It would appear that we're computing various distances more-or-less exactly in the sprite rendering process, but this is at odds with the walls and floors which -- by virtue of the linear interpolation garbage -- don't agree about where things are. The net result is that there are at least two fudge factors: - to account to for the incorrect height of the floors i shift the sprites up by 0.2 - to account for the incorrect wall distances i add 1 to the z_buffer comparison These fudges are ugly and empirical. Still to do: for more than one object we have to sort by distance first! 2021-09-01T17:05:40Z tslil clingman 2021-09-01T17:05:40Z urn:sha1:dae5c3d1e9bdbabf94f79960b2fca9a5f47b7ac0 2021-09-01T16:59:50Z tslil clingman 2021-09-01T16:59:50Z urn:sha1:6a2d132873ce7b40405a3dc000a12539fffd969b
