 Posted: Wed Jul 08, 2009 1:35 am Post subject: DirectInput/SendInput question... |
 |
|
A game I'm playing uses DirectInput for key control and I've written a program to send keys via SendInput (SendMessage() nor PostMessage() nor SendKeys() work, only SendInput).
Got any ideas on a way hook the game's DirectInput stream to inject keys so I do not have to do global DirectInput?

| It is possible using Postmessage and MapVirtualKeys, bitshift it left 16 times (<<). Not sure if it's the same for SendInput, since I never/rarely use it.

Doesn't work.

I did mine by hooking the key parser (function?) of the game. Hooking SendInput seemed way too complicated and I didn't want to put effort on this. Anyway, back the day I found this: http://www.gamedev.net/community/forums/topic.asp?topic_id=371104

LoadLibrary retrieves the address of a function as far as I know.

nwong LoadLibrary does not return the address of a function ... it returns the address to the base of a image that was either loaded or already is loaded...GetProcAddress ..does what it says..and maybe the article and code about getting input from the keyboardClass0 from a Native application could help this discussion along..

| Directly calling the WndProc works as well. I think...

BanMe, I read up on the keyboard input from a native app and it's pretty interesting.
So you would create a nativekeyboard class while injected and channel the keys in this way?

It needs some reverse engineering.. :)

Enlighten me! 
What's a good place to start?
Maybe flood the game with a specific string of keys and freeze the process, then do a memory scan for the dinput scancodes?
Maybe find the read function in dinput8.dll that is loaded into memory and do something with that?
| dnsi0 wrote: | | Directly calling the WndProc works as well. I think... |
I don't know if this will work because they game uses DirectInput which deals with scancodes on the same level as Windows ( I believe).
SendMessage/PostMessage nonsense doesn't quite work with DirectInput games; at least from my experience. Unless someone knows something I don't.

Yea. I tryed this for ms and it doesn't even call DIDevice.GetDeviceState or whatever that function was.

| Hm, I'm just trying to figure out how that method would be able to send keys to a specific application. Seems like it would just send it globally.
