# enumerateBodies(alongRayStart:end:using:) Enumerates all the physics bodies in the scene that intersect a ray. ``` func enumerateBodies(alongRayStart start: CGPoint, end: CGPoint, using block: @escaping (SKPhysicsBody, CGPoint, CGVector, UnsafeMutablePointer) -> Void) ``` ## Parameters `start` The starting point for the ray in scene coordinates. `end` The ending point for the ray in scene coordinates. `block` A block to be called for each physics body that the ray touches. The block takes the following parameters: - body: The physics body that the ray intersected. - point: The point in scene coordinates where the ray contacted the physics body. - normal: The normal vector for the physics body at the point of contact. - stop: A pointer to a Boolean variable. Your block can set this to to terminate the enumeration. --- Copyright © 2026 Apple Inc.
