Question

第一个原始代码是使用enum和switch，case，state的4个方向点，每个路点都有自己的功能。这工作正常。但现在我添加了wayPoints的变量名GameObject数组。

相反，我想为每个路点添加一个新函数，使其成为一个函数。例如，假设我有30个立方体，我将它们添加到wayPoints数组中，现在我希望角色在30个立方体之间作为路点行走。所以我添加了一个新的State并将其称为WayPoints。我还添加了一个新功能，并将其命名为WayPoints()

现在我不确定如何从这里继续。我仍然希望将enum想法与wayPoints数组一起使用，但不确定我添加的案例是否正确以及如何在WayPoints()函数中执行此操作。

    public enum State
    {
        Idle,
        Way1,
        Way2,
        Way3,
        Way4,
        WayPoints
    }

        myTransform = transform;
    }
    // Use this for initialization
    void Start()

        Debug.Log("Scripts Strart");
        state = State.Idle;
    }

    // Update is called once per frame
    void Update()
    {
        Debug.Log("Update");
        switch (state)
        {
            case State.Idle:

这有一个很好实现的航路点系统，您可能需要查看：https://unity3d.com/learn/tutorials/topics/scripting/using-interfaces-make-state-machine-ai

你应该制作一个简单的公共GameObject []航点，并在那里拖放你想要的航点，并使用索引来循环它们。这可以替换第一行代码，因此您可以使用相同的方法。

我如何为每个方向点制作多个路径点而不是多个功能点？
