專案簡介

本專案報名參加了“兗州中材杯”武漢理工大學第十一屆環保創意作品大賽藝術理念組比賽。組員共三名，本人負責程式碼實現部分，其餘兩人分別負責專案策劃與場景人物繪製。

專案背景

小組中負責策劃的同學經過一定的調研之後發現，我校在校學生普遍缺乏垃圾分類方面的知識。經過討論後，我們把遊戲方向定位於“垃圾分類”，遊戲型別定位於畫素風遊戲，由於本人水平和時間有限，只能將玩法設計得儘量簡單。感謝另外兩位組員，他們的努力掩蓋了我水平上的不足。

玩法介紹

家控制一名角色在操場背景上移動，垃圾桶在操場邊上。撿起垃圾丟進相應的垃圾桶內，若全部正確投放則遊戲成功，否則遊戲失敗。遊戲期間，若有不清楚該作何分類的垃圾，則可以點選圖書館的按鈕，進入圖書館查詢。圖書館提供垃圾圖鑑和分類標準兩種資訊。垃圾圖鑑幫助玩家分辨自己撿到的垃圾，而分類標準指每種垃圾的定義及舉例。

專案成果

本專案在“兗州中材杯”武漢理工大學第十一屆環保創意作品大賽藝術理念組比賽中最終獲得了第五名、二等獎的成績，距第四名僅差0.5分。

專案實現

寫專案時本人僅自學了一個月的Python，且本人是大一新生，對電腦科學的基礎知識瞭解甚少，若程式碼風格幼稚、愚蠢，還望讀者見諒。

模組劃分

遊戲按場景分為以下幾個模組：開始遊戲介面、遊戲說明介面、人物選擇介面、操場介面（主要遊戲場地）、圖書館外介面、圖書館內介面、遊戲結束介面。

開始遊戲介面：背景（畫素化的學校建築），遊戲標題，三個按鈕（開始、遊戲說明、退出）。

遊戲說明介面：背景（與開始介面相同），遊戲說明文字，返回按鈕。

人物選擇介面：背景，提示（選擇人物），兩個可選人物。

操場介面：背景，人物，垃圾桶，隨機產生的垃圾，圖書館按鈕。

圖書館外介面：背景（我校圖書館的畫素風繪製）、操場按鈕（會到操場）、進入按鈕（進入圖書館內部）。

圖書館內介面：背景（我校圖書館內部），各類垃圾圖示按鈕（廚餘垃圾、可回收垃圾、有害垃圾、其他垃圾），垃圾圖鑑按鈕，返回按鈕。子介面：各類垃圾資訊介面，垃圾圖鑑介面，返回按鈕。

遊戲結束介面：勝利介面，失敗介面。
