[Sugar-devel] Physics activity development

[Asaf Paris Mandoki]

Hi,

I would like to get started adding the play/pause button and the pin button.
Probably the next step is to integrate the activity with the journal. The
only problem is that I haven't been able to get my development environment
working. It seems there are some open issues with ubuntu. My plan right now
is to wait until the Ubuntu issues are fixed. Any suggestions for a better
setup? The only thing I have working now is a virtualbox environment where
i've been testing the activity and found some bugs. I saw a commit with the
"joystick" feature removed. Is the base code ready to start adding the minor
button changes?

Thanks,
Asaf
