Time  Nick         Message
03:42 Mr_Pardison  greetings!
06:42 paramat      !tell IhrFussel do you know very roughly the MT version when your 'randomly stopping vehicles' issue started? did it happen in 0.4.16 stable?
06:42 MinetestBot  paramat: I'll pass that on when IhrFussel is around
09:32 MinetestBot  IhrFussel: Jul-20 06:42 UTC <paramat> do you know very roughly the MT version when your 'randomly stopping vehicles' issue started? did it happen in 0.4.16 stable?
09:34 IhrFussel    !tell paramat 99% sure it did not happen in 0.4.16 but in backport 0.4.17 from Dec ... and it didn't happen in 0.4.17.1 still so I think it is fixed there...did you test 0.4.17.1?
09:34 MinetestBot  IhrFussel: yeah, sure, whatever
10:18 IhrFussel    The stalling issue makes my server partly unplayable... I advise every server owners with an active playerbase to check the chat log and search for things like "laaaag" or "map not loading" or similar
10:20 tenplus1     hi folks :)
10:21 IhrFussel    The stalling does not ONLY affect mapblock sending
10:22 tenplus1     also affects inventory movement (from yesterday)
10:22 tenplus1     hi fussel
10:22 IhrFussel    Or well...it does technically I guess...mesecons won't work when it happens
10:25 IhrFussel    Ihave 10 videos for proof now that clearly show that only certain app users with random names cause this...the map loads again as soon as the problem user logs off
10:26 tenplus1     thing is... is it the area they are in causing issue, sauth or some player data being loaded/saved ??
10:26 IhrFussel    There is nothing busy server side
10:27 IhrFussel    Everything else works, the clients somehow BLOCK map sending/updating
10:27 tenplus1     so something about that particular client is stalling mapload ?
10:27 IhrFussel    One client is somehow able to ruin the game for everyone else
10:29 tenplus1     you could always set:  strict_protocol_version_checking = true
10:29 tenplus1     and force players to use 0.4.17 and above
10:31 rubenwardy   FFS, why are longs 64 bits in the kernel
10:31 rubenwardy   This is silly
10:31 tenplus1     hi ruben, also dunno what that is
10:31 tenplus1     *means
10:31 IhrFussel    First I need to make sure that it affects all MT servers and not just mine (which is very unlikely since the hardware of the server is pretty modern)
10:32 rubenwardy   Longs are usually 32bit, and is that size when in other code in Android
10:33 rubenwardy   This is why u64 is a good idea when the size matters
10:33 tenplus1     how does it affect things with longs 64bit
10:34 rubenwardy   It's used as flags to control a function. A bit like CSM flavour limits, instead of using tons of booleans you use a number and set individual bits
10:34 tenplus1     ohhh
10:34 tenplus1     gotcha
10:35 IhrFussel    tenplus1, do you save the chat log of users? In case you do could you please look for certain messages that could indicate that map loading issue?
10:36 tenplus1     no-one has ever complained about map issues on Xanadu, my inbox only contains books with coords for banned/limited players protected areas
10:36 tenplus1     but then again, we're still on 0.4.16
10:39 IhrFussel    It happened before 0.4.17.1 already ... but I meant the chat log of people chatting publicly
10:39 tenplus1     it's monitored, yes... but like I said no-one has ever mentioned issues with the map pausing/loading/glitching
10:43 IhrFussel    It is definitely *not* all app users... not all random names cause this, but quite a few
10:43 tenplus1     coudl the particular player that causes the issue be using csm mods to stress information between server and client ?
10:45 IhrFussel    Too many different people for that
10:45 IhrFussel    I'm pretty sure it is a broken app that handles mapblocks wrong
10:46 tenplus1     so many bogus clients that could do many weird things.. we need a way to stop them connecting
10:46 tenplus1     hi lumber
10:46 IhrFussel    But ONE client should never be able to stall the ENTIRE map
10:46 tenplus1     yeah, it's annoying
10:47 IhrFussel    So maybe the server waits for each client to acknowledge something and never gets a reply or something
10:47 tenplus1     true, we need a dev to ask for that one
10:48 IhrFussel    Or some kind of endless loop between server <-> client
10:48 IhrFussel    I could reduce block sends per client to see if that fixes/improves it
10:49 tenplus1     worth a try
10:49 IhrFussel    It was 20, after restart 10
10:50 IhrFussel    What's the value on xanadu?
