Here it is at last!
http://files.maniaplanet.com/tools/Mani ... -10-06.zip
main changes:
- Removed debug logs
- now loads all recent maps
- included campaign maps
- relay servers should now work (same way as TMF)
- a few other bug fixes. (but most of them need fixes in the client, so I'll list them once the client is updated)
I added a SetApiVersion() call, which you can call with SetApiVersion("2011-10-06").
It will remove all deprecated methods, change a few structure names (Challenge -> Map, and so on), change most callbacks names as well.
and the few methods that had an optional parameter "structure version" are also cleaned up.
I updated the "documentation" (methods.html and callbacks.html) to match the cleaned up api.
(for now I left the compatible version by default, so there's nothing to do for you.
But in the future, let's say for shootmania, I'll probably add features only to new api versions)
keep up the good work!
