Question

我创建了一个球节点，并应用了3d模型中的纹理图像。我总共捕获了6张图像，其中3张图像（具有120度）用于绕x轴滚动，其余3张图像用于绕y轴滚动。我想要精灵套件使用下面的代码来模拟它。当我施加脉冲时，它开始滑动而不是滚动，并且当它碰撞到侧面时，它开始旋转但又不滚动。通常，根据对球的冲动，它有时应转动并滚动在一起。我想获得结果的例子是“ 8球池游戏”球的效果。

var ball = SKSpriteNode()
var textureAtlas = SKTextureAtlas()
var textureArray = [SKTexture]()

override func didMove(to view: SKView) {

    textureAtlas = SKTextureAtlas(named: "white")
    for i in 0... textureAtlas.textureNames.count {
        let name = "ball_\(i).png"
        textureArray.append(SKTexture(imageNamed: name))
    }

    ball = SKSpriteNode(imageNamed: textureAtlas.textureNames[0])
    ball.size = CGSize(width: ballRadius*2, height: ballRadius*2)
    ball.position = CGPoint(x: -ballRadius/2-20, y: -ballRadius-20)
    ball.zPosition = 0

    ball.physicsBody = SKPhysicsBody(circleOfRadius: ballRadius)
    ball.physicsBody?.isDynamic = true
    ball.physicsBody?.restitution = 0.3
    ball.physicsBody?.linearDamping = 0
    ball.physicsBody?.allowsRotation = true

    addChild(ball)}

您需要施加角度冲动才能使其旋转

var getRectArea = function(width, height) { return width * height; }; console.log("Area of Rectangle: " + getRectArea(3,4)); // This should return the following result in the console: // Area of Rectangle: 12
