i was working on adding sliding along walls so that my engine just feels better to use and then came to the painful realization that at angles of 0/180 you can just phase through walls because of damn slope issues (#/0)

so i get to add a new scenario to account for the specific scenario that something has a slope of infinity

also for the sliding i could have made a simpler version without needing trigonometry but because of said issues I'm not even going to bother (i already have the equations ready anyways)

rant basically
