00:05 paramat      LuaJIT causes other problems though, especially with lua mapgens
00:07 pgimeno      which other problems?
00:08 paramat      limited lua memory, like 1GB
00:08 paramat      causes 'out of memory' crashes for many users
00:08 pgimeno      well, ffi is a sort of solution to that (if a LuaJit-specific version is implemented when LuaJIT is found)
00:09 pgimeno      it would be nice to have minetest.ffi :)
00:11 pgimeno      local ffi = minetest.ffi ; if ffi then --[[ffi-specific version]] else --[[plain lua version]] end
00:13 paramat      see https://github.com/minetest/minetest/issues/5442
00:14 pgimeno      I see
00:16 pgimeno      hm, that issue talks only about calling external C functions, but it misses the benefits of using it for low-level access to data and memory allocation
00:20 pgimeno      I mean, MarkuBu focuses on that but nerzhul seems to miss it
00:30 paramat      feel free to add to the issue
00:31 paramat      it might be reopened if there is some discussion
00:31 pgimeno      thanks, I think I will
01:09 pgimeno      ok, I got the mapgen proof of concept working! thanks a lot paramat
08:35 VanessaE     in regards to my channel being +s, it was in response to a non-MT troll that followed me from #frednode.
08:35 VanessaE     er #freenode
10:45 Taose        frednode XD
11:32 VanessaE     heh
12:17 ensonic      morning, is it possible to change the tiles on a block in on_place? or alternatively if I just register the variants, can I hide them from the inventory
12:17 sfan5        you can hide nodes from the creative inv if you mean that
12:18 sfan5        still no idea what you mean by "titles"
12:20 ensonic      tiles not titles
12:20 ensonic      I'd like to make a column mod, where the player places the sma eblock, but depending on what is above and below the blocks ajust their look
12:21 pgimeno      you can use group not_in_creative_inventory = 1
12:21 ensonic      thanks
12:23 Krock        there's the "color", "colorwallmounted" and "colorfacedir" drawtype
12:23 VanessaE     ensonic: ^^ that and each "look" needs its own node that your code will place as needed.  those are the ones you exclude from creative\ inv
12:24 Krock        in combination with palettes you don't have to create a huge amount of nodes
12:24 VanessaE     Krock: didn't we also get "colorsimplefacedir"?
12:25 VanessaE     (2 bit NSWE facedir, 6 bit color)
12:25 sfan5        i think so yes
12:25 Krock        0 occurrences of "colorsimplefacedir" in lua_api.txt
12:26 VanessaE     hm, guess not
12:26 VanessaE     I proposed it a while back.  coulda sworn some someone coded it.
12:26 VanessaE     (or it's named differently)
12:26 Krock        well, using colorfacedir you can manually change it to simplefacedir
12:27 ensonic      how do the color* drawtypes help?
12:33 VanessaE     if all you wanted for "adjust their look" is to change color, you could alter the node's color in-map.
12:33 VanessaE     but I assume "look" includes shape and overall texture.
12:35 ensonic      VanessaE, only change textures
12:35 VanessaE     yeah, then you do it the "usual" way and hide the extra nodes from the creative inv.
12:37 ensonic      VanessaE, thanks!
12:37 VanessaE     ^^ that by the way woulda been a good use-case for my "palettized texture list" idea (too bad no one wants to implement it)
12:39 ensonic      VanessaE, I converted the MC Conquest texture pack and there are a lot of such blocks (references in https://github.com/minetest/minetest/issues/2748)
12:42 VanessaE     I have zero experience with MC so I have little context.
12:43 ensonic      VanessaE, this is a video if the TP in action https://www.youtube.com/watch?v=yiAZ_mHrLiA
12:44 VanessaE     nice.   reminds me HavenNG
12:45 VanessaE     go take a look at MInetest HDX sometime
12:47 VanessaE     (at some point I need to implement that wide tiling feature the engine supports)
13:24 ensonic      coulumn stacking works \o/
14:38 ensonic      the columns: http://picpaste.de/screenshot_20171223_153647-KCZXknPs.png
14:45 sfan5        nice
15:12 ensonic      will clean it up and check for which material it makes sense
15:39 Beginner     Hello, is it possible to disable dropping items? if so, how? thanks
15:41 jas_         i believe there are a few ways, and one might be to override the minetest.item_drop function to not do anything.
15:42 jas_         another could be to minetest.override everything in minetest.registered_items making drop=""
15:42 GNU[BDC]     Hi, was there recent fix for default trees decay issue?
15:42 jas_         maybe there are other ways?
