代表名单及调用

我正在 ASP.NET 中创建一个较小的 RPG 游戏。在这个游戏中，我有一个项目架构，其中每个项目都有一些方法。例如，所有项目都应该共享“Drop”、“Examine”和“Use”等方法。有些项目必须使用“操作”、“计算”等方法进行扩展。

到目前为止，我已经创建了以下对象 GameActionList：

public delegate void MyDelegate();

public class GameActionList
{
    public List<MyDelegate> Items = new List<MyDelegate>();

    public void Add(MyDelegate del)
    {
        Items.Add(del);
    }

    public void CallDelegates()
    {
        foreach (MyDelegate myDelegate in Items)
        {
            myDelegate();
        }
    }
}

我有一个 BaseItem 类，其中包含此 GameActionList。 BaseItem 类中 this 的 get 属性如下：

    public GameActionList Actions 
    { 
        get
        {
            GameActionList actions = new GameActionList();
            actions.Add(this.Drop);
            actions.Add(this.Examine);
            return actions;
        }
    }

这很好，但是...我有一些问题！

我的问题

我需要一种更通用的 GameActionList。我不仅需要一个包含 void 的列表，还需要一个包含函数的列表。此外，我需要带参数和不带参数的方法。

例如： Drop 方法需要一个 Player 对象，这样他就可以 Drop 项目。 Examine 方法需要返回描述该项目的字符串。

另外，我需要一些在初始化 GameActionList 时不知道的数据：当我调用该方法时，我首先知道这些数据...

所以我有两个问题：

如何扩展 GameActionList，以便它可以包含一个列表空隙和函数，而且它们都可以有参数或没有参数..（它甚至有意义吗？）
我如何在循环的稍后阶段向方法提供一些数据，例如调用时？

另外......这可能是一种非常愚蠢的方法，所以如果你有一些更优雅的解决方案......我非常愿意听到它！

多谢...！拉尔斯

原文

I am creating a smaller RPG game in ASP.NET. In this game I have an items architecture, where each item has some methods. For instance, all items should share a method like "Drop", "Examine" and "Use". Some items will have to be extended with methods like "Operate", "Calculate" and such.

So far, I have created the following object GameActionList:

public delegate void MyDelegate();

public class GameActionList
{
    public List<MyDelegate> Items = new List<MyDelegate>();

    public void Add(MyDelegate del)
    {
        Items.Add(del);
    }

    public void CallDelegates()
    {
        foreach (MyDelegate myDelegate in Items)
        {
            myDelegate();
        }
    }
}

I have a BaseItem class, which has this GameActionList. The get property of this in the BaseItem class is like this:

    public GameActionList Actions 
    { 
        get
        {
            GameActionList actions = new GameActionList();
            actions.Add(this.Drop);
            actions.Add(this.Examine);
            return actions;
        }
    }

This is fine, BUT... I have some problems!

My problem

I need a way more generic GameActionList. I need to have a list of not only voids, but also functions.. Also, I need both methods with parameters and without parameters.

For instance: The Drop method will need a Player object, so he can Drop the item. The Examine method will need to return a string descriping the item.

Also, I need some data which I don't know when I Initialize the GameActionList: I first know these data when I invoke the method...

So I have two questions:

How do you extend the GameActionList, so it can contain a list of both voids and functions andalso these both can have parameters or not.. (AND DOES IT EVEN MAKE SENSE??)
How can I give some data to the method later in the cycle, like when invoking?

Also... This might be a very stupid way to do it, so if you have some way more elegant solution.. I'm more than ready to hear it!

Thanks a lot...!
