任务35：后端-对出牌进行牌型判断与出牌规则逻辑
回顾下Type中牌型：\Server\ET.Core\Landlords\Component\Type.cs
/// <summary> /// 出牌类型 /// </summary> public enum CardsType { None, JokerBoom, //王炸 Boom, //炸弹 OnlyThree, //三张 ThreeAndOne, //三带一 ThreeAndTwo, //三带二 Straight, //顺子 五张或更多的连续单牌 DoubleStraight, //双顺 三对或更多的连续对牌 TripleStraight, //三顺 二个或更多的连续三张牌 Double, //对子 Single //单牌 }
梳理下CardHelper提供的几个关键方法
- public static async Task<List<Card[]>> GetPrompt 获取提示出牌
-
public static bool PopEnable 判断牌型与出牌规则
-
public static void SortCards 牌组排序
-
public static int GetWeight 获取牌组权重
MapHelper添加出牌辅助类CardHelper，类中添加上面这静态些方法 \Server\Hotfix\Helper\MapHelper.cs
记得MapHelper上面加上新的using
using System.Threading.Tasks; using System.Linq;
/// <summary> /// 斗地主出牌辅助方法 /// </summary> public static class CardHelper { }

斗地主的核心算法都在这里了，你需要用开发者的思维理清楚斗地主的玩法规则，具体的牌型判断方法代码与注释都很清晰，好好思考都能明白。
本节主要是出牌算法与逻辑，大家自行消化，下节我们实现了前端的请求后再测试效果。
