Python - 基於文字的冒險遊戲（使用 pygame）

開發一個簡單的文字冒險遊戲是教授 Python 基礎知識的好方法，尤其是在使用 pygame 庫設計時。

本教程將包含有關如何構建遊戲的詳細分步說明，其中包括在一個房間中搜索鑰匙並開啟圖書館門的步驟。在本教程中，您將學習有關 pygame 的安裝、程式碼每個步驟的解釋以及如何運行遊戲及其輸出的方法。

安裝

首先，檢查您的計算機上是否安裝了 Python。這就是 **pygame** 發揮作用的地方，它是 Python 的一個開源遊戲和多媒體開發庫。

要安裝 **pygame**，您需要在計算機上開啟 cmd 或終端，然後輸入以下指令：

pip install pygame

基於文字的冒險遊戲的程式碼

以下是我們基於文字的冒險遊戲的完整程式碼。遊戲包含幾個房間：大廳、花園、餐廳和圖書館。玩家可以訪問兩個房間以嘗試找到隱藏的鑰匙。如果他們找到鑰匙，他們就可以進入圖書館房間。如果玩家在允許的嘗試次數內未能找到鑰匙，遊戲將結束。

使用的圖片

以下是我們在上述程式碼中用於設計基於文字的冒險遊戲的圖片：

這些是我們使用的圖片。您也可以從 Google 下載隨機圖片並使用它們。

運行遊戲的步驟

**設定** - 首先確保您已安裝 Python 以及 Pygame。
**準備圖片** - 將所需的房間圖片（hall.png、garden.png、dining_room.png 和 library.png）放在與 Python 指令碼相同的目錄中。
**執行指令碼** - 透過在您的終端或命令提示符中執行 python your_script_name.py 來執行指令碼。
