Cya*_*ime 2 c++ circular-dependency include
好的,这就是我的错误:'Enemy'未在此范围内声明.错误在map.h文件中,即使map.h包含enemy.h,如图所示
#ifndef MAP_H_INCLUDED
#define MAP_H_INCLUDED
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include "enemy.h"
#define MAX_TILE_TYPES 20
using namespace std;
class Map{
public:
Map();
void loadFile(string filename);
int** tile;
int** ftile;
bool solid[MAX_TILE_TYPES];
int width;
int height;
int tileSize;
vector<Enemy> enemies;
};
#endif // MAP_H_INCLUDED

这是敌人
#ifndef ENEMY_H_INCLUDED
#define ENEMY_H_INCLUDED
#include "global.h"
#include "map.h"
class Enemy{
public:
Enemy();
Enemy(float nx, float ny, float nstate);
void update(Map lv);
bool rectangleIntersects(float rect1x, float rect1y, float rect1w, float rect1h, float rect2x, float rect2y, float rect2w, float rect2h);

有谁知道发生了什么以及如何解决它?
enemy.h
包括 map.h
但是,map.h
包括enemy.h
所以,如果你包括enemy.h
,处理将是这样的:
修复此问题,#include "map.h"
从enemy.h
远程声明中删除并替换它,class Map;
你还需要修改void update(const Map& lv);
- 使用const&
并包括"map.h" enemy.cpp
