How To Make A WallVault Without Using Animations. Only Code

Hey There!

I really want to know how to make a vault system, but dont have idea where to start to make this. the best reference i have for you is this outlast gameplay in the minute 6:30 when the character climb up the duct in a really cool way. (Video Down here)

The problem here is that i dont want to use animations, only code. i know that a big part of the outlast feel its achieved by the animations, i know i will lose a part of that good feeling, but i want do it in that way.

How you guys can reach results the most closest posible to the outlast climb without anims?

Thanks in advance!
