00:46 kaeza joined #minetest-dev
00:48 Zeno` paramat, is there a function for finding the inside surfaces of caves?
00:48 Zeno` And if not is this something that's practical (well, rather do you think people would use it)?
00:49 Zeno` I've written it in Lua of course, just hoping I didn't miss an internal function somewhere
00:53 betterthanyou710 joined #minetest-dev

01:12 paramat the large and small caves of mgv6, and the large caves of all other mapgens, have 'gennotify'
01:13 nnnn20430 joined #minetest-dev
01:13 paramat which records a position in the cave
01:14 STHGOM joined #minetest-dev
01:14 paramat but gennotify doesn't record positions for the 3D noise tunnels
01:14 Zeno` hmm ok
01:14 paramat because they're continuous i guess, there is no one significant point
01:15 Zeno` yeah
01:15 paramat there is a PR somewhere that extends gennotify to notify of the massive caverns in mgvalleys
01:15 TC02 joined #minetest-dev
01:15 Zeno` yeah valleys is what I'm looking at actually
01:15 paramat anyway, extending gennotify would be the way to do it
01:16 paramat i think the PR was by duane-r
01:16 paramat at least the massive caverns have significant positions
01:17 Zeno` https://github.com/minetest/minetest/pull/3648
01:17 paramat yeah
01:17 Zeno` hmm
01:17 Zeno` I might re-open that
01:17 Zeno` not sure yet
01:17 Zeno` by reopen I mean adopt the code
01:18 paramat the implementation could be better
01:18 Zeno` not sure. Have to do some tests
01:18 paramat simpler and faster would be good
01:19 Zeno` I'm not sure it does exactly what I want but locating large caverns first might cut down on how many nodes Lua has to iterate over
01:19 Zeno` not sure... looking at it
01:19 paramat the other gennotifys return a very rough position, from which mods can add their own code to locate a useful position in the structure, so the gennotify position only needs to be very rough
01:20 paramat i think that was my objection to duane's method, overkill
01:22 Zeno` possibly yeah
01:22 Zeno` I'm going to have to use voxelmanip anyway so really I just want to know if there is a large cave or not (and the location of some random position in that cave)
01:22 Zeno` I might keep going with just doing it in Lua for now
01:23 Calinou joined #minetest-dev
01:23 Foz joined #minetest-dev
01:23 eeew joined #minetest-dev
01:23 Hijiri joined #minetest-dev
01:25 paramat also of course, the massive caves are only in mvalleys, which is fairly experimental, gennotify is more for more standard caves
01:26 Zeno` yeah
01:38 STHGOM_ joined #minetest-dev
01:50 jordan4ibanez joined #minetest-dev
01:50 jordan4ibanez How would I go about turning a .mts file into a table?
01:51 paramat i think there's a serialisation function ..
01:51 jordan4ibanez It seems to spit random garbage into the terminal
01:52 paramat https://github.com/minetest/minetes​t/blob/master/doc/lua_api.txt#L2553
01:53 paramat although i haven't used that yet
01:53 paramat good videos and good work btw
01:54 jordan4ibanez Thank you very much
01:55 jordan4ibanez This is my code http://pastie.org/10988696
01:55 jordan4ibanez It is resulting in this http://i.imgur.com/nJHKJmw.png
01:57 STHGOM_ joined #minetest-dev
01:58 paramat hm
01:58 paramat can't access your paste atm
01:59 paramat yes i can
02:01 paramat could be a bug i guess, but i'm not totally sure the correct way to use this
02:01 paramat could you open an issue in engine with this info?
02:02 paramat at least then we won't forget
02:02 paramat any better with use comments false?
02:05 Wayward_One joined #minetest-dev
02:05 paramat hang on, shouldn't you set the format as lua?
02:07 paramat yes try "lua"
02:08 paramat no wonder you got nonsense :]
02:11 jordan4ibanez Oh there we go, I thought that was the schematic input! Thanks paramat
02:12 paramat good
02:23 paramat wow torches are super bright now, no one will complain about dim torches again. and yes i'll get used to them

03:15 jordan4ibanez Now there is a new hurdle, there's no way to convert http://pastebin.com/raw/qVV1ixWm to a table that I can find in the api
03:16 sofar which schematic is that?
03:16 sofar jordan4ibanez: isn't that e.g. https://github.com/minetest-mods/sa​veschems/blob/master/init.lua#L324 ?
03:17 jordan4ibanez sofar: Yes
03:17 jordan4ibanez Wait if there's an mts_save is there an mts_load?
03:17 ShadowNinja joined #minetest-dev
03:17 ShadowNinja joined #minetest-dev
03:18 jordan4ibanez I am having a hard time understanding how schematics function
03:19 paramat isn't that already a table though?
03:19 jordan4ibanez paramat: When you serialize it from the .mts file it becomes a table written in a string
03:22 paramat aha
03:23 paramat lua may have built-in functions for converting string to table
03:34 paramat so-far and i have worked with schems a bit so feel free to ask, but best discuss in minetest channel as it's not dev
03:51 Zeno` the only schematics I've worked with I generated from a hacky C program I wrote heh

