Question

在我的GameScene.swift文件中，存在导致构建失败的错误。

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
    /* Called when a touch begins */

    for touch: AnyObject in touches {
        let location = touch.locationInNode(self)

        let sprite = SKSpriteNode(imageNamed:"Spaceship")

        sprite.xScale = 0.5
        sprite.yScale = 0.5
        sprite.position = location

        let action = SKAction.rotateByAngle(CGFloat(M_PI), duration:1)

        sprite.runAction(SKAction.repeatActionForever(action))

        self.addChild(sprite)
    }
}

override func update(currentTime: CFTimeInterval) {
    /* Called before each frame is rendered */
}

我被告知'覆盖只能在班级成员上指定。

我该如何解决这个问题？

这就是全部：

class GameScene: SKScene {

override func didMoveToView(view: SKView) {
    /* Setup your scene here */

    var swipes = SPSwipes()

    if swipes.no_of_swipes == 5 {
        var array = Array<UInt32>(count: 5, repeatedValue: 0)
        for i in 0 ..< 5 {
            array[i] = arc4random_uniform(100)}
        }

    if swipes.no_of_swipes == 10 {
        var array = Array<UInt32>(count: 10, repeatedValue: 0)
        for i in 0 ..< 10 {
            array[i] = arc4random_uniform(100)}
    }

    if swipes.no_of_swipes == 25 {
        var array = Array<UInt32>(count: 25, repeatedValue: 0)
        for i in 0 ..< 25 {
            array[i] = arc4random_uniform(100)}
    }

 func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
    /* Called when a touch begins */

    for touch: AnyObject in touches {
        let location = touch.locationInNode(self)

        let sprite = SKSpriteNode(imageNamed:"Spaceship")

        sprite.xScale = 0.5
        sprite.yScale = 0.5
        sprite.position = location

        let action = SKAction.rotateByAngle(CGFloat(M_PI), duration:1)

        sprite.runAction(SKAction.repeatActionForever(action))

        self.addChild(sprite)
    }
}

func update(currentTime: CFTimeInterval) {
    /* Called before each frame is rendered */
}
}

评论部分提到的底部还有语法错误。

Answer 1

在行

之前添加“}”

func touchesBegan(touches: NSSet, withEvent event: UIEvent) {

Answer 2

有2个答案，一个是你在某个地方使用了覆盖，否则你会丢失一个braket或一个圆形的braket

Swift：只能在类成员上指定覆盖
