# ClothColliderEvents.NewBodyCollisions An event type that a cloth collider publishes (before simulation update) when cloth bodies collide with it. ``` struct NewBodyCollisions ``` ## Overview This event should be treated as having a non-escapable lifetime. Some of its data is no longer available after its lifetime has ended. ## Topics ### Accessing collision data [`func withCollisions((Span) -> Result) -> Result`](/documentation/RealityKit/ClothColliderEvents/NewBodyCollisions/withCollisions(_:)) Provides access to the collisions with cloth bodies that took place. [`struct Collision`](/documentation/RealityKit/ClothColliderEvents/NewBodyCollisions/Collision) A collision with a cloth body. ### Identifying the event [`let colliderEntity: Entity`](/documentation/RealityKit/ClothColliderEvents/NewBodyCollisions/colliderEntity) The entity that has the collider component that this event originates from. [`let updateCount: UInt64`](/documentation/RealityKit/ClothColliderEvents/NewBodyCollisions/updateCount) The simulation update that this event originates from. ## Relationships ### Conforms To [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Event`](/documentation/RealityKit/Event) [`Sendable`](/documentation/Swift/Sendable) --- Copyright © 2026 Apple Inc.
