c++ - 尝试实例化新对象时出错

Question

我有一个 AdventureGame 类，它有一个构造函数。当我尝试创建一个新的 AdventureGame 对象时，我收到错误消息“没有匹配函数来调用‘AdventureGame::AdventureGame()’

这是我的一些类、构造函数和 main。

#include <iostream>
#include <string>
#include <fstream>
using namespace std;

class AdventureGame 
{
private:
public:
    int playerPos;
    int ogrePos;
    int treasurePos;
    string location;

    AdventureGame(int ogre, int treasure) 
    {
        playerPos = -1;
        ogrePos = ogre;
        treasurePos = treasure;
        location = "";
    }; 

.
.
.  // other functions that I'm sure are irrelevant
.
.

    int main() 
    {
        AdventureGame game;
        int numMoves = 0;
        std::string move;

        while (!game.isGameOver(game.playerPos)) 
        {
            game.printDescription(game.playerPos);
            cout << "Which direction would you like to move? (forward, left, or right)" << endl;
            cin >> move;
            game.move(move);
            numMoves++;
        }
    }

如何创建新游戏？

Answer 1

您的构造函数需要两个参数，您需要将它们传递给它们。

例如:

AdventureGame 游戏(3,5);
