如何在汇编中使用鼠标？

Question

I need to write an assembly code that if you click a particular icon on a screen, a sound is activated.(For example: piano) How to do it?

I'm using a Assembly 86 and dosbox 0.74-3 If that helps.

This is the code that creates the piano (5 white rectangles) I need that when the mouse clicks on one of the rectangles, it will make a sound.

I know how to make a sound, I just need the sound to be heard when the icons are clicked. The remarks are in Hebrew because it is my native language

Answer 1

Your code already waits for a left button click:

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

Once the click arrives you start comparing the coordinates that you got in CX (X) and DX (Y) with the coordinates of the rectangle that interests you:

All of your rectangles have the same width (25) and height (150).
Next snippet will check if the mouse was clicked while above your first rectangle, whose upperleft corner is at (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

Your drawIcon proc starts with this strange instruction add [bp],10 . What's it supposed to do?
