SpriteKit SKTextures

Question

        for building in self.buildingArray {
        if building.contains(location) {
            upgradeArray.removeAll()
            upgradeArray.append(building)
            for tower in self.upgradeArray {
                print(tower.position.x)
                let buildingExample = SKSpriteNode()
                buildingExample.texture = tower.texture
                buildingExample.position.y = spikeTowerOption.position.y
                buildingExample.position.x = 0
                buildingExample.zPosition = 20
                buildingExample.setScale(frame.size.height/3700)
                self.addChild(buildingExample)
            }
        }
    }

这里的问题是关于纹理的。我不知道如何正确地获取塔的纹理并使 buildingExample 具有相同的纹理。目前，建筑示例未在屏幕上显示。

替换：

            let buildingExample = SKSpriteNode()
            buildingExample.texture = tower.texture

对于：

            let buildingExample = SKSpriteNode(texture: tower.texture)
