1. 创建 Blazor web工程,选Auto
2. 打开 GitHub Copilot 窗口,输入提示词
使用 Blazor 编一个五子棋游戏
3.复制代码测试
为了方便调试, 我们先把运行模式由 InteractiveAuto 改为 InteractiveServer
打开 App.razor 编辑 两行 @rendermode="InteractiveAuto" 改为 @rendermode="InteractiveServer"
4.不出意外, 代码出现了意外
无脑使用AI修复一下
结果发现不是这个问题. 是逻辑代码 @onclick="() => PlacePiece(x, y)" 问题. 原因是PlacePiece闭包捕获的 x、y 是当前循环的值
既然人工发现了问题, 我们继续提醒一下AI, 尝试修复
最后还是没修复成功, 手动处理一下

}
说明:
- 添加 int _x = x; int _y = y; 确保闭包捕获的
_x
、_y
是当前循环的值,避免 Blazor 渲染时闭包变量引用错误。 - 在
PlacePiece
方法开头增加边界检查,防止非法坐标导致数组越界异常。
这样可以彻底修复 PlacePiece
拿到的变量不正确和越界的问题。
5. 运行效果
6. 加入显示当前玩家的得分功能
你可以为每个玩家增加一个分数变量,每次有玩家获胜时将其分数加一,并在界面上显示。下面是具体实现方法:
- 在
@code
区域添加分数字段:
int blackScore = 0;
int whiteScore = 0;
- 在玩家获胜时更新分数:
void PlacePiece(int x, int y)
{if (x < 0 || x >= BoardSize || y < 0 || y >= BoardSize)return;if (winner != 0 || board[x, y] != 0)return;board[x, y] = currentPlayer;if (CheckWin(x, y, currentPlayer)){winner = currentPlayer;if (winner == 1)blackScore++;else if (winner == 2)whiteScore++;}else{currentPlayer = 3 - currentPlayer; // 切换玩家}
}
- 在页面上显示分数(比如在标题下方):
<div style="margin-bottom:10px;">当前玩家: <b>@(currentPlayer == 1 ? "黑子" : "白子")</b><span style="margin-left:20px;">黑子得分: <b>@blackScore</b></span><span style="margin-left:20px;">白子得分: <b>@whiteScore</b></span>@if (winner != 0){<span style="color:red;margin-left:20px;">胜者: @(winner == 1 ? "黑子" : "白子")</span><button class="btn btn-primary" style="margin-left:20px;" @onclick="Restart">重新开始</button>}
</div>
这样每次有玩家获胜时,分数都会自动更新并显示在页面上。
7. 加入重置得分功能
你可以在 Restart
方法中增加对分数的重置,或者单独添加一个“重置得分”按钮和方法。推荐做法如下:
- 添加重置得分方法:
void ResetScore()
{blackScore = 0;whiteScore = 0;
}
- 在页面上添加按钮:
<button class="btn btn-danger" style="margin-left:20px;" @onclick="ResetScore">重置得分</button>
建议将此按钮放在分数显示附近,例如:
<div style="margin-bottom:10px;">当前玩家: <b>@(currentPlayer == 1 ? "黑子" : "白子")</b><span style="margin-left:20px;">黑子得分: <b>@blackScore</b></span><span style="margin-left:20px;">白子得分: <b>@whiteScore</b></span><button class="btn btn-danger" style="margin-left:20px;" @onclick="ResetScore">重置得分</button>@if (winner != 0){<span style="color:red;margin-left:20px;">胜者: @(winner == 1 ? "黑子" : "白子")</span><button class="btn btn-primary" style="margin-left:20px;" @onclick="Restart">重新开始</button>}
</div>
这样点击“重置得分”按钮即可将分数清零。
8. 在这个五子棋游戏中添加 AI 对手功能
在你的 Blazor 五子棋游戏中添加 AI 对手功能,常见做法是让一方(如白子)由 AI 自动落子。实现思路如下:
- 判断当前玩家是否为 AI:如 currentPlayer == 2 时,自动调用 AI 落子逻辑。
- 实现 AI 落子算法:可以先用简单的随机落子,后续可扩展为更智能的算法。
- 在玩家落子后自动触发 AI 落子:用
StateHasChanged()
刷新界面,必要时用await Task.Delay()
增加落子延迟。
下面是具体实现方法(以白子为 AI):
