swift - SKSpriteNode 未更新

Question

我只是想让一个 Sprite 节点在被点击时移动。但似乎场景直到第二次单击另一个 spritenode 时才会更新。

我的错误在哪里？

override init(size: CGSize) {
    super.init(size: size)
    cardLayer = SKNode()
    addChild(cardLayer)
    sprite = SKSpriteNode()
    let cardSize = CGSize(width: 80,height: 100)
    sprite.size = cardSize
    sprite.texture = SKTexture(imageNamed: "1.png")
    sprite.position = CGPoint(x: 200, y: 200)
    sprite.name = "123"
    cardLayer.addChild(sprite)
    sprite1 = SKSpriteNode()
    sprite1.size = cardSize
    sprite1.texture = SKTexture(imageNamed: "1.png")
    sprite1.position = CGPoint(x: 200, y: 300)
    sprite1.name = "123"
    cardLayer.addChild(sprite1)
}




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

    let array = Array(touches)
    let touch = array[0] 
    let location = touch.location(in: self)
    let touchedNode = atPoint(location)
    if let _ = touchedNode.name {
        print("moved")
        touchedNode.position = CGPoint(x: 10, y: 10)
    }
}

这就是我做你想做的事情的方式。

我认为您应该尝试使用节点(位于:)。

这是一个使用中的示例

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


if let touch = touches.first {
//gets location
            let location = touch.location(in: self)
//gets of what nodes are at the location
            let object = nodes(at: location)
// if the there is a node on that location that is the sprite I want
            if object.contains(yourSprite){
//you can put what ever numbers you want to run in there. This simply
// determines the direction of the movement based on a t-Graph
                yourSprite.run(SKAction.moveBy(x: 0, y: -5, duration: 1))
            }
}
