02:38 paramat        if you use valleys mapgen see https://forum.minetest.net/viewtopic.php?f=18&t=20501 for important info
05:41 air            are there any callbacks when a node is loaded or unloaded?
05:54 sofar          air: no
09:34 sur3           whats wrong with this line, it doesnt stop when nodename is equal to ignore?: while (nonename ~= "ignore") and (nodename ~= "air") and (pos.y<max_y) do
09:35 sfan5          you spelt nodename wrong
09:35 sfan5          also the brackets are not required
09:35 sur3           ohh thankx xDDD
09:35 sur3           yes i used the brackets because it didnt work xD
09:36 sur3           but was just the spelling mistake then xD
09:48 sur3           hmm this example 2 seems not to work as expected.. https://dev.minetest.net/minetest.get_node
09:56 entuland       sur3: how is it not working as expected?
09:57 sur3           well the function should have loaded an area and get a node.name ~= ignore then, but my code stopped inside an ignore, meaning the node returned was still not loaded
09:58 entuland       I suspected something like that... checking what read_from_map() should actually do
09:59 sur3           probably VoxelManip:get_node_at() is the better function..?
09:59 air            minetest.get_node_or_nil()?
10:00 entuland       get_node_or_nil() will still fail to return an unloaded node
10:00 entuland       sur3: I think you need both read_from_map() and VoxelManip:get_node_at()
10:01 air            you want to get an unloaded?
10:01 entuland       he's trying to make this example working: https://dev.minetest.net/minetest.get_node
10:02 entuland       sur3: dump out what you get from get_node_at(), it may be something different from what you get from get_node()
10:03 entuland       the api reads it will return a MapNode table, not sure if it's the same thing
10:03 sur3           the api says a table also containing name so should be fine
10:03 air            so that example doesn't need a force loader?
10:03 entuland       according to the api, the read_from_map() is necessary to force the loading of an unloaded area
10:04 entuland       otherwise even the manipulator will get "ignore" nodes
10:05 air            minetest.forceload_block() also loads an area
10:07 entuland       I have a feeling that will force that to stay loaded till forceload_free_block() gets run on the same pos or till the server gets restarted
10:07 air            https://github.com/auouymous/teleport_sd/blob/master/init.lua#L313
10:08 entuland       yep, even in that usage sample, seems like additional handling is necessary to avoid keeping stuff loaded: https://github.com/auouymous/teleport_sd/blob/master/init.lua#L334
10:09 air            would the example block until the area is loaded?
10:09 sur3           doesnt get_node_at() take a position parameter? o.O
10:09 air            nah, it returns a node at random pos :)
10:09 sur3           lol?
10:10 entuland       it does, sur3 https://github.com/minetest/minetest/blob/master/doc/lua_api.txt#L3010
10:10 sur3           ahh ok thx
10:10 sur3           because at other line in api it was only called get_node_at() ^^
10:10 entuland       just referencing the method probably :)
10:11 sur3           ok
10:16 sur3           still returns ignore: https://pastebin.com/tBPqFwwa
10:18 entuland       ouch
10:19 sur3           hm?
10:19 entuland       then I have no idea how to debug that further
10:19 sur3           oh
10:19 sur3           probably this forceload_block then?
10:19 entuland       not sure
10:20 air            the forceload works perfectly
10:21 entuland       there probably is some way to have the nodemanip working (after all, what you're experiencing there looks like a bug, sur3)
10:22 entuland       if you need to have it working no matter what use forceload as advised by air, just make sure you release those forceloads afterwards
10:22 sur3           well I'm using minetest 0.4.16
10:23 entuland       also try to forget about pastebin.com, it's crappy and often firewalled, there are way better services around
10:23 sur3           https://github.com/minetest/minetest/blob/master/doc/lua_api.txt#L4507 - I'll set that to false then
10:23 entuland       no that only applies to the server restart
10:23 sur3           ok
10:23 entuland       if you don't release it, the area will remain loaded even if you move away
10:24 sur3           but setting it to false is a good idea anyway isnt it?
