Game Development

[quote author="Bradley" date="1291441829"]Yes, if view is moved around the scene, the items positions must also be updated to hold them in a constant location in the view.[/quote] I think it may be a performance problem. But only prototype may show does performance problem really exist.

Hi, I think we are talking about two different things: One is computer RPGs and one is standard Pen and Paper with Computer support, right? And both could work on an N8.

I see ... anyway, that's not reported in the documentation clearly. T.

Hey thanks!

Kim informed me that the issue has been addressed and is fixed in Qt 4.7.1

I had checked it, even it points to dead links.

Sounds intresting, i have some free time after work

Hi have You tried QGraphicsView::NoViewportUpdate. I found that this method brought me the biggest improvement when it came to my games FPS. I don't know what the scope of Your game is but if it runs using QGraphicsScene::advance() this might work the same way for You. Ok now that I started to paint an nonblnak background NoViewportUpdate stopped being such a good idea. Please ignore my previous statement.

[quote author="danilocesar" date="1285421897"]For me, The best way to learn Qt is: read the examples and the "documentation":http://doc.qt.nokia.com/4.7/index.html[/quote] totally agree, but sometimes I just feel it is so nice to just sit back and see some cool videos on Qt :)

It seems your goal is to have something as "QPixmapCache":http://doc.trolltech.com/4.6-snapshot/qpixmapcache.html, isn't it?

[quote author="Markus Liebe" date="1283256324"] However I think the wiki parsed away several modulo operators after qrand(): [/quote] Sounds like a missed copy-passed... Thank you Markus

@Johannes good one, you should probably write this up on a new wiki page

If you want to develop game "Like this":http://pc.ign.com/objects/016/016873.html You need to learn Qt Graphics Framework first, for writing graphics-engine for rendering 2D/3D sprites.

gunnar has written several excellent articles about QGraphicsView and performance.
