C++ Attack Speed Skill (tfs 1.4)

[Demolka]

Hello everybody, i found this code on Otland.net. I need some C++ script for Attack Speed Skill. Standard speed=2000ms, 1 axe skill = -10ms
190 AXE = 100ms attack, something like this. I know in tfs 1.4+ a lot of things was changed. Here is that code, i need guys.

uint32_t Player::getAttackSpeed() const
{
    return std::ceil(((weapon && weapon->getAttackSpeed() != 0) ? weapon->getAttackSpeed() * (1 - (getSkill(SKILL_AXE, SKILL_LEVEL) * 10)) : (vocation->getAttackSpeed() / std::max((size_t)1, getWeapons().size()) * (1 - (getSkill(SKILL_AXE, SKILL_LEVEL) * 10)))));
}
}

I get errors:

I think getSkill is not more getSkill but getSkillLevel() in new tfs but i dont understand that shit.
Can someone help/explain it! Thanks guys! Have a nice day!
