ASM

[peckitt99]

does anyone know how to write a getkey command for ASM programming for the 80x86 processor?

It's easy if you've learned some assembly first.

this is what i have soo far, plese let me know if im wrong.

mov ah, 11
int 16h

now im stuck with the next bit of the code.

also do you know how to do clearscreen without using dos and bios functions?

Thanks

Why don't you use asm to call C functions? That is much easier.

[peckitt99]

well our assignment is written in c code but we have to fill in the rest of the functions using ASM

[manutd]

Show us your assignment. Also, you might want to consider a book like Assembly Step-by-step.

[peckitt99]

my assignment is too big to put up on here, i do have a few books but its not really that good, lol. but like i said in the other post i just have to fill out functions with the asm code rather than all in c. (The Program is "MineSweeper")

Try giving us, say, one function that you need.

[peckitt99]

here is a clip with a few functions that is needed

    // Clear screen and output the title and points text
    ClearWindow(0,0,SCREEN_WIDTH-1,SCREEN_HEIGHT-1,BLOCK_CHAR, BLUE_ON_BLUE);
    WriteAt(TitleStr.X, TitleStr.Y, TitleStr.Text, YELLOW_ON_BLUE);
    WriteAt(NumGoesStr.X, NumGoesStr.Y, NumGoesStr.Text, NumGoesStr.Colour);

    // Draw the sea
    ClearWindow(GridLeft,GridTop,GridLeft+GridWidth-1,GridTop+GridHeight-1,SEA_CHAR, WHITE_ON_BLUE);

    // Enable the dos mouse cursor and enter the game-on loop until killed or quit using escape
    MouseCursorOn();

    do
    {
      // Get mouse position and test whether left button is down. If it is then wait for it to be
      // released.  If the mouse is in the grid area, check if it is on a mine. If it is then
      // game over and exit this loop. If not, write the risk value on the grid and update
      // the points string
      ReadMouse(&Mouse);
      GotoXY(Mouse.Col,Mouse.Row);
      if (Mouse.Buttons.Button.Left == PRESSED)
      {
        while (Mouse.Buttons.Button.Left == PRESSED) ReadMouse(&Mouse); // Wait for release

        if (Mouse.Col >= GridLeft && Mouse.Col < GridLeft+GridWidth &&
            Mouse.Row >= GridTop &&  Mouse.Row < GridTop+GridHeight)
        {
           if (Grid[Mouse.Row-GridTop][Mouse.Col-GridLeft] == A_MINE)
           {
             GameOver();

You're not in DOS any more (probably). Windows works a bit differently.

[peckitt99]

ah right im using turbo debugger if that help and the other functions that i need to complete are

ClearWindow
WriteAt 
StrLen
IntToStr
GetKey
StrCpy 
MouseCursorOff and Off
ReadMouse
MemSet

anyone know of any good websites that can help me learn this?

MouseCursorOff and Off

->

MouseCursorOff and On

?

You could try google . . . http://www.google.ca/search?hl=en&q=...tutorial&meta=

Mouse cursor on

DOS
_asm {
  mov ax,0001h
  int 33h
}

Windows
ShowCursorPos(TRUE);


Mouse cursor off

DOS
asm  {
  mov ax,0002h
  int 33h
}

Windows
ShowCursorPos(FALSE);

For keyboard you want to hook interrupt 09h, not the BIOS key handler at 16H.
