Struct bevy::prelude::AnimationTransitions

pub struct AnimationTransitions { /* private fields */ }

Manages fade-out of animation blend factors, allowing for smooth transitions between animations.

To use this component, place it on the same entity as the AnimationPlayer and bevy_asset::Handle<AnimationGraph>. It’ll take responsibility for adjusting the weight on the ActiveAnimation in order to fade out animations smoothly.

When using an AnimationTransitions component, you should play all animations through the AnimationTransitions::play method, rather than by directly manipulating the AnimationPlayer. Playing animations through the AnimationPlayer directly will cause the AnimationTransitions component to get confused about which animation is the “main” animation, and transitions will usually be incorrect as a result.

Implementations

impl AnimationTransitions

pub fn new() -> AnimationTransitions

Creates a new AnimationTransitions component, ready to be added to an entity with an AnimationPlayer.

pub fn play<'p>( &mut self, player: &'p mut AnimationPlayer, new_animation: NodeIndex, transition_duration: Duration ) -> &'p mut ActiveAnimation

Plays a new animation on the given AnimationPlayer, fading out any existing animations that were already playing over the transition_duration.

Pass Duration::ZERO to instantly switch to a new animation, avoiding any transition.

pub fn get_main_animation(&self) -> Option<NodeIndex>

Obtain the currently playing main animation.
