AIUTO!Problema con lettura dei metodi da parte di un vettore

Ciao a tutti! non riesco a capire perché il vettore _atk definito nella classe Monster non legge i metodi che ho definito nella classe Attacks. Qualcuno mi può aiutare?


Attacks::Attacks(int ID): _ID(ID)
{
}

Attacks::Attacks(const Attacks & to_copy){
this->_ID=to_copy.ID();
this->_name=to_copy.name();
this->_PDB=to_copy.PDB();
this->_MSFA[0]=to_copy.MSFA0();
this->_MSFA[1]=to_copy.MSFA1();
this->_MSFA[2]=to_copy.MSFA2();
this->_MSFD[0]=to_copy.MSFD0();
this->_MSFD[1]=to_copy.MSFD1();
this->_MSFD[2]=to_copy.MSFD2();
}


Attacks:: Attacks(string line_entry){

stringstream ss(line_entry);
ss>> _ID>> _name>> _PDB;


for(unsigned int i=0; i< line_entry.size(); ++i){
int j;
if(line_entry.find("attaccante")!= string::npos){
if(line_entry.find("PA")!= string::npos){
j=0;
}
else if(line_entry.find("PD")!= string::npos){
j=1;
}
else if(line_entry.find("PV")!= string::npos){
j=2;
}

if(line_entry.find("-")!= string::npos){
_MSFA[j]=-1;
if(line_entry.find("-")!= string::npos){
_MSFA[j]--;
ss>>_MSFA[0]>>_MSFA[1]>>_MSFA[2];
}
else ss>>_MSFA[0]>>_MSFA[1]>>_MSFA[2];
}

else if(line_entry.find("+")!= string::npos){ // npos significa -1
_MSFA[j]=1;
if(line_entry.find("+")!= string::npos){
_MSFA[j]++;
ss>>_MSFA[0]>>_MSFA[1]>>_MSFA[2];
}
else ss>>_MSFA[0]>>_MSFA[1]>>_MSFA[2];
}
}


if(line_entry.find("difensore")!= string::npos){

if(line_entry.find("PA")!= string::npos){
j=0;
}
else if(line_entry.find("PD")!= string::npos){

}
else if(line_entry.find("PV")!= string::npos){

}
}

if(line_entry.find("p")!= string::npos){
_priority=true;

}
ss>>_priority;
}
}
