Instead of hardcoding the lava terrain change in core, if the stairs
are created in a fixed location, force the terrain to room floor first.
Move the surrounding lava changing to room floor to the Val-goal lua
file.
placed on lava spot on Valkyrie goal level
Reported by k2, arriving at the final level of the Valkyrie quest
can issue a recently added impossible
| mkstairs: placing stairs up on molten lava at <68,13>
The report said it was easy to reproduce, but it took me multiple
tries (so not hard to do, but not a sure thing on any given attempt).
The stairs on that level are placed at specific coordinates that
are outside the pre-mapped area, so there's no guarantee that their
spot will be suitable for stairs. The underlying terrian changes
from lava to stair, but only after the warning about molten lava.
This hack solves that particular level but is not a general solution
for this type of thing. When about to make stairs on a lava spot,
change that spot to normal floor first. Plus 50:50 chance to change
each adjacent lava spot to floor too so that there's decent chance
for some elbow room upon arrival.
Also, turn the no-flip attribute off for that level so that 'fixed'
location of the stairs can occur in four different places.
Fixes#730
Game is playable, and should compile on linux and Windows.
Assumes you have a lua 5.3 library available.
Removes level compiler and associated files.
Replaces special level des-files with lua scripts.
Exposes some NetHack internals to lua:
- des-table with commands to create special levels
- nh-table with NetHack core commands
- nhc-table with some constants
- u-table with some player-specific data (u-struct)
- selection userdata
Adds some rudimentary tests.
Adds new extended command #wizloadlua to run a specific script,
and #wizloaddes to run a specific level-creation script.
nhlib.lua is loaded for every lua script.
Download and untar lua:
mkdir lib
cd lib
curl -R -O http://www.lua.org/ftp/lua-5.3.5.tar.gz
tar zxf lua-5.3.5.tar.gz
Then make nethack normally.
