# 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.  --------- Co-authored-by: Matty <weatherleymatthew@gmail.com> Co-authored-by: Chris Biscardi <chris@christopherbiscardi.com> Co-authored-by: François Mockers <francois.mockers@vleue.com> |
