: Anyone here familiar with both ZDoom-based doom source ports and A1?
: Bluntly, I'm looking to remake M1A1's maps for ZDoom/Zandronum netplay with
: Samsara, and I was kinda curious as to some of the differences between the
: engines that could stand in my way (i.e. I can't remake M2 maps in ZDoom
: because no swimming, 4-D space doesn't exist in ZDoom etc)
Originally, Doom only supported one layer of geometry; e.g. you couldn't include the tunnels running under the main chamber in Mars Needs Women. It also only had horizontal and not vertical collision detection, so you couldn't jump from a high ledge and fly over the head of a player below. I don't know whether that's still true in ZDoom.
