swift - swift 中的节点没有出现

Question

我试图在我的 Swift 游戏中放置一个节点，但它没有出现。请帮忙!

import SpriteKit
import GameplayKit

class GameScene: SKScene {


    override func didMove(to view: SKView) {

        let levelLabelNode = SKLabelNode(fontNamed: "Arial")
        levelLabelNode.text = "Level"
        levelLabelNode.fontSize = 30
        levelLabelNode.fontColor = SKColor.white
        levelLabelNode.position = CGPoint(x: self.frame.size.width/2, y: self.frame.size.height*0.75)
        self.addChild(levelLabelNode)

here's the code

我复制了相同的代码我也遇到了同样的问题因为字体颜色是白色它与背景颜色相匹配。如果你改变了字体的颜色那么你可以在屏幕上看到标签

let levelLabelNode = SKLabelNode(fontNamed: "Arial")
        levelLabelNode.text = "Level"
        levelLabelNode.fontSize = 30
        levelLabelNode.fontColor = SKColor.green
        levelLabelNode.position = CGPoint(x: self.frame.size.width/2, y: self.frame.size.height*0.75)
        self.addChild(levelLabelNode)
