有没有一种方法可以将四个switchLane功能变成一个功能，并随机选择它切换到哪个通道？

如何解决有没有一种方法可以将四个switchLane功能变成一个功能，并随机选择它切换到哪个通道？

我正在做一个汽车游戏，敌人有行为要移动到道路上的特定点，我已经有4个点，但是我不知道如何随机化敌人预制件向何处移动，我必须更改它现在手动。我将非常感谢您的帮助，并已经感谢您。我是编码的初学者，请放轻松;）

    // Start is called before the first frame update

    // Update is called once per frame

解决方法

您可以在C＃中使用Random类来生成1到4之间的随机值，switch语句可以基于如下所示的随机值调用任何方法

var lane = new Random().Next(1,5);
switch (lane)
{
    case 1:
       switchLane1();
       break;
    case 2:
       switchLane2();
       break;
    case 3:
       switchLane3();
       break;
    case 4:
       switchLane4();
       break;
    default:
       break;
}

,

这是一个小小的独立程序，可以帮助您了解如何实现想要实现的目标：

using System;

class Program
{
    static void Main()
    {
        // Here are all the lanes in an array
        var lanes = new float[]{7.25f,2.45f,2.4f,7.3f};
        // Here is a random number generator
        var rand = new Random();
        
        // This will call 'switchLane' with one lane picked at random
        switchLane(lanes[rand.Next(0,lanes.Length)]);
    }
    
    static void switchLane(float lane)
    {
        // This displays the lane,change to whatever you want to do with it
        Console.WriteLine(lane);
    }
}

,

由于“车道”在您的程序中是如此重要，因此我将为其提供自己的类。可能看起来像这样：

class Lane
{
    public float Position { get; }

    public Lane(float position) => this.Position = position;
    
    public MoveInto(GameObject objectToMove)
    {
        Vector3 targetPos1 = new Vector3(this.Position,0);
        objectToMove.Position += (targetPos1 * speed * Time.deltaTime);

        if (objectToMove.Position <= this.Position)
        {
            //etc....
        }
    }
}

然后在您的EnemyScript类中，保留以下列表：

class EnemyScript : MonoBehavior
{
    private Lane[] lanes = new Lane[]  
    {
        new Lane(7.25f),new Lane(2.45f),new Lane(2.4f),new Lane(7.3f)
    };

然后切换到其中一条车道，只需执行以下操作：

lanes[laneNumber - 1].MoveInto(player);
