Thread: Text-Based Space Simulator

Latly Ive been working on a space simulator called Vacuus.
However I'm not sure how I could establish the player position, heres what I've done:

I've created a pointer that points to a pacific location in a 2d array.
Now what I want to do is let the player input 1 number , which will then change what ever the pointer was pointing in 1 dimension of the array. Does anyone know how to do that, or would I need 2 pointers?

The mGame source can be found @ http://vacuus.hostrim.com/source_mgame.html

The menu can be found @ http://vacuus.hostrim.com/source01.html

Thx in advance

You must have a DOS compiler.

Code:

void SetMode(void)
{
  REGS regs;
  regs.x.ax=0x13;
  int86(0x10,& regs,& regs);
}

So that code wont work in Dev C++
(heard it ould somewher, just tried it didnt work)
Would DJGPP work
Or is there away to get it to work in Dev C++?

DJGPP should work because it is a DOS compiler, but there still might be some trouble if you are not running it under DOS.

People...still...use...that...mode...of...graphics ?

As you can see by my avatar and my signture, I am a DOS programmer. Let me know if you want some help. I use DJGPP 2.03, on Windows 98. I test my programs on a Windows XP Home & Professional. I have a friend that ttests my programs for me. I have a VERY good gra[hics engine, called REDRAW_ENGINE. Actully, my brother made it for me. I use keyboard interrupts, timer interrupts.

I can show you an example program:

Code:

 #include "graphics.h"
 #include "interrupt.h"
 int main() {
	 int x = 0;
	 init_engine(0, 0);
	 init_keyboard();
	 graphics_screen_mode();
	 while(!key_status[KEY_ESC]) {
		 refresh_screen();
		 x++;
		 box(0, 0, 320, 200, x, set);
	 }
	 done_keyboard();
	 return 0;
 }

Referring to graphics mode 13h . . .

All the time.

It works on a certain 66MHz computer.

But back on topic. Here's how you might change a position:

Code:

#define HEIGHT 5
int array[HEIGHT][5];
int *p1 = &array[2][2];
int *p2 = p1;

p1 += HEIGHT;
p2 ++;

/* now p1 points to array[3][2], p2 to array[2][3] */

Be sure to put boundry checking in, too.

DJGPP works just fine for mode 13h. The exes it generates work on WinXP, 98 and 95 (66MHz). Although you have to slow it down a bit on WinXP . . . syncronizing to vertical retrace works really well.

Mode 13h speed is based on the fact that each pixel is one byte. So a complete screen refresh is only 64kb, which even a 386 can do reasonably well.

If you are using DJGPP, might I recommend jumping up to higher screen resolutions using int 10h Vesa BIOS Extensions. This will allow you to access the linear frame buffer, but you CANNOT use the near pointer hack inside of XP, it will fail at all times.

You must use farnpokeb or some other derivative in DJGPP under XP to plot pixels.

Ah..heck, dump DJGPP and use DirectX or OpenGL.

I HATE DIRECTX! I installed it, and it killed the sound on my computer. After 6 months, I finnaly got it back. The video is way to slow, multi-player crashes, and it actully froze my computer when I ran my program. I lose 4MB every time I run a program. I have started with the SDL.
Actully, I use DOS. I have a very good game (if anyone wants it . . . notify me) using DOS. It works on WinXP, Win95, and even Macintosh 84 (Windows 3.1).
So, any other questions????

I thought Macintosh 84 was Windows 95.
