井字棋帮助修复方法，用于检查是否已选择正方形。游戏板的结构为空数组

Question

我正在使用Ruby在命令行中创建井字游戏。我有一个display_board方法，可以在命令行中将我的数组显示为游戏板，当我玩游戏时，玩家可以在1-9之间进行选择，并在其正方形中填充“符号”。我创建了一个方法check_square来验证网格中的一个正方形是否已被采用，但对我来说不能正常工作。我开始游戏，一切正常，直到要求我选择网格上的第一个数字。它立即做出响应，并告诉我该号码已被使用，即使这是游戏的第一步。它要求我选择另一个数字，并在第二次尝试中填充网格。它会在每个玩家移动时执行此操作。这种逻辑对我来说似乎很有意义，我一直在努力解决一个小时，但是我显然忽略了一些东西。向正确方向的任何推动都会有所帮助！

Answer 1

@@board[move] == "#{player_one.symbol}" || "#{player_two.symbol}"

此逻辑是要检查是否有任一玩家符号存储在棋盘上的所选位置。它真正在做的是检查玩家的符号是否存储在板上的该位置，如果不是，则将玩家的符号的字符串文字评估为真。[[always。

尝试以下方法：
@@board[move] == "#{player_one.symbol}" || @@board[move] == "#{player_two.symbol}"
