c++ - 帮助 C++ 中的对象

Question

我有密码

class ogre
{
    public:
        int health;
        bool isalive;
        string name;
};

int fight()
{
    cout << "You're now fighting an ogre!" << endl;

    ogre ogre;
    player player;
    int ogredamage;
    int playerdamage;

    srand(time(NULL));

    ogre.name = "Fernando Fleshcarver";
    ogre.health = 100;
    ogre.isalive = true;

    player.health = 10000000;
    player.isalive = true;

    while(ogre.isalive = true)
    {
        ogredamage = rand() % 20;
        cout << ogre.name << " deals " << ogredamage << " damage to you!" << endl;
        player.health = player.health - ogredamage;
        cout << "You have " << player.health << " health left." << endl << endl;

        playerdamage = rand() % 20;
        cout << "You deal " << playerdamage << " damage to " << ogre.name << endl;
        ogre.health = ogre.health - playerdamage;
        cout << ogre.name << " has " << ogre.health << " health left." << endl;

        ogre.isalive = false;

    }

    return 0;
}

编译正常，但是，当我尝试将“ogre.isalive”(在代码的最底部)设置为 false 时，什么也没有发生，代码一直在循环。我做错了什么？

Answer 1

ogre.isalive = true 

是一个任务! while 循环将始终运行，因为分配的结果始终为真。您需要 == 来测试相等性。更好的是，只需使用

while(ogre.isalive)
