Simple Cusom Maplist

[Rikku2000]

Here my code for a Simple Custom Maplist for Quake

First we have to define the new menu, add m_maplist after m_gameoptions
in the enum {...}

now we define the menu voids:
void M_Menu_MapList_f (void);
void M_MapList_Draw (void);
void M_MapList_Key (int key);

so at first we have defined all new menus

now an copy&past code add it after "void M_GameOptions_Key (int key)":

Code: Select all

//=============================================================================
/* MAPLIST MENU */

#include <sys/dirent.h>

#define MAX_FILE_LIST 15

int initState = 1;
int numFiles = 0;
int minFile = 0;
int maxFile = MAX_FILE_LIST;
struct dirent **nombres;
char listaFiles[MAX_FILE_LIST][256];
char nombreFile[MAX_FILE_LIST];
int arrowY = 35;
int posArrow = 0;
int numFileList = 0;
int lastArrowY = 0;

void DeleteArray (char listaFiles[MAX_FILE_LIST][256], int numFileList) {
   int i;

   for (i = 0; i < numFileList; i++)
      strcpy(listaFiles[i], "0");
}

void FileNames (char listaFiles[MAX_FILE_LIST][256], int numFileList) {
   int y = 35;
   int i;

   for(i = 0; i < numFileList; i++) {
      M_Print (74, y, listaFiles[i]);

      y += 8;
   }
}

int isFile(const struct dirent *nombre) {
   int isFile = 0;

   char *extension = strrchr(nombre->d_name, '.');

   if (strcmp(extension, ".bsp") == 0)
      isFile = 1;

   return isFile;
}

void M_Menu_MapList_f (void)
{
   key_dest = key_menu;
   m_state = m_maplist;
   m_entersound = true;

   if(initState) {
      numFiles = scandir(va("%s/maps", GAMENAME), &nombres, isFile, alphasort);

      if (numFiles < MAX_FILE_LIST) {
         maxFile = numFiles;
         numFileList = numFiles;
      } else
         numFileList = MAX_FILE_LIST;

      DeleteArray(listaFiles, numFileList);

      int x = 0;
      int i;

      for (i = minFile; i < maxFile; i++){
         strcpy(listaFiles[x], nombres[i]->d_name);
         x++;
      }

      initState = 0;
   }
}

void M_MapList_Draw (void)
{
   qpic_t   *p;
   int      x;

   M_DrawTransPic (16, 4, Draw_CachePic ("gfx/qplaque.lmp") );
   p = Draw_CachePic ("gfx/p_multi.lmp");
   M_DrawPic ( (320-p->width)/2, 4, p);

   M_DrawTextBox (56, 27, 23, 15);
   if (!numFileList) {
      M_PrintWhite (104, 59, "Empty Map list");
      return;
   } else
      FileNames(listaFiles, numFileList);

   M_DrawCharacter (64, arrowY, 12 + ((int)(realtime * 4) & 1));
}

void M_MapList_Key (int key)
{
   switch (key)
   {
   case K_ESCAPE:
      M_Menu_GameOptions_f ();
      break;

   case K_UPARROW:
      S_LocalSound ("misc/menu1.wav");
      arrowY -= 8;
      posArrow--;

      if (posArrow < 0) {
         if (minFile != 0) {
            minFile--;
            maxFile--;

            DeleteArray(listaFiles, numFileList);

            int x = 0;
            int i;

            for (i = minFile; i < maxFile; i++) {
               strcpy(listaFiles[x], nombres[i]->d_name);
               x++;
            }
         }

         arrowY = 35;
         posArrow = 0;
      }
      break;

   case K_DOWNARROW:
      S_LocalSound ("misc/menu1.wav");
      lastArrowY = arrowY;
      arrowY += 8;

      if (posArrow > numFileList-2) {
         if(maxFile+1 <= numFiles) {
            minFile++;
            maxFile++;

