PedoMan: optimizing time

riq on 2009/09/02 14:57 of Solo Solo

Since I won't be able to code during this Friday / Saturday due to PyCon Argentina, I need to "optimize" time.

Levels:

A simple SVG (inkscape) parser that generates Box2d code. (it seems that everybody is doing it)

Tiles:

No time for tiles.
I'll use box2d's DebugDrawData

Characters:

It seems that squirtle can't draw circles, it's raising an exception, so I'll use raster images.

Sounds:

cfxr

Intro:

Only If I have time to do it

Oooh, my memories of looking at the squirtle code makes me think it *should* be able to draw circles. Am I wrong?

If you want to post the exception it produces, plus the svg it's trying to load, I'll take a quick look at it for you - maybe there's a quick change can be applied to your copy of Squirtle (or your SVG?) to make it work.

There were some problems with circles in early versions of Squirtle - they should be solved by now, but it's possible that you're using an old version, or that there's another edge case that slipped through. If you can show me the SVG file that gives the exception, I can probably fix it.

@martin, @tartley:

I'm using squirtle 0.2.4

The .svg that is raising the exception is:

you can try squirtle_mod, see
http://groups.google.com/group/cocos-discuss/browse_thread/thread/0e717b55a1859b6d#
http://www.pyweek.org/d/2676/#comment-5637

The download link is
http://groups.google.com/group/cocos-discuss/web/squirtle_mod_bugfix2.zip

It is based on squirtle, has a bit of fix and extension over standart squirtle.
Comes in two flawors: squirtle classic or cocosnode style.

claxo on 2009/09/02 18:15:

by the way, the svg you pointed is displayed ok with squirtle_mod

claxo on 2009/09/02 18:35:

or, as a workaround: in Inkscape select the offending object and do 'object to path' ('objeto a trayecto'), under the 'Trayecto' ('paths'?) menu.
hint: arcs are not 100% ok in squirtle or squirtle_mod

@claxo: thanks.

Ha. When I said 'I'll take a look at it", I also typed a sentence along the lines of "although people far more qualifed to do so are present, obviously", but that got lost somehow. :-)
