# move(by:duration:) Creates an action that moves a node relative to its current position. ``` class func move(by delta: SCNVector3, duration: TimeInterval) -> SCNAction ``` ## Parameters `delta` A vector that describes the change to be applied to the node’s position. `duration` The duration, in seconds, of the animation. ## Return Value A new action object. ## Discussion When the action executes, the node’s [`position`](/documentation/SceneKit/SCNNode/position) property animates from its current position to its new position. This action is reversible; the reverse is created as if the following code had been executed: ```objc SCNVector3 reverseDelta = SCNVector3Make(-delta.x, -delta.y, -delta.z); [SCNAction moveBy: reverseDelta duration: duration]; ``` --- Copyright © 2026 Apple Inc.
