Regarding Pencil: The downloads page doesn't have the latest versions. About a year or more back, there was some serious movement toward a 0.5 version before the key developer leading that push apparently disappeared. Nonetheless, the versions available at this thread work well and I use them regularly on both Linux and Windows:
http://pencil-animation.org/forum/viewtopic.php?id=1474On Windows 7, I use the build known as davidefa's build with no issues. On Ubuntu or related Linux flavors, I recommend the Zelgadis/Morevna version which also works for me without issues. [EDIT: Actually, if you're wanting the Morevna version, I'd go straight to the source to get the latest:
http://morevnaproject.org/packages/ ]
If you do use Pencil, a few tips to keep things humming along:
1.
Work with short scenes, basically one camera shot per file. For game sprite animation, this might translate to one character per file with no more than about 200 - 300 or so total frames of animation. Really long scenes in Pencil have been know to lead to some file corruption, though these newer versions may have fixed or at least mitigated that problem. I play it conservative - perhaps out of habit - and have never had a problem.
2.
Don't bother trying to use sound in Pencil; use some other approach. This may be less of an issue for game sprites anyway, since you often aren't trying to sync sound
per se.
3.
Pencil was originally designed - and still works best - as a line test or pencil test tool. It has some coloring functionality but I almost never use it. I always output my finished "pencil" animation as an image sequence, then ink and paint those in another program. If the sequence lends itself to auto-tweening, I bring it into Synfig as a guide layer. If it doesn't lend itself to auto-tweening, I bring the frames one at a time into Inkscape. The resulting inked and painted frames in either Synfig or Inkscape can then be output to pretty much any size you'd want since both programs are vector based.
One last thought: If you're on Windows and just don't like Pencil for whatever reason, I believe you can still snag the last version of Plastic Animation Paper for Windows for free. It's a nice pencil test/clean up tool though I never personally warmed up to its interface. It isn't open source like Pencil, but it is free.
Hope that helps.
Matt
