我想添加行號對不起，我自己的 //我跑了提示和下面的錯誤彈出。前UBYTE線 //解析錯誤108 //解析錯誤之前滾動X 147 //解析錯誤之前滾動ý149 //解析錯誤之前scxCnt 151 //解析錯誤 //解析錯誤之前ScyCnt前153 32 207行 – user2939381

請重新格式化您的代碼，有太多的空白來看看發生了什麼。 – Dai

如果我知道如何正確地做到這一點，我會的。：/你想讓這些線條更接近一些嗎？行之間沒有空格？ – user2939381

您可能忽略一個包含文件中定義UBYTE。

嘗試過但它仍然沒有工作:(但謝謝你試圖幫助我:) – user2939381

你的問題是你綁定在函數中間定義新的變量。 GBDK編譯器不允許出於任何原因。（這顯然是ANSI C/C89標準的一部分）

您可以通過更改main()頂部從

int main(void){    //starts the main function 
int x,y,st,key,z;   //define the integers x and y wich will be used to define the hero position, key will be used later 
int x1,y1,st1;    
int x2,y2,st2;    
int x3,y3,st3;

解決這個問題，以這樣的：

int main(void){    //starts the main function 
    int x,y,st,key,z;   //define the integers x and y wich will be used to define the hero position, key will be used later 
    int x1,y1,st1; 
    int x2,y2,st2; 
    int x3,y3,st3; 

    //These variables are used later on. 
    UBYTE ScrollXCnt; 
    UBYTE ScrollYCnt; 
    BYTE SCXCnt; 
    BYTE SCYCnt; 
    UBYTE tempa, tempb; 
    UWORD Cnt;

或者，你可以將從這些變量開始的所有代碼移動到另一個函數，然後這些變量將用函數聲明，並且一切都會正常。

嘿謝謝。我一直沒有在這個項目上工作過一段時間，因爲我一直在做我的ds遊戲，但我會回頭看看這個項目，並解決我做錯了什麼。 – user2939381
