06:17 sofar how can GenericCAO not have m_pitch? *tears hair out*
06:17 Hunterz joined #minetest-dev
06:23 paramat no idea
06:24 sofar apparently the server only ever sends yaw, but never pitch
06:24 sofar anyway, I was attempting to look at head rotation for players
06:25 paramat nice. merged
06:25 sofar good job
06:25 sofar I think I lost an hour figuring out what each of the [CS]AO
06:25 sofar 's are
06:25 sofar and which one I'd actually need to look at
06:25 paramat btw is it possible to place new doors using lvm?
06:26 sofar lbm?
06:26 paramat door + hidden i guess
06:26 paramat lua voxelmanip
06:26 sofar can lvm write node metadata?
06:27 paramat nope
06:27 sofar you can get pretty far. I suppose we could make the door code recognize a "metadata-less" door and assume it was placed as a closed door
06:28 sofar should be easy to test, sec
06:28 paramat it would be good to allow schematics with doors
06:28 paramat closed by default would be fine
06:29 paramat for example sokomine's villages mod  has schems with doors
06:29 sofar actually
06:30 sofar I think it's already working
06:30 sofar you have to make sure you place doors tops and bottoms with the same facedir, tho
06:30 sofar I just placed one with //lua minetest.setnode() and checked if the doors API code sets the metadata
06:31 sofar and it does, properly
06:31 sofar lemme try right-sided door, though
06:31 sofar right-hinged
06:34 paramat set node is different to lvm though
06:35 sofar yes, but set_node only sets content and param1/2
06:35 paramat ok. lvm doesn't call callbacks
06:36 sofar hummm, how can I detect in lua whether a nodemeta value is entirely missing? get_string() it?
06:36 paramat uhm i don't know =/
06:36 sofar ah, yes, that works
06:37 paramat placing doors using set node is essential, by lvm would be good too
06:39 paramat phew down to 26 PRs, now i'd like to keep it down to 1 page (25)
06:47 sofar ok, I have a patch for that
06:47 paramat good
06:47 paramat lvm and schematics can set node id and rotation, both need to be able to place doors, i would say it's essential
06:48 sofar the hidden top should be included in the schematic for best results
06:48 paramat sokomine is currently updating villages mod to new doors, you could perhaps discuss with her
06:48 sofar but it can be missing
06:48 paramat yes
06:51 sofar of course, mods using lvms could set nodemeta, and then lvm in the blocks.
06:52 sofar but, this will work for wooden doors
06:52 sofar (not for locked doors, obviously)
06:52 paramat ok
06:52 Soni joined #minetest-dev
06:53 sofar actually, it works fine
06:53 sofar can place a steel door this way
06:53 sofar it's just openable by everybody
06:53 paramat lol
06:53 sofar game#957
06:53 ShadowBot https://github.com/minetes​t/minetest_game/issues/957 -- Doors: Allow schematic placement of wooden doors. by sofar
06:54 paramat thanks
06:58 sofar why did you reopen #953?
06:58 ShadowBot https://github.com/minetest/minetest/issues/953 -- When re-loading map, map is totally black
06:58 sofar game 953, of course
06:59 paramat oh error
07:00 est31 joined #minetest-dev
07:00 paramat thinking it was open i just hit the 're open' button thinking it was the 'close' button
07:00 paramat oh it auto-closed the issue, creepy
07:01 paramat it does that when some PRs are merged
07:01 sofar must be a new thing
07:01 est31 no
07:02 linkedinyou joined #minetest-dev
07:02 est31 you can add "fixes #blabla" to your commit msg then issue #blabla gets closed when you push and you also have commiter rights for a repo
07:02 est31 its an old thing
07:03 paramat ah
07:03 est31 also works for "merge" i think, there are a couple of magic words.
07:03 sofar est31: I started looking at head animation client-side. turns out GenericCAO only stores (gets from server?) yaw, never pitch :^((
07:04 est31 of course real fun when you write "doesn't fix #blabla" and it closes the issue
07:05 est31 lemme see
07:05 sofar 623 in content_cao.cpp
07:05 sofar I can extend, obviously, new version, woohoo
07:06 sofar not that I figured out the rest yet. I can mess up rotation of players, though, that's hopeful, lol
07:07 est31 i remember a bug where the yaw is sent wrongly, turned by 90 degrees or something
07:07 sofar that's to lua
07:07 est31 bug in the protocol
07:07 est31 ah
07:07 sofar this one is to the client, and it's correct
07:07 est31 cool
07:08 est31 so, its not that big of an issue to bump the protocol version, is it?
07:08 sofar anyway, I'm out of gas, it's late, and I gotta work tomorrow. I now know where I can mess up bone rotation
07:08 est31 now that you know how it works :)
07:08 sofar well it's still weird
07:08 sofar updateBonePos is only called once
07:08 sofar UpdateNodePos is called every step
07:09 sofar not sure why. oh well?
07:09 sofar the version bump should indeed be fine
07:10 est31 idk either
07:11 Soni joined #minetest-dev
07:11 sofar it's gonna be a hack for starters to begin with. if it works as a concept I'll be happy. No rush
07:11 * sofar gives up for the day
07:11 sofar later

