C++ Text-RPG 库存系统

Question

我正在构建文本-rpg 库存系统，但我不确定如何正确创建可装备的物品。 例如，我可以装备玩家库存中的物品，但我无法确定是哪种物品（剑、盾、手套或其他东西..），因为物品应该装备在适当的位置（头盔在头上，剑在手中等等）。 有什么办法吗？

#include <iostream>
#include <vector>
#include <Windows.h>
#include <string>

using namespace std;

void Red()
{
    SetConsoleTextAttribute
    (GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_RED | FOREGROUND_INTENSITY);
} //Intensive red console text color.

void Green()
{
    SetConsoleTextAttribute
        (GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_GREEN | FOREGROUND_INTENSITY);
} //Intensive green console text color.

void Normal()
{
    SetConsoleTextAttribute
        (GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_GREEN | FOREGROUND_RED | FOREGROUND_BLUE);
} //Default console text color.

struct Item{
    string name; //Item name.
    int price; //Item price.
    int purpose; // 0 - Head, 1 - Neck, 2 - Torso, 3 - Hands, 4 - Legs, 5 - Feets.
    int attribute; //Attack, Defense...
};

int main()
{
    //Isn't the smartest way to do so...
    Item Sword{
        "Sword", //This item name is 'Short Sword'.
        87, //Cost 87 gold pieces.
        3, //Use this item with hands. :D.
        10 //+10 attack.
    };

    string input; // input is for player commands.
    vector<string> Equipment = { "<Empty>", "<Empty>", "<Empty>", "<Empty>", "<Empty>","<Empty>" }; //Current equipment.
    vector<string> Inventory = {Sword.name}; //Player Inventory.
    string InventorySlots[] = { "Head", "Neck", "Torso", "Hands", "Legs", "Feets" }; //Player parts where items can be equiped.

    while (true){
        cin >> input;
        if (input == "equipment"){
            for (int i = 0; i < 6; i++){
                Normal();
                cout << InventorySlots[i];
                if (Equipment[i] == "<Empty>")
                    Red();
                cout << " " << Equipment[i] << endl << endl;
            }
            Normal();
        }

        if (input == "equip"){
            cout << "What do you want to equip? ";
            cin >> input;
            for (int i = 0; i < Inventory.size(); i++){
                //Search for item player want to equip and equip it in the right place.
                if (input == Inventory[i]){
                    //Inventory[i] = input;
                    //But how to identify what kind of item it is?
                    cout << "Successfully equiped!" << endl;
                }
            }
        }

        if(input == "inventory"){
            for (int i = 0; i < Inventory.size(); i++){
                cout << "______________________________________________________________" << endl;
                cout << "|  " << Inventory[i] << endl;
                cout << "|  Carried items " << Inventory.size() << " / " << 20 << endl;
                cout << "|_____________________________________________________________" << endl;
            }
        }

    }
    system("PAUSE"); // or 'cin.get()'
    return 0;   
}

Answer 1

有很多可能性可以做到这一点。

简单的方法

首先，您必须保留物品清单，而不是字符串：

vector<Item> Inventory = {Sword, Helmet}; //Player Inventory.

然后您必须使用Inventroy[i].name 搜索并使用inventory[i].purpose 找到正确的插槽：

        for(int i = 0; i < Inventory.size(); i++){
            //Search for item player want to equip and equip it in the right place.
            if(input == Inventory[i].name){
                Equipment[Inventory[i].purpose] = Inventory[i].name; 
                cout << "Successfully equiped!" << endl;
            }
        }

略有改进

请注意，对于您的游戏的下一次改进，您的设备会遇到类似的问题：由于它是一个字符串向量，您将无法直接访问项目的属性，例如效果攻击或防御装备。

因此，您还应该将Equipment 设为vector<Item>：

Item Empty{"<Empty>", 0, 0, 0};
vector<Item> Equipment{6, Empty};  //Current equipment: 6 x Empty.
...

您还可以考虑将 Inventory 设为 map<string, Item>，以便通过名称轻松访问
