source: code/trunk/src/orxonox/chat/ChatInputHandler.cc @ 11684

Last change on this file since 11684 was 11083, checked in by muemart, 9 years ago

Fix some clang-tidy warnings.
Also, Serialise.h was doing some C-style casts that ended up being const casts. I moved those const casts as close to the source as possible and changed the loadAndIncrease functions to not do that.
