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


Setting up Processing.js

Sample Games

Here are some Processing.js games and prototypes to give you an idea what is possible
3D Pong by bmidgley
Tower Defense by Will Larson and Peter Burns
Core by Andor Salga
Light Cycles by Al MacDonald
Game of Life by Al MacDonald
JS Ninja by Al MacDonald
Zelda by Scott Downe

Challenges

Create an empty sketch and try to code a simple game:
Pong!
Concentration
Flying side-scroller
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
