输出棋盘到装配x86中的控制台？

Question

我正在研究x86的Assembly，并试图在控制台中“绘制”或输出8x8白色和灰色棋盘。 我还是汇编语言的新手，我运气不佳：/想知道是否有在x86汇编编程方面有更多经验的人可以帮助并指出正确的方向？

我做了一个程序，然后以多种背景色/原色输出了一组“ char”，这就是我将以下内容拼凑在一起的地方：

COUNT = 7
ROWCNT = 7

.data
    text BYTE "__", 0
    text2 BYTE "00", 0
.code
main PROC
L1:
    mov eax,gray+(gray*16)
    call SetTextColor
    mov edx, offset text
    call writeString
    mov ebx, COUNT
    dec ebx

    mov eax,white+(white*16)
    call SetTextColor
    mov edxecx, offset text3

    decpush ebxecx

    mov eax,gray+(gray*16)

    mov eax ,white+(white*16)

    mov eax,white+(white*16)

    decloop ebxL1

    fourthSetTiles:

mov eax,gray+(gray*16)
    call SetTextColor
    mov edx, offset texttext2
    call writeString
    dec ebx

    cmp ebx, 0
    je eigthRowTile


    jmp L1WriteString

eigthRowTile:
    mov eax,green+(white*16)
    call SetTextColor
    mov edx, offset text2
    call writeStringWriteString

exit
exit
main ENDP
END main

我当前的输出如下。 我正在获取8个不同的“平铺”，但现在想并尝试在更大范围内寻找是否有人可以帮助的方法？ 生成此输出8次（不匹配的图块颜色）

我正在尝试在控制台中创建8x8网格。 任何人都有建议，技巧或想法吗？ 一如既往的协助表示赞赏！ :)

Answer 1

我不知道函数“ setTextColor”，但是人们可以做出有根据的猜测，即它希望在eax中使用一种颜色（默认的位置是为子程序放置一个参数）。

在这种情况下，序列

   mov eax, gray
   mov eax, ecx

似乎将颜色指示常量加载到eax中，然后将其替换为ecx中的随机垃圾。 那不会产生有用的结果。 您用黑色犯了同样的错误。

虽然颜色编码不错，但您真正想要的是指示棋盘上的棋子。 我已经在70年代完成了这个汇编器（哎呀！），使用类似以下的方法（OP来填充必要的汇编器详细信息）：

  White equ 0  ; tags a piece as "white"
  Black equ 8  ; tags a piece as "black"
  Empty equ 0  ; empty square
  Pawn equ 1    ; piece codes
  Knight equ 2
  Bishop equ 3
  Rook equ 4
  Queen equ 5
  King equ 6
  CastledKing equ 7 ; you need to distinguish this from an uncasteled king!

  ChessBoard equ $
      byte White+Rook, White+Knight, White+Bishop, White+Queen, White+King, White+Bishop, White+Knight, White+Rook
      byte Empty, Empty, Empty, Empty, Empty, Empty, Empty, Empty
      byte Empty, Empty, Empty, Empty, Empty, Empty, Empty, Empty
      byte Empty, Empty, Empty, Empty, Empty, Empty, Empty, Empty
      byte Empty, Empty, Empty, Empty, Empty, Empty, Empty, Empty
      byte Empty, Empty, Empty, Empty, Empty, Empty, Empty, Empty
      byte Empty, Empty, Empty, Empty, Empty, Empty, Empty, Empty
      byte Black+Rook, Black+Knight, Black+Bishop, Black+Queen, Black+King, Black+Bishop, Black+Knight, Black+Rook

   PieceCharacter byte ".PNBRQKk"


   main:
       call PrintBoard
       xor  eax, eax
       call Exit

  PutSpace:
        mov  eax, 0x20
        call  PutCharacter
        ret

  PutNewline:
        mov   eax, 0x0d
        call  PutCharacter
        mov   eax, 0x0a
        call  PutCharacter
        ret

   PrintBoard:
        call  PutNewline
        push  7 ; row count
    printrow:
        push  7 ; column count
    printsquarecontent:
        mov   eax, 4[esp] ; row number
        shl   eax, 3
        add   eax, 0[esp] ; column number
        mov   eax, ChessBoard[eax] ; get piece on board
        test  eax, eax
        jne   printpiece
        call   PutSpace
        mov    eax, '.'
        call   PutCharacter
        jmp    printnextpiece

    printpiece:
        push   eax   ; save piece
        test   eax, Black
        mov    eax, 'w'
        je     printpiececolor
        mov    eax, 'b'
    printpiececolor:
        call    PutCharacter
        pop     eax
        and     eax, 0x7   ; extract just the piece number
        mov     eax, PieceCharacter[eax]
        call    PutCharacter

   printnextpiece:
        call    PutSpace
        dec     0[esp]
        jns     printsquarecontent
        lea     esp, 4[esp] ; pop useless column count
        dec     0[esp]
        jnz     printrow
        lea     esp, [esp]
        ret

这应该打印类似：

        bR bN bB bQ bK bB bN bR
         .  .  .  .  .  .  .  .
         .  .  .  .  .  .  .  .
         .  .  .  .  .  .  .  .
         .  .  .  .  .  .  .  .
         .  .  .  .  .  .  .  .
         .  .  .  .  .  .  .  .
        wR wN wB wQ wK wB wN wR

不是特别优雅，但是足够可读，可以下棋。 OP可以使用颜色更改来代替“ b”或“ w”。