10:24 entuland       indeed it is
10:24 sur3           to true i mean
10:24 entuland       yep it should be set to true
10:24 entuland       that thing has a weird default
10:24 sur3           yes thats also what i was wondering about ^^"
10:25 air            it defaults to true
10:26 air            nevermind
10:29 sur3           ok with the forceload it seems to work
10:30 ManElevation__ heyaii! one question, why do i sometimes get connection timeout on my own server when im connected to the same network but using a different device?
10:30 sur3           https://pastebin.com/880iwvRd
10:31 sur3           can i just do minetest.get_node(pos).name after the forceload or do i still need the voxel manip?
10:32 air            you shouldnt do anything after the forceload
10:32 air            you need a timer and keep checking the node
10:32 air            it takes time for it to load the area
10:32 sur3           what? o.O
10:33 sur3           oh
10:33 air            asynchronous
10:33 sur3           so the server will stuck for all players if I do it without a timer or just for the player that triggered the function?
10:34 entuland       ManElevation__: try to forget about pastebin.com, it's crappy and often firewalled, there are way better services around
10:35 entuland       gist.github.com or hastebin.com or many others
10:35 entuland       oops
10:35 entuland       sorry
10:35 air            if you forceload and immediately get_node_or_nil it will return nil
10:35 entuland       I mistaken sur3's link as yours, ManElevation__, my apologies
10:35 sur3           ok then I will keep the voxel manip
10:36 air            the voxel manip looks like it will block
10:36 sur3           will it block the whole server or just the user with whom the function is called?
10:36 air            that wouldn't be good on servers
10:36 air            that code runs on the server
10:37 sur3           yes but isnt the server multithreaded?
10:37 air            dunno
10:39 sur3           the function is called via minetest.after
10:41 sur3           think I'll just hope that the function is called in parallel to normal server actions so it doesnt block the players.. ^^
10:41 sfan5          sur3: nothing else can happen while lua code executes
10:42 ManElevation__ entuland np
10:42 sur3           sfan5, what really? o.O
10:42 sfan5          with the exception of loading data from disk and mapgen, the server is entirely single-threaded
10:43 sur3           so that's why minetest is always to stucky and slow.. no parallelization.. o.O
10:43 sur3           *so stucky
10:45 sur3           think I'll use the forceload combined with voxel_manip anyway, the stucking should seldom happen as more and more of the map is loaded.. ^^"
10:45 sfan5          you'll run out of ram at some point
10:47 sur3           oh so loading means the get node also returns ignore if the map already is created on hdd but not loaded in ram?
10:47 sur3           will 5.0 have more parallelization?
10:48 sfan5          get_node can only retriee nodes that are currently loaded in ram
10:48 sfan5          retrieve*
10:49 sur3           oh ok thought it would only return ignore if the map was not generated, but then I could have walked less to test the loading :D
17:35 quater         Hi, I would like the player to shoot a fire ball like in https://github.com/MT-Axinite/mobs_monster/blob/master/dungeon_master.lua . Is it the same way for the player ?
17:37 sfan5          have you tried?
17:37 quater         no
17:37 Krock          you'd need to spawn the arrow and set a velocity but then it surely will work
17:38 Krock          just put some effort in
17:38 sur3           I had a problem of some stuff breaking because someone used - meaning only a minus sign as his username, how can i prevent such usernames?
17:46 sfan5          modified version of the no_guests mod
17:49 quater         the player isn't a mobs and the arrow has a fixed velocity, I would like a variable one
17:52 Astrobe        Actually making players shoot missiles requires you to dig a little bit in Mob Redo's code.
17:53 Astrobe        if quater is still arround he/she's lucky cause I've done exactly that a few days ago, so I can share it.
17:54 sur3           sfan5, thx
17:55 Astrobe        It should be noted that the throwing mod can do that too, perhaps more easily, but it uses balistic trajectories which may not be what you want.
18:00 Andrey01       hi
18:06 Andrey01       can anybody help me with code problem? I can not call my function https://gist.github.com/Andrey2470T/44bf7cb5c01821fef9cf1f72bc286286
18:06 Astrobe        I have trouble with slabs. Small mobs have a tendency to enter in them and the other day I fell through one. Does it have something to do with the fact that it's a nodebox?
