Guide to Hardcoded Map DS1

[Cypress]

This guide lists the hardcoded ds1 of maps and vague rules/findings related to level generation. You can use this information to change up levels a little bit. Will probably be expanded to other hardcoded parts of mapping if I can figure them out. The purpose of this guide is to make it easier to get into map editing, and to make the scope of softcoded mapping clear. If you know any weird hardcoded rules, please let me know and I'll be sure to add it in!

Colors have different meanings:
PURPLE means a unique hardcoded ds1that spawns in only one level
GREEN means a hardcoded ds1 that spawns only once in a level, but appears in multiple levels
YELLOW means a hardcoded ds1 that spawns 2+ times in a level and appears in multiple levels

NOTES:
SubWaypoints are always listed as purple, because even if the Stony Field and Dark Woods use the same waypoint by default (both use second entry of LvlSub Type 4), you can change the SubType to give each a unique and different waypoint.
All directions are given relative to the player character facing that direction from walkable space.
From the perspective of a freshly spawned player in the Pandemonium Fortress:
NORTH is facing towards the waypoint
EAST is facing towards Jamella, Halbu and The Outer Steppes
SOUTH is towards those black marble tiles with nothing on them
WEST is towards the stash, Deckard Cain and Tyrael

{todo: towns wrt transitions/river/borders/etc, act 2 outdoor, act 3 outdoor, act 4 outdoor, act 5 outdoor, those little strips of barren land that surround hardcoded ds1 and LvlSub territory. do mazes have hardcoded ds1? could at least describe the rules of their organization. not sure how outdoor levels are organized either, they seem to follow certain directions to other connecting levels based on what side you enter from}