08:02 ShadowBot https://github.com/minetest/minetest/issues/3890 -- Update menu header image by kilbith
08:05 paramat i'd rather the spaces were removed, see my comment
08:06 Obani I personnaly prefer with spaces
08:06 Obani It's more readable and airier
08:07 Obani But I agree it would do some strange things switching to singleplayer tab :)
08:11 paramat i'd also prefer a new surface texture instead of stone, perhaps something metallic.
08:12 Obani mmh
08:12 Obani I would have seen personally something more organic with dirt, grass, trees, flowers, lianas,... :p
08:12 Obani But kinda hard to make
08:12 paramat #958
08:12 ShadowBot https://github.com/minetest/minetest/issues/958 -- Add player list, viewable by holding Tab by sfan5
08:13 Obani :o

10:00 red-001 paramat are you working on adding an on_flood callback?
10:02 paramat not yet but maybe after release
10:11 paramat but i don't like the idea of allowing water to drop nodes and would rather not bloat the liquid code with something non-essential
10:28 Elinvention joined #minetest-dev
10:51 paramat hm so actually no i won't work on it and will vote against it :)
11:24 est31 joined #minetest-dev
11:25 est31 okay noclip enforcement works so fa
11:25 est31 r
11:25 est31 but it has some problems though
11:25 est31 mostly because of failing path search
11:26 est31 and because path search is so slow
11:26 est31 it really is, searching 16 nodes takes like 100 ms
11:26 est31 thats not nice
11:27 paramat 100ms == forever
11:28 est31 yeah
11:30 est31 that path search code needs a big cleanup anyway
11:30 red-001 what is quicktune?

11:41 est31 idk, i have to do non minetest things, now, as much fun as fixing the noclip enforcement would be
11:41 est31 first I would have to understand what all the path search code does
11:43 Megaf joined #minetest-dev
11:43 est31 its not that hard, its just a bit uncommon

11:49 ShadowBot https://github.com/minetest/minetest/issues/3895 -- Make node timers more efficient by Ekdohibs
11:49 paramat nice
11:49 nore Needs review, and some more testing than just mine
11:50 Megaf Merge that please
11:50 paramat yeah i'm a little concerned about adding nodetimer crops for release, hopefully 2 weeks is enough to debug
11:51 nore Also, I did not profile it, so I don't know if is really is faster, but it should be, the speedup should be enough to balance the slightly higher constant factor
11:51 nore (2 maps instead of one)
11:51 nore So, adding a node timer is 2 timers slower as before
11:51 nore But each nodetimer step should only have complexity O(number of timers that were triggered)
11:52 est31 it should be profiled
11:52 nore (maybe * log (number of nodetimers in block))
11:52 est31 i had suggested a speedup to RBA
11:52 nore meaning that nodetimer can be decreased
11:52 est31 didnt profile it and he applied it
11:52 est31 what we ended with was master having a big speed regression in meshgen
11:52 nore est31: how do you profile it? (I've never done profiling before :/)
11:53 est31 usually you measure some code
11:53 Megaf when will this be merged? https://github.com/minetest/minetest/pull/3848
11:53 est31 how long it takes to execute

