Question

我有两个班级，＆＃39; Unit＆＃39;和＆＃39; Tile＆＃39;。这两个都有一个位置＆＃39;他们这样的课程就像......

class Unit
{
    // add the stats like name , health, speed and strength.
    public Stats stats = new Stats();

    // add the location coordinates
    public Location location = new Location();
}

public class Tile
{
    // add the stats like name , health, speed and strength.
    public Stats stats = new Stats();

    // represents the ability to move out of tile via either {north,east,south,west};
    public List<bool> movementDirections = new List<bool>() { true, true, true, true };

    // represents the Coorinates to access the tile.
    public Location location = new Location();
}

好的，所以......你会注意到我也有“统计数据”和＃39;两个人都上课。两个＆＃39;单位＆＃39;和＆＃39; Tile＆＃39;是新的实例，并且都有新的实例＆＃39;统计数据＆＃39;和＆＃39;位置＆＃39;在他们身上。

我的问题是我有一小段代码可以改变单位的位置，而且行为奇怪。

        static void move(Tile tile,int[] coordsChange,Unit unit)
    {
        // Unit player is defined earlier in the script as a new Unit().
        player.stats.name = "Hendry";// just to check. this doesn't change the tile name
        player.location.x = player.location.x + coordsChange[0]; // these both change the tile location also.
        player.location.y = player.location.y + coordsChange[1];
    }

因为所有内容都是一个新实例并且玩家统计数据的更改并未改变Tile统计数据我不知道为什么但是玩家的位置发生了变化。我也测试了反之亦然，同样的情况发生了......就好像位置类是相关联的，但是尽管没有差别，但统计类没有。

这是BTW课程。

public class Location
{
    private int _x = 0;
    private int _y = 0;

    public int x
    {
        get { return _x; }
        set { _x = value;}
    }

    public int y
    {
        get { return _y;}
        set { _y = value; }
    }
}

public class Stats
{
    public string name = "default";
    public string className = "default";
    public int health = 10;
    public int strength = 5;
    public int defence = 5;
    public int speed = 5;
    public int intelligence = 5;
}

任何想法都会受到赞赏。

封装的重要性：

class Unit
{
    // add the stats like name , health, speed and strength.
    public Stats stats { get; private set; }
    // add the location coordinates
    public Location location { get; private set; }

    public Unit()
    {
        location = new Location();
        stats = new Stats();
    }

}

Tile相同。

我的理论是，在调用move之前，你有代码分配：

player.location = tile.location;

或

tile.location = player.location;

使用私有setter使location属性生成，将导致此类代码出现编译错误。

public class Location
{
    ...
    your code
    ...

    public void Assign(Location aSource)
    {
        x = aSource.x;
        y = aSource.y;
    }
}

tile.location.Assign(player.location);

当我编辑一个实例的变量值时，其他实例也会发生变化
