# BindTarget

A reference to a particular scene, entity, or property that animates.

```
enum BindTarget
```

## Overview

This structure describes a reference to an animated property. The property
may be a transform, collection of joint transforms, an arbitrary named
property of an entity, or the property of a nested entity.

For nested entities, the [`BindTarget.path(_:)`](/documentation/RealityKit/BindTarget/path(_:)) case returns a [`BindPath`](/documentation/RealityKit/BindPath)
instance that contains an array of *parts* ([`BindPath.Part`](/documentation/RealityKit/BindPath/Part)). Each part
identifies one or more nested, named entities or scenes, followed by the
property to animate.

## Topics

### Choosing a bind target

[`case `internal`(InternalBindPath)`](/documentation/RealityKit/BindTarget/internal(_:))

A bind target that refers to a framework-provided property.

[`case jointTransforms`](/documentation/RealityKit/BindTarget/jointTransforms)

An option that specifies that the entity’s joint transforms animate.

[`case parameter(String)`](/documentation/RealityKit/BindTarget/parameter(_:))

Provides a property that animates from the given textual name.

[`case path(BindPath)`](/documentation/RealityKit/BindTarget/path(_:))

Provides a complex bind path capable of animating additional entities
other than the current entity.

[`case transform`](/documentation/RealityKit/BindTarget/transform)

A option that specifies that the target entity’s transform animates.

### Targeting entities and scenes

[`static func scene(String) -> BindTarget.ScenePath`](/documentation/RealityKit/BindTarget/scene(_:))

Generates a bind path from a particular scene.

[`struct ScenePath`](/documentation/RealityKit/BindTarget/ScenePath)

A bind path for a particular scene.

[`static func anchorEntity(String) -> BindTarget.EntityPath`](/documentation/RealityKit/BindTarget/anchorEntity(_:))

Generates a complex bind path from a particular anchor entity in the
scene.

[`static func entity(String) -> BindTarget.EntityPath`](/documentation/RealityKit/BindTarget/entity(_:))

Generates a complex bind path from a particular child entity of the
current entity.

[`struct EntityPath`](/documentation/RealityKit/BindTarget/EntityPath)

A bind path context for a particular entity.

### Animatable properties

[`case opacity`](/documentation/RealityKit/BindTarget/opacity)

An option that specifies that the entity’s opacity to animate. Requires that
the entity has an OpacityComponent

[`case billboardBlendFactor`](/documentation/RealityKit/BindTarget/billboardBlendFactor)

[`case blendShapeWeights`](/documentation/RealityKit/BindTarget/blendShapeWeights)

An option the entity’s blend shape weights animate. Requires that the
entity has a BlendShapeWeightsComponent.

[`case skeletalPose(String)`](/documentation/RealityKit/BindTarget/skeletalPose(_:))

An option that specifies one of the entity’s skeletal poses to animate.

[`case blendShapeWeightsAtIndex(Int)`](/documentation/RealityKit/BindTarget/blendShapeWeightsAtIndex(_:))

[`case blendShapeWeightsWithID(BlendShapeWeightsData.ID)`](/documentation/RealityKit/BindTarget/blendShapeWeightsWithID(_:))

[`static func material(Int) -> BindTarget.MaterialPath`](/documentation/RealityKit/BindTarget/material(_:))

Generates a complex bind path from one of an entity’s materials.

[`struct MaterialPath`](/documentation/RealityKit/BindTarget/MaterialPath)

Material parameters that an animation can target.

[`struct TextureCoordinateTransformPath`](/documentation/RealityKit/BindTarget/TextureCoordinateTransformPath)

The texture coordinate parameters for a given texture layer that an animation can target.

[`struct IkSolverPath`](/documentation/RealityKit/BindTarget/IkSolverPath)

### Binding to root motion

[`case rootMotion`](/documentation/RealityKit/BindTarget/rootMotion)

A target that drives an entity’s root motion.

### Operators

[`static func == (BindTarget, BindTarget) -> Bool`](/documentation/RealityKit/BindTarget/==(_:_:))

Returns a Boolean value that indicates whether two bind targets are
equal.

## Relationships

### Conforms To

[`Equatable`](/documentation/Swift/Equatable)
