Enum MorphIndices 

pub enum MorphIndices {
    Uniform {
        current: HashMap<MainEntity, MorphIndex, EntityHash>,
        prev: HashMap<MainEntity, MorphIndex, EntityHash>,
    },
    Storage {
        morph_weights_info: HashMap<MainEntity, MorphWeightsInfo, EntityHash>,
        gpu_descriptor_indices: HashMap<MainEntity, MorphDescriptorIndex, EntityHash>,
        gpu_descriptor_free_list: Vec<MorphDescriptorIndex>,
    },
}

Maps each mesh affected by morph targets to the applicable offset within the MorphUniforms buffer.

We store both the current frame’s mapping and the previous frame’s mapping for the purposes of motion vector calculation.

Variants

Uniform

The variant used when storage buffers aren’t supported on the current platform.

Fields

current: HashMap<MainEntity, MorphIndex, EntityHash>

Maps each entity with a morphed mesh to the appropriate offset within MorphUniforms::current_buffer.

prev: HashMap<MainEntity, MorphIndex, EntityHash>

Maps each entity with a morphed mesh to the appropriate offset within MorphUniforms::prev_buffer.

Storage

The variant used when storage buffers are supported on the current platform.

Fields

morph_weights_info: HashMap<MainEntity, MorphWeightsInfo, EntityHash>

Maps each entity with a morphed mesh to the MorphWeightsInfo.

gpu_descriptor_indices: HashMap<MainEntity, MorphDescriptorIndex, EntityHash>

Maps each entity with a morphed mesh to the GpuMorphDescriptor in the morph_descriptors buffer.

gpu_descriptor_free_list: Vec<MorphDescriptorIndex>

Indices in the morph_descriptors buffer available for use.

Implementations

impl MorphIndices

pub fn morph_descriptor_index( &self, main_entity: MainEntity, ) -> Option<MorphDescriptorIndex>

Returns the index of the morph descriptor in the morph descriptor table for the given entity.

As morph descriptors are only present if the platform supports storage buffers, this method returns None if the platform doesn’t support them.

Trait Implementations

impl Component for MorphIndices

where MorphIndices: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::SparseSet

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have Component<Mutability = Mutable>, while immutable components will instead have Component<Mutability = Immutable>.

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn map_entities<M>(this: &mut MorphIndices, mapper: &mut M)

where M: EntityMapper,

Maps the entities on this component using the given EntityMapper. This is used to remap entities in contexts like scenes and entity cloning. When deriving Component, this is populated by annotating fields containing entities with #[entities]

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<MorphIndices>>

Returns ComponentRelationshipAccessor required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add ComponentHook for this Component if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert ComponentHook for this Component if one is defined.

fn on_discard() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_discard ComponentHook for this Component if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove ComponentHook for this Component if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn ComponentHook for this Component if one is defined.

impl FromWorld for MorphIndices

fn from_world(world: &mut World) -> MorphIndices

Creates Self using data from the given World.

impl Resource for MorphIndices

where MorphIndices: Send + Sync + 'static,
