当玩家死亡时，显示我新添加的间隙(ADMOB)

Question

我已经在游戏中添加了一些间隙广告。截至目前，我将广告连接到屏幕中心的按钮。我想做的是每当玩家死亡时自动显示广告。有谁知道如何做到这一点？

这是我的间隙广告的代码：

import UIKit
import SpriteKit
import GameplayKit
import GoogleMobileAds
//I added this
protocol GameInterstitialDelegate {
func openInterstitial()
}

class GameViewController: UIViewController, GADBannerViewDelegate, 
GADInterstitialDelegate {
var fullScreenAds :GADInterstitial!
//I added this
extension GameViewController: GameInterstitialDelegate {
    func openInterstitial() {
        self.fullScreenAds = CreateAndLoadInterstitial()
    }
}
func CreateAndLoadInterstitial() -> GADInterstitial? {
    fullScreenAds = GADInterstitial(adUnitID: "ca-app-pub-
6532333990655924/8291640688")
    guard let fullScreenAds = fullScreenAds else {
        return nil
    }
    let request = GADRequest()
    request.testDevices = [kGADSimulatorID]
    fullScreenAds.load(request)
    fullScreenAds.delegate = self
    return fullScreenAds
}
func interstitialDidReceiveAd(_ ad: GADInterstitial) {
    print("ads loaded")
    ad.present(fromRootViewController: self)
}
func interstitialDidFail(toPresentScreen ad: GADInterstitial) {
    print("ad did not load")
}
}

这是我的玩家功能：

class GameScene: SKScene {
//I added this
weak var interstitialDelegate: GameInterstitialDelegate?
//I added this
var gameScene = GameScene(fileNamed: "GameScene")
gameScene.interstitialDelegate = self
func playedDied() {
    self.removeAction(forKey: "SpawnCar2")
    self.removeAction(forKey: "SpawnCar3")
    self.removeAction(forKey: "SpawnCoin")
    for child in children {
        if child.name == "Car2" {
            child.removeAction(forKey: "MoveCar2")
        } else if child.name == "Car3" {
            child.removeAction(forKey: "MoveCar3")
        } else if child.name == "Coin" {
            child.removeAction(forKey: "MoveCoin")
        }
    }
    isAlive = false
    let highscore = GameManager.instance.getHighscore()
    if highscore < score {
        GameManager.instance.setHighscore(highscore: score)
    }
    let retry = SKSpriteNode(imageNamed: "Retry")
    let quit = SKSpriteNode(imageNamed: "Quit")
    retry.name = "Retry"
    retry.anchorPoint = CGPoint(x: 0.5, y: 0.5)
    retry.position = CGPoint(x: -150, y: -150)
    retry.zPosition = 7
    retry.setScale(0)
    quit.name = "Quit"
    quit.anchorPoint = CGPoint(x: 0.5, y: 0.5)
    quit.position = CGPoint(x: 150, y: -150)
    quit.zPosition = 7
    quit.setScale(0)
    let scaleUp = SKAction.scale(to: 0.8, duration: TimeInterval(0.5))
    retry.run(scaleUp)
    quit.run(scaleUp)
    self.addChild(retry)
    self.addChild(quit)
    //I added this
    interstitialDelegate?.openInterstitial()
}
}

override func touchesBegan(_ touches: Set<UITouch>, with event: 
UIEvent?) {
    for touch in touches {
        let location = touch.location(in: self)
        if atPoint(location).name == "Play" {
            gameplay!.scaleMode = .aspectFill
            self.view?.presentScene(gameplay!, transition: 
            SKTransition.fade(withDuration: TimeInterval(1)))
        }
        if atPoint(location).name == "Highscore" {
            scoreLabel.removeFromParent()
            createLabel()
        }
    }
}

编辑：我已经在SpriteKit上进行了更多搜索，看来做您想做的事情的简便方法是通知。

UIViewController:

class GameViewController: UIViewController, GADBannerViewDelegate, 
GADInterstitialDelegate {
    // rest of the controller code
    override func viewDidLoad() {
        super.viewDidLoad()
        NotificationCenter.default.addObserver(self, selector: #selector(openInterstitial), name: "playerDied", object: nil)
    }
    func openInterstitial() {
        self.fullScreenAds = CreateAndLoadInterstitial()
    }
    // rest of the controller code
}

SKScene:

class GameScene: SKScene {
    func playedDied() {
        // rest of the method code
        NotificationCenter.default.post(name: "playerDied",
                                    object: nil)
    }
}
