[TUT] How to add p_, w_ models for grenades for zp 4.3

Hellow members and staff.

today i'm gonna show how to add "P_, W_, models" on zp 4.3, ok let's start!

1.First we locking for : 

model_grenade_fire[64], model_grenade_frost[64], model_grenade_flare[64],
 and we need to add before this cvars :


model_grenade_fire_p[64], model_grenade_frost_p[64], model_grenade_flare_p[64], model_grenade_infect_p[64],
model_grenade_fire_w[64], model_grenade_frost_w[64], model_grenade_flare_w[64], model_grenade_infect_w[64],
2.Next we are looking for: // Custom weapon models


engfunc(EngFunc_PrecacheModel, model_grenade_fire)
engfunc(EngFunc_PrecacheModel, model_grenade_frost)
engfunc(EngFunc_PrecacheModel, model_grenade_flare)
and we need add after that models :

engfunc(EngFunc_PrecacheModel, model_grenade_fire_p)
engfunc(EngFunc_PrecacheModel, model_grenade_frost_p)
engfunc(EngFunc_PrecacheModel, model_grenade_flare_p)
engfunc(EngFunc_PrecacheModel, model_grenade_infect_p)
engfunc(EngFunc_PrecacheModel, model_grenade_fire_w)
engfunc(EngFunc_PrecacheModel, model_grenade_frost_w)
engfunc(EngFunc_PrecacheModel, model_grenade_flare_w)
engfunc(EngFunc_PrecacheModel, model_grenade_infect_w)
3.Next we are looking for: // Forward Set Model

// Forward Set Model
public fw_SetModel(entity, const model[])
{
// We don't care
if (strlen(model) < 8)
return;

// Remove weapons?
if (get_pcvar_float(cvar_removedropped) > 0.0)
{
// Get entity's classname
static classname[10]
pev(entity, pev_classname, classname, charsmax(classname))

// Check if it's a weapon box
if (equal(classname, "weaponbox"))
{
// They get automatically removed when thinking
set_pev(entity, pev_nextthink, get_gametime() + get_pcvar_float(cvar_removedropped))
return;
}
}

// Narrow down our matches a bit
if (model[7] != 'w' || model[8] != '_')
return;

// Get damage time of grenade

}

}
4.Next we are looking for: case CSW_HEGRENADE: // Infection bomb or fire grenade


case CSW_HEGRENADE: // Infection bomb or fire grenade
{
if (g_zombie[id])
set_pev(id, pev_viewmodel2, model_grenade_infect)

}

we need change it to : 


case CSW_HEGRENADE: // Infection bomb or fire grenade
{
if (g_zombie[id])
{
set_pev(id, pev_viewmodel2, model_grenade_infect)
set_pev(id, pev_weaponmodel2, model_grenade_infect_p)
}
else

case CSW_FLASHBANG: // Frost grenade

set_pev(id, pev_viewmodel2, model_grenade_frost)
set_pev(id, pev_weaponmodel2, model_grenade_frost_p)
}
case CSW_SMOKEGRENADE: // Flare grenade
{
set_pev(id, pev_viewmodel2, model_grenade_flare)
set_pev(id, pev_weaponmodel2, model_grenade_flare_p)
}
NOTE : if you got any error replay me here.
5.Next we locking for: //case SECTION_WEAPON_MODELS
we  add this

else if (equal(key, "GRENADE FIRE_P"))
copy(model_grenade_fire_p, charsmax(model_grenade_fire_p), value)
else if (equal(key, "GRENADE FROST_P"))
copy(model_grenade_frost_p, charsmax(model_grenade_frost_p), value)
else if (equal(key, "GRENADE FLARE_P"))
copy(model_grenade_flare_p, charsmax(model_grenade_flare_p), value)
else if (equal(key, "GRENADE INFECT_P"))
copy(model_grenade_infect_p, charsmax(model_grenade_infect_p), value)
else if (equal(key, "GRENADE FIRE_W"))
copy(model_grenade_fire_w, charsmax(model_grenade_fire_w), value)
else if (equal(key, "GRENADE FROST_W"))
copy(model_grenade_frost_w, charsmax(model_grenade_frost_w), value)
else if (equal(key, "GRENADE FLARE_W"))
copy(model_grenade_flare_w, charsmax(model_grenade_flare_w), value)
else if (equal(key, "GRENADE INFECT_W"))
copy(model_grenade_infect_w, charsmax(model_grenade_infect_w), value)
6.Final step : we need add this in "zombieplague.ini"

GRENADE INFECT_P = models/zombie_plague/p_infect.mdl
GRENADE FIRE_P = models/zombie_plague/p_fire.mdl
GRENADE FROST_P = models/zombie_plague/p_fros.mdl
GRENADE FLARE_P = models/zombie_plague/p_flare.mdl
GRENADE INFECT_W = models/zombie_plague/w_infect.mdl
GRENADE FIRE_W = models/zombie_plague/w_fire.mdl
GRENADE FROST_W = models/zombie_plague/w_frost.mdl
GRENADE FLARE_W = models/zombie_plague/w_flare.mdl

 i hope this Tutorial help enjoy!
