[C ++]需要帮助设置课程

标签： c++ class

我是C ++的新手，我正在尝试创建一个Mario游戏。 我正在进行三个课程：舞台，图像和元素。第一个有自己的.h和.cpp，另外两个有.h和.cpp; 问题是：在类Stage中，我有一些Element类型的变量，我无法对世界上任何事情进行声明而没有任何问题。 我的代码是： Elements.h 

#ifndef ELEMENTS_H
#define ELEMENTS_H

#include <stdio.h>
#include <conio.h>
#include <windows.h>

#include "Stage.h"

HDC * mywindow;
Stage * stage2;

class Image{
public:
    bool ontop;
    FILE* entry;
    int lenght, height;
    COLORREF matrix[32][32];
    void load();
    void print(int x, int y, int orientation, int ratiox, int ratioy);
    void erase(int x, int y, int orientation, int ratiox, int ratioy);
private:
};
**strong text**

class Element{
public:
    Element();
    int num, sizex, sizey, orientation, timeofdeath;
    float vely;
    int top, left, spent;
    void print();
    void erase();
    int bottom();
    int right();
    int middlex();
    int middley();

现在出现错误：image

谢谢大家

3 个答案:

答案 0 :(得分：0)

将Stage *stage2;移出您的Elements.h，或者转发class Stage Elements.h，#include "Stage.h"。

您目前所做的事情始终是错误的。

答案 1 :(得分：0)

您需要在Elements.h中替换以下行

Stage * stage2;

与

class Stage;

同样在其他文件中

答案 2 :(得分：-1)

我强烈建议您重温C ++的语法。您遇到的所有错误都是由语法错误引起的。 例如，第一个可以通过替换第一个来轻松处理。在3 =块到a之前， 另外，将顺序更改为blocks = 3等。同时将all定义为ints，并且不要让编译器隐式为您执行此操作。

显示的其余错误位于mario.cpp中，您尚未显示。 希望这有帮助！
