C#嵌套类 [英] C# Nested classes

问题描述

我正在尝试在主类中创建一些嵌套类.

I am trying to create a few nested classes within my main class.

public class MyPlayer : Player
{

    public bool TargetEnemy()
    {
        return true;

    }

    public class Movement
    {
        public uint aInt = 1;

        public TurnLeft()
        {

        }
    }

    public class ActionBar
    {

    }
}

我有许多不同的类，因此我可以通过代码访问MyPlayer类，而无需将其传递给所有这些类，我只是创建了一个静态类来为其保存变量.我可以使用Main.Units.MyPlayer.Movement访问MyPlayer-> Movement，但这未链接到我在静态类中定义的MyPlayer实例.

I have many different classes so that I would be able to access the MyPlayer class through out the code without passing it to all them I just created a static class that holds the variable for it. I am able to access the MyPlayer->Movement using Main.Units.MyPlayer.Movement but this is not linked to the MyPlayer instance I have defined in the static class.

例如，我希望能够执行MyPlayer-> Movement-> TurnLeft().我将如何实现呢?感谢您的回答.

I want to be able to do MyPlayer->Movement->TurnLeft() for example. How would I achieve this? Thanks for your answers.

推荐答案

您可能会误认为类嵌套和类组合的概念.为了在Player类中包含一个Movement实例，可以定义一个私有字段movement和一个公共属性Movement来访问它.

You might be mistaking the concept of class nesting with class composition. In order to have a Movement instance within your Player class, you can define a private field movement and a public property Movement to access it.

public class Player
{        
    public bool TargetEnemy()
    {
        return true;            
    }

    private Movement movement = new Movement();

    public Movement Movement
    {
        get { return movement; }
        set { movement = value; }
    }
}

public class Movement
{
    public uint aInt = 1;

    public TurnLeft()
    {

    }
}

public class ActionBar
{

}

然后，您可以创建Player类的实例并访问其包含的Movement:

Then, you may create an instance of your Player class and access its contained Movement:

Player myPlayer = new Player();
myPlayer.Movement.TurnLeft();