10:50 tenplus1     checking
10:51 tenplus1     max_simultaneous_block_sends_per_client = 3
10:51 tenplus1     max_simultaneous_block_sends_server_total = 40
10:53 IhrFussel    I think the latter setting is ignored, not used anymore by the engine
10:54 tenplus1     :P
10:54 IhrFussel    Only 3? Map loads quick with that value?
10:54 tenplus1     surprisingly yes
10:54 tenplus1     I can use fast and run any direction and map loads quick enough to handle it
10:54 IhrFussel    I think setting it higher means less network packages
10:55 tenplus1     considering server is in US and I'm in UK
10:58 IcyDiamond   i wonder if its possible to make an npc "build" a schematic
10:58 IcyDiamond   aka place nodes in sequence
10:58 IcyDiamond   instead of just spawning the schematic
10:58 tenplus1     you could have a schematic saved as a table, loop through table from bottom to top and use npc/mob pathfinding to move to position and place node and keep going
10:59 IcyDiamond   i guess
10:59 IcyDiamond   i might try at some point
10:59 tenplus1     also hi :)))  hi raven
11:01 IcyDiamond   lol hi
11:01 IcyDiamond   :P
11:02 Raven262     Hi tenplus1
11:03 tenplus1     o/
11:05 IhrFussel    First symptom of the map stalling is map loading very slow suddenly
11:05 tenplus1     and it only happens when a specific player signs on ???
11:06 IcyDiamond   rubenwardy: https://i.lunasqu.ee/Screenshot_18-07-20-14:05:33.png is it just me or is the api doc unreadable now?
11:06 IhrFussel    And works again when that specific player leaves yep
11:06 tenplus1     and youv'e asked that user what client they use ???
11:06 IhrFussel    Well the map doesn't stall right away...it can take a moment
11:07 IhrFussel    I can try but most app users don't understand English
11:08 rubenwardy   IcyDiamond: any errors in the console?
11:08 tenplus1     o/ fixer
11:08 rubenwardy   What os/gtk theme?
11:09 Fixer        hi
11:09 IcyDiamond   rubenwardy: the links on the sidebar all 404 as well
11:09 rubenwardy   Must have broke some links then
11:09 rubenwardy   What's the URL?
11:09 IcyDiamond   https://rubenwardy.com/minetest_modding_book/lua_api.html
11:14 IhrFussel    tenplus1, any reason why minetest.item_eat(5) won't work in the beverage mod? I use stamina as hunger mod
11:14 IhrFussel    It just won't fill the bar when I drink something
11:15 rubenwardy   Code?
11:16 IcyDiamond   tenplus1: is pathfinding in the engine or your mobs mod?
11:16 IhrFussel    https://github.com/minetest-mods/beverage/blob/master/init.lua#L136
11:16 IhrFussel    In on_use()
11:17 IhrFussel    Wait...
11:18 IhrFussel    Why is it a node and not a craft item?
11:20 tenplus1     fussel, if you use minetest.item_eat(value) it shoudl work fine
11:20 IhrFussel    Didn't know you can (ab)use nodes as tools for drinking
11:20 Krock        hi tenplus1
11:21 tenplus1     IcyDiamond: minetest.find_path exists but in the actual mob api we have pathfinding as well to move mobs
11:22 Krock        sup?
11:22 IcyDiamond   ok, i think i'll use your mobs mod
11:22 tenplus1     fussel: I use nodes for wine mod: https://notabug.org/TenPlus1/wine/src/master/init.lua#L44 and wine is eaten/drank ok with stamina mod
11:22 IhrFussel    That is so weird, I hear the drinking sound (defined before minetest.item_eat()) but no stamina change
11:23 Krock        hi IhrFussel, IcyDiamond :)
11:23 IhrFussel    Hey Krock
11:24 IcyDiamond   hey Krock
11:24 tenplus1     icy, setting self.path to hold minetest.find_path coords starts them off, also make sure pathfinding = 1, is set in mob def
11:25 tenplus1     hi Krock
11:25 Krock        heh tenplus1. 5 minute delay this time :D
11:25 Krock        you must be totally busy
11:26 tenplus1     hehe sorry dude, was looking through chat.. paused scroll so I coudl catch up
11:27 tenplus1     o.O ouch, the code is kinda wonky in beverage mod
11:27 tenplus1     all spaced wrong in places
11:29 IhrFussel    It's a rather old mod but I need some drinks :P
11:29 tenplus1     heh
11:29 tenplus1     farming redo has some added, but yeah... need to add more drinks... how about wine mod ? :PPPPP
11:30 IhrFussel    my players want tea and other healthy stuff =P
11:30 tenplus1     nice
11:30 IhrFussel    I also have the sandwiches mod by Annalysa and that one works
11:31 IhrFussel    And the sandwiches also just use on_use = minetest.item_eat(5),
11:32 tenplus1     are you using thirty mod ?
