多个SKSpriteNode？

Question

这就是我目前所做的。

    patch1.position = CGPointMake(CGRectGetMidX(self.frame) - 80, CGRectGetMidY(self.frame) + 205)
    patch1.yScale = 0.75
    patch1.xScale = 0.75
    self.addChild(patch1)

    percent1.position = CGPointMake(CGRectGetMidX(self.frame) - 80, CGRectGetMidY(self.frame) + 125)
    percent1.xScale = 0.5
    percent1.yScale = 0.5
    self.addChild(percent1)

    patch2.position = CGPointMake(CGRectGetMidX(self.frame) - 80, CGRectGetMidY(self.frame) + 55)
    patch2.yScale = 0.75
    patch2.xScale = 0.75
    self.addChild(patch2)

    percent2.position = CGPointMake(CGRectGetMidX(self.frame) - 80, CGRectGetMidY(self.frame) - 25)
    percent2.xScale = 0.5
    percent2.yScale = 0.5
    self.addChild(percent2)

除了我每个人都有8个。我只是想，在说了这么多，做了这么多之后，经常更新这些将是一件痛苦的事情。有没有更好的方法来设置它们，以便更容易/更高效地更新它们？最后，我将添加一个函数，当点击percent++时

我不确定这些精灵节点在你的应用程序中做什么，但假设它们都在做类似的事情，你可以创建一个SKNode的子类，并在这个子类中声明它们。

class MySubclass: SKNode {
    // Declare variables here.... initialize them in init().... ect.
    let node1 = SKSpriteNode()
    let node2 = SKSpriteNode()

    override init(){
        // DON'T FORGET TO ADD YOUR NODES AS CHILDREN!!
        self.addChild(node1)
        self.addChild(node2)
    }
}

然后在你的主视图中，你可以这样做：

let myNodeSubClass = MySubclass() //Assuming your subclass init doesn't have any parameters

override init(size: CGSize){
    super.init(size)
    myNodesubClass.position = CGPointMake(200, 200) //This will set the position of all the children of your sub class
}

你可以使用方法。

func createSomething(yPosition: CGFloat,xScale: CGFloat, yScale: CGFloat) {

    let percent = SKSpriteNode(imageNamed:"Something")
    percent.position = CGPointMake(self.frame.size.width / 2 - 80, self.frame.size.height / 2 + yPosition )
    percent.xScale = xScale
    percent.yScale = yScale
    self.addChild(percent)
}

您可以像这样添加对象：

   self.createSomething(205, xScale: 0.75, yScale: 0.75);

   self.createSomething(125, xScale: 0.5, yScale: 0.5);

   self.createSomething(55, xScale: 0.75, yScale: 0.75);

   self.createSomething(-25, xScale: 0.5, yScale: 0.5);
