Struct AnimManager 

pub struct AnimManager<'a> { /* private fields */ }

Animation manager that handles multiple animations.

This struct manages the lifecycle and playback of multiple animations. It is designed to be memory-efficient for embedded systems.

Type Parameters

• C - The callback type that implements AnimCallback
• N - The maximum number of simultaneous animations

Implementations

impl<'a> AnimManager<'a>

pub const fn new( animations: &'a mut [AnimInstance], anim_status: &'a [AnimStatus], ) -> Self

Creates a new animation manager.

pub fn add(&mut self, anim: Anim) -> Option<AnimId>

Adds an animation to the manager.

Arguments

• anim - The animation to add

Returns

The animation ID, or None if the manager is full.

pub fn remove(&mut self, id: AnimId) -> bool

Removes an animation from the manager.

Arguments

• id - The animation ID to remove

Returns

true if the animation was found and removed.

pub fn play(&mut self, id: AnimId) -> bool

Starts playing an animation.

Arguments

• id - The animation ID to play

Returns

true if the animation was found and started.

pub fn pause(&mut self, id: AnimId) -> bool

Pauses an animation.

Arguments

• id - The animation ID to pause

Returns

true if the animation was found and paused.

pub fn resume(&mut self, id: AnimId) -> bool

Resumes a paused animation.

Arguments

• id - The animation ID to resume

Returns

true if the animation was found and resumed.

pub fn stop(&mut self, id: AnimId) -> bool

Stops an animation.

Arguments

• id - The animation ID to stop

Returns

true if the animation was found and stopped.

pub fn get_state(&self, id: AnimId) -> Option<AnimState>

Gets the state of an animation.

Arguments

• id - The animation ID

Returns

The animation state, or None if not found.

pub fn tick(&mut self, elapsed: Duration)

Updates all active animations.

This method should be called regularly (e.g., in the main loop) with the elapsed time since the last update.

Arguments

• elapsed - Time elapsed since the last update

pub fn count(&self) -> usize

Returns the number of active animations.

pub fn is_empty(&self) -> bool

Returns whether there are any active animations.
