Game Development

This is what I found when I started working with Boost. I did some basic math and figured that I wouldn't really gain any significant performance improvements over using my own code.

Of course, I am running this code on a very small set of data. At the most, some of the datasets will only contain perhaps 100 elements. If I were coding against a very large (and/or complicated) set of data (i.e. pattern matching across thousands of elements is a good example) then I would rethink my using Boost.

Another thing that is nice for games is some way to play sound effects, such as short wav files. Low latency, easy to use is key here.

Support for spritesheets (aka. texture atlases) would also be nice to speed up loading lots of sprites.

Even I am finding it difficult to get a copy of this book at my place.

Hi Wajahat,

the link I posted points to uic documentation, uic is the User Interface compiler, which creates source code from designer xml.

Again the link: "uic":http://doc.qt.nokia.com/latest/uic.html

Hello xsacha, thanks for the link, I'll be sure to keep it updated when possible. The size of the company doesn't matter as long as they're making or made a game with Qt, it can be an indie group as well.

EDIT: There is also "a thread":http://developer.qt.nokia.com/forums/viewthread/945/ about that post.

As far as I know, you should override the paint event to a null function and do your rendering from another function.

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.

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.

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?

However I think the wiki parsed away several modulo operators after qrand():

Sounds like a missed copy-passed... Thank you Markus

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