HTML5 Games Status and issues

  1. 1. HTML5 Games Status and issues Hong,Sechul/CTO
  2. 2. 2Why HTML5 Game? Cross device running (with one source code) Dynamic update (without explicit installation) However…
  3. 3. 3Problems JavaScript - Dynamic binding interpreter language Low performance Hard to manage memory Browser quirks Browser/device performance discrepancy Sound and device API Packaging  HTML5 is originally not for games!
  4. 4. 4HTML5 for game development Controlling • JavaScript Rendering • HTML5 DOM/CSS3 • HTML5 Canvas • HTML5 WebGL Sound • HTML5 Audio API • WebAudio API(Chrome)
  5. 5. 5Renderer for gamesIn view of commercializing HTML5 games; Devices Game types HTML5 • PC Browsers (Even non-HTML5 Plain, Tile-map, DOM/CSS3 Browsers) Arcade • Android/iOS • TIZEN • Some TV/Set-top-box HTML5 • HTML5 PC Browsers Plain, Tile-map, Canvas • iOS Arcade, Physics • TIZEN(?) • Some TV/Set-top-box(?) HTML5 • Chrome Brower on Windows 3D(OpenGL like) WebGL
  6. 6. 6Market perspectives by rendererIn view of commercializing HTML5 games; HTML5 DOM+Canvas • Cross device running • Game type : Social, Casual HTML5 Canvas • PC • Game type : Social, Casual, Physics WebGL • Existing iOS and Android games to Chrome web store • Game type : 3D
  7. 7. 7Technical Issues - JavaScript Interpreting, dynamic binding Implicit garbage collection Vulnerable environment for developers  Need to impose strict coding pattern  Need framework, engine  Recycling of resource
  8. 8. 8Technical Issues – HTML5 Specs (1/2) HTML5 implementations are stable over browsers.But, problems are mostly on Device API. Viewport control – Screen lock, Orientation lock, Full- screen  For some platform, need to package as native application  Android has more problems when running as web site Audio API  Unstable and lots of quirks in implementation  Only 1 channel for many browsers  Preparing new WebAudio API
  9. 9. 9Technical Issues – HTML5 Specs (2/2) Storage API  Using File-System API along with Cookie  For permanent and critical data, need server backup. Packaging & Installation  PC : Hard to package large game. Hard to add Ad with installable package. Mostly hosting with CDN.  Mobile : W3C widget like package. Native application(Hybrid). Hosting is relatively good for iOS(without sound) MouseLock API, JoyStick API  Developing by Google
  10. 10. 10Technical Issues – Screen sizes Matter of game geometric type, level design, graphical assets and layouts. Not specific to HTML5 games. HTML5 itself is good for resizing - Relative coordination system, CSS, Zooming  Relative coordination from the beginning of development  CSS tricks  Zooming : Drops performance a lot. (But, TIZEN looks good!)  BLUEGA : Using Game level editor
  11. 11. 11Technical Issues – Game UI Need to develop game’s other screens, dialogs and menu. Need some UI framework library for renderer HTML5 itself is very good for developing UI. UI frameworks such jQuery, Sencha, …  BLUEGA : Developing all Game UI in HTML5 DOM even running with HTML5 Canvas. (Using own jBLUX)
