之前开内部培训，说到实时web应用这一块讲到了SignalR，我说找时间用它做个游戏玩玩，后面时间紧张就一直没安排。这两天闲了又想起这个事，考虑后决定用2天时间写个斗D主，安排了前端同学写客户端，我写游戏逻辑和服务。
这个项目难度并不高，但是游戏逻辑还是挺绕的，联调过程中也发现解决了很多小问题。来园子里整理一篇文章，记录一下。
基础的介绍就免了，毕竟官网跟着走两圈啥都懂了。没基础的可以戳这里，是我之前写的一篇SignalR基础介绍，带有一个极简聊天室。
tips：文章结尾有开源地址，游戏数据都是本地的，改下IP运行起来就可以玩了。
直接上干货，首先是数据模型：
/// <summary> /// 用户信息 /// </summary> public class Customer { /// <summary> /// 唯一ID /// </summary> public string? ID { get; set; } /// <summary> /// 昵称 /// </summary> public string? NickName { get; set; } /// <summary> /// 卡片 /// </summary> public List<string> Card { get; set; } } /// <summary> /// 房间 /// </summary> public class Room { /// <summary> /// 房间名 /// </summary> public string Name { get; set; } /// <summary> /// 房主id /// </summary> public string Masterid { get; set; } /// <summary> /// 当前出牌人 /// </summary> public int Curr { get; set; } /// <summary> /// 当前卡片 /// </summary> public List<string> CurrCard { get; set; } = new List<string>(); /// <summary> /// 当前卡片打出人 /// </summary> public string ExistingCardClient { get; set; } /// <summary> /// 房间成员列表 /// </summary> public List<Customer> Customers { get; set; } = new List<Customer>(); }
tips：只是单纯为了斗D主设计的，商用版肯定不能这么搞，参考请慎用。
有了数据模型，自然少不了CRUD：
/// <summary> /// 用户操作 /// </summary> public static class CustomerAction { /// <summary> /// 用户列表 /// </summary> private static List<Customer> cusList = new List<Customer>(); /// <summary> /// 不存在则新增，存在则修改昵称 /// </summary> /// <param name="customer"></param> public static void Create(Customer customer) { Customer curr = null; if (cusList.Count > 0) curr = cusList.Where(x => x.ID == customer.ID).FirstOrDefault(); if (curr is null) cusList.Add(customer); else { curr.NickName = customer.NickName; Up4ID(curr); } } /// <summary> /// 用户列表 /// </summary> /// <returns></returns> public static List<Customer> GetList() { return cusList; } /// <summary> /// 获取单个 /// </summary> /// <param name="id"></param> /// <returns></returns> public static Customer GetOne(string id) { return cusList.Where(x => x.ID == id).FirstOrDefault(); } /// <summary> /// 删除用户 /// </summary> /// <param name="id"></param> public static void Delete(string id) { cusList.RemoveAll(x => x.ID == id); } /// <summary> /// 增加卡片 /// </summary> /// <param name="id"></param> /// <param name="cards"></param> public static void InCard(string id, List<string> cards) { Customer customer = cusList.Where(x => x.ID == id).FirstOrDefault(); if (customer.Card is null) customer.Card = cards; else customer.Card.AddRange(cards); Up4ID(customer); } /// <summary> /// 扣除卡片 /// </summary> /// <param name="id"></param> /// <param name="cards"></param> /// <param name="group"></param> /// <returns></returns> public static bool OutCard(string id, List<string> cards, Room group) { Customer client = cusList.Where(x => x.ID == id).FirstOrDefault(); if (client is null) return false; //卡片不匹配直接失败 if (client.Card.Where(x => cards.Contains(x)).ToList().Count != cards.Count) return false; //不符合出牌规则直接失败 if (!new Game.WithCard().Rule(group.CurrCard, cards, group.ExistingCardClient is null || group.ExistingCardClient == id)) return false; foreach (var item in cards) { client.Card.Remove(item); } group.CurrCard = cards; group.ExistingCardClient = id; Up4ID(client); RoomAction.Up4Name(group); return true; } /// <summary> /// 更新（根据ID） /// </summary> /// <param name="customer"></param> /// <returns></returns> public static bool Up4ID(Customer customer) { if (cusList.Count == 0) return false; cusList.RemoveAll(x => x.ID == customer.ID); cusList.Add(customer); return true; } } /// <summary> /// 房间操作 /// </summary> public static class RoomAction { /// <summary> /// 房间列表 /// </summary> private static List<Room> roomList = new List<Room>(); /// <summary> /// 新增房间 /// 如果房间已存在则不新增 /// </summary> /// <param name="group"></param> public static void Create(Room group) { if (!roomList.Where(x => x.Name == group.Name).Any()) roomList.Add(group); } /// <summary> /// 获取列表 /// </summary> /// <returns></returns> public static List<Room> GetList() { return roomList; } /// <summary> /// 获取单个 /// </summary> /// <param name="masterid">房主id</param> /// <param name="roomName">房间名称</param> /// <returns></returns> public static Room GetOne(string masterid = null, string roomName = null) { if (roomList.Count == 0) return null; if (masterid != null) return roomList.Where(x => x.Masterid == masterid).FirstOrDefault(); if (roomName != null) return roomList.Where(x => x.Name == roomName).FirstOrDefault(); return null; } /// <summary> /// 加入房间 /// </summary> /// <param name="client"></param> /// <param name="roomName"></param> public static bool Join(Customer client, string roomName) { if (roomList.Count == 0) return false; var room = roomList.Where(x => x.Name == roomName).FirstOrDefault(); if (room is null) return false; if (room.Customers.Count == 3) return false; room.Customers.Add(client); Up4Name(room); return true; } /// <summary> /// 删除房间 /// </summary> /// <param name="masterid">房主id</param> public static bool Delete(string masterid) { if (roomList.Count == 0) return false; var room = roomList.Where(x => x.Masterid == masterid).FirstOrDefault(); if (room == null) return false; roomList.Remove(room); return true; } /// <summary> /// 更新（根据房名） /// </summary> /// <param name="room"></param> /// <returns></returns> public static bool Up4Name(Room room) { if (roomList.Count == 0) return false; roomList.RemoveAll(x => x.Name == room.Name); roomList.Add(room); return true; } /// <summary> /// 更新当前出牌人 /// </summary> /// <param name="roomName"></param> /// <param name="index">传入则强制修改，不传按规则走</param> public static Customer ChangeCurr(string roomName, int index = -1) { var room = roomList.Where(x => x.Name == roomName).FirstOrDefault(); if (index != -1) room.Curr = index; else room.Curr = (room.Curr + 1) % 3; Up4Name(room); return room.Customers[room.Curr]; } }
因为所有数据都是通过静态属性保存的，所以大部分都是linq操作（原谅我linq水平有限）。
接下来是游戏逻辑：
