布爾二維數組C＃使多個值爲真

你好，我剛剛完成了一個網格的代碼。這些說明可讓您右移，左移，上移或下移並輸入特定值以移動。但是現在的問題是，輸入哪個值是唯一成爲真實的位置。我試圖讓全部變成真實。例如fi我們右移3，它應該是3點= true而不是最後一個。任何人都可以幫助我嗎？布爾二維數組C＃使多個值爲真

幾件事情1）'如果（好吧==假）'將永遠是真實的，因此沒有必要，因爲你只能從做突破，而循環後設置好=假2）在你的while循環中，你有競爭檢查'鑽[check_column，check_row] == true && .. &&鑽[check_column，check_row]！= true' 3）你永遠不會遞減 'new_distance'在你的while循環中4）你能否澄清你的意思_3 spots = true_。我沒有看到你在哪裏設置任何東西，除了在你的初始化 –

好吧，例如，如果我要輸入「r」，然後「2」，那麼它應該使網格上的這兩個點是真實的，但現在，它的唯一將EXACT值2設置爲原來的值爲true – SaltyLegend

要回答你的問題，你是不是看到每個移動爲安全的原因是因爲你不檢查每一個位置，你只需設置你的檢查位置，你想移動的位置，而不是每個增量位置。我在這個答案中增加了一個更多邏輯的類，因爲你遊戲中的每一步都需要稍微不同的邏輯來工作。

因此，這將檢查每一步？ – SaltyLegend

@SaltyLegend。是的，這將檢查每一步。我編輯了我的答案，因爲我忘了將嘗試移動的結果設置爲好值。另外，我添加了一些示例輸出。 –

啊謝謝，但我也必須實際使用-1，-5的值。 200,400值只是設置2d數組，但是對於要打印的值，它們將是-1 - +數字和-5 - +數字，所以我需要更改哪些值？ – SaltyLegend