11:54 nore ok
11:54 est31 afk
11:54 nore hm, it looks like I added a bug :/
12:06 kilbith joined #minetest-dev
12:07 kilbith paramat, give me a reason why you removed the milestone on my Creative cleaning ?
12:07 kilbith it's important, i don't want to ship a least optimized code for 0.4.14
12:09 paramat ok i'll re-add
12:10 kilbith reviewing appreciated as well please
12:10 proller joined #minetest-dev
12:13 paramat no reason for removing the milestone apart from undecidedness on what is essential for release, happy to re-add it
12:15 paramat i would like to see it included for release, so that was a mistake sorry
12:16 kilbith sorry to be sensitive on that because it's my area of expertise
12:17 rubenwardy Just because something's not on a milestone doesn't mean that it won't be added before release
12:17 kilbith yes but at least i have a clear warrant that it will be shipped
12:19 rubenwardy very true
12:24 rubenwardy why is Minetest so terrible at transfering files w/o remote media server?
12:35 nore est31: so the real bottleneck is actually iterating the mapblocks: I get a little speedup, but the code is actually already very fast
12:36 nore averaging over many steps, it looks like nodetimers currently take 1/4 to 1/3 ms per step (with ~200 active nodetimers)
12:37 nore with my pull, it more like 1/5 to 1/4 I would say
12:40 est31 ok
12:40 est31 well its a speedup
12:40 est31 thats goo

15:48 Sokomine sofar, paramat: handle_schematics and mg_villages are both updated now so that they can place new doors (they use voxelmanip) if the schematic contained an old door. i'm not sure if i caught all possible setups of doors, but those i tested worked fine. the _a version of the door seems to work right out of the box; the _b version needed extra treatment
15:55 Sokomine sofar, paramat: and yes, the actual setup of the doors is done after the placement and lvm is finished; just like chests and other things with metadata. the existing door-abm can't be used due to the old nodes no longer existing

17:14 Sokomine sofar: ah. that is good to hear. so no more extra handling of _b doors necessary?
17:14 luizrpgluiz joined #minetest-dev
17:15 sofar right, if you place the two nodes with param2 to rotate them properly with the schematic, then it should autocorrect them without a hitch
17:15 Sokomine that sounds good. param2 rotatiion is handled by the mods
17:16 sofar yes, that would be in your schematic
17:16 sofar mts schematic, right?

18:04 sofar following line for function braces, same line otherwise
18:05 sofar ssieb: don't look at C++ for code style rules, lol
18:07 Void7 joined #minetest-dev
18:08 ssieb ok
18:09 ssieb I want to change the colorize command to respect the destination alpha.  A brief look at mods indicates that changing the current way it works would change how current nodes are displayed.
18:10 luizrpgluiz left #minetest-dev
18:11 ssieb Would it be ok to add an option where if the second parameter is "alpha" instead of a number, it will do what I want?  This will not affect any current mods or clients.  It will only add new functionality for new clients.
18:13 sofar is that a lua function?
18:14 red-001 colorize?
18:14 ssieb Oh, sorry, it's the ^[colorize option for textures.

22:07 sofar awesome
22:08 sofar FYi if you haven't seen this one: https://forum.minetest.net/v​iewtopic.php?f=7&t=14229. possible long read, but may be interesting
22:08 celeron55 ...assuming i can actually figure out how to move a topic
22:09 sofar "In each topic, there is an option to "Move topic" (click the dropdown next to Quick-mod tools)."

