Changeset 6657 for code/branches/gamestate/src/libraries/core/input/InputState.h

Timestamp:

Message:

Implemented indirect function calls for input events. It simply means that when you hit the mouse button, the resulting call stack will not include OIS nor an InputState anymore.
—> You can reload the InputManager (happens when mouse mode changes) or even modify the InputState situation (like InputManager::leaveState or even destroyState) directly now.
—> I was able to remove the indirect execution of following methods in the InputManager: leaveInputState, enterInputState, destroyInputState and reload.
