# animatedValueType A value that defines the type that the action animates, if the action animates a target value. ``` var animatedValueType: (any AnimatableData.Type)? { get } ``` ## Discussion In your implementation, return a type that matches the action animation’s bind target. For example if the action animates a [`Transform`](/documentation/RealityKit/Transform), return `Transform.self` in your implementation, and set the action animation’s bind target to [`BindTarget.transform`](/documentation/RealityKit/BindTarget/transform) when creating an [`AnimationResource`](/documentation/RealityKit/AnimationResource) with `AnimationResource.makeActionAnimation(...)`. --- Copyright © 2026 Apple Inc.
