`Events` need to also implement `AnimationEvent` and `Reflect` to be
used with animations.
```rust
#[derive(Event, AnimationEvent, Reflect)]
struct SomeEvent;
```
Events can be added to an `AnimationClip` by specifying a time and
event.
```rust
// trigger an event after 1.0 second
animation_clip.add_event(1.0, SomeEvent);
```
And optionally, providing a target id.
```rust
let id = AnimationTargetId::from_iter(["shoulder", "arm", "hand"]);
animation_clip.add_event_to_target(id, 1.0, HandEvent);
```
I modified the `animated_fox` example to show off the feature.
