Question

我一直在按照教程帮助我完成一项我一直在努力的游戏，一切都运行得很顺利，直到我投入这个功能：

func generateCloud(seconds: NSTimeInterval) {
    let x = size.width / 2 * cloudWidth / 2
    let y = CGFloat(arc4random_uniform(UInt32(size.height))) - size.height / 2

    let cloud = MCTCloud(size: CGSizeMake(cloudWidth, cloudHeight))
    cloud.position = CGPointMake(x, y)
    addChild(cloud)
    }

并且AppDelegate.swift中的绿色断点出错，说明了线程1：信号SIGABRT并进一步查看它：

每次我运行游戏时它都会崩溃并将我带回AppDelegate文件中的断点。有点失落和沮丧。感谢您的帮助。

修改这是MCTCloud类：

class MCTCloud: SKShapeNode {
   init(size: CGSize) {
    super.init()
    let path = CGPathCreateWithEllipseInRect(CGRect(x: 0, y: 0, width: size.width, height: size.height), nil)
    self.path = path
    fillColor =
        UIColor.whiteColor()
    startMoving()


    }

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

}
 func startMoving() {
let moveLeft = SKAction.moveByX(-10, y: 0, duration: 1)
runAction(SKAction.repeatActionForever(moveLeft))

}
}

Swift：线程1：在SpriteKit中发出SIGABRT错误信号？
