YANI: Wands of Light Engraving
Kassil
letters to be ethced into the ground, rather than conjuring a light field.
It could last about as long as using, say, a wand of digging...

I like this idea, but this would double the probability of a permament
writing wand, and wands of light are cheaper than both wands of digging
and wands of fire. However, the idea of glowing text interested me, so I
have written (am writing) a patch to do so.
So far the only problem I've run into is I want a glowing etching to
illuminate that square, but I don't know an easy way to make it stop
illuminating if it is /oDigging engraved or teleported, etc.
I suppose adding an engraving light source (LS_ENGRAVING) would be the
right thing to do. Tell me if I've forgotten anything (other than the
#define WEBB_ENGR_LIGHT in config.h). Please don't mind the WEBB_ in the
precompiler stuff, I'm not a meglomaniac, it just helps me remember what
stuff I added in my own code.

I like that idea.

I'm no source diver, but from what i can see, your code only
illuminates the text if the room is unlit. What would happen if you
then read a cursed scroll of light? Would the text become illuminated,
or would it just be unlit text in a dark room?

Look at what happens if you have a lit candle on a square and cast darkness.
It should just be similar to that. Once the writing gets rubbed out,
darkness still prevails.
Nicholas Aodhagan Webb
Well, as I have it right now, nothing is illuminated, even if the text is
glowing, and there are no checks if the room is lit or not. However, as it
currently stands, I don't properly snuff out the engraving for darkness.
Looks like I'll make it a proper light source after all.
