C＃控制檯蛇尾將不會被刪除

我需要在C＃控制檯應用程序中編寫蛇遊戲。我有一條可以移動的蛇，但唯一的問題是它的尾巴不會被切斷，這意味着你可以基本上保持每一步的成長，而不用吃一塊。如果你能幫助我，我會很高興。下面的代碼：C＃控制檯蛇尾將不會被刪除

你不只是ArrSnakeItSelfX[0]這是蛇的頭部，而沒有吃動更新任何ArrSnakeItSelfX的座標。陣列中的所有其他座標都是錯誤的，所以

Console.SetCursorPosition(ArrSnakeItselfX[i - 1], ArrSnakeItselfY[i - 1]); 
Console.Write(" ");

總是寫入相同的屏幕位置。

當你的蛇沒有進食時，你必須將你的所有座標都移到後面。因此，最後一個位置（舊尾部）被擦除，並在數組中的索引0處插入新的頭部位置。

var e = ArrSnakeItselfX.Length; 

Console.SetCursorPosition(ArrSnakeItselfX[e - 1], ArrSnakeItselfY[e - 1]); 
Console.Write(" "); //erase tail of snake 

for (int i = e-1; i>0; i--) { //shift all coordinates by one position in the array 
    ArrSnakeItselfX[i] = ArrSnakeItselfX[i-1]; 
    ArrSnakeItselfY[i] = ArrSnakeItselfY[i-1]; 
} 

//set new head position 
ArrSnakeItselfX[0] = //new x of head; 
ArrSnakeItselfY[0] = //new y of head; 
Console.SetCursorPosition(ArrSnakeItselfX[0], ArrSnakeItselfY[0]); 
Console.Write("@");

當你吃東西，你基本上做同樣的事情，只是，你不降的最後一個元素，而是由一個增加ARRAYSIZE並保持最後一個元素。

非常感謝！我仍然需要加強代碼，但現在我差不多完成了！ – gogonamee

例如，您可以使用'List '來代替兩個數組，因爲一個點可以同時保存座標和一個列表，您可以刪除最後一個元素並在前面插入一個新元素，因此您不必複製所有移位元素 – derpirscher

我知道，但是這是一個學校的項目，並且指令使用數組。 – gogonamee