22:13 celeron55 sofar: it's called Lua, not LUA
22:13 sofar sure, lol
22:14 celeron55 this is important!
22:14 sofar fixed it :)
22:15 sofar don't have to discuss in the forums, but I'd be interested to know which items people would like to see prioritized
22:15 sofar or, toileted ;)
22:17 celeron55 well, none of them need to be toileted
22:17 celeron55 just be very wary of performance in some
22:18 celeron55 11 is something i have been wanting a long time already
22:18 celeron55 and contains a typing error
22:18 sofar 11 doesn't sound like a technically complex thing
22:19 celeron55 it clearly wants to say "server to client", not "client to server"
22:19 sofar ahh lol, yes
22:19 celeron55 yeah it's not complicated at all
22:19 sofar I've pretty much written down the whole implementation there as well
22:20 sofar just in words, not code
22:21 sofar 4 may be an issue, but I think it could be *faster* if implemented correctly
22:21 sofar 5 is really something that should be simple - just allow optional tiledef instead of "texture = "
22:23 sofar I however keep coming back to 2 being the one thing that blocks so much progress
22:25 ssieb Is it possible to use mesh objects for tool inventory images?
22:26 sofar right now, or with patches?
22:30 celeron55 sofar: what you elaborate in 2 could be a reasonable way to do the thing; people often get into all kinds of database complexness when they talk about that
22:30 ssieb sofar: right now
22:30 ssieb but I'm assuming from your response that the answer is no :-)
22:31 sofar celeron55: it could easily be done in steps, too
22:31 celeron55 and probably not even difficult; the most difficult part can be designing all the compatibility things to work perfectly
22:31 sofar ssieb: only way now is to make an entity and bone_attach
22:31 sofar ssieb: I think
22:32 ssieb I meant just in the inventory, but yes, for the wielding as well
22:32 sofar oh
22:32 sofar if you have a mesh node block
22:32 sofar like e.g. fencegate
22:32 sofar that just *works*
22:33 sofar just open the game with current git for minetest, and minetest_game, and look at the fencegate item

22:48 ssieb sofar: is that a tool?
22:48 sofar ah, no. mesh tools? never heard of it
22:50 ssieb would look nicer in the inventory
22:51 ssieb and for wielding
22:51 sofar honestly, if you've seen my list I think you'd realize how little I could care about something like that, sorry
22:52 ssieb sure, it was just a general question
22:52 nore sofar: btw, about #3895, I tested it with ~150 active nodetimers; the speedup was not very high since nodetimer managing is already quite fast, but there still is one
22:52 ShadowBot https://github.com/minetest/minetest/issues/3895 -- Make node timers more efficient by Ekdohibs
22:52 sofar ah, ok, I thought you were suggesting something for my list
22:53 red-001 joined #minetest-dev
22:53 nore I guess with ~1000 nodetimers the speedup would be more noticeable
22:53 sofar nore: the optimization is nice, it'll make the farming conversion even better
22:53 sofar with increased range for timers activating, one could grow huge fields of crops ;)
22:54 nore I could optimize it even more, to avoid iterating blocks that don't need to
22:54 nore but I'm not sure it would be very useful, nodetimers are already *very fast*
22:54 sofar tbh I don't see the current implementation as bad at all
22:54 sofar nod
22:54 nore i.e. < 1ms each step
22:54 nore whereas ABMs take ~30ms...
22:56 nore (well, I was even wondering if it would be possible to handle ABMs the way nodetimers are handled instead, that would remove quite a lot of server load)
22:56 red-001 joined #minetest-dev
22:56 nore anyway, it's getting late here, so good night! :)
22:57 sofar nore: if you want something that abuses abm's try minetest-mods/mymonths
22:57 sofar it'll make abm's overflow it's timeslice :)
22:58 nore isn't it the thing that add seasons?
22:58 nore for a mod like that, I'd rather use voxelmanip; but there would need to be a way to know which blocks are active
22:58 nore and that's something I've been waiting for for a loooong time
22:59 nore maybe I should try again to code it someday (IIRC I tried once, but failed as I was not experimented with the engine enough back then)
