Question

我遇到了一些问题，我正在尝试让这个问题起作用，但是我在使用String获取名称时遇到了一些问题。

我收到以下错误：非静态成员引用必须与特定对象相关在

std::string GetName(uint32 entry) //this is the error causer.
    {
        return sObjectMgr->GetItemTemplate(entry)->Name1;
    };

然而，Getname函数在每个其他类

上给我一个错误

#include "Creature.h"
#include "ScriptedCreature.h"
#include "ScriptedGossip.h"
#include "ObjectMgr.h"
#include "Player.h"
