Solved C++ // addSkillAdvance

[rafaeru]

hello i want to create absorb skill instead fishing but:
in:

combatChangeHealth

add:

                if(combatType == COMBAT_ENERGYDAMAGE && target && target->getPlayer())  
                {  
                    double absorbPower2 = 0, damageChange2 = 0;
                    int32_t skillShield2 = target->getPlayer()->getSkill(SKILL_FISH, SKILL_LEVEL); 
                    addSkillAdvance(SKILL_FISH, 1);
                    if(skillShield2 >= 15)  
                    {
                        absorbPower2 = (std::floor(skillShield2 / 5) - 3) * 3; 
                        damageChange2 = std::ceil((damage * absorbPower2) / 100);
                    }                       

                    if((int32_t)damageChange2 != 0)  
                    {  
                        damage -= (int32_t)damageChange2;  
                        char buffer[150];  
                        sprintf(buffer, "%d hitpoint%s has been absorbed by your reiatsu control.", (int32_t)damageChange2, ((int32_t)damageChange2 == 1 ? "" : "s"));  

                        target->getPlayer()->sendTextMessage(MSG_EVENT_DEFAULT, buffer);  
                    }  
                }

here is problem:

addSkillAdvance(SKILL_FISH, 1)

game.cpp:4201:35: error: 'addSkillAdvance' was not declared in this scope
