[C++] - getStorage, setStorage

[Oskar1121]

Hello,
I have a big problem. I have found in creature.cpp two functions:

bool Creature::getStorage(const uint32_t key, std::string& value) const
{
    StorageMap::const_iterator it = storageMap.find(key);
    if(it != storageMap.end())
    {
        value = it->second;
        return true;
    }

    value = "-1";
    return false;
}

bool Creature::setStorage(const uint32_t key, const std::string& value)
{
    storageMap[key] = value;
    return true;
}

But when I use this function in this way:

target->getAttackedCreature()->getStorage(key, value)

Then the program finds errors

 C:\Users\Oskar\Desktop\0.3.6pl1.r83\creature.cpp In member function `virtual void Creature::onAttackedCreatureKilled(Creature*)': 
1211 C:\Users\Oskar\Desktop\0.3.6pl1.r83\creature.cpp invalid use of member (did you forget the `&' ?) 
1211 C:\Users\Oskar\Desktop\0.3.6pl1.r83\creature.cpp base operand of `->' is not a pointer

My question is: how to use this function in creature.cpp?

not sure what are you doing, but this has compiled fine
[cpp]//
if(getMaster() && getMaster()->getAttackedCreature()) { //This happens if the monster is summoned during combat
std::string val;
if(getMaster()->getAttackedCreature()->getStorage(100, val))
selectTarget(getMaster()->getAttackedCreature());
}[/cpp]

It's getStorage, how to look setStorage?

 

[Cykotitan]

the same way, but 2nd argument is new value for key

I have:

void Creature::onAttackedCreatureKilled(Creature* target)
{
	if(target == this)
		return;

	double gainExp = target->getGainedExperience(this);
	onGainExperience(gainExp, target, false);
	char result[100];
	std::string val;
    sprintf(result, "%f", gainExp);
	target->getAttackedCreature()->setStorage(1000, result);
	std::cout << target->getAttackedCreature()->getStorage(1000, val) << std::endl;
}

But in console still shows number 1. Why? But when i check in LUA storage value then show good value.

[cpp]void Creature:nAttackedCreatureKilled(Creature* target)
{
if(target == this)
return;

double gainExp = target->getGainedExperience(this);
onGainExperience(gainExp, target, false);
std::stringstream s;
s << gainExp;
target->getAttackedCreature()->setStorage(1000, s.str());
std::string val;
target->getAttackedCreature()->getStorage(1000, val);
std::cout << val << std::endl;
}[/cpp]
