Struct AnimationPlayer

pub struct AnimationPlayer { /* private fields */ }

Animation controls.

Automatically added to any root animations of a scene when it is spawned.

Implementations

impl AnimationPlayer

pub fn start(&mut self, animation: NodeIndex) -> &mut ActiveAnimation

Start playing an animation, restarting it if necessary.

pub fn play(&mut self, animation: NodeIndex) -> &mut ActiveAnimation

Start playing an animation, unless the requested animation is already playing.
