Wall-Climbing Systems.

Hello! I'm attempting to make a wall-climbing system for web-crawlers and other similar characters with that ability for my superhero mod which I'm working on, but I wasn't able to figure it out, I've searched everywhere and didn't find any answers except for a few ones (that only worked for entities but not for players), I see that this topic of wall-climbing is always one to leave unanswered when it comes to working for the player but I hope this isn't the case for me.
