复制构造函数丢失一些属性

Question

我有一个类Block

的复制构造函数

Block::Block(const Block& p_block):Drawable(p_block) {
}

继承自班级Drawable

Drawable::Drawable(const Drawable& p_drawable) {
    sprite = p_drawable.sprite;
    texture = p_drawable.texture;
    x = p_drawable.x;
    y = p_drawable.y;
}

我使用指针来存储对象，但是试图切换到不使用指针，现在精灵和纹理都丢失了。我非常确定我对引用/指针的使用是非常错误的。

绘制方法：

void Room::draw(sf::RenderWindow &p_window) {
    for(auto& block : blocks) {
        block.draw(p_window);
    }
...
}

可以包含任何其他必要的代码。只是想知道我是否在复制构造函数中做错了什么，或者我是否应该使用指针。

我也将此用于碰撞，不确定此处的某些内容是否可能导致问题。

struct sortBlocksByDistance {
    Drawable *drawable;
    sortBlocksByDistance(Drawable* p_drawable) {
        this->drawable = p_drawable;
    }
    bool operator () (Block* a, Block* b) {
        float adx = a->x - drawable->x,
        ady = a->y - drawable->y,
        adist = adx * adx + ady * ady;

        float bdx = b->x - drawable->x,
        bdy = b->y - drawable->y,
        bdist = bdx * bdx + bdy * bdy;

        return adist < bdist;
    }
};

std::vector<Block*> Room::detectCollisions(Drawable *p_drawable) {
    std::vector<Block*> hitBlocks;
    for(auto& block : blocks) {
        if(block.collidesWith(p_drawable)) {
            hitBlocks.push_back(&block);
        }
    }
    std::sort(hitBlocks.begin(), hitBlocks.end(), sortBlocksByDistance(p_drawable));
    return hitBlocks;
};

std::vector<Block*> collisions = detectCollisions(player);
player->solveCollisions(collisions);

void Drawable::solveCollisions(std::vector<Block*> p_blocks) {
    while(p_blocks.size()) {
        Block &block = *p_blocks.front();
        // x/y manipulation

        // pop front
        p_blocks.front() = std::move(p_blocks.back());
        p_blocks.pop_back();
    }
};
