Console game

[zeid]

Well to remove the flickering I had to include windows.h

and here is the code related;

Code: Select all

LockWindowUpdate(GetConsoleWindow()); //disables drawing in the command console (freezing it so that you don't see the clearing of the screen)
system("cls");//Clear the console
//Do all your drawing/rendering/text
LockWindowUpdate(NULL);//re-enables drawing in the command console

dug through old stuff. i think i found this on the web at some time.
should be relativly fast as it uses a buffer.

this is just an example that makes a yellow X move in a circle on in the console. 100FPS.

as you will note this is limited to windows.

Code: Select all

#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <math.h>

#define SCREEN_WIDTH 80
#define SCREEN_HEIGHT 25

int main( void )
{
	int x = 20;
	int y = 10;
	float ang = 0;
	float rad = 6;

	HANDLE hOutput = (HANDLE)GetStdHandle( STD_OUTPUT_HANDLE );
	COORD dwBufferSize = { SCREEN_WIDTH,SCREEN_HEIGHT };
	COORD dwBufferCoord = { 0, 0 };
	SMALL_RECT rcRegion = { 0, 0, SCREEN_WIDTH-1, SCREEN_HEIGHT-1 };

	CHAR_INFO buffer[SCREEN_HEIGHT][SCREEN_WIDTH];

	ReadConsoleOutput( hOutput, (CHAR_INFO *)buffer, dwBufferSize,
	dwBufferCoord, &rcRegion );

	while(1)
	{
		ang += 0.1;
		buffer[y+(int)(rad*sin(ang))][x+(int)(rad*cos(ang))].Char.AsciiChar = 'X';
		buffer[y+(int)(rad*sin(ang))][x+(int)(rad*cos(ang))].Attributes = 0x0E;
		WriteConsoleOutput( hOutput, (CHAR_INFO *)buffer, dwBufferSize,dwBufferCoord, &rcRegion );
		Sleep(10);

		buffer[y+(int)(rad*sin(ang))][x+(int)(rad*cos(ang))].Char.AsciiChar = ' ';
		WriteConsoleOutput( hOutput, (CHAR_INFO *)buffer, dwBufferSize,dwBufferCoord, &rcRegion );
	}

	return 0;
}

interesting, guess ill have to dig in the windows api for a bit. thank you.

yeah its quite impressive. i wouldn't be surprised tho if all it was is an actual 3d demo that was just converted to ascii art.

I'm pretty sure it is, there are textures in the folder that come with it. It's still a pretty good conversion and rendering engine though.

Yes, he is just converting it to ascii. If you are interested his notes are here.