11:32 IhrFussel    Nope
11:33 tenplus1     in init.lua, line 160, have it say:    return minetest.item_eat(5)     and see if that helps
11:35 tenplus1     same with line 201
11:36 tenplus1     return minetest.item_eat(5)
11:37 twoelk       wasn't there some problem with certain mobile clients granting a too far interact reach? maybe that triggers too much map load
11:38 IcyDiamond   rubenwardy: so.. what's up with the docs?
11:38 IcyDiamond   error on my side?
11:41 rubenwardy   It's using the static CSS of my main site, as the page is missing a relative URL root
11:41 tenplus1     hi aerozoic
11:41 aerozoic     wazup tenplus1!
11:42 tenplus1     tinkering...  always tinkering :PP you ?
11:43 rubenwardy   IcyDiamond: https://github.com/rubenwardy/minetest_modding_book/commit/b4057fda023d2c2189ef5333caa9c98aacba37a3
11:44 rubenwardy   IcyDiamond: seen the new chapters?
11:47 IcyDiamond   2018-07-20 14:46:45: ERROR[Main]: .../evert/minetest/bin/../mods/entitybuildqueue/example.lua:4: calling 'place_schematic_on_vmanip' on bad self (userdata expected, got table)
11:47 IcyDiamond   i wish it told me which arg
11:47 rubenwardy   You're probably giving it data rather than vm
11:48 IcyDiamond   VoxelManip() returns data and not a vm?
11:48 rubenwardy   Returns a vm
11:48 IcyDiamond   then whats the issue?
11:48 rubenwardy   You then get data with :get_data()
11:48 rubenwardy   Right
11:48 rubenwardy   Idk then
11:48 rubenwardy   Code? ;)
11:49 IcyDiamond   VoxelManip() returns nil
11:50 IcyDiamond   but the docs state that the position args are optional?
11:50 IcyDiamond   why does it return nil then
11:50 tenplus1     you could have npc change self.state to something unrecognised by api "building" for instance so the npc does nothing, then use do_custom to face direction and place node with punch animation and keep doing that until schem file built... then finally change self.state to "stand"
11:51 IcyDiamond   it returns nil even with arguments
11:51 IcyDiamond   im doing something wrong again
11:51 IcyDiamond   lmao
11:52 rubenwardy   When are you calling it?
11:52 IcyDiamond   that matters?
11:52 IcyDiamond   can't call it at load time?
11:52 IcyDiamond   so i guess i'll have to put it in an after()?
11:52 IcyDiamond   ¯\_(ツ)_/¯
11:53 IcyDiamond   nope still nil
11:53 IcyDiamond   well im confused
11:55 IcyDiamond   can i get an example of place_schematic_on_vmanip please
12:33 IcyDiamond   i dont understand why VoxelManip returns nil
12:34 tenplus1     make sure any coords are rounded , doesnt seem to work with things like 32.5 etc
12:34 IcyDiamond   https://i.lunasqu.ee/Screenshot_18-07-20-15:34:16.png
12:34 tenplus1     ahh
12:36 IcyDiamond   it doesnt say anywhere when or where it should be called
12:38 tenplus1     https://dev.minetest.net/minetest.place_schematic_on_vmanip
12:38 IcyDiamond   do i even need vm to get data out of a schematic?
12:38 tenplus1     yeh
12:38 tenplus1     check example link
12:38 IcyDiamond   I saw that already
12:39 Krock        how about write_to_map?
12:39 IcyDiamond   ?
12:40 IcyDiamond   i need the data from a schematic, not place it in the world
12:44 Krock        local placed = minetest.place_schematic_on_vmanip(...)
