Hello,
Thank you for your interest in playing the game.
Please send me your e-mail (or your preferred way of receiving files).
The wall-run system is written with C++ as an actor component class contained in:
CPPComp_Player.h
CPPComp_Player.cpp
Search for the function: PC_UpdateWallRunOmniMotion() to see how the algorithm works per tick.
There are a lot of parameters that feed in the system via PC_SetWallRunOmniMotionInfo(), you'll need to calibrate your own set of magic numbers through trial and error - at least that is how I work with the system during development.
I hope this can aid you in your project.
