Adding a getConditionParamValue(), rlly close

[DemShion]

Hi, so i wanna add a function that returns the value of a condition param[getConditionParamValue()], so i can use it to define a variable on the file game.cpp, for example.
int wathever2 = player->getConditionParamValue(CONDITIONPARAM_SKILL_FISHINGPERCENT);

so yeah... so far ive managed to create the funcion and dont get compiling errors, but something is wrong because when i run the server i get this error:


on the source so far ive modified and added the following:

--------On creature.cpp

//below
bool Creature::isSuppress(ConditionType_t type) const
{
	return ((getConditionSuppressions() & (uint32_t)type) == (uint32_t)type);
}

//added

Condition* Creature::getConditionParam(ConditionParam_t param, int32_t value/* = 0*/ ) const
{
	for(ConditionParamList::const_iterator it = conditionParams.begin(); it != conditionParams.end(); ++it)
	{
		if((*it)->getParam() == param)
			return *it;
	}

	return NULL;
}

int32_t Creature::getConditionParamValue(ConditionParam_t param, int32_t value/* = 0*/)
{
	for(ConditionParamList::iterator it = conditionParams.begin(); it != conditionParams.end(); ++it)
	{
		if((*it)->getParam() != param)
			continue;

		if((*it)->getParam() == param)
			paramValue = value;
			return paramValue;
	}
	
	return NULL;
}

--------On creature.h

//below
		virtual bool isSuppress(ConditionType_t type) const;

//added
		Condition* getConditionParam(ConditionParam_t param, int32_t value = 0) const;
		int32_t getConditionParamValue(ConditionParam_t param, int32_t value = 0);

//below
		ConditionList conditions;

//added
		int32_t paramValue;
		conditionParams;

--------On condition.h

//below
		ConditionType_t getType() const {return conditionType;}

//added
		ConditionParam_t getParam() const {return conditionParam;}

//below
		ConditionType_t conditionType;

//added
		ConditionParam_t conditionParam;

Thats everything ive modified so far, please help me i dont know what to do D:
