TFS 0.3 (8.20) "magicDamage"

[Drooms]

Hello, please if someone can improve on the script (It would be asked to increase the damage of the magic, set separately for each profession in vocations.xml) took the script from another source but does not work on TFS 0.3 and 0.2 (

I do this:
in vocation.cpp
under:

if(readXMLInteger(p,"fromvoc", intVal))
voc->fromVocation = intVal;

add:

if(readXMLInteger(p, "magicDamage", intVal))
voc->magicDamage = intVal;

under:

fromVocation = 0;

add:

magicDamage = 100;

in vocation.h
under:

uint32_t getFromVocation() const {return fromVocation;}

add:

uint32_t getMagicDamage() const {return magicDamage;}

in combat.cpp

case FORMULA_LEVELMAGIC:
{
max = (int32_t)((player->getLevel() * 1.5 + player->getMagicLevel() * 4) * 1. * mina + minb);
min = (int32_t)((player->getLevel() * 1.5 + player->getMagicLevel() * 4) * 1. * maxa + maxb);
	return true;
break;
}

change to:

case FORMULA_LEVELMAGIC:
	{
max = (int32_t)((player->getLevel() * 1.5 + player->getMagicLevel() * 4) * player->vocation->getMagicDamage() * 0.01 * 1. * mina + minb);
min = (int32_t)((player->getLevel() * 1.5 + player->getMagicLevel() * 4) * player->vocation->getMagicDamage() * 0.01 * 1. * maxa + maxb);
break;
}

compiles and when the error in the console:

 C:\Dev-Cpp\0.3\source\combat.cpp In member function `bool Combat::getMinMaxValues(Creature*, Creature*, int32_t&, int32_t&) const':