12:44 Krock        if that returns false, then you must specify the positions
12:44 IcyDiamond   minetest.get_voxel_manip() returns nil
12:45 Krock        err what
12:45 IcyDiamond   i have the same question
12:45 Krock        https://github.com/minetest/minetest/blob/master/src/script/lua_api/l_env.cpp#L963-L976 there's no way it can return nil
12:46 IcyDiamond   then what the f is happening here
12:47 Krock        here it works just fine https://github.com/SmallJoker/peoplecantlua/blob/master/peoplecantblur/init.lua#L127
12:48 IcyDiamond   i am super confused
12:50 xerox123_    Hello all o/
12:50 tenplus1     hi xerox
12:50 rubenwardy   IcyDiamond: at load time, there is no world
12:50 rubenwardy   The environment is loaded after mods load
12:51 rubenwardy   As you can't know all node definitions until loading is finished
12:51 tenplus1     use a minetest.after function to wait 3 seconds then place schem file
12:51 Krock        lol. you're calling this on load?
12:51 rubenwardy   Ah
12:52 rubenwardy   It'll be setting a nil table
12:52 rubenwardy   Nil meta tabld
12:52 rubenwardy   So it doesn't return nil, but instead an empty table
12:52 IcyDiamond   hmm what
12:52 IcyDiamond   ok i must be going crazy
12:52 IcyDiamond   it didnt work before with minetest.after either, now it does
12:52 IcyDiamond   well then
12:52 rubenwardy   L
12:52 rubenwardy   Ol
12:53 IcyDiamond   i have the confusions
12:56 IcyDiamond   static int ScriptApiBase::luaPanic(lua_State*): A fatal error occured: LUA PANIC: unprotected error in call to Lua API (not enough memory)
12:56 IcyDiamond   haha lol
12:57 rubenwardy   Oh dear
12:57 rubenwardy   That's... Not good
12:57 IcyDiamond   i tried to dump the data
12:57 IcyDiamond   that didn't go well
12:57 IcyDiamond   XD
12:57 rubenwardy   LVM exposes lots of weirdness like this when done wrong
12:57 rubenwardy   Oh wait lol
12:57 rubenwardy   Is that a puc version of an oom?
12:58 IcyDiamond   2018-07-20 15:56:11: ERROR[Main]: ServerError: AsyncErr: environment_Step: OOM error from mod 'entitybuildqueue' in callback environment_Step(): not enough memory
12:58 IcyDiamond   XD
12:59 IcyDiamond   how tf am i supposed to know how big of a vm i have to load
12:59 IcyDiamond   or create
12:59 IcyDiamond   place_schematic_on_vmanip requires me to specify positions
13:00 tenplus1     its one command i've never used
13:00 tenplus1     prefer normal schematic placement...
13:00 tenplus1     if anything I'd only use vmanip to load the area in question then place normal schem
13:01 IcyDiamond   its when you want to do the crazy shiz you run into problems
13:01 IcyDiamond   XD
13:01 rubenwardy   Store the schem size in a meta file
13:01 IcyDiamond   dammit
13:01 rubenwardy   Also, if you can work out how to emerge a schematic in an lvm with correct lighting
13:01 rubenwardy   Let me know
13:01 rubenwardy   Lol
13:01 IcyDiamond   lmao
13:02 rubenwardy   Or, alternatively find out how to read schem size from the MTS file
13:02 IcyDiamond   too much work
13:02 IcyDiamond   lol
13:02 rubenwardy   Lol
13:03 Krock        [LOL INTENSIFIES]
13:04 tenplus1     ::P
13:04 IcyDiamond   Motivation rate drops to 0%
13:04 Krock        Suicide rate rises to 100%
13:04 IcyDiamond   I don't feel like killing myself over a game
13:04 IcyDiamond   ¯\_(ツ)_/¯
13:08 tenplus1     is this just to place a schematic, or the start of the npc building thing
13:08 rubenwardy   CTF has separate confs for this
13:09 rubenwardy   ItB reimplements schematics using LVMs, and supports meta in the conf
13:19 IhrFussel    Can a core dev confirm that max block sends total is an obsolete setting?
13:29 sfan5        "obsolete"?
13:29 tenplus1     deprecated
13:33 sfan5        if it was obsolete it would not exist anymore
13:33 tenplus1     lol
13:33 sfan5        which is the case in 5.0, but not in 0.4.17
13:34 Fixer        https://twitter.com/without_pity/status/1019611100323680258
13:35 tenplus1     lol
13:38 IhrFussel    sfan5, could the removal of that setting cause such map stalling issues?
