Showing new ammovalues on the HUD??

[drm_wayne]

Hey there,

I have recently modded my engine (WinQuake) showing my current used Shotgun clip (STAT_AMMO) and the restammo using STAT_SHELLS...
Its drawn with Sbar_DrawNum and works like a charm...

But now i have a question for some tricky stuff...

I have made many custom ammos using .float ammo_SMG, .float ammo_whatever and so on, and i want them on my hud too...
Can anybody help me how i can do that in the engine?

I made that previously on an older thread (with altammo and recording problem), so here's what you globally have to do:

(I modified some things in order to be a bit "lazyier" for future weapon modifications, but it does work on stock engines)

==============================
ENGINE MODIFICATION
==============================

1) Add a new define for your weapon stat in your Quakedef.h:
(Look that I enumed this, and added Ammo stats at the end in order to modify less things later)

Code: Select all

enum
{
   STAT_HEALTH   = 0,      // HEALTH
   STAT_FRAGS   = 1,         // FRAGS
   STAT_WEAPON = 2,      // CURRENT WEAPON
   STAT_AMMO = 3,         // CURRENT AMMO
   STAT_ARMOR = 4,
   STAT_WEAPONFRAME = 5,
   STAT_ACTIVEWEAPON = 6,
   STAT_TOTALSECRETS = 7,
   STAT_TOTALMONSTERS = 8,
   STAT_SECRETS = 9,
   STAT_MONSTERS = 10,
   STAT_SHELLS = 11,
   STAT_NAILS = 12,
   STAT_ROCKETS = 13,
   STAT_CELLS = 14,
   STAT_NEWAMMO = 15      // --> New Ammo type
};

#define TOTAL_AMMO_STATS  5   // Maximum Ammo Stats available


Also, add too a new IT_NEWAMMO line :

Code: Select all

#define WEAPON_AXE              (1<<0)
#define   IT_SHOTGUN            (1<<1)
#define   IT_SUPER_SHOTGUN      (1<<2)
#define   IT_NAILGUN            (1<<3)
#define   IT_SUPER_NAILGUN      (1<<4)
#define   IT_GRENADE_LAUNCHER      (1<<5)
#define   IT_ROCKET_LAUNCHER      (1<<6)
#define   IT_LIGHTNING         (1<<7)
#define IT_SUPER_LIGHTNING      (1<<8)
#define IT_SHELLS               (1<<9)
#define IT_NAILS                (1<<10)
#define IT_ROCKETS              (1<<11)
#define IT_CELLS                (1<<12)
#define IT_NEWAMMO            (1<<13) // I AM HERE  !
#define IT_ARMOR1               (1<<14)
#define IT_ARMOR2               (1<<15)
#define IT_ARMOR3               (1<<16)
#define IT_SUPERHEALTH          (1<<17)
#define IT_KEY1                 (1<<18)
#define IT_KEY2                 (1<<19)
#define   IT_INVISIBILITY         (1<<20)
#define   IT_INVULNERABILITY      (1<<21)
#define   IT_SUIT               2097152
#define   IT_QUAD               4194304
#define IT_SIGIL1               (1<<28)
#define IT_SIGIL2               (1<<29)
#define IT_SIGIL3               (1<<30)
#define IT_SIGIL4               (1<<31)

==============================
CLIENT SIDE MODIFICATION
==============================

2) in cl_parse.c, search this :

Code: Select all

   for (i=0 ; i<4 ; i++)
   {
      j = MSG_ReadByte ();
      if (cl.stats[STAT_SHELLS+i] != j)
      {
         cl.stats[STAT_SHELLS+i] = j;
         Sbar_Changed ();
      }
   }


And replace it with :

Code: Select all

   for (i=0 ; i<TOTAL_AMMO_STATS ; i++)
   {
      j = MSG_ReadByte ();
      if (cl.stats[STAT_SHELLS+i] != j)
      {
         cl.stats[STAT_SHELLS+i] = j;
         Sbar_Changed ();
      }
   }


============================
SERVER SIDE MODIFICATION
=============================

3) In your Progsdef.q1 , add below

Code: Select all

float   ammo_cells;

this:

Code: Select all

float   ammo_newammo;

4) Do the same on the QuakeC side (with progdefs.h)

5) In void SV_WriteClientdataToMessage (edict_t *ent, sizebuf_t *msg)

Add below

Code: Select all

MSG_WriteByte (msg, ent->v.ammo_cells);

this

Code: Select all

MSG_WriteByte (msg, ent->v.ammo_newammo);

========================
HUD DRAWING
===========================

6) In sbar.c , find

Code: Select all

qpic_t      *sb_ammo[4];

And replace it with :

Code: Select all

qpic_t      *sb_ammo[TOTAL_AMMO_STATS ];

-------------

Find

Code: Select all

   sb_ammo[3] = Draw_PicFromWad ("sb_cells");

and add below

Code: Select all

   sb_ammo[4] = Draw_PicFromWad ("sb_newammo"); // Of course, modify it with your image

-------------

Find

Code: Select all

         else if (cl.items & IT_CELLS)
            Sbar_DrawPic (224, 0, sb_ammo[3]);

And add below

Code: Select all

         else if (cl.items & IT_NEWAMMO)
            Sbar_DrawPic (224, 0, sb_ammo[4]);

======================
QUAKE C MODIFICATION
======================

All you will have to do is to link your ammo_flags with your IT_ and your new STAT_ ... But best is to leave that to you!
Once it is done, careful though. Compile your QC code first, get the new CRC , and paste it to your progdefs.q1 CRC .

There may be errors, I did it without compiling it, but I hope that will help...

[drm_wayne]

thanks, i will test it

look trickier than i thought

sbar.c can be fun to hack! One time I totally ripped off Duke3D's status bar, in a day, with ammo counters for 9 weapons, being lit when selected appropriately.
