warning: comparison between signed and unsigned integer expressions (help)

[Powers]

Hi, I wrote this little code, and when compiling an error occurs...

Player* playerNow = getPlayer();
              uint32_t storageId = g_config.getNumber(ConfigManager::PLAYER_BATTLE_STORAGE);
              std::string value;
              std::string value2;
              
                 if (targetPlayer->getStorageValue(storageId, value) && atoi(value.c_str()) == playerNow->getGUID() && getStorageValue(storageId, value2) && atoi(value2.c_str()) == targetPlayer->getGUID())                                    

                    return;

Error:

player.cpp: In member function 'virtual void Player:nAttackedCreature(Creature*)':
player.cpp:3555: warning: comparison between signed and unsigned integer expressions

why this is happening?

dump?

Player* playerNow = getPlayer();
	uint32_t storageId = g_config.getNumber(ConfigManager::PLAYER_BATTLE_STORAGE);
	std::string value, value2;
	if(targetPlayer->getStorageValue(storageId, value) && atoi(value.c_str()) == (int)playerNow->getGUID() && getStorageValue(storageId, value2) && atoi(value2.c_str()) == (int)targetPlayer->getGUID())                                    
		return;

also its not an error, its just a warning, u can ignore it

Its mean that you are trying to collate uint and int values.