23:03 Zeno` hi
23:04 Zeno` I get this lighting glitch http://tinypic.com/view.php?pic=2isijnr&s=9#.WHQVkGcvA18  in 0.4.15 release (not my screenshot but I see the exact same thing)
23:04 Zeno` But I don't get it using HEAD
23:05 Zeno` was there a deliberate fix for it (I can't see any) or was it one of the other light/rendering related commits that accidentally fixed it
23:05 Zeno` those rendering issues are quite common (using 0.4.15) on that server I've been told
23:05 Zeno` and it's pretty ugly for a release version of the client ;)
23:06 sofar any mods?
23:06 Zeno` server side? yeah I suppose
23:06 Zeno` but why does that affect the client and behave differently in 0.4.15 (glitched) than head?
23:06 sofar moretrees?
23:06 Zeno` Shara?
23:07 Zeno` it looks like moretree yes
23:07 Zeno` I can join again if Shara doesn't answer
23:07 Shara Hello
23:07 Zeno` I don't get why I don't see it in HEAD though.
23:07 Shara There is no moretrees on that server
23:09 Shara It's a valleys mapgen server. Different trees on there are from ethereal.
23:09 Shara Which I heard did not have the same lighting issues as moretrees.
23:10 Zeno` I guess I could bisect it :3
23:10 Shara sofar: Are there any other mods that are known to possibly cause it?
23:10 Zeno` i hate bisecting when I have to join a server to see the issue though heh
23:11 Shara Zeno, poke sniper for access to the server if it helps.
23:11 Zeno` It won't help... it's client-side for sure
23:11 Shara Boo then :(
23:11 Zeno` well, at least the glitch being hidden if not fixed is client side
23:12 Shara Yea, but not many players are running dev version
23:12 Zeno` I know :(
23:13 paramat looks like a moretrees lighting bug
23:13 Zeno` and it's ugly for a release version
23:13 Shara paramat: I know, but there is no moretrees there.
23:13 Zeno` paramat, but why does the glitch not show in client HEAD (but it does using release 0.4.15)?
23:13 paramat oh, not moretrees then, it could be caused by a sapling growing
23:14 Shara Even default saplings?
23:14 paramat yes sometimes
23:14 Guest30186 joined #minetest-dev
23:14 paramat that's how bad bulk node light updates are
23:14 Zeno` paramat, which commit since 0.4.15 fixed the glitch do you know?
23:14 paramat there's a PR that might fix these bugs
23:14 Zeno` paramat, it's already fixed in the client
23:14 paramat afaik there have been no kight fixes since 0.4.15
23:15 Zeno` somehow
23:15 paramat (light)
23:15 Shara It's excessive on this server for some reason. Few messages every day asking me to fix them.
23:15 Zeno` since I don't see the glitch using HEAD
23:15 Zeno` but I do with 0.4.15
23:15 paramat ah so client version affects what you see
23:15 Zeno` yeah :)
23:16 Zeno` It's not my server, so nothing is changing server-side. Just which version of the client I use
23:16 paramat weird
23:16 Fixer joined #minetest-dev
23:17 Shara I suspect paramat is right about saplings though. I think every dark area I saw overlapped trees
23:18 paramat you would think that the light values there are stored in the world, so why a shadow dependent on client?
23:18 Zeno` I'm going to bisect to see if I can find what accidentally fixed it
23:20 paramat i can't see any obvious commits that would change this
23:21 nrzkt Zeno`, https://github.com/minetest/minetest/commi​t/094a5a73d3b9817d07c52754749f0828c4005b8c ?
23:22 paramat the light curve, i can't see how though, but maybe
23:23 paramat plus that's clientside
23:23 nrzkt guys, what about removing this tag ? https://github.com/minetest/minet​est/releases/tag/sapier-20120115
23:23 nrzkt https://github.com/minetest/minetest/re​leases/tag/20120204_luaentity_allfaces
23:23 nrzkt and this
23:23 nrzkt https://github.com/minetest/minet​est/releases/tag/sapier-20120207
23:23 nrzkt these tags doesn't match any real version scheme
23:23 Zeno` umm
23:24 Zeno` err
23:24 Zeno` $ git bisect good b387f95; git bisect bad 231ac33
23:24 Zeno` Some good revs are not ancestor of the bad rev.
23:24 Zeno` git bisect cannot work properly in this case.
23:24 Zeno` Maybe you mistake good and bad revs?
23:24 Zeno` :-o
23:24 Zeno` what's going on there?
23:25 nrzkt paramat, Zeno` okay for removing previous mentioned tag ?
23:25 paramat erm not sure
23:25 nrzkt maybe 0.5.0-dev branch too
23:25 STHGOM_ joined #minetest-dev
23:25 Zeno` sofar, can you try that bisect with your repo?
23:25 Zeno` sofar, to rule out my repo being corrupt or broken somehow?
23:26 Zeno` don't finished it... just see if it starts for you :)
23:26 Zeno` s/finished/finish
23:26 paramat the tag names may be weird but those are still actual releases
23:27 paramat so i feel more input needed
23:28 paramat bu then, they are old and all 0.4.dev
