# setUniformTransform(_:) Registers a closure that transforms a uniform value of type `V` on a per-entity basis. ``` func setUniformTransform(_ transform: @escaping (V, Entity) -> V) where V : BitwiseCopyable ``` ## Parameters `transform` A closure `(V, Entity) -> V`. ## Discussion The closure receives the current value and the entity being evaluated, and returns the transformed value. This lets you derive per-entity variants of a global uniform at simulation time, for example, converting a position from the scene’s coordinate system to the system’s coordinate system. --- Copyright © 2026 Apple Inc.