@page "/"<PageTitle>五子棋</PageTitle><h1>五子棋游戏</h1><div style="margin-bottom:10px;">当前玩家: <b>@(currentPlayer == 1 ? "黑子" : "白子(电脑)")</b><span style="margin-left:20px;">黑子得分: <b>@blackScore</b></span><span style="margin-left:20px;">白子得分: <b>@whiteScore</b></span><button class="btn btn-danger" style="margin-left:20px;" @onclick="ResetScore">重置得分</button>@if (winner != 0){<span style="color:red;margin-left:20px;">胜者: @(winner == 1 ? "黑子" : "白子(电脑)")</span><button class="btn btn-primary" style="margin-left:20px;" @onclick="Restart">重新开始</button>}
</div><table style="border-collapse:collapse;">@for (int y = 0; y < BoardSize; y++){<tr>@for (int x = 0; x < BoardSize; x++){int _x = x;int _y = y;<td style="width:32px;height:32px;border:1px solid #888;text-align:center;vertical-align:middle;cursor:pointer;background:@GetCellBg(x, y);"@onclick="@(() => PlacePiece(_x, _y))">@if (board[x, y] == 1){<span style="font-size:24px;color:black;">●</span>}else if (board[x, y] == 2){<span style="font-size:24px;color:#eee;text-shadow:0 0 2px #888;">●</span>}</td>}</tr>}
</table>@code {const int BoardSize = 15;int[,] board = new int[BoardSize, BoardSize];int currentPlayer = 1; // 1: 黑子, 2: 白子(电脑)int winner = 0;int blackScore = 0;int whiteScore = 0;Random rand = new();void PlacePiece(int x, int y){if (winner != 0 || board[x, y] != 0 || currentPlayer == 2)return;board[x, y] = currentPlayer;if (CheckWin(x, y, currentPlayer)){winner = currentPlayer;if (winner == 1)blackScore++;else if (winner == 2)whiteScore++;}else{currentPlayer = 2;StateHasChanged();_ = AITurnAsync();}}async Task AITurnAsync(){await Task.Delay(500); // AI 落子延迟if (winner != 0) return;// 简单随机落子var empty = new List<(int x, int y)>();for (int i = 0; i < BoardSize; i++)for (int j = 0; j < BoardSize; j++)if (board[i, j] == 0)empty.Add((i, j));if (empty.Count == 0) return;var (aiX, aiY) = empty[rand.Next(empty.Count)];board[aiX, aiY] = 2;if (CheckWin(aiX, aiY, 2)){winner = 2;whiteScore++;}else{currentPlayer = 1;}StateHasChanged();}// 其余代码不变...bool CheckWin(int x, int y, int player){int[][] directions = new int[][]{new int[]{1,0}, new int[]{0,1}, new int[]{1,1}, new int[]{1,-1}};foreach (var dir in directions){int count = 1;count += CountDirection(x, y, dir[0], dir[1], player);count += CountDirection(x, y, -dir[0], -dir[1], player);if (count >= 5)return true;}return false;}int CountDirection(int x, int y, int dx, int dy, int player){int count = 0;for (int step = 1; step < 5; step++){int nx = x + dx * step;int ny = y + dy * step;if (nx < 0 || nx >= BoardSize || ny < 0 || ny >= BoardSize)break;if (board[nx, ny] == player)count++;elsebreak;}return count;}void Restart(){board = new int[BoardSize, BoardSize];currentPlayer = 1;winner = 0;}void ResetScore(){blackScore = 0;whiteScore = 0;}string GetCellBg(int x, int y){return (x + y) % 2 == 0 ? "#f9d77e" : "#eac066";}
