Question

我正在尝试创建放入数组的节点，然后将它们与物理实体一起添加到场景中。

以下是创建初始精灵的代码：

            let name = createTarget()
            let targetNode = SKSpriteNode(imageNamed: name)
            targetNode.name = name

            chickenNodes.append(targetNode)
            targetNode.position = generateRandomLocation()

            let range = SKRange(lowerLimit: targetNode.position.y, upperLimit: targetNode.position.y)
            let lockToCenter = SKConstraint.positionY(range)
            targetNode.constraints = [lockToCenter]

            if movingItems { animateTargets(targetNode) }

一旦所有这些节点都在数组中，我将它们在didMove中添加到场景中的背景节点fgNode，如下所示：

for chicken in chickenNodes {
        let texture = SKTexture(imageNamed: chicken.name!)
        chicken.physicsBody = SKPhysicsBody(texture: texture, size: texture.size())
        chicken.physicsBody?.isDynamic = true
        chicken.physicsBody?.affectedByGravity = true
        chicken.physicsBody?.allowsRotation = false
        chicken.physicsBody?.linearDamping = 0.0
        chicken.physicsBody?.restitution = 1.0
        chicken.physicsBody?.friction = 0.0
        fgNode.addChild(chicken)
    }

当我通过场景观察物理时，物理实体不断从精灵中掉落（好像它们对场景中的重力作出反应）;精灵只是被锁定在原处。我如何确保physicsBody坚持精灵？
