SKAction continue working

I'm using the following to pause my game

self.scene?.paused = true

When the scene is paused, however, all SKActions stop. What can I do to allow some of the actions to continue to work?

Add certain nodes to different SKNode so instead you can only pause the the layer (SKNode) that you wish to pause. It would look something like this:

let gameLayer = SKNode() 
let pauseLayer = SKNode()

Now when you want to add a child to the scene, instead add it to a layer:

gameLayer.addChild(gameSceneNode)
pauseLayer.addChild(pauseSceneNode)

Don't forget to add the layers to the scene too

addChild(gameLayer)
addChild(pauseLayer)

To pause a layer write this:

Swift 3

gameLayer.isPaused = true

Swift 2

gameLayer.paused = true

Note that in this example, all the nodes on the gameLayer will be paused, however everything on the pauseLayer will not.

You need to design your node tree in a way where you can pause certain nodes (the gameplay nodes, for example), and not pause others (the pause menu nodes, for example). When you set the paused property on a node, it applies to all of its children as well.

An example node hierarchy:

GameScene
    GameplayNode
        Character
        Enemy
        Enemy
    PauseMenu
        PlayButton
        VolumeButton

If you want to animate your PlayButton while the game is paused, you can set the GameplayNode.paused to true, and still have working SKAction's for your pause menu.
