    questions: Game ideas and assembler

    1. Game ideas:

    Can anyone suggest a completely text-based, non graphical, non RPG / Action type game (ex: tic tac toe) that i could make to test my C++ skills? I cant think of any pure text based games. And im not doing Jeopardy .

    2. can you put multiple lines of assembler into code like this:

    extern "asm" {
    // ASM CODE HERE
    }

    ? Thanks all !
    Do not make direct eye contact with me.

    non RPG
    Hmm...what about writing a simple battle engine? Those are fun to make, at least more than tic tac toe.
    Well, there are a few things wrong with your code:

    1) It does not work.
    2) It does not work.
    3) It does not work.

    Hope this helps.

    To mix C and pure assembly modules there are a couple of things to remember.

    • If you are in TASM/MASM and are not using their variable passing macros - you must know the memory model you are coding for.
    • You must know the type of function call you are making - either C or PASCAL. This matters because of the order in which parameters are pushed onto the stack.
    • When using the ARG macro in TASM you absolutely must preserve bp, and restore it prior to returning to the caller. If you do not, C will crash hard when you return.
    • All integral return values are placed in (e)ax and all floating point return values are placed in st(0).
    • All assembly functions to be used with C MUST have an underscore placed in front of them - i.e.: _MyFunc proc
    • All assembly functions must be prototyped in your C module or in a header to be included with your module.


    There are others, but these are the most common mistakes - at least IMO.

    Examples:

    No parameters

    Assembly
    Code:
    public _MyFunc
    _MyFunc    proc
      ...
      ...
      ret
    _MyFunc    endp
    C
    extern "C" MyFunc(void)


    With parameters
    Assembly
    Code:
    public _MyFunc
    
    _MyFunc    proc
    ARG  x:WORD,y:WORD
    
      push  bp
      mov   bp,sp
      ...
      ...
      ret
    _MyFunc    proc
    C
    extern "C" MyFunc(int x,int y);


    AFAIK using extern with asm is not correct. I've never tried it so I'm not positive, but it does not make sense syntactically.

    I don't think I've ever seen a text based tetris, but there's nothing preventing it from being done. Do it.
    Away.

    Do it.
    Just do it.

    Battleships or a Memory game (flip two matching squares).

    My first *real* game was a breakout-clone, it wasn't text based (I used SDL), but I think it was a really good choice because I learned collision, map loading, input, and some other miscellanious stuff.

    a text based maze game is possible. if you want large mazes graphics would be your best option though.

    A fun one to program is Life.

    Have a matrix and living cells in it. If a cell is touching less that 2 other cells it dies of isolation, if it is touching more than 4 it dies of overcrowding, and if an empty space touches 3 living cells it is "born."

    www.gametutorials.com has a console (a.k.a.: text-based) maze tutorial (+ another you can get when you buy their cd)

    What's the deal with stealing Silvercord's avatar? I always think you're him. Get a new one.

    I didn't steal it from him, I found it on another board...anyways, why should I, it's not copyright infragment, and Silvercord hasn't said anything to me.
