KDE Games Taking Shape for KDE 4.0

On May 1st, the KDE games developer community held its monthly IRC meeting. This time the major topic was discussing which games would stay in the kdegames module for KDE 4 and which ones would have to be removed because they don't meet our self-imposed quality standards. Read on for a discussion of this decision.

Our quality standards focus on having resizable, scalable interfaces as modern computers
now feature high resolution screens, and having non-resizable games decreases their usability, so now most KDE games use SVG graphics or similar techniques to achieve this functionality.

Over the KDE 4.0 development timeline, KDE games has welcomed two new additions, KSquares a
KDE implementation of the paper "squares" game and Kiriki, a Tali dice game.



Unfortunately, there are around 10 games that did not made the cut, mostly because
no maintainer was found to work on the KDE 3 to KDE 4 transition.

  • Atlantik
  • KFouleggs
  • Klickety
  • KPoker
  • Kenolaba
  • KAsteroids
  • KSnake
  • KSokoban
  • KJumpingcube
  • KTron

If any of these games is on your list of favorite games, join us and start working on it so it makes a star comeback in KDE 4.1.

For more details, read this commentary from the kdegames module release co-ordinator.

KDE needs a way to _systematically_ get rid of the ugly, redundant borders that spoil the visual aspect of many of its applications. Just compare the double border (BAD!) on the KReversi screenshot:


with the clean, borderless (GOOD!) play are of KBounce:


I totally agree.

Also, imho, some of the options in the Lipstik style for KDE 3 should be default in the default KDE 4 style (oxygen?), such as not drawing seperators and handles, and not drawing a status bar frame. This along with application creators cleaning up the toolbars would give KDE a much cleaner look.

Just my two cents. And if it's not default, atleast it's customizable. Thats what I love about KDE. Keep up the good work! :)

Yup, the customizability is a winner. Especially that I like the borders. Gimme more of them in KDE4, for a nicer look! :)

This is getting a little off-topic, but speaking of aesthetics...

Is there any convenient way to make a group of Qt/KDE toolbar buttons (I wouldn't know if KDE provide their own toolbar/tool button widgets) all take the width of the largest button in the group?

Given that most toolbar buttons are quite narrow anyway, this wouldn't usually increase the width significantly. I just find that a group of buttons of slightly different widths tends to stand out in a very bad way - does anyone else feel this way?

I agree. It's a small point, and I'm sure it could already be done on a case-by-case basis, but it would be neat to have this happen automatically. Probably quite tricky, too...

totally agree !!

I agree, specially when scrollbars are involved.

there is no automatic way to make these borders gone. i'm quite sure the borders in this article are mostly added by developers on purpose.

the real problem is that currently every game in this article has its own way to do the borders ;). so thats something for the hig.

however, i hope thats because the apps are still work in progress, and that the kde-games team aims for a consistent look of their module, and kde in general.

No, that is not the case. The explanation here is that the view in KReversi is housed in a scroll area, and scroll areas have borders by default. You have to add additional code ( not very much, only one line ) to turn it off. I just committed a patch to do that. In fairness to the developer(s), they are spending their time on the important functional points of the application that matter - in this case the game logic and artwork. These little fit and finish tweaks are a good opportunity for new coders to contribute. You don't need a very detailed understanding of C++ either.

Using the Cleanlooks style provided with Qt4 ( a copy of the Gnome Clearlooks style ) produces a more attractive interface.

i see you've made 16 commits so far today providing such fit and finish improvements to the games. awesome! thanks robert =))

> scroll areas have borders by default.

Would it be possible to change the code of the scroll area class so that that it only shows the border _if_ the scroll itself is visible? If this behavior occurs by default, the application that incorporates the scroll area doesn't have to care about when to place the border (although it would still be able to override the default behavior if it wants).

by Boudewijn Rempt (not verified)

Removing borders is not hard. It's something _you_ can do yourself. Just run through the kde4 applications, and whenever you notice an ugly border add the single line of code that turns the border off and send of a patch to the maintainer. It's a great way to get involved and grow beyond an anonymous coward into a valued member of the community.

by Casper Boemann (not verified)

Borders should NOT be removed

At least not like that. Don't go about making such decisions in the application as it affect every style.

