source: code/trunk/src/orxonox/ChatInputHandler.cc @ 7408

Last change on this file since 7408 was 7284, checked in by landauf, 14 years ago

merged consolecommands3 branch back to trunk.

note: the console command interface has changed completely, but the documentation is not yet up to date. just copy an existing command and change it to your needs, it's pretty self-explanatory. also the include files related to console commands are now located in core/command/. in the game it should work exactly like before, except for some changes in the auto-completion.
