Ever consider how torches don't set your ceiling aflame?
Do you wish for an alternative?
Well, now there is an alternative:
Glowing Crystals!
This mod adds Glowing Crystals - gems that emit bright light, slightly more intense than fire. These can be found underground, in a 5,000-block-thick "belt" between Y-256 and Y-5256. They are common, but not everywhere. The ore block also glows, so finding is is slightly easier.
Currently, there is only one color of crystals, and that is yellow. But, in the future I will add more colors, with different rarities and such. White will be the rarest of all, and will occur deepest.
If colored light is ever added to Minetest, I will implement such for each of the crystal types.
Crafting is trivial, thus requires no images - for torches, just substitute coal with a glowing crystal, and for blocks, make them like any other blocks of metal/coal.
Feel free to post feedback, like ideas, questions, testimonials, rants, and such - all I request is that you be polite, and, well... you know the rest.
