c++ - 动态创建对象并将它们添加到链表中

Question

这是一款 C++ 控制台游戏，其中包含发射炮弹的坦克。问题出在坦克外壳部分。 我想创建一个 PlayerTankShell 类的对象，并在每次按下空格键时将其添加到链表中。我该怎么做？

这是我的代码:

#include <iostream>
#include <conio.h>
#include <list>

using namespace std;

#define ATTACK  32

class PlayerTankShell
{
    int x;
    int y;
    int speed;
    bool isExist;

public:
    PlayerTankShell(bool exists)
    {
        isExist = exists;
    }
    bool getExistense()
    {
        return isExist;
    }
};

int main()
{
    char input;
    input = getch();

    if (input == ATTACK)
    {
        // Here create an object and add it to the linked list
    }

    // My test so far:
    PlayerTankShell *s1 = new PlayerTankShell(1);
    PlayerTankShell *s2 = new PlayerTankShell(1);
    PlayerTankShell *s3 = new PlayerTankShell(1);

    list<PlayerTankShell> listShells;

    listShells.push_back(*s1);
    listShells.push_back(*s2);
    listShells.push_back(*s3);

    list<PlayerTankShell>::iterator i;

    for (i = listShells.begin(); i != listShells.end(); i++)
    {
        cout << "exists=" << i->getExistense() << endl;
    }

    return 0;
}

你想要这样的东西:

std::list<PlayerTankShell> shells;

然后你可以添加:

shells.push_back(PlayerTankShell(true))
