將列表的一部分復制到另一個列表

Question

我目前正在嘗試將一個列表的各個部分復制到另一列表中，但現在很難。

我對使用列表非常陌生。

我已經創建了一個構造函數。

然后，我創建了一個列表，其中包含我需要的所有項目。 我想從第一個列表中復制一個隨機片段到第二個列表中。 然后，我想從原始列表中刪除我復制的作品。

這是我當前的代碼。

我的構造函數代碼

using UnityEngine;
using System.Collections;

public class Character_Setup {

    // Declare Attributes
    public int Agility = 1;
    public int Stamina = 1;
    public int Strength = 1;
    public int Critical_Hit = 1;
    public string Weapon ="";


    // Declare Stats
    public int Speed = 1;
    public int Health= 2;
    public int Damage = 3;
    public int Acuity = 4;

    public Character_Setup(string _name)
    {
        Weapon = _name;
        Speed = Agility * Random.Range (1,10);
        Health = Stamina * Random.Range (1,10);
        Damage = Strength * Random.Range (1,10);
        Critical_Hit = Acuity * Random.Range (1,10);

    }

}

這是我當前嘗試將代碼從一個組復制到另一個組的嘗試。

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class Game_Play : MonoBehaviour {

    public int Num_Players = 11;
    public int Players = 1;




    // Use this for initialization
    void Start () {

        //Create a list
        // Using Character_Setup
        //add 10 characters to list

        List <Character_Setup> Characters = new List<Character_Setup> ();

        Characters.Add (new Character_Setup ("Flamethrower"));
        Characters.Add (new Character_Setup ("Shotgun"));
        Characters.Add (new Character_Setup ("Rifle"));
        Characters.Add (new Character_Setup ("Pistol"));
        Characters.Add (new Character_Setup ("Machine Gun"));
        Characters.Add (new Character_Setup ("Grenade Launcher"));
        Characters.Add (new Character_Setup ("Knife"));
        Characters.Add (new Character_Setup ("Rocket Launcher"));
        Characters.Add (new Character_Setup ("Throwing Star"));
        Characters.Add (new Character_Setup ("Sling Shot"));



        /*foreach (Character_Setup character in Characters) {
            print (character.Weapon);
        }*/

        // Create 2 teams Off 3 Players

        // Team 1
        // Create Blue Team
        List<Character_Setup> Blue_Team = new List<Character_Setup> ();
        Blue_Team.AddRange (Characters);

        foreach (Character_Setup character in Blue_Team)
        {
            print (character.Weapon);
        }


        // Team 2
        //Create Red Team
        //List<Character_Setup> Red_Team = new List<Character_Setup> ();
        //Red_Team.AddRange (Characters);

    }


    // Update is called once per frame
    void Update () {

    }
}

當前，此代碼將所有內容復制過來。 我希望能夠在Characters中選擇某些內容並將其復制到Blue_Team。

我已經上網，現在迷路了。

我該怎么做，只復制字符列表中的一部分，然后將其刪除？

Answer 1

如果我理解您的要求，此代碼將根據Character.Weapon值將單個Character復制到Blue_Team ，但是可以將其更改為所需的任何值。

Character selectedChar = Characters.Where(objChar => objChar.Weapon == "Knife");

Blue_Team.Add(selectedChar);

如果要幾個對象，則可以使用以下代碼返回列表：

List<Character> selectedCharList = Characters.Where(objChar => objChar.Weapon == "Knife").ToList();

Blue_Team.AddRange(selectedCharList);

這種方法使用System.Linq ，在使用列表時非常方便。 我用它所有的時間。

首先感謝您的回答。 他們沒有給我直接的答案，但是他們的確帶我走了正確的道路，這使我得到了我的答案。 這正是我所需要的。

我還學會了用代碼和注釋更加清晰。

這是我為實現所需代碼而編寫的代碼。

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class Game_Play : MonoBehaviour {

    public int Num_Players = 11;
    public int Players = 1;




    // Use this for initialization
    void Start () {

        //Section 1
        //Create a list
        // Using Character_Setup
        //add 10 characters to list

        List <Character_Setup> Characters = new List<Character_Setup> ();

        Characters.Add (new Character_Setup ("Flamethrower"));
        Characters.Add (new Character_Setup ("Shotgun"));
        Characters.Add (new Character_Setup ("Rifle"));
        Characters.Add (new Character_Setup ("Pistol"));
        Characters.Add (new Character_Setup ("Machine Gun"));
        Characters.Add (new Character_Setup ("Grenade Launcher"));
        Characters.Add (new Character_Setup ("Knife"));
        Characters.Add (new Character_Setup ("Rocket Launcher"));
        Characters.Add (new Character_Setup ("Throwing Star"));
        Characters.Add (new Character_Setup ("Sling Shot"));

        foreach (Character_Setup character in Characters) {
            print (character.Weapon);
        }

        //Section 2
        // Create 2 teams Off 3 Players

        // Team 1
        //Create Blue Team
        //use loop to fill team
        //Create Variable to hold selection number
        //Add to team
        //Remove from Characters availble
        List<Character_Setup> Blue_Team = new List<Character_Setup> ();
        while (Blue_Team.Count < 3)
        {
            Character_Setup PlayerSelection = Characters [UnityEngine.Random.Range(0, Characters.Count)];
            Blue_Team.Add (PlayerSelection);
            Characters.Remove(PlayerSelection);
        }

        foreach (Character_Setup character in Blue_Team)
        {
            print (character.Weapon);
        }

        // Team 2
        //Create Red Team
        List<Character_Setup> Red_Team = new List<Character_Setup> ();
        while (Red_Team.Count < 3)
        {
            Character_Setup PlayerSelection = Characters [UnityEngine.Random.Range (0, Characters.Count)];
            Red_Team.Add (PlayerSelection);
            Characters.Remove(PlayerSelection);
        }

        foreach (Character_Setup character in Red_Team)
        {
            print (character.Weapon);
        }

    }

一種方法是在Character_Setup類中具有Team屬性，然后您可以通過該屬性選擇誰進入列表。 應該有一個枚舉。.但是要開始，只需添加public int Team = 0 ，然后在構造函數中允許將Team = 1分配給“ blue team”，將Team = 2分配給“ red team”（team 0是“ no team” ”，由您決定是否支持，如果不允許，則只允許1和2，而不是0、1、2）。

然后，您可以做Blue_Team.AddRange(Characters.Where(c => c.Team == 1)); 。

沒有LINQ的另一種方法是這樣的：

foreach (var charact in Characters)
{
    if (charact.Team == 1)
    {
        Blue_Team.Add(charact);
    }

    if (charact.Team == 2)
    {
        Red_Team.Add(charact);
    }    
}
