    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");

    			xl++;
    			draw(mapf);
    			printf("right");
    			break;

    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)

    While I don't see rewind used in their program, here's what it does:

    The rewind function sets the file position indicator for
    the stream pointed to by stream to the beginning of the
    file. It is equivalent to:

    (void)fseek(stream, 0L, SEEK_SET)

    except that the error indicator for the stream is also
    cleared (see clearerr(3)).

    Hope is the first step on the road to disappointment.
