About
RLX is a portable, free-software graphical roguelike engine written in
Emacs Lisp. The system provides the basic nuts and bolts required to
build graphical roguelikes:
-
Graphical tile map display engine with alpha transparency
-
Turn-based action
-
Objects can be scripted in emacs lisp, and can have arbitrary
properties attached
-
Pluggable game modules, just like a real console
-
Basic AI support and pathfinding
-
Line-of-sight and dynamic lighting
-
Heads-up-display (HUD)
-
Terrain generation and pattern-based map synthesis
The first RLX game is called Void Mission. It's a sci-fi roguelike
influenced by all the oldskool stuff I used to play as a kid. I use it
to test RLX, but it is also my attempt to (eventually) redefine the
boundaries of what is possible in a roguelike, and hopefully to create
the best sci-fi roguelike ever!

This looks up the same row every time… instead i should try mapc or
something, loading each row just once.