}
要点说明:
- 玩家(黑子)落子后自动触发 AI(白子)落子。
- AI 采用随机空位落子,简单易懂,后续可扩展为更智能算法。
- 若要让 AI 先手,只需将
currentPlayer = 2
并在OnInitialized
或Restart
时调用AITurnAsync()
。
用是能用了, 就是这个AI太傻了,继续优化一下
要优化五子棋 AI 的落子策略,可以采用“优先级评分法”来提升难度。基本思路如下:
- 优先考虑能直接获胜的位置(如 AI 连成五子)。
- 阻止玩家获胜(如玩家有四连,AI 必须堵住)。
- 优先进攻(如自己有三连、二连)。
- 其次防守(如玩家有三连、二连)。
- 否则随机或选择评分最高的位置。
下面是一个简单的评分法实现,AI 会优先选择能赢、能防守、能进攻的位置:
async Task AITurnAsync()
{await Task.Delay(500);if (winner != 0) return;var (aiX, aiY) = FindBestMove();board[aiX, aiY] = 2;if (CheckWin(aiX, aiY, 2)){winner = 2;whiteScore++;}else{currentPlayer = 1;}StateHasChanged();
}// 简单评分法:优先赢棋、阻挡对方、进攻
(int, int) FindBestMove()
{int maxScore = int.MinValue;var bestMoves = new List<(int x, int y)>();for (int x = 0; x < BoardSize; x++){for (int y = 0; y < BoardSize; y++){if (board[x, y] != 0) continue;int score = EvaluatePoint(x, y, 2); // AI进攻score = Math.Max(score, EvaluatePoint(x, y, 1)); // 防守if (score > maxScore){maxScore = score;bestMoves.Clear();bestMoves.Add((x, y));}else if (score == maxScore){bestMoves.Add((x, y));}}}// 多个最佳点时随机选一个return bestMoves[rand.Next(bestMoves.Count)];
}// 评分函数:可根据实际需要调整权重
int EvaluatePoint(int x, int y, int player)
{int score = 0;int opponent = player == 1 ? 2 : 1;// 检查4连、3连、2连等foreach (var dir in new[] { (1, 0), (0, 1), (1, 1), (1, -1) }){int count = 1 + CountDirection(x, y, dir.Item1, dir.Item2, player)+ CountDirection(x, y, -dir.Item1, -dir.Item2, player);if (count >= 5) score += 10000; // 直接获胜else if (count == 4) score += 1000;else if (count == 3) score += 100;else if (count == 2) score += 10;// 防守分数int oppCount = 1 + CountDirection(x, y, dir.Item1, dir.Item2, opponent)+ CountDirection(x, y, -dir.Item1, -dir.Item2, opponent);if (oppCount >= 5) score += 9000; // 必须防守else if (oppCount == 4) score += 900;else if (oppCount == 3) score += 90;else if (oppCount == 2) score += 9;}return score;
}
集成方法:
- 替换你的
AITurnAsync
方法为上述实现。 - 在
@code
区域添加FindBestMove
和EvaluatePoint
方法。 - 可根据实际效果调整评分权重。
效果说明:
- AI 会优先选择能赢的位置,其次堵住玩家的四连,再考虑进攻和防守三连、二连。
- 这种评分法简单高效,能显著提升 AI 难度。
- 若需更高难度,可进一步实现“活三”、“活四”识别、双向评分、甚至 Minimax 算法。
9. 添加难度切换按钮
添加三个难度选择按钮以及切换人机按钮
下面是实现“三个难度选择按钮(简单、中等、困难)”和“人机/人人切换按钮”的完整方法。
难度通过调整 AI 的评分权重实现,人机切换通过 isHumanVsAI
控制。请直接替换你的 Home.razor

}
说明:
- “简单”AI为随机落子,“中等/困难”AI为评分法,困难权重更高更难。
- “人机对战”时白子为AI,“人人对战”时双方均为玩家。
- 切换难度或模式会自动重开棋局。
- 你可以根据需要调整权重数组以微调难度。
