07:29 DrFrankenstone Is there a way in lua for a node to know when a block next to it has changed (like BUD switches in Minecraft), or would this be achieved with ABM polling?
07:31 sfan5          polling sounds like a bad idea performance-wise, using register_on_placenode/dignode might be better
07:32 sfan5          (though that won't cover all possible changes, so polling is the last alternative)
07:36 DrFrankenstone register_on_placenode can probably be bent to the task
11:36 andirc8000     Can someone help me please I want a node to be destroyed with a single punch (and only one node and not the nodes behind it) so here is my modification of oneclick mod (or is it the original one (?)): https://hastebin.com/veruyoyujo.lua it works fine but it destroys sometimes 2 nodes at once
11:38 andirc8000     what If I "punched" a node with "almost infinite" strength instead? Would it still unnecessarily destroy the node behind it?
11:39 andirc8000     instead of using remove_node(pos) *
13:25 andirc8000     anyone?

15:52 greeter        greetings. got a mod's question. a friend of mine and i are both running our own servers. on his, he can dye stone bricks different colors, but on mine i can't. i thought unifieddyes was the mod i was missing but it still doesn't work. any ideas how to get that working?
15:55 Krock          greeter, craft a colored stone brick on his server and use the F5 information to find out how the node is called
15:55 Shara          greeter: half-guessing, but maybe colormachine?
15:56 Krock          that will also tell you the mod which is required to add the colored stone (usually)
15:56 greeter        ah great thank you kindly
15:56 Shara          I was going to say that, then realise it might be registering it through something, so not showing the right name :P
15:57 Shara          You can also check which mods are running on their server
15:58 greeter        i'm looking at that, but i have almost all the same mods they do, the ones that are different have nothing to do with colors
15:59 greeter        at first i thought maybe they had a more up to date unifieddyes but that update didn't work lol
15:59 Shara          Are both servers public?
15:59 greeter        no, mine is but his is locally run
16:00 Krock          also watch out for mod conflicts or errors in your server's debug.txt - maybe some dependencies weren't satisfied
16:00 Krock          i.e. mods weren't loaded even though you marked them as to-load in the world configuration file
16:03 Shara          Can I ask which is yours? (randomly curious)
16:04 greeter        i'll notice you the details. also i'll check that out Krock
16:10 Krock          Shara, it's a secret..? :P
16:11 Shara          Seems like :)
16:11 Krock          Shara, heh, looks like you've found him
16:11 Krock          ravenchat creative ?
16:12 Shara          Who knows?
16:13 Krock          Me!
16:19 greeter        yeah that's it, i just didn't want it to be construed as spamming is all, but it's no secret
16:20 Shara          I don't think it's spamming when directly asked :)
16:22 greeter        https://forum.minetest.net/viewtopic.php?id=2574 umm i think there's a problem with the images here :\
17:04 Vanta          Hey guys, I have this tiny code snippet https://pastebin.com/F37kG3CN I'm trying to decorate underground caverns with schematics, but for some reason they never spawn, though function returns true
17:04 Vanta          I mean it's just an example code
17:04 Vanta          There are 2 lines, one replaces blocks and seconds spawns schematics. Block replacement works just fine
17:23 Krock          Vanta, A problem I can see there is the mod security: If you run this code outside of the default mod, then it may not have access to that file.
17:26 Vanta          It would report that, that it can't access the file
17:26 Vanta          Instead, function finishes without any problems and returns true value
17:29 Krock          just looked up the code. it doesn't check whether the mod has access to the schematic or not
17:29 Krock          but you're only passing "vm" to the placement function
17:29 Krock          this means "data" stays unlatered
17:30 Krock          *unaltered
17:30 Krock          afterwards you're kinda overwriting the placement: vm:set_data(data)
17:31 Krock          i.e. you can't use data[vi] = foobar  and place_schematic_on_vmanip  in the same loop
17:32 Krock          ^ Vanta  (just to notify)
17:34 Vanta          Well I put data[vi] just for example, it didn't work anyway without it, anyway place_schematic_on_vmanip should overwrite that action anyway
17:36 Krock          well yes. should, but doesn't because the code tells otherwise
17:38 Krock          "data" is Lua-only and the C++ side does not update it when placing a schematic directly into the vmanip
17:38 Vanta          I see
17:45 Vanta          So I should make another separate loop that doesn't write anything to voxel manipulator, for spawning schematics?
