To run:

1. Download and add project to eclipse.
2. In your Scratch project, click "File>Download as .sb2". (Note: does not work on Safari.)  3. Import your .sb2 file into the eclipse project, at the outermost level (the same directory that has src/ in it.)
3. Open main.java.jatch.Main. Run it. You should get an error.
4. Go to Run>Run Configurations. Click arguments. Add the name of your .sb2 in program arguments.
5. Run Main again. It should spit out some text into the console.
6. Right-click the src/ folder and click "refresh".
7. Your newly compiled project is in compiled/. Run the Game class.

Note: The repo comes with several pre-downloaded .sb2s just for you!

jatch's Issues

Interfaces => classes

There's no point in Sprite or List or Variable being interfaces -- what's going to implement them? I propose making them all classes and having Sprite handle the core of the graphics, along with a controller class of some kind.

Boolean operations do not work

The tokens are parsed as and and or when they should be parsed as & and |.

Sprite Initialization

Ideas:

have a Sprite.initialize() that takes a bunch of stuff, passed in in the Controller constructor.
Note: the current stuff in the initialize() should be made static.

whenKeyPressed

whenKeyPressed is currently handled as default METHOD_HEADER. But it (and all the other ones that take an argument) need to have a clause attached to them. As well, there could be multiple headers, leading to errors.

Motion todos

Implement rotation style in turnR and turnL
Actually turn the image in turnR and turnL (maybe can be applied in Canvas.paint?)
Implement bounce()
