Question

我有9个SKSpritenode，我想检测与另一个SKSpritenode的联系。我将ContactTestBitMask设置为联系，但是从未调用过did开始联系人中的代码。

 for i in (0...8){


        squares[i].node.position = positions[i]
        squares[i].node.physicsBody?.categoryBitMask = physics[i]
        squares[i].node.physicsBody = SKPhysicsBody(rectangleOf: squares[i].node.size )
        squares[i].node.physicsBody?.affectedByGravity = false
        squares[i].node.physicsBody?.isDynamic = false
        squares[i].node.physicsBody?.contactTestBitMask = PhysicsCategory.Circle
        squares[i].node.physicsBody?.collisionBitMask = 0
        squares[i].node.color = squares[i].startColor
        squares[i].node.colorBlendFactor = 1.0
        squares[i].node.size = CGSize(width: squareUnit, height: squareUnit)



    }

Answer 1

解决您的问题的方法是移动此行（在1234 Brake 66.78 Warehouse A 4方法中）：

createSquares()

在物理实体初始化之后

，这里发生：

squares[i].node.physicsBody?.categoryBitMask = physics[i]

并处理这样的联系人：

squares[i].node.physicsBody = SKPhysicsBody(rectangleOf: squares[i].node.size )

SKSpritenodes没有创建联系人
