Add A New Ammo Type

Add A New Ammo Type

Before starting for an example I used extraammo.

Open up Wl_def.h and goto around line 141.

You should see this: #define STARTAMMO 8

Below that add this:

#define STARTEXTRAAMMO 8

Now search for this: gamestate structure.

Once there under int ammo add this:

int extraammo;

Then scroll down to till you see this: Wl_agent.c Defenitions.

When there look for this: void GiveAmmo (int ammo);

Add this below that:

void DrawExtraAmmo (void);
void GiveExtraAmmo (int extraammo);

Now open up Wl_agent.c

Look for this:

void DrawWeapon (void);
void GiveWeapon (int weapon);
void GiveAmmo (int ammo);

It is around line 80 to 90.

Below that add this:
void GiveExtraAmmo (int extraammo);

Now scroll down till you see this:

void DrawAmmo (void)
{
LatchNumber (27,16,2,gamestate.ammo);
}

Below that add this:
void DrawExtraAmmo (void)
{
LatchNumber (27,16,3,gamestate.extraammo);
}

Also above change the 2 to a 3 on the first ammo type otherwise there will be a glitch.

Now keep scrolling down till you see this:
void GiveAmmo (int ammo)
{
if (!gamestate.ammo)    // knife was out
{
  if (!gamestate.attackframe)
  {
   gamestate.weapon = gamestate.chosenweapon;
   DrawWeapon ();
  }
}
gamestate.ammo += ammo;
if (gamestate.ammo > 99)
  gamestate.ammo = 99;
  if (gamestate.chosenweapon <=wp_chaingun)
DrawAmmo ();
}

Below that add this:

void GiveExtraAmmo (int extraammo)
{
if (!gamestate.extraammo)    // knife was out
{
  if (!gamestate.attackframe)
  {
   gamestate.weapon = gamestate.chosenweapon;
   DrawWeapon ();
  }
}
gamestate.extraammo += extraammo;
if (gamestate.extraammo > 150)
  gamestate.extraammo = 150;
if (gamestate.chosenweapon <=wp_new1)
DrawExtraAmmo ();
}

Also if didn't notice this: if (gamestate.chosenweapon <=wp_new1)

This is just an example wp_new1. You can use the machine gun or which ever weapon you want.

Now Search for this: change frame and fire.

Now under case-1 modify the whole thing to this:

ob->state = &s_player;

if (!gamestate.ammo && gamestate.weapon < wp_new1
|| !gamestate.extraammo && gamestate.weapon >= wp_new1)

   {
    gamestate.weapon = wp_knife;
    gamestate.chosenweapon = wp_knife;
    DrawWeapon ();
   }
   else
   {
    if (gamestate.weapon != gamestate.chosenweapon)
    {
     gamestate.weapon = gamestate.chosenweapon;
     DrawWeapon ();
    }
   };
   gamestate.attackframe = gamestate.weaponframe = 0;
   return;

Not far below it is case1:

Modify the whole thing to this:

if (!gamestate.ammo && gamestate.weapon <= wp_chaingun
   || !gamestate.extraammo && gamestate.weapon == wp_new1)
     {
   gamestate.attackframe++;
   break;
   }
   GunAttack (ob);
   if (gamestate.chosenweapon <= wp_chaingun)
   {
   gamestate.ammo--;
   DrawAmmo();
   }
   if (gamestate.chosenweapon == wp_new1)
   {
   gamestate.extraammo--;
   DrawExtraAmmo();
   break;

Now open up Wl_main.c

Search for this: gamestate.ammo = STARTAMMO;

Add this below that: gamestate.extraammo = STARTEXTRAAMMO;

Well thats it for this tutorial big enough for ya?
