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 :D .

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

extern "asm" {
// ASM CODE HERE
}

? Thanks all :D !

Hmm...what about writing a simple battle engine? Those are fun to make, at least more than tic tac toe.

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.

Just do it.

How bout a maze game... you can try working with AI, collision detection etc.

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.

Yeah dude, everytime I see that I think that you're some uber-inflatted egotistical graphics programmer. (hahaha jk...)

Silvercord hasn't been around for a few days. He'll say something when he comes back. He'll probably kill you and feed you to his mother or something like that.

AHHHHHHHHHHHHHHHHHHHH!!!!!!!! NNNNNNNNNNNNNNOOOOOOO!!!!!!!!!!!

[sigh]

I pity his dog :D

Anyways... I say HANGMAN!!! :) heh... j/k. I think life would be a cool one, I believe I might just try that out myself (though with graphics prolly) ;)