13:39 sfan5        you're not running 5.0 are you?
13:42 IhrFussel    No, but I removed the block sends total from my .conf because I was told that it#s not used anymore
13:43 sfan5        you should add that setting back
13:44 IcyDiamond   !title
13:44 MinetestBot  IcyDiamond: Without Pity op Twitter: "Its 33°C in Finland, inside the article circle.… "
13:45 IcyDiamond   lol same here and i live in estonia, which is just south of finland
14:04 Krock        IhrFussel: for reference, it's still in 0.4.x https://github.com/minetest/minetest/blob/stable-0.4/minetest.conf.example#L908
14:04 Krock        it's removed in 5.0-dev, which was already mentioned earlier
14:07 IhrFussel    Yes but if it's missing it sets the default (40) no? So it shouldn't be related to the map sending issues
14:08 Krock        40 is quite low for popular servers, but it does indeed take the default value if the setting is not specified
14:09 tenplus1     xanadu is set to 40
14:10 Krock        also the settings do not change in-game (exception is probably "/set"), so they surely can't be an issue here
14:15 IhrFussel    And no dev got an idea how a "bad client" could "block" map from sending to other clients? Is there a security hole? Does the client request too many blocks at once?
14:19 IhrFussel    It looks like the more "bad clients" play the sooner it stalls ... if only 1 is connected with such a client it still loads but very slow
14:20 Krock        to find out more, you'd have to add more stats to the minetest binary -> custom build
14:21 Krock        or analyse the network traffic (but the packets won't be easily readable)
14:24 rubenwardy   I had a similar issue
14:24 rubenwardy   Although I didn't notice anything about clients
14:25 rubenwardy   As CTF is perpetually full
14:25 rubenwardy   I did a wireshark
14:25 rubenwardy   Didn't really gain much though
15:27 orbitaldecay Greetings!

16:32 rubenwardy   I've been naughty and just merged PRs before
16:32 Krock        lol tenplus1. That's clearly too short
16:32 tenplus1     oops, 220 minutes then
16:32 Krock        rubenwardy: me too on bugfix PRs which have a good quality
16:32 tenplus1     falling.lua will need to be looked at soon enough and fixed
16:32 rubenwardy   I added screenshot.png to mesecons like this
16:33 Krock        very naughty indeed. lol
16:58 tenplus1     o/ benrob
16:59 benrob0329   o/ tenplus1
17:05 tenplus1     hi gary
17:06 garywhite    hi ten
17:07 tenplus1     you got any servers running benrob ?
17:09 benrob0329   No, I've thought about it a few times though
17:09 tenplus1     heh :)
17:09 tenplus1     am looking for some testers for a new falling.lua replacement
17:12 tenplus1     any takers ?
17:16 tenplus1     wb rdococ
17:17 Krock        ok, let's give it a try. < tenplus1
17:17 tenplus1     https://pastebin.com/XBpYT62E <-- make an empty mod with only "default" in depends.txt   ..  it'll override original entity for falling nodes with new functions
17:18 Krock        uhm.. "local builtin_shared = ..." I'm sceptical
17:19 tenplus1     heh, ignore that line
17:19 tenplus1     hi Gael-de-Sailly
17:19 Krock        "if below_node.name == "ignore" then" in combination with "get_node" might also delete them half-way falling
17:22 tenplus1     that does same as original falling.lua, just removes entities from unloaded areas
17:22 Krock        ehh
17:22 tenplus1     yeh, that was added
17:22 tenplus1     if falling node drops into unloaded map area it's removed
17:23 tenplus1     was meant for edges of map
17:23 tenplus1     dropping sand off the side kinda thing :D
17:24 Krock        that could be solved properly using get_node_or_nil
17:24 Krock        when it returns a valid "ignore" node then it's the world bottom
17:24 Krock        or world edge
17:25 tenplus1     the main difference with this is that falling nodes no longer replace smaller nodeboxes like before... that was a serious glitch... it checks first to make sure it's buildable_to or attached_node and can drop as item isntead of setting as node
17:30 sofar        rubenwardy: Krock: 30 days is the cutoff, but I often merge things 10-14 days old for repos that I know people are using and there's no sense in delaying patches getting merged
