00:41 MTDiscord     <09s​rinivas> Hi, is the json created by minetest really valid json?
00:42 MTDiscord     <09s​rinivas> I ask because python's jsson parser did not like it at all
00:49 MTDiscord     <08a​ppguru> @srinivas provide the JSON please
00:51 MTDiscord     <08a​ppguru> the json created by minetest should be valid, yes
00:52 MTDiscord     <09s​rinivas> its a large filee
00:52 MTDiscord     <09s​rinivas> moment
00:52 MTDiscord     <08a​ppguru> upload
00:53 MTDiscord     <09s​rinivas> https://cdn.discordapp.com/attachments/749727888659447960/794367691330551839/areas.dat
00:53 MTDiscord     <08a​ppguru> why .dat and not .json ?
00:54 MTDiscord     <08a​ppguru> You didn't use minetest.write_json, you used minetest.serialize
00:54 MTDiscord     <08a​ppguru> !next
00:55 MTDiscord     <09s​rinivas> oh
00:55 MTDiscord     <09s​rinivas> damn
00:55 MTDiscord     <09s​rinivas> ty
00:55 MTDiscord     <08a​ppguru> should be .lua then BTW
00:55 MTDiscord     <09s​rinivas> mhm
00:55 MTDiscord     <09s​rinivas> is there any way i can load it outside of minetest though>
00:55 MTDiscord     <08a​ppguru> yeah ofc
00:56 MTDiscord     <08a​ppguru> it's lua
00:59 MTDiscord     <09s​rinivas> ty
02:49 submariner    happy new year
06:48 ghoti         Happy new year, folks! I asked last week about how to configure a reduced frame rate in order to hopefully reduce CPU usage for MT on macos. I was told to search the settings for "fps" and/or "vsync". I see how fps works and that's great, but how would turning off vsync help? Anything else I can do?
08:09 vals_         happy new year everybody!
08:09 vals_         is paramat still gatekeeping improvements to MTG? 8-D
08:09 vals_         argh, nick tango_
08:09 vals_         ehm
10:26 Krock         ghoti: https://github.com/minetest/minetest/blob/master/minetest.conf.example#L726-L729
10:27 Krock         also https://github.com/minetest/minetest/blob/master/minetest.conf.example#L682-L685
10:27 Krock         those settings can be found in Main menu / Settings
11:23 tango_        hm is there a way in lua to tell how many parameters a function expects?
11:24 Krock         how is Lua supposed to know that?
11:24 Krock         you can pass as many you want, and as few you want
11:25 Krock         to capture all passed parameters, you can use {...} inside the function to put everything into a table which then can be used to get the length
11:27 tango_        Krock: lua knows how many params were declared in the function declaration
11:27 tango_        and the debug module exposes this information, but apparently not plain lua 8-/
11:28 Krock         ah right. I see what you mean
11:28 Krock         though debug.* functions should be available in the secure environment
11:31 tango_        too much effort in this case, I'll do it a different way
11:51 tango_        hm is there a way to combine textures by resizing and shifting them?
11:51 tango_        I want to place a small binoculars inside the mapper kit
11:51 tango_        but this doesn't work: 	inventory_image = "map_mapping_kit.png^[combine:16x16:4,4=binoculars_binoculars.png\^[resize:8x8",
11:52 tango_        (invalid escape sequence)
11:52 Krock         you need to escape like this:  \\^\\[
11:54 tango_        oh
11:54 tango_        duh the \ needs to be escaped itself
11:55 tango_        ok now at least it doesn't fail 8-)
11:55 tango_        buuut I can't see the overlay 8-/
11:55 Krock         well then, escape \\:  in resize
11:57 tango_        ooooh nice
11:57 tango_        Krock: thanks
11:57 Krock         !next
11:57 MinetestBot   Another satisfied customer. Next!
11:57 tango_        in fact, ^ and : but no [ are what need escaping 8-)
12:39 hecks         What's the best way to delete a list from an InvRef?
