Game patcher and launcher

Recommended Posts

Hi guys!

I've been looking for a patching tool for games that's affordable for my budget but sadly I didn't find any, so I rolled my own. Hopefully, people can find it useful.

They are 2 tools, the first is [url="https://github.com/amireh/Karazeh"]Karazeh[/url] a launcher/patcher tool that you can use to a) validate & update your game, b) launch it after it's done updating. Karazeh is pluggable with different frontends/renderers (such as Qt, GTK, Ogre) so you can use whatever feels best for you, or you can roll your own using the toolkit you're already using.

The second tool is [url="https://github.com/amireh/Kiwi"]Kiwi[/url], the one that generates the patch script which Karazeh consumes.

Both tools are hosted on github, completely free, licensed under the MIT. They're writtein in C/C++. Karazeh (the launcher) was built in a way that (as much as was humanly possible) didn't get in the way of your toolset/environment. For example, if you're using boost already, it can make use of boost threads. If you're using Qt, it can use Qt threads. If you're using neither, you can write your own thread wrapper, or run it in "threadless" mode!

The same goes for the "Renderers", by default I shipped 3 renderers: a vanilla/CLI one that's not really helpful, an Ogre3D-powered one, and a full-fledged Qt one which is good because you can easily customize/skin it... I might create a CEGUI renderer soon since I'm using it for my next game.

Anyway, I'd love to hear your input on this. I was amazed not to find such a tool already existing for, well, something less than thousands of USD !! =D

If you'd like to contribute, you can:

[list=1][*]issue tickets with features you'd like to have implemented/would need in such a tool (or just reply here)[*]tell me of things you would've done better[*]help in testing it on your own distribution, i personally use Arch Linux and sometimes Windows XP ... so I can't test thoroughly[/list]
Salam,
amireh

[b]For the gurus:[/b] I've had trouble implementing a feature in the patcher, and I'd deeply appreciate any insight on the problem. I asked the question on StackOverflow [url="http://stackoverflow.com/questions/6117222/versioning-executable-and-modifying-it-in-runtime"]here[/url] but I'm not satisfied with the solution. If anyone is interested, please PM me or reply to this thread and I'll rephrase/build upon my findings and solution.

Wow, this looks pretty awesome.

I was beginning to think I would have to code one myself but yours looks very good indeed so I think I will give it a try.

One question though , have you taken into account how to update the launcher once you have distributed it with a game?

Thank you I'm glad to hear that.

Karazeh can patch itself! I've tested this on Linux and Windows XP and it works. Windows prevents you from *modifying* the running executable, but it allows you to move it. So what I do is move the binary to the temp directory, patch it with the diff file, then move it back.

There *might* be issues with this approach on Vista/7's UAC, but I'm not sure yet that's why I'd appreciate any testing on that OS.


Cheers,
amireh
