Yes, it was pretty difficult, but I just about had it, but having to respawn and attach weapons at each phase added a level of complexity that was not good lol.
So I went back to the old way I did it initially and have that working currently. It looks about as smooth as I could get it with free animations that seems like their locations were not level. I would like to write a tutorial on it in the near future.
What was throwing me off is there was a very careful way I had to use do once nodes in order to control an event tick feed.
I ended up putting all the logic of the climb inside of the Platforms bp so it in essense controls all aspect of the climbing.