17:46 Vanta          I mean not setting vm data and neither writes anything to map
17:49 Krock          To still get the same effect, you can 1) get the vm data 2) data[vi] = foobar in the loop & cache the positions to a new table 3) set data 4) discard data 5) loop through the cached positions
17:49 Krock          .. and place the schematics
17:50 Vanta          I see, I guess that's why people place empty nodes with schematic spawning abms instead, haha
17:51 Krock          they should rather use node timers instead of abms - it also spreads the load on the server, i.e. reduces the on-generate lag
17:59 Vanta          Big thanks for help
18:00 Krock          !next
18:00 MinetestBot    Another satisfied customer. Next!
18:59 Vanta          Another question: how can I do operations (for example cave decoration) after it's already been generated? Here is an example snippet, https://pastebin.com/vZrAyZpj
18:59 Vanta          It never passes the check if node is air
18:59 Vanta          I can only assume that at the moment of execution caves are not generated yet and everything is stone
19:20 paramat        Vanta see https://github.com/paramat/planets/blob/c325020d994644786a51967d3776b97d82f46029/init.lua#L396 for an example
19:22 paramat        use 'place schem on vmanip' between 'set data' and 'write to map', and create a table of positions between 'get data' and 'set data'
19:22 paramat        as Krock advised
19:24 swift110       hey all
19:28 paramat        Vanta in your 2nd code paste, you are not changing 'ivm' in the y loop
19:29 paramat        the loop is better in ZYX order, then you can just do ivm = ivm + 1 in the x loop
19:33 Vanta          Yes, I've noticed, I just copypasted this from somewhere
19:34 Vanta          It still wouldn't work though, because I'm testing if content_id is default:air
19:34 Vanta          While it should be just "air"
19:34 paramat        yes
19:35 paramat        anyway, in 'on generated' everything has been generated, including caves
19:35 Vanta          Well, I had "working" snippet before that did detect stone but didn't detect air, so I came to this false conclusion that caves are generated later
19:36 Vanta          And tried altering the code, searched for examples, came up with the snipped you've seen, but all this time I've been checking for wrong node id
19:38 Vanta          Why  I should just make another loop only for placing decorations? Perfomance reasons?
19:38 Vanta          should'nt*
19:38 Vanta          I mean schematics
19:40 paramat        because 'place on vmanip' adds a schem to 'vm', not 'data'. so in your paste when you did 'set data (to vm)' you were overwriting the schems you had added to 'vm'
19:40 Vanta          No, I mean completely separate loop that just does place_schematic_on_vmanip
19:40 Vanta          Without setting and writing to map vm data
19:45 Vanta          https://pastebin.com/QZ0jdCdU
19:45 Vanta          This for example
19:45 Vanta          It works for me
19:45 paramat        ah you mean using 'place schematic' instead?
19:45 Vanta          no, using place_schematic_on_vmanip
19:47 paramat        ok yes just saw the paste
19:48 paramat        i can't see how that paste works, you never write the vm to map after adding the schematics
19:49 Vanta          I don't know either, but it does exactly what I want, on first loop it adds floating bush leaves to air, on second loop it spawns trees on stone nodes
19:50 paramat        plus you have already looped through the mapchunk already, doing it twice may be pointless, might as well create a table of positions n the first loop
19:50 paramat        hm weird :)
19:51 Vanta          Well yes that's why I had doubts about that eariler
19:55 Vanta          https://imgur.com/a/eDnSeWY it's dark and trees are too dense (1/5 chance of spawn) but they are clearly spawned
20:03 Krock          don't pass "data" to write_to_map
20:03 Krock          and move write_to_map below the 2nd 3D-loop
20:03 Krock          that should solve the lighting issues IIRC
20:10 paramat        "don't pass "data" to write_to_map" yes, that's a common mistake started by a mistake in hmmmm's lvm example
20:11 paramat        even if it works it's still bad code ;)
20:12 Vanta          Well anyway now I have read voxel manipulator wiki page and seen methods
20:14 Gael-de-Sailly you should define your content_id once, at beginning
20:14 Gael-de-Sailly avoid using it in the loop, it takes time
20:14 Vanta          It's just a test example
20:31 paramat        the wiki page is probably out of date and misleading. i made a thread in the news forum with a good example
22:23 MineLord       Is there a way to have multiple admin accounts for a server?
22:28 ThomasMonroe   yes
22:28 ThomasMonroe   just grant them 'all' :P
22:32 MineLord       Thanks
