Thread: Problems with sluggishnesgsd or something :D

i making somekind of roguegame or something i dunno... and im having problems with the moving... refreshrate is like **** and i have no idea how to make it better

ofcourse general tips are also wellcome

heres my code >> plus the file u need is attached

Code:

#include <stdio.h>
#include <conio.h>

char map;
int x=1,xl,yl;
int def,grass,wall,character,door;
int quit,input;
int line=1;

int draw(FILE *mapf)
{
	clrscr();
	rewind(mapf);
	while(feof(mapf)==0)
	{
		map=fgetc(mapf);
		switch(map)
		{
			case '#':
			textcolor(wall);
			break;
			case '\n':
			while(x!=0)
			{
				printf("\b");
				x--;
			}
			line++;
			break;
			case '.':
			if(line==yl && x==xl-1)
			{
				textcolor(character);
				printf("\b");
				cprintf("@");
				textcolor(def);
			}
			textcolor(grass);
			break;
			case '/':
			textcolor(door);
			break;
			default:
			textcolor(def);
			break;
		}
		cprintf("%c",map);
		x++;
	}
	line=0;
	x=0;
}

int setup(FILE *ini)
{
	fscanf(ini,"DEFAULT=%d\n",&def);
	fscanf(ini,"X LOCATION=%d\n",&xl);
	fscanf(ini,"Y LOCATION=%d\n",&yl);
	fscanf(ini,"GRASS=%d\n",&grass);
	fscanf(ini,"WALL=%d\n",&wall);
	fscanf(ini,"CHAR=%d\n",&character);
	fscanf(ini,"DOOR=%d\n",&door);
}

int main()
{
	clrscr();
	FILE *ini, *mapf;
	mapf=fopen("map.m", "r");
	ini=fopen("map.ini","r");
	if(!mapf||!ini) return 1;
	while(quit!=-1)
	{
		setup(ini);
		draw(mapf);
		input=getch();
		switch(input)
		{
			case 32:
			quit=-1;
			textcolor(LIGHTGRAY);
			textbackground(BLACK);
			break;
			case 56: // up
			yl--;
			draw(mapf);
			printf("up");
			break;
			case 50: // down
			yl++;
			draw(mapf);
			printf("down");
			break;
			case 52: // left
			xl--;
			draw(mapf);
			printf("left");
			break;
			case 54: // right
			xl++;
			draw(mapf);
			printf("right");
			break;
			default:
			draw(mapf);
			break;
		}
	}
	fclose(ini);
	fclose(mapf);
	return 0;
}

What's the rewind function do?

Store the map in an array, not a file

files are like 1000 times slower

Start with
char map[25][80];


Then read your "map.m" file into this array just once at the start

Then recode your draw() function to use this array

You also read your ini file every time around the loop as well (or at least you try to)

ah, thanks!
