完全替代在很长一段时间内不会发生,你们见过任何一个强大的平台在短期内被完全替代的吗?但是我认为之前所有答案中的理由都站不住脚。技术上说,HTML5已经可以替代Flash的绝大多数特性。而且从HTML5的发展趋势来看,HTML5将逐渐获得对Flash的优势,所以替代趋势肯定是存在的,但不可能是一夜之间发生的。
HTML5对于游戏开发来说存在的问题主要是几个:
1. 各平台各浏览器对HTML5的支持程度不一,包括特性,包括性能表现等都还存在较大差异。
2. 缺乏普遍认同的高质量游戏开发框架和开发工具,特别是HTML5本身不是为游戏开发而设计的,从产业化的角度看,必须要基于框架和工具,否则难成气候。
3. 缺乏足够多的掌握HTML5的游戏开发人员。
人的因素是最关键的。目前掌握HTML5的大多是前端开发人员,而他们缺乏游戏开发经验。而传统游戏开发者大多用Flash和C++,他们缺乏HTML5的经验。不过这个情况在不断变化,一方面,前端转游戏开发的越来越多,他们可以从较简单的休闲游戏和社交游戏入门,逐渐学习复杂游戏的开发,另一方面,也已经有不少Flash开发者转入了HTML5阵营。所以我相信不久之后HTML5游戏开发这个领域应该会有非常大的发展。
问任何一个HTML5游戏开发者两个问题:
1. 如何解决各种浏览器以及同一浏览器不同版本之间的兼容性(游戏体验完全一致)?
2. 如何解决HTML5游戏发布以后明码的问题(任何人通过缓存就能获取整套HTML5资源以及代码,山寨太容易)? 很难讲,HTML5现在炒概念的成分居多,而且推动者都各自“心怀鬼胎”,真要是HTML5发展到可以威胁到某家拳头产品的地位,联盟就会自动瓦解了。
比如APPLE,如果HTML5可以像Flash一样这么普及,APPLE也要考虑是不是对自己app store有影响,支持力度肯定会有折扣。 可以看看Mozilla 的努力
Mozilla and Epic Preview Unreal Engine 4 Running in Firefox
Mozilla 将 Unreal 引擎移植到Firefox
Mozilla 推出了 asm.js,来编译js使其底层化,大大优化其性能
网页端以后特别是交互多的游戏的发展是激动人心的,当然一切还没有那么快 没有快捷的开发工具和几个成熟的产品作为先驱 推广起来很难。
flash在PC平台还是占了非常大的份额! 感觉还有好多年要修炼,几个图表都在各个浏览器显示不一致,更别说那么多的图片动画在移动碰撞了 就算单考虑安全性,也很艰难。 我觉得几年内都不太可能,虽然现在大家都看好,都支持,但还都停留在概念阶段,只靠W3C去推动是不现实的,而像微软,Adobe这样的大佬都有自家的竞争产品(sliverlight,flash),已经非常成熟,没有道理去扛Html5的大旗,没有市场的推力,又面临很多兼容性等的问题,前景的确不明朗. 复杂的还是要用flash的,比如网页游戏 我们学校有个团队用html5的canvas写了一个游戏,感觉很不错。所以,我觉得以后还是很有可能取代flash的。

HTML5 is the latest version of the Hypertext Markup Language, standardized by W3C. HTML5 introduces new semantic tags, multimedia support and form enhancements, improving web structure, user experience and SEO effects. HTML5 introduces new semantic tags, such as, ,, etc., to make the web page structure clearer and the SEO effect better. HTML5 supports multimedia elements and no third-party plug-ins are required, improving user experience and loading speed. HTML5 enhances form functions and introduces new input types such as, etc., which improves user experience and form verification efficiency.

How to write clean and efficient HTML5 code? The answer is to avoid common mistakes by semanticizing tags, structured code, performance optimization and avoiding common mistakes. 1. Use semantic tags such as, etc. to improve code readability and SEO effect. 2. Keep the code structured and readable, using appropriate indentation and comments. 3. Optimize performance by reducing unnecessary tags, using CDN and compressing code. 4. Avoid common mistakes, such as the tag not closed, and ensure the validity of the code.

H5 improves web user experience with multimedia support, offline storage and performance optimization. 1) Multimedia support: H5 and elements simplify development and improve user experience. 2) Offline storage: WebStorage and IndexedDB allow offline use to improve the experience. 3) Performance optimization: WebWorkers and elements optimize performance to reduce bandwidth consumption.

HTML5 code consists of tags, elements and attributes: 1. The tag defines the content type and is surrounded by angle brackets, such as. 2. Elements are composed of start tags, contents and end tags, such as contents. 3. Attributes define key-value pairs in the start tag, enhance functions, such as. These are the basic units for building web structure.

HTML5 is a key technology for building modern web pages, providing many new elements and features. 1. HTML5 introduces semantic elements such as, , etc., which enhances web page structure and SEO. 2. Support multimedia elements and embed media without plug-ins. 3. Forms enhance new input types and verification properties, simplifying the verification process. 4. Offer offline and local storage functions to improve web page performance and user experience.

Best practices for H5 code include: 1. Use correct DOCTYPE declarations and character encoding; 2. Use semantic tags; 3. Reduce HTTP requests; 4. Use asynchronous loading; 5. Optimize images. These practices can improve the efficiency, maintainability and user experience of web pages.

Web standards and technologies have evolved from HTML4, CSS2 and simple JavaScript to date and have undergone significant developments. 1) HTML5 introduces APIs such as Canvas and WebStorage, which enhances the complexity and interactivity of web applications. 2) CSS3 adds animation and transition functions to make the page more effective. 3) JavaScript improves development efficiency and code readability through modern syntax of Node.js and ES6, such as arrow functions and classes. These changes have promoted the development of performance optimization and best practices of web applications.

H5 is not just the abbreviation of HTML5, it represents a wider modern web development technology ecosystem: 1. H5 includes HTML5, CSS3, JavaScript and related APIs and technologies; 2. It provides a richer, interactive and smooth user experience, and can run seamlessly on multiple devices; 3. Using the H5 technology stack, you can create responsive web pages and complex interactive functions.
