modlib VS dfcaverns

OBJ is a reasonably simple line-based human-readable file format. It's pretty easy to generate OBJs manually if you've understood how OBJs work. Here's my subset-of-OBJ "library": https://github.com/appgurueu/modlib/blob/master/minetest/obj.lua (caveat: it lacks docs).

I have a few patterns for unescaping of HTML entities lying around. Note that these depend on a rather large lookup table of named entities and a function that provides you a byte string for a UTF-8 character code; if you want to support just hex and decimal, you obviously don't need the named entity lookup, but still the UTF-8 to string.

So when I updated DFCaverns, the first thing I did was point all of those references to a single "df_dependencies" mod. Then that mod did all the heavy lifting of figuring out which game it was being run with and supplying the version of the asset that belonged to that game.

Because the magical jackhammer sounded fun, I just finished implementing it in the mineclone compatibility branch I've been working in. It's basically a point-and-click explosion maker. Results in a bit of a ragged corridor when used to dig through Slade, but given that previously you had to bludgeon your way through with much less precise TNT blasts it's still an improvement. I'll play around with it some more. One drops when a slade breacher is finished its job and self-destructs. Note that you'll need the latest versions of subterrane and mapgen_helper if you want to sync from that repository, the default method of synching git doesn't get those so you may have to do get them separately.

I kind of retired from modding for a while (just because other interests came to the fore and I was busy) but the past month or so I've renewed my interest largely because the issues list for DFCaverns got long enough to guilt me into coming back. But as I'm fixing bugs I'm finding yet more new details and features to add along the way, so the fun's come back. So strange as it may be, if you enjoy DFCaverns then by all means complain about it and tell me what it's missing. :) I could particularly use insight into its "balance", since as mentioned I don't actually play it.
