简短的问题描述

我有一个问题，当我更改枚举时，它没有改变。
它看起来只是一个局部变化。

如果我做下面的报价就可以了。

level = new level_1();
while(true)
{
    cout << level->state << endl; // show '1' at first loop. Another loop show '2'
    level->state = STATE_INITIALIZE;
}

但我必须改变他函数的状态

level = new level_1();
while(true)
{
    cout << level->state << endl; // show '1' only
    level.do();
}

level.do 功能

void Level_1::do()
{
    state = STATE_INITIALIZE; // If this work, it should be '2'
    // this->state = STATE_INITIALIZE;
}

所以这对我来说是一个大问题，它不会改变！！T_T

长代码

这是一些代码(几乎是完整的代码(

水平.h

enum LEVEL_STATE
{       STATE_LOAD = 1,
        STATE_INITIALIZE = 2,
        STATE_UPDATE = 3,
        STATE_DRAW = 4,
        STATE_FREE = 5,
        STATE_UNLOAD = 6
};
class Level {
public:
    LEVEL_STATE state = STATE_LOAD;
    vector<Shader> shader;
    vector<Model> model;
    virtual void load()=0;
    virtual void initialize()=0;
    virtual void update()=0;
    virtual void draw(Shader)=0;
    virtual void free()=0;
    virtual void unload()=0;
    virtual Level* next()=0;
};

Map_Level_1.h

#include"Level.h"

    void initialize();
    void update();
    void draw(Shader);
    void free();
    void unload();
    Level* next();
};

Map_Level_1.cpp

void Level_1::unload()

Level* Level_1::next() {
    return new Level_0();

主.cpp

level = new Level_1();
while (!glfwWindowShouldClose(window))
{
    DEV_processInput(window);
    cout << level->state;
    switch (level->state)
    {
    case STATE_LOAD:
        level->load();
    case STATE_INITIALIZE:
        level->initialize();
    case STATE_UPDATE:
        level->update();

    case STATE_UNLOAD:
        level->unload();
    }
    glfwSwapBuffers(window);
    glfwPollEvents();
}

如果我1.(做一些容易解决
的错误2.(重复任何问题

我会道歉的..
