more adding collision than fixing it

the current method i use for triangle collision would not work on anything if it was angled straight up, so i have to make a new thing for it. it's going... interesting

if you do something weird at the edge, you can sometimes get teleported randomly, and you can also phase through the wall with the right inputs, although I'm not terribly worried as it's quite difficult to perform either

i will still try and fix them though and hopefully finish triangle collision finally, then i can move onto more enjoyable stuff
