Changeset 1344 for code/branches/input

Timestamp:

May 21, 2008, 6:26:15 PM (17 years ago)

Message:

• added scroll wheel support
• improved mouse input handling
• added support for mouse input derivation (allows to use the track stick like a joy stick)

About the new key binder in general:
You can assign any button/key/axis any combination of command strings the way you want.
When using simple commands (shortcuts) without parameters depending on the input, there are 3 keybind modes: OnPress, OnRelease and OnHold. For the case you assign such a command to a mouse/joystick axis, the input is translated to switch-like behavior (can be configured by feeding ButtonThreshold argument as ONE key binding).
With parameter controlled commands, keys are simply 1 or 0, axis are of course continuous. There are two ways a command can expect a value: relative or absolute input. For instance the joystick axis state (-1 to 1) is an absolute value, mouse movement is relative. Once again, everything is translated in the right way.
There's a lot more to explain, but I guess I'm gonna write a wiki page for that…

one last note: I haven't yet changed the way input is handled in the space ship. I shall do that after the merge tomorrow.
