swift：将 SKShapeNode 转换为 SKSpriteNode -> 无纹理

Question

我试图通过首先将 SKShapeNode 转换为纹理来将 SKShapeNode 转换为 Sprite 节点。然而结果是看不见的精灵。物理体通常在那里，但没有显示图形。我想我尝试转换 SKShapeNode 的方式有问题，但我想不出是什么。你知道出了什么问题吗？感谢所有帮助！

let createdShape = SKShapeNode(path: path)
createdShape.physicsBody = SKPhysicsBody(edgeLoopFromPath: createdShape.path)
createdShape.physicsBody?.categoryBitMask = PhysicsCategory.Shape
createdShape.physicsBody?.contactTestBitMask = PhysicsCategory.None      
createdShape.name = "paintedArea"
createdShape.strokeColor = shapeBorderColor
createdShape.lineWidth = 5.0
createdShape.fillColor = shapeFillColor
createdShape.alpha = 1.0
createdShape.zPosition = shapeZPosition
let texture = view?.textureFromNode(createdShape)
println(texture?.description)                      
let sprite = SKSpriteNode(texture: texture)
sprite.physicsBody = createdShape.physicsBody
sprite.position = createdShape.position
sprite.color = UIColor.blueColor()
self.addChild(sprite)

啊我明白了！我的 Z 轴位置错误！创建的形状位于我的背景图像之上，但新创建的精灵不在。我真是个傻子……
