Feature Creatureevent OnGainExp

[foxkbt]

my gain experience its not the same

bool Player::gainExperience(double& gainExp, bool fromMonster)

i change all function to that

bool Player::gainExperience(double& gainExp, bool fromMonster)
{
     if(!rateExperience(gainExp, fromMonster))
   		return false;
          bool deny = false;
		CreatureEventList gainExpEvents = this->getCreatureEvents(CREATURE_EVENT_GAINEXP);
		for(CreatureEventList::iterator it = gainExpEvents.begin(); it != gainExpEvents.end(); ++it)
		{
			if(!(*it)->executeGainExp(this, gainExp))
				deny = true;
		}
		if(deny)
        return false; 
     
     addExperience((uint64_t)gainExp);
     return true;
}

and i have this error

 C:\Users\Bruna\Documents\fox\soucers - Cópia\player.cpp In member function `bool Player::gainExperience(double&, bool)': 
3665 C:\Users\Bruna\Documents\fox\soucers - Cópia\player.cpp [Warning] passing `double' for converting 2 of `uint32_t CreatureEvent::executeGainExp(Player*, int32_t)'

ps:I removed the condition of the soul, because I need this does not work on my server


@Edit-
i try remove the "this->" but is the same shit

@Edit-2
i try change to that
and i not have compilation error

bool Player::gainExperience(double& gainExp, bool fromMonster)
{
     if(!rateExperience(gainExp, fromMonster))
   		return false;
     //if(gainExp >= 1)
    // {
        bool deny = false;
		CreatureEventList gainExpEvents = getCreatureEvents(CREATURE_EVENT_GAINEXP);
		for(CreatureEventList::iterator it = gainExpEvents.begin(); it != gainExpEvents.end(); ++it)
		{
			if(!(*it)->executeGainExp(this,gainExp))
				deny = true;
		}
		if(deny)
                return false;
        
        addExperience((uint64_t)gainExp);
        return true;
    // }
}

Edit-3
When i try to compile with Ctrl-f11 give me the same error!
