source: code/branches/kicklib/src/libraries/core/command/ConsoleCommand.cc @ 7957

Last change on this file since 7957 was 7861, checked in by landauf, 14 years ago

added function to KeyBinder which allows to change the keybind mode (OnPress, OnRelease, OnHold) of a command which is bound to a key.
enhanced ConsoleCommand (+Manipulator) to use this feature.

input system experts, please review :D