Instead ask the style developer of your favourite style to not draw borders in the scrollview. That way every program will be fixed at one, and you you don't remove borders from styles that actually want it.

The problem is that some scroll views need borders, others look better without. This has to be decided on a case-by-case basis.

My gut feeling is that trying to do this in an automated way in the styles will not produce the best results.

by Aaron J. Seigo (not verified)

we already have proof for this in kde3 where various styles try various things with borders resulting in various apps looking alternately bad or good depending on which app and which style. =/ so i have to agree with you here.

Wow that's nit-picky, the kde 4 screenshot for reversi is a vast improvement over the previous version.

by Mathieu Jobin (not verified)

I like the fact the KBounce is not resizable and the overall new layout is nicer. but the artwork is really uglier and darker IMO. I wish the same artwork as 3.x would be available in SVG.


the dark and roundly shaped background is horrible

by Karsten (not verified)

What is about Knights?

by Louis (not verified)

As far as I know, Knights is not a part of KDE Games. It is a great chess game though, and I hope the Knights team does a conversion. Does anyone have any inside info on this one?

by TMG (not verified)

Looks like Knights is almost dead, seems like the last activity was from 2005. This is a real pitty, it was a nice chess game.


by liquidat (not verified)

What is about ksudoku? I thought someone wanted to shape it up for KDE 4?

by Matt Williams (not verified)

It's been moved to kdereview to be tested etc. If all goes well, it will be moved to the kdegames module in time for KDE 4.0

by liquidat (not verified)

Thanks for the answer.

by Robert Knight (not verified)

I'd like to congratulate the kdegames team on their work for KDE 4 so far.

Along with many of the kdeedu applications, the KDE 3 / KDE 4 difference is night and day.

The swish new artwork in particular looks great.

If I may insert a request, it would be helpful to have an overlay or some other quick-to-access help screen which explains what a game is and how to play. Opening up and reading the manual is a bit of a chore to do when you are after a ten-minute distraction. Thanks again :)

by Aaron J. Seigo (not verified)

iirc, there is a tutorial mode for one of the games and the intention is to add tutorials to the other games over time as well. this should do what you want and would be available from the same opening screen overlay that offers to start a game =)

by Troy Unrau (not verified)

Hey, nice article. *virtual high five*

I like when modules are cleaned up (waves at dannya and his kdeartwork efforts) so the improved quality of the kdegames module is good news for KDE in general, as it's one of the first things new KDE users will look at, especially if they are not net connected.


by MamiyaOtaru (not verified)

I find myself playing ktron a lot. It's a good distraction that is over quickly. Hopefully a maintainer could be found, but if not it's understandable to me, as I wouldn't have the time or motivation to do it myself.

by matthews (not verified)

IMHO armagetron is a lot nicer I would rather they took the time to work with armagetrons developers to properly intergrate and update an existing game than waste efforts on an older title that needs far more work. I'm sure if you look around you can find many fitting games that could be worked on and then shipped with kde.

by MamiyaOtaru (not verified)

Sure armagetron looks nicer. But it misses the feature of ktron that attracts me: over quickly. Armagetron is a bit more involved, and not as good a way to blow off a little steam for a minute or two (or 30 seconds). Navigating armagetron's menus takes almost that long ;)

It's too bad that there seems to be too little interest in Klickety. It's the game my gf loves about Linux...

by Knut (not verified)

That's funny, Klickety is the only game my wife cares about. :-)

by Ian Wadham (not verified)

AFAIK Klickety will survive in KDE 4.0 as a theme in KSame, which is a very similar game. There was a thread about this recently in the KDE Games mailing list.

by esomer (not verified)

That's really really sad. Klickety is also one of my favourits (if not even THE favourite). Hopefully somebody can and will take care of it.

