C++ （对象）未在此范围内声明m_cPoint

我提出了一个课堂观点和一个课堂角色。然后我在我的角色类中将点用作对象。在我的character类中，我想在函数“moveCharacter”中设置point对象，但编译器给出了错误：

character.cpp: In function 'void moveCharacter(double, double, double)':
character.cpp:17:2: error: 'm_cPoint' was not declared in this scope
  m_cPoint.setPoint(dX, dY, dZ);
  ^

h点：

#ifndef POINT_H
#define POINT_H

#include <iostream>

class Point
{
    public:

        Point(const double dX, const double dY, const double dZ);

        double getX() const { return this->m_dX; }
        double getY() const { return this->m_dY; }
        double getZ() const { return this->m_dZ; }

        void setPoint(const double dX, const double dY, const double dZ);

        friend std::ostream& operator<<(std::ostream &out, const Point &cPoint); 

    private:

        double m_dX, m_dY, m_dZ;

};

#endif

#如果不确定点(H)
#定义点
#包括
类点
{
公众：
点（常数双dX、常数双dY、常数双dZ）；
double getX（）常量{返回this->m_dX；}
double getY（）常量{返回this->m_dY；}
double getZ（）常量{返回this->m_dZ；}
无效设定点（常数双dX、常数双dY、常数双dZ）；
friend std:：ostream和操作员更改

到

这就是类成员变量的范围，而不是一个独立的函数
，并且可能修复
这个->m_cPoint.settpoint（dX，dY，dZ）
？哦，天哪……有时候怎么可能监督最简单的事情呢？谢谢！你不需要
这个->
