Essential TypeScript

★從零開始，拆掉遊戲製作的門檻★ ☆本書作者獲2022 iThome鐵人賽—優選☆ 網頁遊戲可說是最方便廣傳的發布平台，二十一世紀初期的Flash大一統年代已經證明了，不管規模多麼小、點子多麼荒誕不經的網頁遊戲，都有機會在網路上大放異彩。 自Flash走下神壇，HTML5取而代之，隨著技術的發展，網頁遊戲的開發工具變得越加成熟。 在網頁繪圖引擎的大海中，Pixi.js無疑是繼承了Flash精神的佼佼者，不但提供了高效、輕量級的圖像渲染、動畫特效，而且對於我們程式設計師來說，更有著功能清晰易懂、入門快速上手的好處。 此外，Pixi.js還是以TypeScript為語言撰寫的函式庫。TypeScript是JavaScript的一個超集，提供了靜態類型檢查和推斷等特性，不僅提高了程式碼的可讀性和可維護性，還大大地減少錯誤的發生。本書將並進介紹TypeScript的語法與Pixi.js的功能，通過實例演示如何使用這兩大工具，從零到有地開發網頁遊戲。 透過本書，您將學會如何以最先進的網頁技術製作遊戲，從開發環境的組建、基礎程式編輯概念、TypeScript語法、Pixi.js繪圖功能，到響應式遊戲尺寸、鍵盤滑鼠的操作、物理引擎的引入，再到網頁遊戲的發布和匯出手機遊戲的方法，本書提供了全面的指引與詳解，幫助您輕鬆掌握網頁遊戲製作的知識與技巧。 在WebView全面嵌入作業系統的今天，網頁技術成為支援多平台軟體的熱門選擇之一，對於遊戲製作的新手，更是一片充滿機運的天地。 讓我們一起打開這扇大門，創造屬於自己的遊戲世界吧！ 本書內容分成四大部分： 1.開發環境的組建（第一、二章） 2.函式庫的建立（第三、四、五章） 3.實作遊戲（第六、七、八、九章） 4.發布遊戲於網頁與手機（第十章） 本書的適用對象 因為撰寫時所想像的閱讀對象是完全的入門者，也就是對遊戲製作抱有夢想卻不得其門而入的新手，所以內容除了加入許多程式設計上的解說與邏輯推衍的過程，也會避免使用過於行內的字眼。如果有不得不使用的專業術語，會加開小節對其詳加介紹。 在程式碼的演示上，則儘量將長篇大論切成許多小段來逐步解釋，希望能大幅降低閱讀壓力。 對於已經有程式底子的讀者，書中也有許多軟體設計模式的概念，還有各種遊戲中常用的演算法，供讀者學習思考與印證。

The Law of the People’s Republic of China on Safeguarding National Security in the Hong Kong SAR (the “NSL”) promises to be the most important legal development in Hong Kong since the advent of the Basic Law. Many wondered in the aftermath of the NSL how the foundations of Hong Kong’s system might be changed and in what way the freedoms valued by Hong Kong may be affected. Supporters view the law as essential for the preservation of public order and the national security of China and for supporting the fundamental well-being of “One Country, Two Systems”, an arrangement that has been in place since the return of Hong Kong to China. Critics fear an adverse impact on the spirit of “One Country, Two Systems”. From a discussion initiated by the University of Hong Kong’s Faculty of Law, this collection of essays brings together leading experts on Hong Kong and Chinese law to offer an exploratory study of the NSL and its impact on the legal system and the principle of the rule of law in Hon