            DeleteArray(listaFiles, numFileList);

            int x = 0;
            int i;

            for (i = minFile; i < maxFile; i++) {
               strcpy(listaFiles[x], nombres[i]->d_name);
               x++;
            }
         }

         arrowY = lastArrowY;
      } else
         posArrow++;
      break;

   case K_ENTER:
      S_LocalSound ("misc/menu2.wav");
         strcpy(nombreFile, listaFiles[posArrow]);
         COM_StripExtension (nombreFile, nombreFile);
         COM_StripExtension (nombreFile, nombreFile);
         Cbuf_AddText (va("map %s\n", nombreFile));
         break;
   }
}

now we have to add small code in "M_Init", "M_Draw", "M_Keydown".

"M_Init" add:
Cmd_AddCommand ("menu_maplist", M_Menu_MapList_f);

"M_Draw"
case m_maplist:
M_MapList_Draw ();
break;

"M_Keydown" add:
case m_maplist:
M_MapList_Key (key);
return;

now we have an working Custom maplist.

Thank you Rikku2000 for posting this tutorial! Unfortunately I couldn't find how to make it work
On windows msvc didn't find dirent.h in my sys so I had to download here and redefine it like this

Code: Select all

#include "sys/dirent.h"

and comment the part where it includes <machine/ansi.h>
Anyway I tried to follow all the steps as you wrote but it gave me a lot of errors. Since I use the italian version of MSVC2008 Express I'll try to translate them!

Thanks for this tute. It's a great idea. Got it to work with two changes:
1. changed "strcat" to "strcpy" here- strcpy(nombreFile, listaFiles[posArrow]); Otherwise would add new map name onto the old map name.
2. I use mingw to compile for Windows. Unlike Linux gcc, mingw doesn't come with implementation of scandir, so I pasted in source for it. Don't know if would help MSVC2008 issue

Code: Select all

#include<stdlib.h>
#include<sys/types.h>

//qbism - needed for Rikku2000 maplist, but not included w/ mingw
int scandir(const char *dir, struct dirent ***namelist,
            int (*select)(const struct dirent *),
            int (*compar)(const struct dirent **, const struct dirent **)) {
  DIR *d;
  struct dirent *entry;
  register int i=0;
  size_t entrysize;

  if ((d=opendir(dir)) == NULL)
     return(-1);

  *namelist=NULL;
  while ((entry=readdir(d)) != NULL)
  {
    if (select == NULL || (select != NULL && (*select)(entry)))
    {
      *namelist=(struct dirent **)realloc((void *)(*namelist),
                 (size_t)((i+1)*sizeof(struct dirent *)));
   if (*namelist == NULL) return(-1);
   entrysize=sizeof(struct dirent)-sizeof(entry->d_name)+strlen(entry->d_name)+1;
   (*namelist)[i]=(struct dirent *)malloc(entrysize);
   if ((*namelist)[i] == NULL) return(-1);
   memcpy((*namelist)[i], entry, entrysize);
   i++;
    }
  }
  if (closedir(d)) return(-1);
  if (i == 0) return(-1);
  if (compar != NULL)
    qsort((void *)(*namelist), (size_t)i, sizeof(struct dirent *), compar);

  return(i);
}

int alphasort(const struct dirent **a, const struct dirent **b) {
  return(strcmpi((*a)->d_name, (*b)->d_name));
}


[toneddu2000]

I compiled it under linux too but it gave same errors. Can please someone take a look at the menu.c I posted and tell me if I committed some error?
@qbism: the part of code you write: where should I put it?
Thanks

[qbism]

Put it in menu.c, above void SetSavename () and under #include<dirent.h>
Don't do the other stuff you tried.

Some systems are #include <sys/dirent.h>

[qbism]

edited alphasort in snippit above, return strcmpi (case insensitive) rather than strcmp

[Rikku2000]

I thing MSVC dont handle the crosscompiler. cygwin or mingw can use the same libs and aso the include fieles mingw i a bit faster then cygwin but i perfer it its easy to handle and i use it for wii, gamecube etc too
