ios - 线程 1 : Signal SIGABRT sprite kit

Question

我试图在 x 方向上生成多个节点，然后将它们作为一个单元在 y 方向上生成。我在 x 方向生成了节点。我创建了一个包含在 x 方向移动的节点的父节点，并尝试在 y 方向移动父节点。我在 AppDelegate 中不断收到“线程 1:信号 SIGABRT”。这是正确的方法吗？

这是我到目前为止所拥有的:

抱歉代码太长。谢谢，

尝试此代码，看看它是否适合您。

spawnClouds()

func createCloud() -> SKSpriteNode {

    let i = arc4random_uniform(2) + 1
    let randomPos = arc4random_uniform(200)

    let cloud = SKSpriteNode(imageNamed: "cloud\(i)")
    cloud.position = CGPointMake(self.size.width + cloud.size.width / 2 - CGFloat(50 + randomPos) , self.size.height * 0.65 - CGFloat(50 + randomPos))
    cloud.zPosition = 4000
    let radius = CGFloat(cloud.size.width / 2)
    cloud.physicsBody = SKPhysicsBody(circleOfRadius: radius)
    cloud.physicsBody?.categoryBitMask = PhysicsCategory.Cloud
    cloud.physicsBody?.collisionBitMask = PhysicsCategory.Hero
    cloud.physicsBody?.contactTestBitMask = PhysicsCategory.Hero
    cloud.physicsBody?.dynamic = false
    cloud.physicsBody?.affectedByGravity = false
    addChild(cloud)

    return cloud
}

func spawnClouds() {

    for _ in 0..<5 {

        let addAndMoveCloud = SKAction.runBlock({
            let randomDuration = CGFloat(arc4random_uniform(2)) / 5 + 10
            let cloud = self.createCloud()
            cloud.runAction(SKAction.moveTo(CGPoint(x: -cloud.size.width, y: self.size.height + cloud.size.height), duration: NSTimeInterval(randomDuration)), completion: { cloud.removeFromParent()
            })
        })

        let delay = SKAction.waitForDuration(2)
        let spawnClouds = SKAction.sequence([addAndMoveCloud, delay])

        runAction(SKAction.repeatActionForever(spawnClouds))
    }
