RECOMMENDED CONFIG: FOV: 90 Quality: 2 drawSize: 2 (1 is smooth but makes weird shapes) map height: 1-2 (depending on how spacious you want the place to be.) No, I did not use Griffpatch's tutorial. I hate tutorials. I decided to try and make my own 3D game. However... I have no idea how to make this first-person.
UPDATE ON EXPERIMENT 2: I changed it to render first-person and added a bunch of parameters. I also added rectangular filling (draws multiple lines instead of one) so we can use a low-quality raycast and it fills in the empty spots.