17:31 tenplus1     o/ sofar
17:32 sofar        heya
17:32 Krock        I see, thanks sofar
17:33 sofar        one of the reasons I don't like to define numbers for words like "reasonable" is that it'll make people just complain if you merge something 1 day too fast
17:38 Krock        on the other hand it's not sure whether weeks or months are maent
17:38 Krock        *meant
17:39 sofar        ah
17:41 Krock        tenplus1: node_fall_hurt doesn't seem to work (not defined in minetest.conf)
17:41 tenplus1     if you drop one of the falling nodes registered at top above you it should land and cause you damage
17:41 twoelk       reasonable time to respond may be longer during holiday seasons :-D
17:42 Krock        and same to the builtin falling node, six falling nodes suddenly become 4 by digging the buttom one
17:42 tenplus1     oh, that's due to the small timer I added to simulate lag
17:42 tenplus1     set delay to 0
17:42 tenplus1     line 34
17:44 Krock        oh I see. there's no falling_node_damage group
17:44 tenplus1     there is, yes...  the very top function just adds it to sands and tnt :)
17:45 * twoelk     is off to the weekend
17:45 Krock        ..and desert sand, which I use right now to test
17:45 tenplus1     but once the changes are complete I could make a pull and add the new group to .conf and api txt
17:45 * tenplus1   dropped sand on his head and died...  only had 1 heart :D
17:48 Krock        dropping it on my head. nothing happens
17:49 tenplus1     you using 0.5 ?
17:49 tenplus1     or 0.4.17 ?
17:49 Krock        no, 5.0-dev :P
17:49 tenplus1     ahh, I've not even tested for that yet
17:49 tenplus1     try dropping sand on mobs, works ok...  new player model might be iffy
17:50 Krock        yes, you'd have to check 1m further down
17:50 tenplus1     tried the get_node_or_nil instead of ignore and got a ton of "2018-07-20 18:50:14: WARNING[Main]: Map::removeNodeMetadata(): Block not found" errors
17:51 Krock        is that the client or server?
17:51 tenplus1     client
17:51 Krock        aha
17:51 tenplus1     ?
17:51 Krock        PR coming soon (TM)
17:52 tenplus1     local below_node = core.get_node_or_nil(below_pos) ; if not below_node then remove and return end
17:52 tenplus1     will go back to normal get_node and checking for "ignore" for now
17:53 Krock        not remove. return.
17:54 Krock        so that the entity can be saved into the mapblock
17:54 IhrFussel    tenplus1, stamina.eat() doesn't even get called with the drinks
17:55 IhrFussel    I added log messages to that function but it doesn't log anything
17:56 IhrFussel    If I return minetest.item_eat() the itemstack will not be returned right?
17:56 tenplus1     check this fussel, will make it work: https://pastebin.com/vUdig3Cn
17:58 tenplus1     Krock: but if sand dropped off edge of world wont that just have it constantly there and not be removed ?
17:58 Krock        no, it'll be loaded again
17:58 tenplus1     trying
17:58 Krock        and the on_step code sets the acceleration again
17:59 tenplus1     nope, once placed off the side of the world it stays there never to be removed... would rather it be deleted
18:14 IcyDiamond   tenplus1: do mobs have a unique id?
18:14 IcyDiamond   that i could access from self
18:14 tenplus1     only traders
18:14 tenplus1     but no, never needed a unique id for them before
18:15 IcyDiamond   ok
18:16 IcyDiamond   oh wait, self can have custom vars
18:16 tenplus1     yup, you can easily add your own
18:16 IcyDiamond   ok this makes it easier
18:16 tenplus1     e.g.   self.id = (math.random(1, 1000) * math.random(1, 10000)) .. self.name .. (math.random(1, 1000) ^ 2)
18:17 tenplus1     this is what traders use
18:17 IcyDiamond   yeah im going to use it for build queues too
18:18 tenplus1     remember that all self.* values are stored inside mob entity, so if it's in the middle of doing something (like building) it'll remember when it spawns in again
18:19 IcyDiamond   def
18:19 IcyDiamond   ?
18:19 tenplus1     huh ?
18:19 IcyDiamond   mob entity as any instance of it?
