试图弄清楚如何在 Cocossharp (BouncyGame) 中暂停和恢复

Question

所以我正在玩 BouncyGame。我做到了，当你开始游戏时，你需要按下屏幕才能开始。每当你玩新一轮时，我也想实施这一点。我试图在我的代码底部重用这个 att，但它变得非常迟钝。

// Register for touch events
        var touchListener = new CCEventListenerTouchAllAtOnce();
        touchListener.OnTouchesEnded = OnTouchesEnded;

        touchListener.OnTouchesMoved = OnTouchesEnded;
        AddEventListener(touchListener, this);


    }

    void OnTouchesEnded(List<CCTouch> touches, CCEvent touchEvent)
    {
        if (touches.Count > 0)
        { 
            Schedule(RunGameLogic);
            scoreLabel.Text = "Score: 0";
            paddleSprite.RunAction(new CCMoveTo(.1f, new CCPoint(touches[0].Location.X, paddleSprite.PositionY)));
        }
    }

我不知道该怎么做，试了 2 小时，结果为 0。欢迎提出任何建议。

这是完整的代码。

    CCLabel scoreLabel;
    CCSprite paddleSprite, ballSprite;

    public IntroLayer() : base(CCColor4B.Black)
    {

        // create and initialize a Label
        scoreLabel = new CCLabel("Tap to GO!", "Arial", 80, CCLabelFormat.SystemFont);

        // add the label as a child to this Layer
        scoreLabel.PositionX = 50;
        scoreLabel.PositionY = 1000;
        scoreLabel.AnchorPoint = CCPoint.AnchorUpperLeft;
        AddChild(scoreLabel);

        paddleSprite = new CCSprite("paddle.png");
        AddChild(paddleSprite);

    int score = 0;

    void RunGameLogic(float frameTimeInSeconds)
    {
        // This is a linear approximation, so not 100% accurate
        ballYVelocity += frameTimeInSeconds * -gravity;
        ballSprite.PositionX += ballXVelocity * frameTimeInSeconds;
        ballSprite.PositionY += ballYVelocity * frameTimeInSeconds;

        bool overlap = ballSprite.BoundingBoxTransformedToParent.IntersectsRect(paddleSprite.BoundingBoxTransformedToParent);
        bool movingDown = ballYVelocity < 0;

            ballXVelocity = CCRandom.GetRandomFloat(minXVelocity, maxXVelocity);

            score++;
            scoreLabel.Text = "Score: "  + score;
        }

        float ballRight = ballSprite.BoundingBoxTransformedToParent.MaxX;
        float ballLeft = ballSprite.BoundingBoxTransformedToParent.MinX;

        float screenRight = VisibleBoundsWorldspace.MaxX;
        float screenLeft = VisibleBoundsWorldspace.MinX;

        bool shouldReflectXVelocity =
            (ballRight > screenRight && ballXVelocity > 0) ||
            (ballLeft < screenLeft && ballXVelocity < 0);
        if (shouldReflectXVelocity)
        {
            ballXVelocity *= -1;
        }
        if (ballSprite.PositionY < VisibleBoundsWorldspace.MinY)
        {
            ballSprite.PositionX = 320;
            ballSprite.PositionY = 640;

            ballXVelocity = 0;
            ballYVelocity = 0;
            ballYVelocity *= -1;
            scoreLabel.Text = "Score: 0";
            score = 0;
        }
    }
}
}

提前致谢！

想通了！ Cocossharp 中内置了一个 "Unschedule" 方法。参考https://developer.xamarin.com/api/namespace/CocosSharp/

我刚刚添加了

Unschedule(RunGameLogic);

在我的 RunGameLogic 方法的最后

if (ballSprite.PositionY < VisibleBoundsWorldspace.MinY)

因此，一旦 ballSprite 超出范围，它将取消我在 OntouchesEnded 方法中安排的计划。这意味着代码返回到监听触摸。

可能有一些错误，但这是我能想到的最好的方法，而且有效！
