Struct BlendAnimationsByIndex 

pub struct BlendAnimationsByIndex<T>
where
    T: EntityId,
{
    pub base: BasePoseNode<T>,
    pub index_parameter: String,
    pub inputs: Vec<IndexedBlendInput<T>>,
    pub prev_index: Cell<Option<u32>>,
    pub blend_time: Cell<f32>,
    pub output_pose: RefCell<AnimationPose<T>>,
}

A node that switches between given animations using index and smoothly blends from one animation to another while switching. It is very useful for situations when you need to switch between different animations. For example you could have an aim state, it is suitable for any weapon (you don’t need to create a ton of states like aim_rifle, aim_pistol, etc), but actual weapon holding animation should be different based on actual weapon a character is holding. In this case you create a BlendAnimationsByIndex node, add a few inputs where each input uses different weapon holding animation and in your game all you need to do is to set an index parameter in the machine parameters. The node will automatically perform smooth transition between different animations.

Fields

base: BasePoseNode<T>

Base node.

index_parameter: String

A name of index parameter that will be used to switch between input poses.

inputs: Vec<IndexedBlendInput<T>>

A set of input poses.

prev_index: Cell<Option<u32>>

Index of a previously active input pose.

blend_time: Cell<f32>

Current blend time.

output_pose: RefCell<AnimationPose<T>>

Output pose of the node.

Evaluates animation pose and returns a reference to it.

fn pose(&self) -> Ref<'_, AnimationPose<T>>

Returns a reference to inner pose of a node.

fn collect_animation_events( &self, nodes: &Pool<PoseNode<T>>, params: &ParameterContainer, animations: &AnimationContainer<T>, strategy: AnimationEventCollectionStrategy, ) -> Vec<(Handle<Animation<T>>, AnimationEvent)>

Collects animation events from internals.

impl<T> Clone for BlendAnimationsByIndex<T>

where T: Clone + EntityId,

fn clone(&self) -> BlendAnimationsByIndex<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for BlendAnimationsByIndex<T>

where T: Debug + EntityId,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T> Default for BlendAnimationsByIndex<T>

where T: Default + EntityId,

fn default() -> BlendAnimationsByIndex<T>

Returns the “default value” for a type.

impl<T> Deref for BlendAnimationsByIndex<T>

where T: EntityId,

type Target = BasePoseNode<T>

The resulting type after dereferencing.

fn deref(&self) -> &<BlendAnimationsByIndex<T> as Deref>::Target

Dereferences the value.

impl<T> DerefMut for BlendAnimationsByIndex<T>

where T: EntityId,

fn deref_mut(&mut self) -> &mut <BlendAnimationsByIndex<T> as Deref>::Target

Mutably dereferences the value.

impl<T> PartialEq for BlendAnimationsByIndex<T>

where T: PartialEq + EntityId,

fn eq(&self, other: &BlendAnimationsByIndex<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Reflect for BlendAnimationsByIndex<T>

where T: EntityId, BlendAnimationsByIndex<T>: 'static,

fn assembly_name(&self) -> &'static str

Returns a parent assembly name of the type that implements this trait. WARNING: You should use proc-macro (#[derive(Reflect)]) to ensure that this method will return correct assembly name. In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly. Alternatively, you can use env!("CARGO_PKG_NAME") as an implementation.

fn type_assembly_name() -> &'static str
