C++已知游戏中常见人物状态State抽象类，包括站立（Idle），行走（Run），攻击(Attack)，死亡(Dead)等动作。在游戏中有角色hero类，拥有人物状态同时还拥有血量，攻击力，防御力等属性,有怪物类Monster,怪物有血量，攻击力，防御力，怪物类型等属性。 已知角色可以变身为怪物，现在main函数中，模拟某个角色在正常情况下以及在变身状态下的各种状态操作(输入1为正常hero，输入2则变身为monster)。 并补充下列代码 #include <iostream> using namespace std; #include<string> #include"time.h" #include"math.h" int main() { State *s; s->idle(); s->attack(); s->run(); s->dead(); return 1; }

首先，需要定义State抽象类，包括idle、attack、run、dead四个纯虚函数：

class State {
public:
    virtual void idle() = 0;
    virtual void attack() = 0;
    virtual void run() = 0;
    virtual void dead() = 0;
};

然后，定义Hero和Monster两个类，分别继承State类，并且拥有各自的属性：

class Hero : public State {
public:
    int hp;
    int attack;
    int defence;
    void idle() {
        cout << "Hero is idling." << endl;
    }
    void attack() {
        cout << "Hero is attacking." << endl;
    }
    void run() {
        cout << "Hero is running." << endl;
    }
    void dead() {
        cout << "Hero is dead." << endl;
    }
};

class Monster : public State {
public:
    int hp;
    int attack;
    int defence;
    string type;
    void idle() {
        cout << "Monster is idling." << endl;
    }
    void attack() {
        cout << "Monster is attacking." << endl;
    }
    void run() {
        cout << "Monster is running." << endl;
    }
    void dead() {
        cout << "Monster is dead." << endl;
    }
};

最后，在main函数中，根据用户输入的情况，创建相应的对象，并调用对象的函数：

int main() {
    srand(time(NULL));
    int choice;
    cout << "Enter 1 for hero, 2 for monster: ";
    cin >> choice;
    State *s;
    if (choice == 1) {
        Hero hero;
        hero.hp = rand() % 100 + 1;
        hero.attack = rand() % 10 + 1;
        hero.defence = rand() % 10 + 1;
        s = &hero;
    }
    else if (choice == 2) {
        Monster monster;
        monster.hp = rand() % 100 + 1;
        monster.attack = rand() % 10 + 1;
        monster.defence = rand() % 10 + 1;
        monster.type = "Spider";
        s = &monster;
    }
    s->idle();
    s->attack();
    s->run();
    s->dead();
    return 0;
}

需要注意的是，如果要让角色能够变身为怪物，需要在Hero类中添加一个函数，将Hero对象的状态改变为Monster对象：

void transform() {
    Monster monster;
    monster.hp = rand() % 100 + 1;
    monster.attack = rand() % 10 + 1;
    monster.defence = rand() % 10 + 1;
    monster.type = "Spider";
    *this = monster;
}

然后，可以在main函数中添加如下代码，实现角色变身：

if (choice == 1) {
    Hero hero;
    hero.hp = rand() % 100 + 1;
    hero.attack = rand() % 10 + 1;
    hero.defence = rand() % 10 + 1;
    s = &hero;
    cout << "Enter 1 for normal, 2 for transform: ";
    cin >> choice;
    if (choice == 2) {
        hero.transform();
    }
}
