В самом низу добавляем строки, с подписью //ADDED

class FileWeaponInfo_t

Теперь к weapon_parse.cpp
_______________________________________________________________________________________________________
Добавим это:

void FileWeaponInfo_t::Parse( KeyValues *pKeyValuesData, const char *szWeaponName )
{
...
// this just saves off the data in the script file for later use
KeyValues *pEt = pKeyValuesData->FindKey("ExpOffset");

m_expOffset.y = pEt->GetFloat("y", 0.0f);
m_expOffset.z = pEt->GetFloat("z", 0.0f);

m_expOriOffset.x = pEt->GetFloat("xori", 0.0f);
m_expOriOffset.y = pEt->GetFloat("yori", 0.0f);
m_expOriOffset.z = pEt->GetFloat("zori", 0.0f);

Находим строку ViewModel::Spawn и меняем:

Всё.Компилируем.

Теперь к скриптам.Менять будем weapon_pistol.txt

Вписать где-нибудь в скрипт:

ExpOffset
{
"x" "-10"
"y" "-5.34"
"z" "4.25"
// "xori" "-2.9" //Does not work
// "yori" "1.1" //Does not work
// "zori" "2.0" // Does not work
}

Экстра
Это не обязательно.
Если вы считаете скорость передвижения пистолета слишком медленной, то давай не увеличим её!

Ищем эту строку: float gIronsightedTime(0.0f); и дописываем снизу:

float gMoveTime(0.1f); //Seconds to use to move the model up to players view

Теперь топаем до float delta(gpGlobals->curtime - gIronsightedTime); и меняем на float delta((gpGlobals->curtime - gIronsightedTime) / gMoveTime);