12:57 tango_        damn I need a good pixel art editor for linux
13:14 MTDiscord     <08a​ppguru> hecks: set_size(listname, 0) I'd say
13:15 Krock         tango_: gimp
13:15 tango_        Krock: meeeeh
13:16 Krock         wine mspaint.exe
13:16 tango_        lol
13:26 MTDiscord     <08a​ppguru> kolourpaint
13:31 tango_        wow I really suck at art anyway
13:31 tango_        appguru: lemme see
13:32 tango_        appguru: ah I think I tried that already
13:33 tango_        the bigget problem with all these programs is that they don't solve the fundamental issue that I can't draw for shit 8-P
14:16 deltanedas    could anyone take a look at https://github.com/minetest/minetest/issues/10765
14:49 tango_        hm I strongly suspect moreores needs to be updated following mtg's introduction of tin
15:23 dalz          the docs say there's no method to check an objectref's validity, but i'm pretty sure there's no other way to do what i'm after. i'm trying to reimplement psi (a minecraft mod to create spells through simple visual programming), and there a spell execution may be delayed, so that for example at the time of casting the object the player is looking at is stored and 10 seconds later moved a certain
15:23 dalz          distance
15:23 dalz          in that case i'd need to know if the object still exists
15:35 sfan5         yeah I don't see any other way there either
15:37 dalz          do i have to give up the ability to delay, or is there some secret trick i shouldn't know to test objectrefs anyway?
15:38 sfan5         "there is no method to text validity" means method in the API sense, there still is a way
15:38 sfan5         test*
15:39 sfan5         you could e.g. get_yaw() ~= nil as the yaw always exists when the object is in a valid state
15:40 dalz          cool, i'll use that then thanks
15:50 tango_        is there a way to temporarily override an attribute (color, brightness, etc) of a single node?
15:50 tango_        (not a node type)
15:52 sfan5         no
15:53 sfan5         best bet if you really really need to do this is an entity
15:56 tango_        sfan5: that won't do. the idea was to give the user a general idea of the direction in which something could be found
15:57 tango_        as in highlighting the nodes in that direction
15:57 tango_        hm
15:57 tango_        can entities occupy the same space as a solid node?
15:58 tango_        I really need to read up on entities
15:59 sfan5         yes
16:01 tango_        so I could have something like an arrow pointing to the proposed direction
16:02 MTDiscord     <08a​ppguru> yes sutre
16:02 MTDiscord     <08a​ppguru> sure*
16:02 tango_        and remove it in a timer and/or on server close
16:02 tango_        can entities glow?
16:03 tango_        (not illuminate the surroundings, just glow)
16:03 Krock         yes. use "glow" property
16:04 tango_        or maybe the particles mechanism would do
16:07 MinetestBot   02[git] 04kilbith -> 03minetest/minetest: Formspecs: Fix broken texture escaping with model[] 13ff921f6 https://git.io/JL7XO (152021-01-01T16:03:34Z)
16:10 sfan5         particles can glow too
16:12 tango_        and I think they're the most appropriate in this case
16:12 tango_        I'll try to work on that
17:08 search_social i know how to make a ramp but it just acts like a normal block when people stand on it; is there any way to make a ramp that will act like a slide that people slide down?
17:39 maxmonamour   Does anyone know of an example of billboarding being used by a mod in Minetest?
17:41 search_social what is "billboarding"
17:41 MTDiscord     <08a​ppguru> > Noun. billboarding (uncountable) (computer graphics) A technique in three-dimensional graphics in which a sprite is rendered perpendicular to the camera without respect to camera movement. Early first-person shooter games used billboarding for enemies rather than full character models. This is effectively what particles / sprite drawtype are.
17:42 search_social thanks
17:42 maxmonamour   Y
17:43 maxmonamour   Oops, yeah*. Basically a flat texture that always faces camera, with no 3d geometry. Specifically something that is supposed to be part of the world, not the UI
17:45 search_social but not the sky?
17:45 search_social the sun and moon in the sky do it
17:46 search_social and there's mods that change the sun and moon
17:46 search_social and the sky for that matter
17:46 MTDiscord     <08a​ppguru> search_social: no
17:47 MTDiscord     <08a​ppguru> well... sun and moon might actually be using billboarding, but they are exceptions
17:48 maxmonamour   yeah I kind of assumed that those examples might be operating in a different context or they might be modeled.
17:50 maxmonamour   either way i figured that it'd be more productive if i could find an example of nodes or entities being implemented with nothing beyond a billboarded graphic than try to figure out how to use that code, if it is in fact using billboarding

17:51 MTDiscord     <06F​lamore> Billboard sprites are cool
17:51 MTDiscord     <08a​ppguru> meh
17:51 MTDiscord     <08a​ppguru> the player actually defaults to a billboard sprite
17:51 MTDiscord     <06F​lamore> IK
17:51 MTDiscord     <06F​lamore> That green wizard looking thing
17:52 maxmonamour   wait, by default in minetest the player shows as a billboarded sprite? is that from the engine or Minetest game or???
