Question

我在场景中有2个物理实体。其中一个机体是一个直接向下（由于重力）下降的盒子，另一个是可以在盒子上站立，跑步或跳跃的玩家。

目前，当玩家与掉落的盒子发生碰撞时，它们互相反弹，但是，我不希望他们这样做，我希望盒子和玩家不会相互影响。身体动作，但只是为了让玩家能够站立，跑动和跳跃，而他在盒子上。

这是两个精灵的代码：

func setUpPlayer() {
        player.physicsBody = SKPhysicsBody(rectangleOfSize: player.size)
        player.physicsBody?.mass = 1
        player.physicsBody?.restitution = 0
        player.xScale = 0.5
        player.yScale = 0.5
        player.position = CGPoint(x: 600, y: 800)
        addChild(player)
    }

func addSquare() {
        let squareNode = SKSpriteNode(imageNamed: "fblogo.png")

        squareNode.physicsBody = SKPhysicsBody(rectangleOfSize: squareNode.size)
        squareNode.physicsBody?.mass = 1
        squareNode.physicsBody?.restitution = 0.2
        squareNode.physicsBody?.linearDamping = 0
        squareNode.physicsBody?.angularDamping = 0
        squareNode.physicsBody?.dynamic = true
        squareNode.xScale = 0.5
        squareNode.yScale = 0.5
        squareNode.position = CGPoint(x: 500, y: 700)
        self.addChild(squareNode)
        squaresArray.addObject(squareNode)
    }

尝试将他们的physicsBody.collisionBitMask设置为零。也许你只能做0：

func setUpPlayer() {
        player.physicsBody = SKPhysicsBody(rectangleOfSize: player.size)
        player.physicsBody?.mass = 1
        player.physicsBody?.restitution = 0
        player.xScale = 0.5
        player.yScale = 0.5
        player.position = CGPoint(x: 600, y: 800)
        addChild(player)
    }

func addSquare() {
        let squareNode = SKSpriteNode(imageNamed: "fblogo.png")

        squareNode.physicsBody = SKPhysicsBody(rectangleOfSize: squareNode.size)
        squareNode.physicsBody?.mass = 1
        squareNode.physicsBody?.restitution = 0.2
        squareNode.physicsBody?.linearDamping = 0
        squareNode.physicsBody?.angularDamping = 0
        squareNode.physicsBody?.dynamic = true
        squareNode.physicsBody?.collisionBitMask = 0
        squareNode.xScale = 0.5
        squareNode.yScale = 0.5
        squareNode.position = CGPoint(x: 500, y: 700)
        self.addChild(squareNode)
        squaresArray.addObject(squareNode)
    }

这可能不是完全你需要什么，因为我没有在发布之前把它放到Xcode中，以检查它是否有效。但是在对象上设置collisionBitMask意味着它只与传入UInt或变量的BitMask对象“撞到”或“碰撞”。这样，它仍然是动态的，但不受碰撞的物理影响。