15:42 jas_         i dunno gnu[bdc], but did you try using the sneak key?  (how was it broken?)
15:43 GNU[BDC]     leaves do not decay when you remove trunk
15:43 Genshin      usually drop="" is the easy way out.
15:43 jas_         oh, i see.  it worked for me last i checked on 0.5.0-dev
15:44 Beginner     jas_ , Genshin: thank you!
15:44 Genshin      np
15:44 jas_         if you want to disable all item dropping from player (by hitting Q or dragging item out of formspec), then overriding minetest.item_drop should work.  and then perhaps adjust the behavior too, to depends for example on a privilege
15:45 jas_         but yes, drop="" is easiest, but you have to override everything and make sure this mod is last?  i think.
15:45 jas_         but actually i think you typically need to do this in a minetest.after anyway...
15:45 Genshin      Indeed.
15:46 Genshin      overriding minetest.item_drop is the best solution tbh.
15:50 Beginner     yay, it works: function minetest.item_drop(itemstack, dropper, pos) return itemstack end
16:04 jas_         i just realized drop="" if when you dig a node, and not when you drop one from inventory heh
16:05 jas_         so i think it's just that one way only.
16:15 twahm        Hello, I'm using player.getpos() that should return the player's position but I get this error: bad argument #1 to 'getpos' (userdata expected, got no value), someone knows why this happens?, according to the wiki I do not have to give any parameter
16:17 sfan5        player:getpos()
16:18 twahm        thank you
16:26 Krock        * player:get_pos()
16:26 Krock        the other one is the old name, kinda deprecated
16:26 Krock        or alternatively player.get_pos(player) but it's obvious that writing more than necessary isn't desired :)
17:21 pgimeno      is there a way to get the world seed?
17:21 Krock        F5
17:21 pgimeno      sorry, from Lua
17:21 Krock        server-side?
17:22 pgimeno      yes
17:22 Krock        minetest.get_mapgen_params()
17:23 Krock        https://github.com/minetest/minetest/blob/master/doc/lua_api.txt#L2815
17:23 Krock        nvm, that seems to be deprecated, so use minetest.get_mapgen_setting
17:24 pgimeno      would use name = "seed"?
17:24 pgimeno      if I'm understanding correctly, that would be it
17:27 pgimeno      ok, minetest.get_mapgen_setting("seed") works, with the caveat that it returns a string, thank you very much
17:35 Beginner     how do i set new inventory every time player tries to open inventory? because i need to update label in item_image_button[...,label]
17:42 Krock        Beginner, that's not possible right now
17:43 Beginner     YAY hehe
17:43 Krock        you'll have to update the inventory in another case
17:51 Beginner     and is it possible to call function when player open inventory?
17:52 Beginner     oops, nvm
19:05 paramat      GNU[BDC] the leafdecay issue is rare and we can't see how it is happening, so no fix yet
19:24 GNU[BDC]     paramat:  i recent update snow mod, leafdecay was fixed in snow mod leaves. Broken on default. Could it be connected?
19:26 paramat      yes it could, the mod may need fixing
19:28 paramat      the bug is likely in the mod
19:39 Beginner     in which cases can player:get_inventory() return value nil? local inv = player:get_inventory() -- everything ok, and then inv:get_stack(...) throw this:  attempt to index local 'inv' (a nil value)
19:48 pgimeno      are you sure that's the problem and not e.g. a scope problem?
19:51 Beginner     it is called in mt.after() , player is disconnected before executing code in mt.after, so player:get_inventory() should return nil, but nope.  inv:get_stack returns nil. Thats weird.
19:51 Krock        that can happen if you keep the player reference saved somewhere and someone leaves
19:52 sfan5        player references should not leave the scope they are created for (e.g. a callback)
19:52 Krock        get_stack never returns nil. it always creates a new stack if it wasn't found
19:52 Beginner     ok, so thats it. Hm but why not return nil at get_inventory line....
19:55 Beginner     fixed, thank you
19:56 Krock        !next
19:56 MinetestBot  Another satisfied customer. Next!
21:48 pgimeno      finished! https://gist.github.com/pgimeno/3f86ca27d2ad7d2bba4633448db059fb - thanks to all who helped
21:52 pgimeno      added screenshot
22:06 twahm        Because when I create a server, the minimap is always disabled?
22:15 paramat      a maze of nightmares
22:16 Beginner     pgimeno: that is cruel
22:19 pgimeno      well, you just have to find the way to the castle beyond the goblin city ;)
22:20 pgimeno      it's not so much about solving it as it is about watching it
22:20 paramat      twahm you're adding a maze to a core mapgen? which one?
