Tenho essa funcao nas sources party.cpp. 

Como posso chama-la nas minhas funcoes lua?

Tentei criar um talkaction para chamar setSharedExperience(cid, enable), mas o script nao reconhece.

bool Party::setSharedExperience(Player* player, bool _sharedExpActive)
{
if(!player || getLeader() != player){
return false;
}

if(sharedExpActive == _sharedExpActive){
return true;
}

sharedExpActive = _sharedExpActive;

if(sharedExpActive){
sharedExpEnabled = canEnableSharedExperience();
if(sharedExpEnabled){
getLeader()->sendTextMessage(MSG_INFO_DESCR, "Shared Experience is now active.");
}
else{
getLeader()->sendTextMessage(MSG_INFO_DESCR, "Shared Experience has been activated," \
" but some members of your party are inactive.");
}
}
else{
getLeader()->sendTextMessage(MSG_INFO_DESCR, "Shared Experience has been deactivated.");
}

updateAllPartyIcons();
return true;
}

As funções usadas nos scripts .lua ficam no arquivo luascript.cpp
