They were meant for UT3, not UDK and won't work properly with the UDK. I share the fundamental code I use in the comments to my prototype video. You're free to use that code, but otherwise no, I don't just hand out work that took me a long time to figure out
I'm trying recently to add a grappling gun into my game, it's a school project, and i've seen that you still remain active on the foruns. I've seen your approach, tryi'd already some code (i've manage to download the source of http://forums.epicgames.com/showthread.php?t=687517) and tryi'd also this version of another user (http://forums.epicgames.com/showthread.php?t=681244), but this solutions are "cooked" (full source code is not available) and i can't put them to work, there are always problems (crashes, functionality broken, etc). Sow i'm here to ask, if you could share your code with me. Will apreciate.
One note: i'm working on UDK, i don't now if the versions of G.R.A.P that i've manage to download are for this version of "unreal". I'm guessing that you developed this prototype in UDK.
Thanks for your time,
Will wait for your answer.
