如何在 Assembly 中使用鼠标？

Question

我需要编写一个汇编代码，如果你点击屏幕上的特定图标，就会激活一个声音。（例如：钢琴）怎么做？

我正在使用 Assembly 86 和 dosbox 0.74-3 如果有帮助。

这是创建钢琴的代码（5 个白色矩形）我需要当鼠标点击其中一个矩形时，它会发出声音。

我知道如何发出声音，我只需要在单击图标时听到声音即可。备注是希伯来语因为是我的母语

您的代码已经在等待左键单击：

MouseLP:
    mov     ax, 0003h   ; MOUSE.GetMousePosition
    int     33h         ; -> BX CX DX
    test    bx, 1       ; Is left button down?
    jz      MouseLP     ; No
    shr     cx, 1       ; Adjust cx to range 0-319, to fit screen

一旦点击到达，您就开始将您在 CX (X) 和 DX (Y) 中获得的坐标与您感兴趣的矩形的坐标进行比较：

您所有的矩形都具有相同的宽度 (25) 和高度 (150)。
下一个片段将检查鼠标是否在您的第一个矩形上方单击，其左上角位于 (Player_CoordinateIn_X1, Player_CoordinateIn_Y).

    mov     ax, [Player_CoordinateIn_X1]  ; UpperLeftCornerX
    cmp     cx, ax
    jb      Outside
    add     ax, 25-1                      ; LowerRightCornerX
    cmp     cx, ax
    ja      Outside
    mov     ax, [Player_CoordinateIn_Y]   ; UpperLeftCornerY
    cmp     dx, ax
    jb      Outside
    add     ax, 150-1                     ; LowerRightCornerY
    cmp     dx, ax
    ja      Outside
Inside:
    ... Make the corresponding sound!
Outside:
    ... Go check for another mouse click!

proc drawIcon
 add [bp],10
 push bp
 mov bp,sp

您的 drawIcon 过程以这条奇怪的指令开始 add [bp],10。它应该做什么？
