[Sugar-devel] Physics activity (Was: Release v3 tonight?)

[Asaf Paris Mandoki]

Hi,
Thanks for the feedback. The save/load functionality is ready and I'll
be committing soon to elements.

Brian: What is the status of the library handling? I'll have to update
elements after I commit to enable the new functions and commit

BTW, the pickling function I added to elements was almost copy n'
paste from the pybox2d testbed. I'm new to python but I think there is
something that is not finished or maybe it wasn't cleaned up about the
additional_vars in the pickle_load function. I'm not sure if that
argument should be removed.

I also have other modification suggestions that I wanted to run by you
before creating the tickets.

1. It IS possible to pin/link objects to the background (It just needs
a 2 line hack). Should we enable this feature?

2. Modify the polygon tool icon. I suggest changing it for an
irregular polygon. The icon gives the idea of a different behavior.

3. Modify the grab tool icon. Maybe put a hand shape. The current icon
is not really descriptive.

4. Make the Play/Stop button more conspicuous, maybe change its color(s).


>> Another minor modification can be to change the name of the joint tool to rope tool. What do you think?

I thought about this in my UI round, but other than tweaking the icon a little I didn't see a clear win. Happy to revise though if there's a consensus – I thought of changing the icon to several of links in a chain, but this would indicate the joint is made of flexible sections, when actually it is a solid rod with a pivot at each end.

I think the current joint icon is ok.

Greetings,
Asaf
