C# Nested classes | 易学教程

问题

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
    {

    }
}

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.

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

回答1:

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
{

}

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

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

Then MyPlayer should have a reference to a Movement instance.

public class MyPlayer : Player
{
    public static Movement movement = new Movement();
    ...
}
