之前開內(nèi)部培訓(xùn)，說(shuō)到實(shí)時(shí)web應(yīng)用這一塊講到了SignalR，我說(shuō)找時(shí)間用它做個(gè)游戲玩玩，后面時(shí)間緊張就一直沒安排。這兩天閑了又想起這個(gè)事，考慮后決定用2天時(shí)間寫個(gè)斗D主，安排了前端同學(xué)寫客戶端，我寫游戲邏輯和服務(wù)。

這個(gè)項(xiàng)目難度并不高，但是游戲邏輯還是挺繞的，聯(lián)調(diào)過(guò)程中也發(fā)現(xiàn)解決了很多小問(wèn)題。來(lái)園子里整理一篇文章，記錄一下。

基礎(chǔ)的介紹就免了，畢竟官網(wǎng)跟著走兩圈啥都懂了。沒基礎(chǔ)的可以戳這里，是我之前寫的一篇SignalR基礎(chǔ)介紹，帶有一個(gè)極簡(jiǎn)聊天室。

tips：文章結(jié)尾有開源地址，游戲數(shù)據(jù)都是本地的，改下IP運(yùn)行起來(lái)就可以玩了。

直接上干貨，首先是數(shù)據(jù)模型：

/// <summary>
    /// 用戶信息
    /// </summary>
    public class Customer
    {
        /// <summary>
        /// 唯一ID
        /// </summary>
        public string? ID { get; set; }

        /// </summary>
        public string? NickName { get; set; }

        /// <summary>
        /// 卡片
        /// </summary>
        public List<string> Card { get; set; }
    }


    /// <summary>

        public string Name { get; set; }

        /// <summary>

        public string Masterid { get; set; }

        /// <summary>

        /// </summary>
        public int Curr { get; set; }

        /// <summary>
        /// 當(dāng)前卡片
        /// </summary>
        public List<string> CurrCard { get; set; } = new List<string>();

        /// <summary>
        /// 當(dāng)前卡片打出人
        /// </summary>
        public string ExistingCardClient { get; set; }

        /// 房間成員列表
        /// </summary>
        public List<Customer> Customers { get; set; } = new List<Customer>();

tips：只是單純?yōu)榱硕稤主設(shè)計(jì)的，商用版肯定不能這么搞，參考請(qǐng)慎用。

因?yàn)樗袛?shù)據(jù)都是通過(guò)靜態(tài)屬性保存的，所以大部分都是linq操作（原諒我linq水平有限）。
