Changeset 3274 for code/branches/core4/src/core/input/InputManager.cc

Timestamp:

Jul 12, 2009, 4:12:04 PM (15 years ago)

Author:

Message:

Added a few more generic parts to the input library:

• Created Mouse and Keyboard to join JoyStick and provided them with a templated base class (InputDeviceTemplated) that does most of the work (reduces quite some redundancy)
• Created InputPrereqs.h from InputInterfaces.h and destroyed the latter
• Exported InputHandler to its own file and replaced KeyHandler, MouseHandler and JoyStickHandler with the single InputHandler.
• Deleted the SimpleInputState: There is only one class now which fulfills all our needs.

In general there is now less code and the code itself has more 'pluses'. However I haven't really thrown away any feature at all.
