Only use code or watch video solution if you’re unsure how to solve or get stuck. It’s better to attempt writing the code first.


// Add comment code block in pauseGameplay() function

func pauseGameplay() {
    self.physicsWorld.speed = 0
    self.asteroidLayer.paused = true
    self.gameplayPaused = true

    // Add fade actions
    let fadeOutAction = SKAction.fadeOutWithDuration(1)
    let fadeInAction = SKAction.fadeInWithDuration(1)
    let fadeActionSequence = SKAction.sequence([fadeOutAction, fadeInAction])
    let fadeAnimation = SKAction.repeatActionForever(fadeActionSequence)
    // End Add face actions

    self.playerShip.runAction(fadeAnimation, withKey: "FadeAnimation")

// Add comment code block in unpauseGameplay() function

func unpauseGameplay() {

    self.physicsWorld.speed = 1
    self.asteroidLayer.paused = false
    self.gameplayPaused = false
    // Remove fade actions and set alpha back to 1
    self.playerShip.alpha = 1
    // End Remove fade actions and set alpha back to 1

If you also want to fade in/out asteroids, you have to add another action for asteroidLayer and comment out the asteroidLayer.paused = true statement in pauseGameplay() function.


Btw, your video is set to private, so can’t see it… :wink:


Thanks @ravenshore, I’ve changed the privacy and it should be OK later!


很 不错 ! :wink: Keep up the good work !
