10:22 ChimneySwift   so what exactly are the coordinates sent to minetest.register_on_generated? are they the min and max positions of a map chunk? I'm getting 80x80 chunks? I thought map chunks were way smaller? what should I use to get a callback whenever a single mapgen chunk is generated?
10:32 ANAND          Mapchunk = Mapblocks * 5 * 5
10:32 ANAND          Mapblocks = 16 * 16 * 16 nodes
10:32 ANAND          Correction: Mapchunk = Mapblocks * 5 * 5 * 5
10:34 ANAND          So Mapchunk = (16 * 5) ^ 3 nodes
10:34 ANAND          or 80 ^ 3 nodes
10:34 ANAND          ChimneySwift: ^
10:38 mrchiantos     Complicate ...
10:38 mrchiantos     For a simple use.
12:01 ChimneySwift   ah that makes sense
12:31 rubenwardy     Mapchunks don't actually exist
12:31 rubenwardy     It's just a concept for map generation
12:33 ChimneySwift   huh
12:35 ChimneySwift   but if I register a function with register_on_generated, does it call that more than once per map chunk? or is the whole chunk loaded and that function only gets called once?
12:40 ChimneySwift   I guess I might just have to test it out tomorrow :p
12:41 ChimneySwift   cause I can't see of any callbacks that run on individual map blocks
15:17 Gael-de-Sailly What is the file I should refer to for the LUA_INCLUDE_DIR option?
16:15 paramat        !tell ChimneySwift 'register_on_generated' is called once per mapchunk, after that mapchunk generates
16:15 MinetestBot    paramat: yeah, sure, whatever
17:12 scr267         Is there a mod for searching a minetest map for a particular type of object and it would return a list of positions?
17:17 Krock          you'd have to load each mapblock
17:17 Krock          i.e. forceload everything
17:17 piesquared     = Superlag
17:17 Krock          an external tool might be more of what you're looking for
17:17 Krock          preferably in C/++ to speed things up
17:19 scr267         yeah, i was wondering if it would be do-able with an SQL query, (i'm using an postgresql backend) but the node data is scrambled... not sure what type of encoding its using... is it base64 or something?
17:19 scr267         an ID column which maps to another table for the object types would have been nice...
17:20 scr267         it'd be difficult to query this rapidly because there are no IDs to scan by...
17:21 sfan5          minetest uses database as pure key-value stores
17:21 sfan5          SQL queries can't help you make sense of the stored data
17:21 scr267         sfan5 yeah, thats what i saw
17:23 Krock          12 bits for each axis, whereas X contains the LSB IIRC
17:23 scr267         Krock: are you talking about the encoding?
17:24 Krock          yes
17:24 Krock          the key/ID for each mapblock in the database
17:24 Krock          maybe it has changed in postgres and redis
17:24 Krock          but is surely used in sqlite3
17:25 sfan5          doesn't postgres use x, y and z columns?
17:25 scr267         ok
17:25 Krock          yes, that's also what I suspect. Haven't seen the "postgres" part above
17:25 scr267         humm can't remember, i can go check
17:26 scr267         Yes, x, y and z columns... an example entry:
17:26 scr267         SB IIRC
17:26 scr267         sorry didn't copy and paste that properly
17:26 Krock          regarding the mapblock contents: you'd have to decompress the value BLOB (zlib) and then deserialize the mapblock contents like it's done in mapblock.cpp (MapBlock::deSerialize)
17:27 sfan5          the blob is not plain zlib, you need to decode it too
17:27 scr267         hum, ok
17:28 sfan5          https://gist.github.com/sfan5/52917a0e1338bcda2176edbc416dae60 shouldn't be too hard to adapt this script to log position and type of luaentities
17:28 scr267         hey nice, thanks

22:29 erstazi        Hello everyone! Does anyone have a copy of the LTC-4000E Traffic Signal Controller mod by cheapie? https://forum.minetest.net/viewtopic.php?t=16441
22:32 sfan5          a quick google finds it here:
22:32 sfan5          http://minetest.daconcepts.com/my-main-mod-archive/cheapies_mods/ltc4000e/
22:33 sfan5          the original repo seems to have moved here https://cheapiesystems.com/git/ltc4000e/
22:34 erstazi        Well thank you!
22:34 erstazi        I searched and searched for a week before asking here
22:35 erstazi        sfan5: do you mind me asking what your search query was in Google?
22:35 sfan5          "ltc4000e"
22:35 sfan5          including the quotes
22:37 erstazi        Ah! Ok. Thank you. I cannot wait until 0.5.0 and the the content database are out. Much of this cat/mouse chase will be resolved (:
23:15 paramat        we can't wait either :)
