About Me

• Ameteur programmer and game developer
• High school now, College in the future
• Seeking a job as a developer!

Jython

• CPython is the reference implementation for Python.
• Jython is a Python implementation in Java
• Offers superb interoperability with Java libraries, along with the amazing benefits of the JVM
• 2.7 betas are out!

Comparisons of CPython and Jython

#Jython                  |  #CPython
def fibonacci():         |  def fibonacci():
    a, b = 0, 1          |      a, b = 0, 1  
    while True:          |      while True:
        yield a          |          yield a
        a, b = b, a + b  |          a, b = b, a + b

LibGDX

• A cross-platform Java game development framework based on OpenGL (ES) that works on Windows, Linux, Mac OS X, Android, your WebGL enabled browser and iOS.

My Work with LibGDX

• Translated the LibGDX wiki (GoogleCode -> Github)
• Worked on Polyglot LibGDX (as shown in this very talk!)
• Regular on IRC
• Started Game-dev club at my school to teach and create games with LibGDX

LibGDX Classes Of Use

• ApplicationListener is the base java interface for a LibGDX game
• OrthographicCamera for camera magic
• SpriteBatch to draw on the screen
• Standard Math classes Vector2, Rectangle, etc.

Small example!

• Small game from wiki translated to Python
• To the demo! (lets hope this works!)

Limitations of LibGDX with Jython

• GWT
  • This backend is java only, so HTML LibGDX backend is a pipe dream

Future

• Android Support

  • Once jython can attain DynamicProxy support, it might be possible to have Jython on android!

• iOS support

  • the RoboVM backend runs the Android class library, so if it can anddroid, theres a good chance it can iOS!

• packaging

  • There has been some work on compiling/packaging jython into jars, this will make distribution of your awesome Python games very easy!
