source: code/branches/network/src/util/Math.h @ 1455

Last change on this file since 1455 was 1446, checked in by landauf, 16 years ago

merged console branch into network branch

after several heavy troubles it compiles, but there is still a bug I couldn't fix: orxonox crashes as soon as one presses a key after opening the console… maybe someone else sees the problem?
