我试图从头开始编写一个简单的文本冒险游戏的代码作为编程练习，并得到了令人惊讶的结果。这是完整的代码：
//Twisty Passages All Alike.
//An adventure game designed as a practice exercise.
#include <iostream>
#include <string>
using namespace std;
int main()
{
cout << "\t\tTwisty Passages, All Alike!\n";
cout << "\tA text adventure by Jellypox Studios.\n";
//INVENTORY INDEX NUMBERS:
//0. note
//1. hammer
//2.
//ROOM NUMBERS:
//0. living room
//1. storeroom
//Setting up the current room.
int ALL_ITEMS = 10;
string inventory[ALL_ITEMS];
int currentRoom = 0;
string input = "DEFAULT";
//Room 0: living room.
bool haveNote = false;
bool haveHammer = false;
//Room descriptions
if (currentRoom == 0)
{
cout << "You are in the living room.\nThere are doors to the south and west and a staircase to the north.\nYou can see: a table, a cat, a fireplace.\n\n";
}
else if (currentRoom == 1)
{
cout << "You are in the storeroom.\nThe room is a jumbled mass of cupboards, hanging sausages, left-out scraps of food and cockroaches.\nThe only thing of interest here is a large chest in the corner.";
}
//THE LIVING ROOM
while (currentRoom == 0)
{
cin >> input;
//THE TABLE
if (input == "look table" || "look at table")
{
cout << "You see: some bones and scraps";
if (haveHammer = false)
{
cout << ", a hammer";
}
if (haveNote == false)
{
cout << ", a note";
}
cout << ".\n\n";
}
else if (input == "look scraps" || "look at scraps" || "look bones" || "look at bones")
{
cout << "What a mess!\n\n";
}
else if (input == "look note" || "look at note" || "read note")
{
if (haveNote == false)
{
cout << "Pick it up first!\n\n";
}
else
{
cout << "It reads: \"Gone hunting. Will be back soon.\"";
}
}
else if (input == "get note" || "take note" || "pick up note")
{
if (haveNote == false)
{
cout << "Got the note.";
inventory[0] = "note";
haveNote = true;
}
else
{
cout << "You already have the note!\n\n";
}
}
else if (input == "look hammer" || "look at hammer")
{
cout << "It's just an ordinary hammer.\n\n";
}
else if (input == "get hammer" || "take hammer" || "pick up hammer")
{
if (haveHammer == false)
{
cout << "Got the hammer.\n\n";
inventory[1] = "hammer";
haveHammer = true;
}
else
{
cout << "You already have the hammer!\n\n";
}
}
//ELSWHERE IN THE ROOM
else if (input == "look cat" || "look at cat")
{
cout << "It stares up at you irritably.\n\n";
}
else if (input == "look fireplace" || "look at fireplace")
{
cout << "A flickering fire warms the house.\n\n";
}
else if (input == "south" || "go south")
{
//CODE TO MAKE THE DOOR UNLOCKABLE GOES HERE!
cout << "The door is locked.\n\n";
}
else if (input == "west" || "go west")
{
currentRoom = 1;
}
else if (input == "north" || "go north" || "upstairs" || "go upstairs")
{
currentRoom = 2;
}
else
{
cout << "Say what?";
}
}
return 0;
}
我尝试对输入/输出系统使用 while 循环，这样如果您键入“查看表格”，它会为您提供表格的描述等，但它会执行以下操作：
look at table
You see: some bones and scraps, a note.
You see: some bones and scraps, a note.
You see: some bones and scraps, a note.
get note
You see: some bones and scraps, a note.
You see: some bones and scraps, a note.
get hammer
You see: some bones and scraps, a note.
You see: some bones and scraps, a note.
go west
You see: some bones and scraps, a note.
You see: some bones and scraps, a note.
我做错了什么？