17:52 sfan5         the engine
17:53 maxmonamour   Welp. I've never even seen that
17:53 MTDiscord     <06F​lamore> Because most games use the 3d model
17:55 maxmonamour   Hmm. I have seen this before. This isn't billboarded, though, this is a 2D texture applied to a plane, it appears
17:56 maxmonamour   (I guess "2D texture" is redundant)
17:56 MTDiscord     <08a​ppguru> ah yes, it is
17:56 sfan5         yea it's not billboard
17:57 MTDiscord     <08a​ppguru> it is drawtype = "upright_sprite"
17:57 MTDiscord     <08a​ppguru> billboarded would be drawtype = "sprite"
17:57 maxmonamour   ahhhhh! i'll take a look at that. thanks!
17:59 search_social appguru: do you know a way for me to change a .png file into a minetest build?
18:00 MTDiscord     <08a​ppguru> "change a .png file into a minetest build?" ?
18:00 MTDiscord     <08a​ppguru> you mean changing the base textures?
18:01 MTDiscord     <08a​ppguru> base textures are in <installation_directory>/textures/base/pack
18:02 search_social like if it's a 256x256 .png file it becomes a 256 block by 256 block build
18:02 maxmonamour   if you have a standalone texture you can basically just throw it in the game and use it. or if youre trying to replace a mods existing texture you can do the same
18:02 MTDiscord     <08a​ppguru> ahhhh
18:02 maxmonamour   oh
18:03 MTDiscord     <08a​ppguru> Well, I wrote a mod which can do that: https://content.minetest.net/packages/LMD/voxelizer/ It is quite an overcomplication though, so I'd recommend you to go with something like: https://forum.minetest.net/viewtopic.php?t=20411
18:33 search_social hmm i said /vox model world-map.png then /vox 1 and /vox 2 and it crashed
18:35 MTDiscord     <08a​ppguru> yeah because /vox model expects an obj model
18:35 MTDiscord     <08a​ppguru> you'd have to get a plane model, then do /vox model plane.obj and /vox texture world-map.png and finally /vox place or /vox 1 and /vox 2
18:57 search_social okay i made a blank model in blender and it's just a cube and i exported it as a .obj file but it has "vn" lines instead of "vt" lines
19:00 maxmonamour   what would be the most effective way to change all players collision sizes down to 1x1 node in a new game? i presume that the first person camera will be somewhere else
19:01 maxmonamour   right now i'm using a copy of devtest
19:49 MTDiscord     <08a​ppguru> here's plane.obj
19:49 MTDiscord     <08a​ppguru> https://cdn.discordapp.com/attachments/749727888659447960/794653484153962556/plane.obj

19:52 search_social thanks
19:59 search_social idk it makes a weird house shape
20:00 search_social and i can't seem to recognize the .png on it
20:01 search_social https://0x0.st/-rd9.png
20:01 search_social the /texture is https://0x0.st/iRxa.png
20:02 MTDiscord     <08a​ppguru> oof I messed it up
20:06 MTDiscord     <08a​ppguru> use this one search_social
20:06 MTDiscord     <08a​ppguru> https://cdn.discordapp.com/attachments/749727888659447960/794657912219762708/plane.obj

20:11 MTDiscord     <08a​ppguru> well, i get a similar thing - reason being the high resolution of the texture - voxelizer doesn't apply proper filtering
20:12 MTDiscord     <08a​ppguru> you should probably use imaging, it's more suitable for this specific thing: https://forum.minetest.net/viewtopic.php?t=20411
20:12 search_social if i say /vox place [scale] with the exact right argument to scale will it work?
20:14 search_social or if i convert the picture to a .bmp myself
20:14 MTDiscord     <08a​ppguru> if you scale it yourself to the scale you want it will work
20:14 MTDiscord     <08a​ppguru> but as said, I strongly advise you to use imaging for now
20:34 search_social thanks
20:34 search_social imaging worked
21:07 search_social https://0x0.st/-rnK.png
22:58 tango_        I'm not sure I understand the minvel/maxvel for particles
22:58 tango_        what's the unit of measurements?
22:58 tango_        blocks/seconds?
22:58 tango_        nodes/second?
23:21 MTDiscord     <10J​ordach> in blocks/nodes/meters
23:21 MTDiscord     <10J​ordach> all the same values
23:35 tango_        hm apparently the vel and acc is fixed at creation time
23:35 tango_        so one cannot do a particle with a “noisy” motion
