# run(_:onChildWithName:) Creates an action that runs an action on a named child object. ``` class func run(_ action: SKAction, onChildWithName name: String) -> SKAction ``` ## Parameters `action` The action to execute. `name` The name of a child object. See the [`name`](/documentation/SpriteKit/SKNode/name) property on the [`SKNode`](/documentation/SpriteKit/SKNode) object. ## Return Value A new action object. ## Discussion Because this action references child nodes by name, it is especially handy for nodes that the scene subclass (or scene delegate) does not maintain a reference to, for example, child nodes that are defined in an `.sks` file. This action has an instantaneous duration, although the action executed on the child may have a duration of its own. When the action executes, it looks up an appropriate child node and calls its [`run(_:)`](/documentation/SpriteKit/SKNode/run(_:)) method, passing in the action to execute. This action is reversible; it tells the child to execute the reverse of the action specified by the `action` parameter. --- Copyright © 2026 Apple Inc.
