我正在使用SFML创建使用C ++进行的太空入侵者克隆。我是C ++的新手，在从事此项目时正在学习它。

尝试使用构造函数和数组为每个创建的敌人设置设置来创建新敌人时，出现以下错误：

1>enemy.cpp
1>C:\Users\dzamm\source\repos\SFML\enemy.cpp(35,1): error C2280: 'Enemy &Enemy::operator =(const Enemy &)': attempting to reference a deleted function
1>C:\Users\dzamm\source\repos\SFML\enemy.h(55): message : compiler has generated 'Enemy::operator =' here
1>C:\Users\dzamm\source\repos\SFML\enemy.h(55,1): message : 'Enemy &Enemy::operator =(const Enemy &)': function was implicitly deleted because a data member invokes a deleted or inaccessible function 'sf::RenderWindow &sf::RenderWindow::operator =(const sf::RenderWindow &)'

敌对构造函数：

Enemy alienArray[NUMber_OF_ALIENS];

//constructor sets ID number,loads sprite
Enemy::Enemy(const int id,float sp)
{
    //set alive
    mIsAlive = true;

    //set speed
    enemySpeed = sp;

    // Load an enemy texture
    if (!mEnemyTexture.loadFromFile("Media/Textures/PixelSpaceships/red_01.png")) {
        // Handle loading error
        std::cout << "Oh No! File not loaded." << std::endl;
    }

    //scale sprite and set texture so we know size
    enemySprite.setTexture(mEnemyTexture);
}

敌方加载器方法

void Enemy::loader(int noOfAliens) { // might add xPosition;yPosition

    for (int i = 0; i < noOfAliens; i++)
    {
        Enemy alien(i,10.f); // speed issue
        alien.setLocation(i * 100.f + 50.f,alien.getSprite().getGlobalBounds().height / 2);
line 35     alienArray[i] = alien;
        //alienArray.push_back(alien);
    }
}

    void                    enemyMovement(std::vector<Enemy>& enemyList);

    sf::Sprite              enemySprite;


    //std::vector<Enemy>        alienArray;
    //std::vector<sf::Sprite> mEnemies;
    sf::RectangleShape      mEnemyBounds;

    sf::RenderWindow        mWindow;


    bool                    mIsShooting;
    bool                    mIsAlive;
    float                   enemySpeed;
};

我在论坛上阅读了与该对象的副本而不是原始对象有关的问题，但是我不确定如何处理该引用以引用我正在修改的原始对象。

要重现为Enemy.cpp类创建构造函数，请使用Enemy :: loader中所示的for循环方法在Enemy：c中创建一个实体Enemy外星人，并将创建的实体存储在Enemy AlienArray中，如索引所示。