/// <summary> /// 卡片相关 /// </summary> public class WithCard { /// <summary> /// 黑桃-S、红桃-H、梅花-C、方块-D /// BG大王，SG小王，14-A，15-2 /// </summary> readonly List<string> Cards = new List<string>() { "S-14","S-15","S-3","S-4","S-5","S-6","S-7","S-8","S-9","S-10","S-11","S-12","S-13", "H-14","H-15","H-3","H-4","H-5","H-6","H-7","H-8","H-9","H-10","H-11","H-12","H-13", "C-14","C-15","C-3","C-4","C-5","C-6","C-7","C-8","C-9","C-10","C-11","C-12","C-13", "D-14","D-15","D-3","D-4","D-5","D-6","D-7","D-8","D-9","D-10","D-11","D-12","D-13", "BG-99","SG-88" }; /// <summary> /// 发牌 /// </summary> public List<List<string>> DrawCard() { List<string> a = new List<string>(); List<string> b = new List<string>(); List<string> c = new List<string>(); Random ran = new Random(); //剩3张底牌 for (int i = 0; i < 51; i++) { //随机抽取一张牌 string item = Cards[ran.Next(Cards.Count)]; switch (i % 3) { case 0: a.Add(item); break; case 1: b.Add(item); break; case 2: c.Add(item); break; } Cards.Remove(item); } return new List<List<string>>() { a,b,c,Cards }; } /// <summary> /// 规则 /// </summary> /// <param name="existingCard"></param> /// <param name="newCard"></param> /// <param name="isSelf"></param> /// <returns></returns> public bool Rule(List<string> existingCard, List<string> newCard, bool isSelf) { //现有牌号 List<int> existingCardNo = existingCard.Select(x => Convert.ToInt32(x.Split('-')[1])).ToList().OrderBy(x => x).ToList(); //新出牌号 List<int> newCardNo = newCard.Select(x => Convert.ToInt32(x.Split('-')[1])).ToList().OrderBy(x => x).ToList(); //上一手是王炸，禁止其他人出牌 if (existingCardNo.All(x => x > 50) && existingCardNo.Count == 2) { if (isSelf) return true; else return false; } //王炸最大 if (newCardNo.All(x => x > 50) && newCard.Count == 2) return true; //单张 if (newCardNo.Count == 1) { if (existingCardNo.Count == 0) return true; if ((existingCardNo.Count == 1 && newCardNo[0] > existingCardNo[0]) || isSelf) return true; } //对子/三只 if (newCardNo.Count == 2 || newCardNo.Count == 3) { if (existingCardNo.Count == 0 && newCardNo.All(x => x == newCardNo[0])) return true; if (newCardNo.All(x => x == newCardNo[0]) && (isSelf || newCardNo.Count == existingCardNo.Count && newCardNo[0] > existingCardNo[0])) return true; } if (newCard.Count == 4) { //炸 if (newCardNo.All(x => x == newCardNo[0])) { if (existingCardNo.Count == 0 || isSelf) return true; if (existingCardNo.All(x => x == existingCardNo[0]) && existingCardNo.Count == 4) { if (newCardNo[0] > existingCardNo[0]) return true; } return true; } //三带一 { List<int> flagA = newCardNo.Distinct().ToList(); //超过2种牌直接失败 if (flagA.Count > 2) return false; //没有上一手牌，或者上一手是自己出的牌 if (existingCardNo.Count == 0 || isSelf) return true; int newCardFlag = 0; if (newCardNo.Where(x => x == flagA[0]).ToList().Count() > 1) { newCardFlag = flagA[0]; } else newCardFlag = flagA[1]; List<int> flagB = existingCardNo.Distinct().ToList(); //上一手牌不是三带一 if (flagB.Count > 2) return false; int existingCardFlag = 0; if (existingCardNo.Where(x => x == flagB[0]).ToList().Count() > 1) { existingCardFlag = flagB[0]; } else existingCardFlag = flagB[1]; if (newCardFlag > existingCardFlag) return true; } } if (newCard.Count >= 5) { bool flag = true; for (int i = 0; i < newCardNo.Count - 1; i++) { if (newCardNo[i] + 1 != newCardNo[i + 1]) { flag = false; break; } } //顺子 if (flag) { if (existingCardNo.Count == 0 || (newCardNo[0] > existingCardNo[0] && newCardNo.Count == existingCardNo.Count) || isSelf) return true; } } return false; } }
单张规则和普通斗D主一样（除了王以外2最大，其次是A），多张规则目前支持：王炸、对子、三只、顺子、三带一。目前只做到这里，各位同学可以拿回去自行扩展。
上一些运行图。房主建房并加入：

最后附上开源地址（客户端在web分支）：https://gitee.com/muchengqingxin/card-game
tips：前端同学在没有UI配合的情况下做到现在这样，必须给个赞。最后提醒大家，不要拿去商用。
