C ++ RPG错误：不允许使用数据成员初始值设定项

Question

已经多次发布，但没有一次能够回答我的情况。请帮助我解决我的错误：不允许使用数据成员初始化程序＆＃39;出现在等号下面。这是包含问题的代码。

//Player.cpp :Contains information about the player
#include <iostream>
#include <string>
#include "Main.cpp"
using namespace std;

void Player()
{
struct Player {
int Charma = 0;
unsigned int Hunger = 10;
unsigned int Energy = 50;
unsigned int Health = 100;
};
enum Race {
UNKNOWN,
DEAD,
HUMAN,
ORC,
GOBLIN,
ELF,
LIZARD,
CAT,
VAMPIRE,
WEREWOLF,
SNK
};
}

Answer 1

您收到该错误是因为您在声明struct时正在初始化变量。这是不允许的。而是将初始化移动到struct的构造函数中。

但是，这不是代码中唯一的错误。您正在定义struct函数内部的Player（应该是构造函数）。您需要切换它们，以便Player结构中包含Player函数。这样结构将有一个构造函数，您可以在其中初始化值。另一件事，不要#include .cpp文件。这是一种不好的做法。

您的代码应该是这样的：

struct Player {
int Charma;
unsigned int Hunger;
unsigned int Energy;
unsigned int Health;

   Player() : Charma(0), Hunger(10), Energy(50), Health(100)
   {
      // do other constructor stuff here
   }
};

Answer 2

另一种想法是，如果你打算在Player内部进行一些机械操作，你可以将声明移到真实的class中。然后，您将能够更轻松地扩展项目。像这样：

标题

// #include "Item.h"

typedef enum RaceDef {
    UNKNOWN,
    DEAD,
    HUMAN,
    ORC,
    GOBLIN,
    ELF,
    LIZARD,
    CAT,
    VAMPIRE,
    WEREWOLF,
    SNK
} PlayerRace;

class Player {
public:
   Player(unsigned int Charma=0,
          unsigned int Hunger=10,
          unsigned int Energy=50,
          unsigned int Health=100,
          PlayerRace Race=HUMAN);

   void attack(Player);
   void slap(Player);
   //void equipItem(Item);
   void exercise(unsigned int duration);
   void die();
   void etc();

private:
   unsigned int m_Charma;
   unsigned int m_Hunger;
   unsigned int m_Energy;
   unsigned int m_Health;
   unsigned PlayerRace m_Race;

   Race m_Race;
};

<强> CPP

Player::Player(unsigned int Charma,
               unsigned int Hunger,
               unsigned int Energy,
               unsigned int Health,
               PlayerRace Race):
m_Charma(Charma),
m_Hunger(Hunger),
m_Energy(Energy),
m_Health(Health),
m_Race(Race) {
    //constructor code goes here
    //e.g. if player starts with a random item :
    //   Item randomItem = ItemUtils.getRandomItem();
    //   equipItem(randomItem);
}

我希望这会有所帮助，祝你好运:)。
