Welcome to the Game Development Using Processing.js Workshop!

Intro (me)


Goals & Schedule

  • Develop a simple 2D or 3D game using in Processing
  • 9-11 Examples and exercises
  • 11-12 Work, experiment, collaborate


Processing (aka P5)

  • Processing.org
  • Open source data visualization language
  • Developed in Java
  • "Sketches" written using Java syntax
  • Requires a JVM plug-in
  • Uses the <object> tag
  • Reference
  • Bug tracking


Setting up Processing

  • Download it here
  • Save the .DMG file to the Desktop
  • Double-click to extract file
  • Drag the Processing icon to the desktop
  • Double-click the icon to start


Processing.js (aka PJS)


Setting up Minefield

  • Why use it?
  • Much faster than Firefox
  • Has WebGL
  • Download a working version of Minefield here
  • Instructions to enabled WebGL here

Sokoban

Gotchas

  • Integer/Integer division println(5/2) v.s. println(5/2.0)
  • NPOT (Non Power of Two) textures will not load in 3D
  • color does not use new