18:19 IcyDiamond   or what
18:20 tenplus1     yup, you can spawn 20 npc's and assign 1 to build or do something with do_custom and that one npc will remember and continue
18:20 IcyDiamond   ok
18:22 tenplus1     it does reset self.state to "stand" when they re-appear, but if you have self.path ready or self.build or whaverer you can check against it and set to "build" maybe to handle that
18:22 Fixer        CHAPA
18:59 IcyDiamond   tenplus1: how do i get the position of a mob
19:00 tenplus1     local pos = self.object:get_pos()
19:00 IcyDiamond   ok ty
19:02 IcyDiamond   tenplus1: so, can i make a mob walk to a specific position somehow too?
19:02 tenplus1     if mob has self.pathfind = 1 in it's definition you can set self.path = minetest.find_path() to guide it somewhere and it'll follow
19:03 IcyDiamond   oh okay, cool
19:03 tenplus1     sand monsters and npc have pathfind enabled by default :)
19:07 Krock        tenplus1: still trying to reproduce the client metadata warning
19:09 tenplus1     Krock: change line:158 to read: local below_node = core.get_node_or_nil(below_pos)
19:10 tenplus1     and line:158 to read: if not below_node then
19:10 tenplus1     and drop a sand block off the edge of the world... that produces the error
19:11 rubenwardy   Yessss
19:11 tenplus1     on 0.4.17-1 at least :)  dunno about your 0.5
19:11 rubenwardy   Soteria caught an apple cheatern
19:12 Krock        if not below_node then ... I assume "return end"?
19:14 tenplus1     does sand drop ok and land/set ok ? andif you drop on things like grass/flowers it replaces them ok ? and buildable_to items like torches drop ok ?
19:17 IcyDiamond   2018-07-20 22:16:21: ERROR[Main]: ServerError: AsyncErr: ServerThread::run Lua: Runtime error from mod 'npcbuildqueue' in callback luaentity_run_simple_callback(): Mod security: Blocked attempted read from house.meta
19:17 IcyDiamond   aw you cant read a file thats in the mod files?
19:17 Krock        tenplus1: dropped a node at -30910 to the bottom side of the world. no warning
19:18 tenplus1     weird, I get pages worth of errors when I do it on 0.4.17-1
19:18 Krock        IcyDiamond: it's because Minetest does not know that it's your mod
19:18 Krock        it would work on startup
19:18 IcyDiamond   dammit
19:19 rubenwardy   How does CTF do this?
19:19 IcyDiamond   so much for having a metadata file for a schematic...
19:19 rubenwardy   Is Settings exempt?
19:19 Krock        tenplus1: strange. could you please send me the exact file that you used to cause it?
19:19 IcyDiamond   now im completely screwed
19:19 rubenwardy   IcyDiamond: it works with Setting
19:19 IcyDiamond   it is a setting..
19:19 rubenwardy   The lua class for reading .conf   files
19:19 IcyDiamond   2018-07-20 22:17:56: ERROR[Main]:  [C]: in function 'Settings'
19:19 IcyDiamond   does it require the extension?
19:20 Krock        probably
19:20 IcyDiamond   nope, still errors
19:20 tenplus1     Krock: this is the code that causes the error: https://pastebin.com/U7w61T2m
19:21 Krock        and you're simply dropping sand towawrds the world edge?
19:21 rubenwardy   IcyDiamond: look at CTF in ctf_maps/schem_map
19:21 IcyDiamond   oh wait nvm
19:22 rubenwardy   It reads conf during run time
19:22 IcyDiamond   my mistake
19:22 IcyDiamond   i forgot to prepend the mod path
19:22 rubenwardy   It also has dynamic map reloading
19:22 tenplus1     yeah, built a little tower at the edge and drop sand off the edge... ton of errors
19:22 rubenwardy   So I can add maps without restarting
19:23 Krock        it replaces buildable_to nodes nicely, that's all I found out
19:24 Krock        no single warning/error
19:24 tenplus1     and if it drops on a thin nodebox the falling block will drop as an item isntead
19:24 tenplus1     that was the glitch that players would use to remove teleport pads/protectors etc
19:28 Krock        2018-07-20 21:28:21: WARNING[Server]: Undeclared global variable "np" accessed at /data/Minetest/run/bin/../mods/tenplus1_falling/init.lua:235
19:28 Krock        that's all I get
19:28 tenplus1     checking
19:29 tenplus1     oops, np shoudl be npos for sound... ehehe,, oops
19:34 tenplus1     could you try placing a very thin node like a carpet (something not replacable) and place tnt far above it, light and see if ti disappears ok
19:35 IcyDiamond   hm why does my find_path return nil
19:35 tenplus1     that means it cannot find path
19:35 IcyDiamond   its literally a straight line
19:35 IcyDiamond   minetest.find_path(pos, pos2, 16, 3, 3, "A*")
19:36 tenplus1     use "Dijkstra" instead f A*
19:36 IcyDiamond   tried it, still nil
19:36 tenplus1     so weird
19:36 IcyDiamond   indeed
19:37 tenplus1     and pos1 and pos2 are ok ?
