Woohoo [grin]



That was a lot of hard work.

Firstly, I had to switch to using DirectInput rather than responding to WM_KEYUP and WM_KEYDOWNs, since it felt a bit rubbish that you couldn't define the ALT keys.

Then I copy-pasted the entire DIK_* list from the MS DirectInput SDK into a text file and removed all the commas.

Next I wrote a program to read in this list and output a C++ file that, when compiled, produced a text file with the actual numeric value of each DIK_* along with the DIK_* next to it on a line.

Then I removed all the DIK_ bits, took out all the Japanese and weird keys and renamed each key with a meaningful name.

Then I wrote another program that took in this new file and spat out in my config format. I then wrote a static lib that wraps the DirectInput keyboard stuff and also loads a configuration file that names each key based on its index in the DirectInput keyboard array that you retrieve.

Bingo bongo, done. Not only can you now define keys and get a string onscreen in the menu, but since you can also search my CKeyState object by text name for the relevant code, I can store the key options by name in the udo.cfg file:

; Udo system settings file; Autogenerated file - do not modify; Please refer to user.cfg for editable settingsdisplay_mode="1024 X 768"sound_on=truemenu_up="UP"menu_down="DOWN"menu_select="RETURN"escape="ESCAPE"space="SPACE"up="UP"down="DOWN"left="LEFT"right="RIGHT"fire="SPACE"

All minor details, but important ones. Implementing the menu was suprisingly easy, actually.

Never written a game with user defined controls before. Cool. Obviously if you were playing on a non-UK keyboard, you would have to provide a different keydefs.cfg file, but that's not a problem as far as I am concerned. Certainly beats messing about with GetKeyNameText().

In case it is ever of use to anyone else (or in case I lose it), here's the keydefs.cfg file. The numbers correspond with the index of each key in the array returned by IDirectInputDevice8::GetDeviceState() when applied to a keyboard.
