检查随机操作的结果？

Question

var colorize1 = SKAction.colorizeWithColor(.redColor(), colorBlendFactor: 1.0, duration: 0.3)

        var colorize2 = SKAction.colorizeWithColor(.greenColor(), colorBlendFactor: 1.0, duration: 0.3)

        var colorize3 = SKAction.colorizeWithColor(.blueColor(), colorBlendFactor: 1.0, duration: 0.3)

        var actions = [colorize1, colorize2, colorize3]

        var randomIndex = Int(arc4random_uniform(3))

        var action = actions[randomIndex]

        let seconds = 0.14
        let delay = seconds * Double(NSEC_PER_SEC)  // nanoseconds per seconds
        let dispatchTime = dispatch_time(DISPATCH_TIME_NOW, Int64(delay))

        dispatch_after(dispatchTime, dispatch_get_main_queue(), {


            self.Ball.runAction(action)


        })

    }

因此，此代码将我的球着色为红色、绿色或蓝色。当我的游戏是运行时，有没有办法检查它选择了哪种颜色？它不只是选择一个然后就完成了，我的球的颜色每隔几秒钟就会改变一次。我如何构造一个 if 语句，例如："If the random color picked by my action is red then print("hey") 或类似的语句？

编辑我是 swift 和 xCode 的新手，所以我可能需要更深入的帮助。

Answer 1

您只需打开 randomIndex:

switch randomIndex  {
case 0:
    print("colorize1")
case 1:
    print("colorize2")
case 2:
    print("colorize3")
}