22:21 pgimeno      I think twahm meant "why" instead of "because"
22:22 twahm        My mod only inserts mazes on the map, no matter what mapgen.
22:22 paramat      ok
22:23 paramat      every mapgen provides a 'mapgen object heightmap' that is an array of y values for every column in a mapchunk. the heightmap is available for use inside the 'on generated' function only
22:24 twahm        How do I access it?
22:24 paramat      https://github.com/minetest/minetest/blob/master/doc/lua_api.txt#L4191
22:25 paramat      maybe do a search on github for 'minetest mapgen oject heightmap' to see examples of use
22:25 paramat      i haven't used it myself
22:26 twahm        Thanks, and another question, is it possible to make the mapgen not affect the maze after generating it?
22:27 paramat      everything done in 'on generated' is after all mapgen, however
22:28 paramat      some core mapgen features extend over mapchunk borders into neighbouring already generated mapchunks, for example large caves. one thing that helps is to make sure all your nodes have 'is_ground_content = false' that stops caves eating the node
22:28 paramat      any specific problems?
22:28 pgimeno      I'm confused. Was there a question I'm missing?
22:30 twahm        I want the maze to be generated with blocks by default, but not to be altered, is it possible?
22:30 paramat      pgimeno twahm PM'd me
22:30 pgimeno      ah
22:31 twahm        pgimeno I am trying to generate a maze but I can not place it on the surface of the world
22:31 paramat      what you add in 'on generated' will not be affected because that's after core mapgen has finished in that mapchunk
22:31 Beginner     this: full_punch_interval = 5.0, means delay between on_use calls? its not working for me
22:32 paramat      twahm best host your code somewhere so people can look
22:35 pgimeno      heh, talk about timing :)
22:35 twahm        https://github.com/twahm/mazes
22:36 twahm        It is still very rudimentary
22:36 twahm        Use the PRISM algorithm to generate the mazes
22:37 pgimeno      I guess you mean Prim's (actually Jarnik's)
22:38 twahm        yes
22:39 twahm        Only that randomized
22:39 pgimeno      mm I see, that one has an ugly bias towards a point
22:41 twahm        First I had used depth-first search, but the mazes were very simple.
22:45 pgimeno      https://bl.ocks.org/mbostock/11167589 - it's biased towards the origin point
22:45 Calinou      <twahm> Use the PRISM algorithm to generate the mazes
22:45 Calinou      sounds like a maze that would spy on its visitors :P
22:46 twahm        What do you mean?
22:46 ThomasMonroe Calinou you up for some games of chess?
22:46 sfan5        there happens to be a NSA compaign by the same name, twahm
22:49 Calinou      ThomasMonroe: sure :)
22:49 Calinou      what time control?
22:50 ThomasMonroe 3+5?
22:51 Calinou      ok
23:01 twahm        How can I make things in the inventory not be lost when a player dies?
23:01 rubenwardy   disable the bones mod
23:01 rubenwardy   by deleting the folder
23:01 rubenwardy   or there's a setting
23:02 twahm        How do I disable the bones?
23:06 Calinou      rubenwardy: can you disable a built-in subgame mod?
23:06 Calinou      I don't think so
23:06 Calinou      isn't there a minetest.conf setting?
23:06 rubenwardy   I gave the two options
23:07 Calinou      https://github.com/minetest/minetest_game/blob/master/mods/bones/init.lua
23:07 Calinou      https://github.com/minetest/minetest_game/blob/master/mods/bones/init.lua#L171-L173
23:07 Calinou      d o c u m e n t a t i o n
23:07 Calinou      twahm: "bones_mode = keep" in minetest.conf should work, try that
23:07 Calinou      or "bones_mode = drop" to drop items without creating a bones node
23:08 paramat      those colour maze floods are nice
23:09 pgimeno      yeah they are
23:10 twahm        It's what I'm using to test, then it makes the materials change according to the biome
23:12 ThomasMonroe I'm back Calinou
23:12 Calinou      welcome back :)
23:12 Calinou      send me a challenge again if you wish to play
23:14 ThomasMonroe ok
23:14 Calinou      wait a few minutes
23:14 Calinou      (busy right nowx)
23:14 Calinou      -x
23:14 ThomasMonroe kk
23:19 Calinou      ThomasMonroe: ok, I'm here
23:57 Beginner     can anyone explain me full_punch_interval = 5.0 ? animation looks slower, but i can fast punch other players, i see no difference between value 5 and 1.
