# rotate(byAngle:duration:) Creates an action that rotates the node by a relative value. ``` class func rotate(byAngle radians: CGFloat, duration: TimeInterval) -> SKAction ``` ## Parameters `radians` The amount to rotate the node, in radians. `duration` The duration of the animation. ## Return Value A new action object. ## Discussion When the action executes, the node’s [`zRotation`](/documentation/SpriteKit/SKNode/zRotation) property animates to the new angle. This action is reversible; the reverse is created as if the following code is executed: **Swift:** ```swift let action = SKAction.rotate(byAngle: -radians, duration: sec) ``` **Obj-C:** ```objc [SKAction rotateByAngle: -radians duration: sec]; ``` --- Copyright © 2026 Apple Inc.
