Question

我正在开发一款有角色的游戏。该字符是SKSpriteNode的子类：

class Character: SKSpriteNode {

init() {
    let texture = SKTexture(imageNamed: "character")
    super.init(texture: texture, color: UIColor.white, size: texture.size())
    self.isUserInteractionEnabled = true
    self.zPosition = 10
    self.position = CGPoint(x: 0, y: 0)
    self.name = "character"
}

required init(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}


override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    print("Touch!")

    // Create small +1 sprite
    let plusNode = SKSpriteNode(imageNamed: "plus1Node")
    plusNode.zPosition = 10000 //To make sure its always in front
    plusNode.position = self.position
    self.addChild(plusNode)
}

通过GameScene.swift将角色添加到游戏中：

    func spawnCharacter() {
        //Random postion for the pigs
        let randomX = Functions().randomBetweenNumbers(firstNum: -140, secondNum: 140)
        let randomY = Functions().randomBetweenNumbers(firstNum: -240, secondNum: 240)

        let newCharacter = Character()
        newCharacter = CGPoint(x: randomX, y: randomY)
        gameArea!.addChild(newCharacter)
    }

当玩家点击角色时，会生成一个“ +1”小节点，以显示玩家已触摸角色。我希望将该+1节点生成在角色的顶部，但它的位置很远-就像距离多个点。

如果我将+1代码移动到GameScene（在角色创建并添加到场景之后，位置就定位了）。

我在这里想念什么？

Answer 1

PulzeNode.position = CGpoint.zero

当您将其添加到角色中时，它应该位于父节点的原点
