Yes, I was referring to the multiple sprite work. Changing the graphic
is really simple compared to it. Of course, there is the issue of how

Looks interesting. But maybe it is too complex? Not sure, if it can be
made simple to the user and complex for us I am ok with it.

Have a look on how we do in the games, using the svg ids to identify
the elements. We could use a translated name for the theme, for
For this to work you will have an egyptian.desktop metadescription of
the theme, and this would be translated automatically by the existing
infrastructure in KDE. In this .desktop file you could also list the
element names. It would look like:
Scripty takes care of extracting these and exposing it to translators,
and they are regenerated from the .po files. So eventually it turns
All you have to do in KTurtle is to get the localized string for the
Name key, and it will automatically work.
Notice that I would also add the ability to setsprite, not only
settheme. So it could be:
setsprite 1, "Pharaoh"
setsprite 2, "Crocodile"
... and make them run into each other :)
Niels, I remember we discussed multiple sprites last year, but do not
remember the conclusion. I have a vague recollection of Cies not being
too enthusiastic about it, but not opposing it as well. Do you
