А теперь в weapon_iceaxe.h впишем это:

Всё, с серверной частью все хорошо, теперь нам нужно вписать наш ледакол в клинет, так что направляемся сюда (src\cl_dll\hl2_hud\c_weapon__stubs_hl2.cpp) и где то после строчки:

STUB_WEAPON_CLASS( weapon_crowbar, WeaponCrowbar, C_BaseHLBludgeonWeapon );

Впишем эту строчку:

STUB_WEAPON_CLASS( weapon_iceaxe, WeaponIceaxe, C_BaseHLBludgeonWeapon );

Так, теперь надо кое что сделать для нашей второй медленной, но более сильной атаки Для этого зайдите сюда (src\dlls\basebludgeonweapon.cpp) и тут в самом низу файла поменяйте строку:

nHitActivity = bIsSecondary ? ACT_VM_MISSCENTER2 : ACT_VM_MISSCENTER;

на эту:

nHitActivity = ACT_VM_MISSCENTER;

Всё, можно компилить! Теперь зайдем в папку с модом, а потом в папку Scripts и там создадим файл weapon_iceaxe.txt и в него впишем следующие:

// Iceaxe

WeaponData
{
// Weapon data is loaded by both the Game and Client DLLs.
"printname" "IceAxe"
"viewmodel" "models/weapons/v_iceaxe.mdl"
"playermodel" "models/weapons/w_iceaxe.mdl"
"anim_prefix" "crowbar"
"bucket" "0"
"bucket_position" "1"

"clip_size" "-1"
"primary_ammo" "None"
"secondary_ammo" "None"

"weight" "0"
"item_flags" "0"

// Sounds for the weapon. There is a max of 16 sounds per category (i.e. max 16 "single_shot" sounds)
SoundData
{
"single_shot" "Weapon_IceAxe.Single"
"melee_hit" "Weapon_IceAxe.Melee_Hit"
"melee_hit_world" "Weapon_IceAxe.Melee_HitWorld"
}
// Weapon Sprite data is loaded by the Client DLL.
TextureData
{
"weapon"
{
"file" "sprites/w_icons1b"
"x" "0"
"y" "64"
"width" "128"
"height" "64"
}

}

{
"file" "sprites/640hud7"

"height" "24"
}
"ammo2"
{
"file" "sprites/640hud7"
"x" "48"
"y" "72"

}
"crosshair"

"autoaim"
{
"file" "sprites/crosshairs"
"x" "0"
"y" "48"
"width" "24"
"height" "24"
}
}
}

Теперь осталась финешная прямаю, надо дописать звуки к ледаколу. Для этого нам надо зайти сюда (scripts\game_sounds_weapons.txt) и тут после обозначей звуков ломика (crowbar) впишем наши:

// weapon_iceaxe.txt
"Weapon_IceAxe.Single"
{
"channel" "CHAN_WEAPON"
"volume" "1.0"
"soundlevel" "SNDLVL_105dB"
"pitch" "95,100"

"wave" "weapons/iceaxe/iceaxe_swing1.wav"
}

"Weapon_IceAxe.Melee_Hit"
{
"channel" "CHAN_WEAPON"
"volume" "1.0"
"soundlevel" "SNDLVL_105dB"
"pitch" "98,102"

"rndwave"
{
"wave" "impact/bullets/flesh/flesh1.wav"
"wave" "impact/bullets/flesh/flesh2.wav"
"wave" "impact/bullets/flesh/flesh3.wav"
}
}

"Weapon_IceAxe.Melee_HitWorld"
{
"channel" "CHAN_WEAPON"
"volume" "1.0"
"soundlevel" "SNDLVL_105dB"
"pitch" "98,102"

"rndwave"
{
"wave" "weapons/crowbar/crowbar_impact1.wav"
"wave" "weapons/crowbar/crowbar_impact2.wav"
}
}

Сделали? Отлично, теперь нам надо сделать совсем чуть-чуть! Идём сюда (cfg\skill.cfg) и после этих строк:

sk_plr_dmg_crowbar "10"
sk_npc_dmg_crowbar "5"

Впишем эти:

sk_plr_dmg_iceaxe "10"
sk_npc_dmg_iceaxe "5"

Всё, заходим в игру и радуемя жизни! Модели к туториалу качать здесь или взять из Миссинг Инфо.
