First draft of integrated map editor UI
Removed imports pointing to unexistant files (the imported classes were
not even used anyways).
Initial steps for custom tutorials/rooms taken. Can now add custom sign
to room type by adding a tip() function to the specific painter and
placing the sign (see HealthWellPainter as an example). Tutorial floors
also have hardcoded which special rooms appear on them (these specials
will be changed to custom tutorial specific ones as progress is made).
Added logic for specifying/displaying prompts that appear each first
time a specific tutorialroom is entered (only 2 tutorialrooms exist so
far).
Prototype tutorial floor1 complete, half of floor 2 and whole of floor 3
remains (floor 4 will most likely not be customized, except if we can
figure out how to change the ending screen).
Prototype tutorial "complete".
Changed hardhitting room to have skeletons instead of gnoll brutes (the
room was too hard). Also changed positioning for sign in
healthwell/identifywell rooms, since it would occasionally spawn inside
the walls of the room.
Changed some dungeon t_chapters text + created tutorialLevelExit
(advises player to explore whole floor before exiting to the next).
