Nevermind I found out that, "wall_top_right" and "wall_top_left" is what I need. I am still confused pf what the purpose of "wall_side_right" and "wall_side_left" is.
lol, if you do not want to use there is no need, I just put it because the edge of the wall would get more "clean" haha
Thanks for the info btw, I knew that sooner or later someone would notice a mistake that I did not realize
