[Kde-games-devel] Bugs (showstoppers?) in KGoldrunner

[Ian Wadham]

Re your backtrace: I think KGrGame::newGame (-1, -1) is getting
invoked prematurely in your environment, i.e. after the first resize event
but before the second resize event.  After that it would be all downhill.
See items #13 to #11 and #7 to #5 below (reading backwards).

Please could you put a kDebug() trace in KGrGame::newGame to
confirm this idea.  You should always get that trace, on stderr, whether
or not you have set the source to ignore the first resize event.

Cheers, Ian W.

Appendix:
kgoldrunner.cpp does a queued metaCall to KGrGame::newGame,
just before it exits.  The idea is to let the main window finish its own
deferred events, then load the last level played (or Tutorial, level 1),
behind the quick start dialog.  Because you cannot pass parameters,
newGame gets default parameters (-1, -1) for game and level.  It
then uses the config values which were retrieved during KGrGame
construction.

In your case, the saved game and level were "sot" level 0.  That is
the "ENDE" screen (Game Over), which is handled as a special case
by loadLevel().  I tested that case on my setup, using the same theme
as you (Geek City), and it worked fine.

KGrGame::setBlankLevel() is, I agree, a rather suspect, palaeolithic
piece of code.  One might almost say pre-Cambrian.  It goes back
to v0.1 days.  "for (int j=0;j<20;j++)" ... Ugh!  I used to kick bums for
writing absolute numerics in code.  That was in 1968 ...  Now you can
see why I want to re-write the game engine.  Nevertheless, I do not
think setBlankLevel() is the culprit here, unless you are somehow
getting into Edit mode prematurely ... that would do a view->paintCell() ...