19:37 IcyDiamond   yes
19:41 Sokomine     the pathfinder from burli is quite nice and gives good results
19:41 tenplus1     you got the link for that Sokomine
19:42 tenplus1     keep forgetting to check it out :D
19:42 Sokomine     https://forum.minetest.net/viewtopic.php?f=9&t=17406  i use it (at least one version) in my mob_world_interaction mod
19:43 Sokomine     probably not so intresting for your mobs, ten. they can't spend much time on calculating a good path and probably shouldn't learn how to open doors :-)
19:43 tenplus1     if mob pathfinding is set to 2 then they tend to break down walls and doors anyhoo :D
19:45 Sokomine     buuh! no breaking down of walls
19:45 Sokomine     rather let them build their own houses
19:45 tenplus1     would be nice tow atch them build
19:58 tenplus1     hrm, they dont seem to go through the doors when using pathfinder
19:59 IcyDiamond   tenplus1: what exatly is "per tick"
20:00 tenplus1     per tick, every 0.01 second
20:00 tenplus1     so 100 ticks per second
20:00 IcyDiamond   hm ok
20:00 tenplus1     if you do something with do_custom it runs per tick, if you want it to run every 1 second you need to add a timer to handle that
20:01 tenplus1     check out rat.lua in mobs animal for example
20:01 Sokomine     tenplus1: no, the pathfinder can just be modified so that it can find paths through doors. my mob_world_interaction mod is intended to help humanoid mobs who want to open doors and gates
20:02 tenplus1     ahh ok
20:03 tenplus1     cause mod kinda gave up with pathfinder, but redo api has it climbing on the roof to fall into a hole to get player
20:07 IcyDiamond   tenplus1: nothing is happening
20:07 IcyDiamond   or its taking a while cuz dtime is always like 0.03
20:09 tenplus1     show me code icy
20:09 IcyDiamond   oh wait
20:09 IcyDiamond   nvm
20:09 tenplus1     :P
20:10 Krock        sofar: do you remember whether this code worked reliable to test? https://github.com/minetest/minetest/issues/5246#issue-208040774
20:22 Krock        wrote a mod to update the node each second with a new rotation (set_node) and yet no warnings
20:26 IcyDiamond   can i make entity look at a position
20:26 IcyDiamond   or rotate towards
20:27 Krock        yes.
20:28 Krock        local dir = vecor.direction(pos1, pos2)  entity.object:set_yaw(math.atan2(-dir.x, dir.z))
20:29 Krock        if it's the wrong rotation, add another 90° or change the atan2 function accordingly
20:29 tenplus1     if you mean a mob then use mobs:yaw(self, yaw0
20:30 tenplus1     if you mean a mob then use mobs:yaw(self, yaw(
20:30 tenplus1     then it'll smooth rotate to look that direction
20:31 tenplus1     nite folks :)
20:32 MinetestBot  paramat: Jul-20 09:34 UTC <IhrFussel> 99% sure it did not happen in 0.4.16 but in backport 0.4.17 from Dec ... and it didn't happen in 0.4.17.1 still so I think it is fixed there...did you test 0.4.17.1?
21:04 sofar        Krock: never found a reliable reproducer, so no
21:05 Krock        too bad. :/

22:04 Krock        IcyDiamond: could it be that your Minetest binary needs updating? I see those lighting issues on the ground
22:05 IcyDiamond   Probably
22:06 IcyDiamond   I updated today though
22:08 Krock        oh, that's recent enough
22:09 Krock        whereas the npc movement is nice, they seem to place nodes outside the usual range
22:15 paramat      i guess they're simply pathfinding towards the currently placed node
22:16 IcyDiamond   The movement is quite crap, I'll have to experiment with it further
22:26 paramat      it's not so bad :)
