source: code/branches/console/src/core/Shell.h @ 1326

Last change on this file since 1326 was 1326, checked in by landauf, 16 years ago

fixed crash when displaying debug-level 4 and 5 in the InGameConsole. It works perfectly now, although it's not recommended, because you won't see much of your own input in the console any more ;)
however, performance is quite good. maybe i can improve it even more.
