Struct AnimationClip 

pub struct AnimationClip { /* private fields */ }

A list of VariableCurves and the AnimationTargetIds to which they apply.

Because animation clips refer to targets by UUID, they can target any AnimationTarget with that ID.

Implementations

impl AnimationClip

pub fn curves( &self, ) -> &HashMap<AnimationTargetId, Vec<VariableCurve>, NoOpHash>

VariableCurves for each animation target. Indexed by the AnimationTargetId.

pub fn curves_mut( &mut self, ) -> &mut HashMap<AnimationTargetId, Vec<VariableCurve>, NoOpHash>

Get mutable references of VariableCurves for each animation target. Indexed by the AnimationTargetId.

pub fn curves_for_target( &self, target_id: AnimationTargetId, ) -> Option<&Vec<VariableCurve>>

Gets the curves for a single animation target.

Returns None if this clip doesn’t animate the target.

pub fn curves_for_target_mut( &mut self, target_id: AnimationTargetId, ) -> Option<&mut Vec<VariableCurve>>

Gets mutable references of the curves for a single animation target.

Returns None if this clip doesn’t animate the target.

pub fn duration(&self) -> f32

Duration of the clip, represented in seconds.

pub fn set_duration(&mut self, duration_sec: f32)

Set the duration of the clip in seconds.

pub fn add_curve_to_target( &mut self, target_id: AnimationTargetId, curve: impl AnimationCurve, )

Adds an AnimationCurve to an AnimationTarget named by an AnimationTargetId.

If the curve extends beyond the current duration of this clip, this method lengthens this clip to include the entire time span that the curve covers.

More specifically:

• This clip will be sampled on the interval [0, duration].
• Each curve in the clip is sampled by first clamping the sample time to its domain.
• Curves that extend forever never contribute to the duration.

For example, a curve with domain [2, 5] will extend the clip to cover [0, 5] when added and will produce the same output on the entire interval [0, 2] because these time values all get clamped to 2.

By contrast, a curve with domain [-10, ∞] will never extend the clip duration when added and will be sampled only on [0, duration], ignoring all negative time values.

pub fn add_variable_curve_to_target( &mut self, target_id: AnimationTargetId, variable_curve: VariableCurve, )

Like add_curve_to_target, but adding a VariableCurve directly.

Under normal circumstances, that method is generally more convenient.

pub fn add_event(&mut self, time: f32, event: impl Event + Clone)

Add a untargeted Event to this AnimationClip.

The event will be cloned and triggered on the AnimationPlayer entity once the time (in seconds) is reached in the animation.

See also add_event_to_target.

pub fn add_event_to_target( &mut self, target_id: AnimationTargetId, time: f32, event: impl Event + Clone, )

Add an Event to an AnimationTarget named by an AnimationTargetId.

The event will be cloned and triggered on the entity matching the target once the time (in seconds) is reached in the animation.

Use add_event instead if you don’t have a specific target.

pub fn add_event_fn( &mut self, time: f32, func: impl Fn(&mut Commands<'_, '_>, Entity, f32, f32) + Send + Sync + 'static, )

Add a untargeted event function to this AnimationClip.

The func will trigger on the AnimationPlayer entity once the time (in seconds) is reached in the animation.

For a simpler Event-based alternative, see AnimationClip::add_event. See also add_event_to_target.

clip.add_event_fn(1.0, |commands, entity, time, weight| {
  println!("Animation Event Triggered {entity:#?} at time {time} with weight {weight}");
})

pub fn add_event_fn_to_target( &mut self, target_id: AnimationTargetId, time: f32, func: impl Fn(&mut Commands<'_, '_>, Entity, f32, f32) + Send + Sync + 'static, )

Add an event function to an AnimationTarget named by an AnimationTargetId.

The func will trigger on the entity matching the target once the time (in seconds) is reached in the animation.

For a simpler Event-based alternative, see AnimationClip::add_event_to_target. Use add_event instead if you don’t have a specific target.

clip.add_event_fn_to_target(AnimationTargetId::from_iter(["Arm", "Hand"]), 1.0, |commands, entity, time, weight| {
  println!("Animation Event Triggered {entity:#?} at time {time} with weight {weight}");
})
