Question

我还没有真正更改我的代码，突然之间无法再编译这个错误：

缺少标识符和语法; befor *出现在蛇文件里面，这是：

#pragma once

#include "GameBase.h"
#include <list>

using namespace std;
enum State
{
    POSX, NEGX, POSY, NEGY, POSZ, NEGZ
};

enum ChangeState
{
    RIGHT, LEFT, UP, DOWN
};

class Snake : public Actor
{
public:
    Snake(GameBase *game, Config *config); // HERE theidentifier
    ~Snake();

    //interface methods
    void update(float delta);
    void render(ID3D11DeviceContext *context, ID3D11Buffer *worldBuffer);

    void setState(ChangeState& state);
private:
    /*Containing the pointer to the cubes of the snake*/
    list<Cube *> m_cubes;
    GameBase *m_game; // here the syntax ; before *
    //timer for updating
    float m_updateTime;
    float m_timer;
    int m_cubeSize = 21;

    State m_state;
};

最后但并非最不重要的是游戏基地：

#pragma once

#include "Dx11Base.h"
#include "Cube.h"
#include "Wall.h"
#include "Group.h"
#include "Camera.h"
#include "Logger.h"
#include "InputHandler.h"
#include "Snake.h"

#include <vector>
class GameBase : public Dx11Base
{
public:
    GameBase();
    virtual ~GameBase();
    /*load all shader and so on*/
    bool load();
    /*unload to be save when changing*/
    void unload();
    /*update the gamestate */
    void update(float delta);
    /*presents the new game state*/
    void render();
    /*Callback for the window its size changes*/
    void callBack();
    //set vscync or not
    void setVsync(bool b);

    void addToGroup(Actor* a);

    int m_world[21][21][21];

private:
    ID3D11VertexShader* m_vertexShader;
    ID3D11PixelShader* m_pixelShader;

    ID3D11InputLayout* m_inputLayout;

    ID3D11BlendState* m_alphaBlendState; // generel blend state

    ID3D11Buffer* m_viewCB; //constant buffer for view matrix
    ID3D11Buffer* m_projCB; //constant buffer for view matrix
    ID3D11Buffer* m_worldCB; //constant buffer for view matrix
    ID3D11Buffer* m_cameraPosCB; //constant buffer for view matrix

    XMMATRIX m_projectionMatrix; // viewport matrix

    Camera m_camera;
    InputHandler m_input;

    /*the maingroup containing the actors*/
    Group m_group;

    /*compiles and creates the shader and also the INPUTLAYOUT!*/
    bool compileAndCreateShader(char* vertexShader, char* pixelShader);
};

带有无重载函数的rror，这里有2个参数：

在init中：

Snake *s = new Snake(this, m_config.get());

Visual Studio不会显示任何语法错误或其他任何不编译的内容。清洁没有帮助。

任何人都有一个线索是什么，我做错了所以我可以让它恢复运行？

根据您对OP的评论，您似乎有一个循环引用问题。

您的Snake标题中未使用

GameBase类。

您需要在 GameBase.cpp 文件中声明#include "Snake.h"声明。

突然一个：语法错误：标识符
