C++向量迭代错误

Question

monster* monster1 = new monster("Frankenstein", "The Ugly One", BackYard);
Player* player1 = new Player("Corey", "The Chosen one", Atrium);
Player* player2 = new Player("Darth Vader", "The Evil One", Atrium);
vector<Agent*> agents;
agents.push_back(monster1);
agents.push_back(player1);
agents.push_back(player2);

while (true)
{
    vector<Agent*>::iterator it;

    for (it = agents.begin(); it < agents.end(); it++) {
        it->act();                                            // Error here
        if (it->act() == false)                               // Error here
            return 0;
    }

    ...
}

我收到一个错误说:

成员引用基类型'Agent*'不是结构或联合.

我真的不明白为什么这不能导航向量.

Answer 1

it指向Agent*不是Agent. it->将尝试在指针上调用函数而不是对象.您需要做的是取消引用迭代器,然后调用成员函数.

(*it)->act();
