[C++]需要帮助建立一个类

我是新的C++，我正在尝试创建一个Mario游戏。我有三个我正在工作的课：舞台，图像和元素。第一个有自己的.h和.cpp，另外两个有另一个.h和.cpp; 问题是：在Stage阶段，我有一些Element类型的变量，我不能为世界上的任何东西声明没有问题。我的代码是： Elements.h[C++]需要帮助建立一个类

现在我的错误得到：image

上移Stage *stage2;出你Elements.h的，或转发申报Elements.h的class Stage无#include "Stage.h"。

你现在做什么，总会出错。

您需要

class Stage;

同样替换下列行Elements.h

Stage * stage2;

在其他文件中也

你想声明一个结构类？（'HDC'） - 请参阅'windef.h' – Blacktempel 2015-04-01 05:19:03

-1

我强烈建议你重温C的语法++。你所有的错误都是由语法错误造成的。例如，第一个可以很容易地通过替换。在之前的3 =块到，此外，更改顺序为blocks = 3等。同时定义全部为ints，并且不要让编译器隐式为您做。

显示的其余错误在mario.cpp中，您没有显示。希望这有助于！

我试着在你的答案上多次阅读，我不知道你想说什么。另外，我看到无处不在的初始化变量。 – Blacktempel 2015-04-01 05:26:30
