Question

class GameScene: SKScene {

let balls = [
    SKSpriteNode(imageNamed: "blueball.png"),
    SKSpriteNode(imageNamed: "greenball.png"),
    SKSpriteNode(imageNamed: "realredball.png"),
]

override func didMove(to view: SKView) {

    spawnBalls()

}

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        for ball in balls{
            ball.physicsBody = SKPhysicsBody()
            ball.physicsBody?.affectedByGravity = true


        }
}

func spawnBalls() {
   for ball in balls{
    balls[Int(arc4random_uniform(UInt32(balls.count)))]

    ball.position = CGPoint(x: 0, y: 250)
    ball.size = CGSize(width: 70, height: 70)
        self.addChild(ball)
    }
}

}

每次我的应用加载红球产生，但它应该随机产生红色，蓝色或绿色球。起初，它实际上工作，并会随机产生红色，绿色或蓝色，我不知道我是否意外改变了一些东西，但在最近两天它刚刚产生红色的那个。如果有人可以帮助那将是伟大的。感谢。

Answer 1

你实际上并没有在spawnBalls中对随机球做任何事情。试试这个

随机产生节点