18:07 Krock          falling through slabs or entire nodes (on corners) is a common issue
18:07 Krock          s/common/known/
18:09 Astrobe        Andrey01, I think your thrid parameter should be a table but you forgot the { }.
18:11 Andrey01       third parameter is a table: time = {st_time = 0, expired_time = 0}
18:13 Astrobe        Ok, I misread it a little; but you cannot do that.
18:13 Andrey01       what can i not do?
18:13 Astrobe        Assignement is a statement in Lua IIRC, not an expression.
18:14 Astrobe        remove the "time =" I guess. Do the same for the other parameters.
18:18 quater         Astrobe, I would like to see it
18:19 Astrobe        https://pastebin.com/aaV8ATSA
18:20 Andrey01       thanks, Astrobe, now all works fine
18:20 Astrobe        Of course there's bit of my game's internal logic there that you don't need or have like the energy thing.
18:20 Astrobe        yw
18:27 Andrey01       here is strange error again, i need to add "end" to line 140, although there is already "end" on line 141 that closes "if"!
18:27 Andrey01       https://gist.github.com/Andrey2470T/1f276a7f812b240ca20a8bc0743d495f
18:27 Krock          "strange error" oh boi. there are no strange errors; just stilly mistakes
18:29 Astrobe        you don't need the "break" after "return".
18:29 Astrobe        What's strange, though, is that he should get a different error message for that. Lua detects when you put statements after a return IIRC.
18:30 Andrey01       ah, yes, exactly, 'return' keyword already finish the function
18:30 Astrobe        Like the previous case, the error message should have stated what I've stated - unless I'm wrong, that is.
18:33 Astrobe        Error messages are hard; it's like the MT error message about naming conventions that suggest to do the opposite of what you should do.
18:34 Astrobe        I guess it was written before the adoption of GitHub and it's habit of adding the "-master" suffix to folders.
18:34 Krock          > not using mod.conf in 2018
18:34 Krock          also, you cannot have any code in the same scope after a "return" in Lua
18:35 Krock          Lua cannot warn you about that unreachable code, so it throws an error on compile
18:35 Krock          s/compile/parse/
18:36 Astrobe        mod.conf ok, my ignorance.
18:42 Andrey01       btw, what to do in such cases when i want to call player:set_meta(key, value) and i want "value" to be other table? There are only set_int(), set_float() and set_string()
18:42 sfan5          serialize the table first

22:30 Alexand{er|ra} I'm trying to crate an inventory slot similar to the craft result slot on the main inventory menu, where when you take the item, you can take it again without putting the first one down, if another generates to take. Is it possible to do that, or does the client handle that slot specially in a way mods can't imitate?
22:31 TailSky        i can not join at sonos
22:31 Alexand{er|ra} What is sonos?
22:31 TailSky        How?
22:31 TailSky        server
22:31 rubenwardy     /        not   #
22:31 rubenwardy     also
22:31 TailSky        i am new
22:32 rubenwardy     not sure that that's even a channel
22:38 paramat        sur3 if a loaded area is not generated yet it will be full of loaded ignore nodes
23:07 Alexand{er|ra} Hmm. I think I got as close as I could get, but it doesn't work. I can store the results in the craftresult inventory location, but that's only triggered when the player tries to put the item *down*, not when they try to pick it up.
23:08 Alexand{er|ra} Actually ... If I turn it into a button instead of an inventory slot, this could work. It'll look funny to the player, but might function seamlessly.
23:16 Alexand{er|ra} Okay, that seems to work perfectly aside from the predicted strange appearance and the fact that .... Nope, the cosmetic issue is the only problem. The other issue was a typo in my code.
23:18 Alexand{er|ra} I guess the craft result slot in the crafting grid acts more like a button than an actual inventory slot. It seems like client-side special treatment, not server-side.
23:19 Alexand{er|ra} I'm perfectly happy with these results, but I wonder how much of the cosmetic issue I can cover up as well. That's a project for another time though.
23:20 Alexand{er|ra} Mostly, I needed to know if this could be pulled off before planning around having this as an option.
