C# 递归错误？

Question

我有很奇怪的问题。 我正在使用递归方法，该方法应该在 6 个玩家（5 个机器人和 1 个玩家）之间轮换，但是一旦它到达 bot 5（这是最后一个），它就不会完全执行此操作，它会跳过玩家的回合并离开到 bot 1、bot 2、bot 3、bot 4、bot 5，然后轮到玩家，换句话说，它跳过了一个玩家回合。 我将在这里原始粘贴代码，如果有不清楚的地方请在评论中解释。

听起来你想以更有状态的方式来解决这个问题。 一个简化的例子可能是：

// Player interface - the game engine will pass game state to the TakeTurn method
// The target of the TakeTurn call can mutate the game state
public interface IPlayer {

    void TakeTurn(GameState state);

    // Some info that other bots/players might need to look at
    int Chips { get; } 

    // also add other useful bits of info that other game components may need
    int SomeOtherUsefulInfo { get; }
}

public class GameState {

    // Is the game over?
    bool GameOver;

    // State information the bots/player will use to make decisions
    int ChipsInPot;

    // Reference to previous player which could help with AI decisions etc
    IPlayer previousPlayer;          
}

// Both Bot and Human class implement IPlayer which means they can both
// be handled by the same game pipeline step but have radically different
// implementations - such as AI or manual interaction
public class Bot : IPlayer {
    // AI here making sure to implement the IPlayer interface
}

public class Human : IPlayer {
    // Human player handling code but with same interface
}

// Game engine simply runs a loop to keep passing turns
public class GameEngine {
    GameState _state;
    List<IPlayer> _players;

    public GameEngine() {
       _players = new List<IPlayer>();
       _players.Add(new Bot("Fred"));
       _players.Add(new Bot("James"));
       _players.Add(new Bot("Arnold"));
       _players.Add(new Human("Jake")); 
    }

    public void GameLoop() {

        while(!_state.GameOver) {
          foreach(var player in _players) {
              player.TakeTurn(_state); // etc - keep mutating state and looping until the game ends

              // Add more complexity here :)
          }
        }
    }
}
