c++实现贪吃蛇

c++面向对象实现控制台贪吃蛇

学习了c++面向对象方面的知识，闲着无聊写了贪吃蛇，主要由下面几个类组成：

• MAP类实现地图的渲染
• 蛇类实现蛇的初始化，渲染，行走，吃食物等行为
• *食物类实现食物的初始化及生成
• point类实现坐标类
• 工具函数包括光标移动，控制台设置,随机数生成等

代码：

• MAP类

class Map
{
public:
    void initialization();
private:

};
inline void Map::initialization()
{
    gotoxy(15, 0);
    cout << "贪吃蛇" << endl;
    for (int i = 0; i < 50; i++)
    {
        gotoxy(i, 1);
        cout << "=";
    }
    for (int j = 1; j < 21; j++)
    {
        gotoxy(0, j);
        cout << "#";
    }
    for (int n = 1; n < 21; n++)
    {
        gotoxy(50, n);
        cout << "#";
    }
    for (int v = 1; v < 51; v++)
    {
        gotoxy(v, 20);
        cout << "=";
    }
}

• Snack类

class Snack
{
public:
    void initialization();
    void move();
    void turn(int key);
    void draw();
    void collision(Food& food);
    void drawscore();
    friend class Food;
private:
    vector SnackNode;
    int score;
};
inline void Snack::draw() {
    for (int i = 0; i < SnackNode.size(); i++)
    {
        gotoxy(SnackNode[i].get_x(), SnackNode[i].get_y());
        cout << "■";
    }

    Sleep(0.5 * 1000);
    system("cls");
}
void Snack::collision(Food& food)
{
    cout << SnackNode[0].get_x();
    if (SnackNode[0].get_x()>=51 || SnackNode[0].get_y()>=51)
    {
        //exit(0);
    }
    if (SnackNode[0].get_x() == food.point.get_x()&&SnackNode[0].get_y()==food.point.get_y())
    {
        SnackNode.push_back(food.point);
        if (food.get_flag()==1)
        {
            food.set_flag(0);
            score++;
        }

    }

}
inline void Snack::drawscore() {
    gotoxy(80, 5);
    cout << "大人，你的分数是：" << score;
}
inline void Snack::initialization()
{
    Point tail(1, 8,RIGHT);
    Point body(3, 8, RIGHT);
    Point head(5, 8,RIGHT);
    SnackNode.push_back(head);
    SnackNode.push_back(body);
    SnackNode.push_back(tail);

}
inline void Snack::move() {
        for (int i = SnackNode.size()-1; i >0; i--)
        {

            SnackNode[i].set_x(SnackNode[i - 1].get_x());
            SnackNode[i].set_y(SnackNode[i - 1].get_y());

        }

        switch (SnackNode[0].get_direct())
        {
        case UP:
            SnackNode[0].setup(); 
            break;
        case RIGHT:
            SnackNode[0].setright(); 
            break;
        case LEFT:
            SnackNode[0].setleft(); 
            break;
        case DOWN:
            SnackNode[0].setdown(); 
            break;
        default:
            break;
        }
}
inline void Snack::turn(int key) {
    switch (key)
        {
        case 72: {
            if (SnackNode[0].get_direct() != DOWN)
            {
                SnackNode[0].set_direct(UP);
            }
            break; }
        case 77: {if (SnackNode[0].get_direct() != LEFT)
        {
            SnackNode[0].set_direct(RIGHT);
        }
                 break; }
        case 75: {if (SnackNode[0].get_direct() != RIGHT)
        {
            SnackNode[0].set_direct(LEFT);
        }
                 break; }
        case 80: {if (SnackNode[0].get_direct() != UP)
        {
            SnackNode[0].set_direct(DOWN);
        }
                 break; }
        default: break;
        }

}

• Food类

 class Food
{
public:
    Food(int flag1 = 0) :flag(flag1) {}
    void food_coor();
    void food_draw();
    int get_flag() const { return flag; }
    void set_flag(int fg) { flag = fg; }
    friend class Snack;
private:
    Point point;
    int flag;
};

inline void Food::food_coor()
{
    point.set_x(Random(4,47));
    point.set_y(Random(2,18));
    flag = 1;

}
inline void Food::food_draw() {
    gotoxy(point.get_x(), point.get_y());
    cout << "@";
}

• 工具函数

 void gotoxy(int x, int y)
{
    COORD loc = { x,y };
    HANDLE hOutput = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleCursorPosition(hOutput, loc);
}
void setwindows() {
    HANDLE handle = GetStdHandle(STD_OUTPUT_HANDLE);
    CONSOLE_CURSOR_INFO CursorInfo;
    GetConsoleCursorInfo(handle, &CursorInfo);//获取控制台光标信息  
    CursorInfo.bVisible = false; //隐藏控制台光标  
    SetConsoleCursorInfo(handle, &CursorInfo);
}

• main函数

int main()
{
    setwindows();
    Map map;
    Snack snack;
    Food food(0);
    snack.initialization();
    while (true)
    {

        while (!_kbhit())
        {
            if (food.get_flag() == 0)
            {
                food.food_coor();
            }
            map.initialization();
            snack.draw();
            snack.move();

            food.food_draw();
            snack.collision(food);
            snack.drawscore();
        }   
        snack.turn(_getch());
    }
    getchar();
    return 0;
}

c++真好玩 QAQ！