Kind regards


by Paul Broadbent (not verified)

Ksame is a very similar game, and that is alive and well for KDE 4.
There will be no klickety for 4.0 unless a maintainer appears out of nowhere in the next couple of days and starts getting it into shape. And that's pretty unlikely I'm afraid.

by Jan Vongrej (not verified)

But maybe someone wants to do that =]]]

Same tired lame ass games now with a pretty face.

Linux gameing is never going to go anywhere with these passing as "games"

by Martin (not verified)

Well, it sure beats minesweeper and/or solitaire:)

by Chani (not verified)

actually, I miss minesweeper. there must be a linux version somewhere... time to find it!

by Torsten Rahn (not verified)

... was this lame ass troll meant to pass as a "comment"?

by Aaron J. Seigo (not verified)

these are amusements and distractions, not "games" as used in the context of "the gaming industry". there are a couple types of games: simple, fun things to play and full-on entertainment. the latter are more akin to movies and novels, the former are more like solitaire, soduko and crosswords. in fact, that's often where the source material comes from. =)

by Thomas (not verified)

yeah.. the gaming industry is not motivated to do something about Linux. I could not care less, because 95% of those "games" are like glossy paper. Looking shiny but little substance.
Try playing bzflag with your mates. Trashy GFX, looks like crap actually, but loads of fun for hours. I don't want the game to provide complexity, I want the game to be made of simple rules to built the basis for some complex gameplay.

by Bert (not verified)

As I understand all that is needed is a KDE4 development plattform. But as long as pre-alpha nothing will happen. How does porting Games from KDE3 to KDE 4 work? What are the differences and what time does it take per game?

by superstoned (not verified)

Many distributions already have KDE 4 packages for developers, and when alpha 1 is released, many more will do so (I happen to know a bit about that ;-)).

About the porting of the games, my impression is that it's some work, but not too much. It seems pretty doable, which makes sense, as the games aren't that big. Help of artists is important, though, as you will need some help in the art area for nice, scalable graphics.

by Paul Broadbent (not verified)

The biggest work needed to port games from KDE 3 to KDE 4 is changing them to use Qt 4 rather than Qt 3. Other than that there are a few other upgrades which are being added to all appropriate games like resizable, scalable interfaces and theme support.
With regards to time, it really depends on the complexity of the game. The change to how Qt 4 handles graphics is quite significant.

by MechR (not verified)

Whenever I see preview pics of KDE4's new game graphics, the one thing that keeps bugging me is the blocks, particularly when they're in large groups. Maybe it's the dark edges/color, the identical lighting, or the way they leave gaps when stacked, but in a word, they don't look "real" at all. It's kind of distracting...

by Joseph (not verified)

I agree with you, I don't like very much the blocks in kbounce (my favorite game of kdegames) and katomic. I think thee border of they could be thiner...

by Morty (not verified)

This is one place to help improve KDE where neither programming or creative artistic skill are needed. The graphic are just SVGs and as good as finished, only minor modifications needed. So why not try tweaking it yourself and apply that last bit of polish making it better. That way the games developers/artist can consentrate on more pressing matters, like porting the rest of the games. While you improve it from decent to perfect :-)

by Peter (not verified)

One of my favorite KDE3 games is Kolf. Could anyone post a screenshot of the KDE4 version?

by Paul (not verified)

No :)
The new Kolf artwork is currently "programmer art" made by me, so although it looks better than KDE 3 kolf it has yet to had much work on it from anyone with any real artistic skill. Don't worry, this will happen before the KDE 4 release, but there is little point showing you a current screen shot as there are likely to be big changes between now and October.
Of course if you are desperate to see it you could drop me an email, but I don't want to post anything public yet.

by Peter (not verified)

Ok, I'll be patient :). Rock on, though, Kolf is much-needed diversion ;-)
