SceneKit Camera Animation Moving and Deceleration

Question

I'm moving the camera node of my SCNScene scene along the z-axis using the following code:

let moveTo = SCNAction.moveTo(SCNVector3(x:0,y:0,z:-40), duration: 40); 
cameraNode.runAction(moveTo)

I would like given an event (like GameOver event fired by my game) to smoothly decelerate the camera until stop it.

How can smoothly stop moving the camera?

This is a very old post, but this comment may help someone. I'm not sure if it would work in this case, but you can do: `gameView.defaultCameraController.inertiaFriction = 0.01` — George, Oct 10 '18 at 17:12

SCNAction has a "timingMode" property you can set to "EaseOut"

The problem is that camerNode has associated a running action with duration 40 sec. Now I would like to stop moving the cameraNode. I can remove all action associated with the camera node but in this way cameraNode will not smoothly decelerate... – chiarotto.alessandro Aug 06 '15 at 20:59

Messy, but you could use Physics:

At the moment the GameOver event is fired, add a dynamic physics body to the node of the camera, give it the current velocity of the camera, and apply damping to make it slow down. This will give a vast amount of control of the slowdown, too. Just be sure the node is not subject to gravity, as that will see it fall without grace.
