C++文本RPG庫存系統

Question

我正在構建文本-RPG庫存系統，但我不確定如何正確創建equipable項目。 例如，我可以裝備在玩家庫存中的物品，但我不能識別什麼樣的物品（劍，盾，手套或其他物品），因爲物品應該裝在適當的地方（頭盔，劍在手等）。 有沒有辦法做到這一點？

#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

有很多可能性來做到這一點。

簡單的方法

首先，你必須保持不串物品的清單，：

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

然後，你必須使用Inventroy[i].name到seacrh和使用inventory[i].purpose找到合適的插槽：

 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; 
      } 
     } 

稍作改進

請注意，對於您的遊戲的下一次改進，您會遇到類似的問題，因爲它是一個字符串矢量，您不會直接訪問該項目的屬性，例如對攻擊的影響或防守裝備。

因此你也應該做一個Equipmentvector<Item>：

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

你也可以考慮把庫存，便於訪問的map<string, Item>按名稱
