05:21 frostsnow What does it mean when an item being defined with register_node() has a name prefixed with a ':'?
05:29 Brackston can you be more specific? do you mean like default:stone?
05:32 Brackston like minetest.register_node("bones:bones" ...?
05:33 Brackston frostsnow: Are you still around?
05:33 frostsnow Brackston: More like 'minetest.register_node(":bones:bones")'
05:34 VanessaE it means that node is being redefined by a mod that is not the original source of the node (e.g. a mod NOT named "bones" in this case)
05:35 VanessaE the leading : overrides the normal mod name check
05:35 Brackston Thank you VanessaE
05:35 frostsnow Ahhh, that would explain why it was in the farming mod.  Thanks VanessaE.
05:35 VanessaE yw
05:36 Brackston Would that create a conflict with the original mod?
05:36 VanessaE not usually, but if there were two mods redefining the same node, then there could be a conflict
05:36 VanessaE (whichever runs last takes precedence)
05:38 Brackston Good to know. Thank you for imparting your knowledge to us mere mortals.
05:39 Brackston The working of MT becomes clearer when folks like you share knowledge like that.
05:39 Brackston Thanks again

12:40 w_laenger Is the map incompatible since 0.5?
12:40 Krock no
12:41 w_laenger What's causing the error?
12:41 sfan5 there have been some map format changes a few months ago, that might be the problem

14:50 FatalNIX joined #minetest
14:50 FatalNIX ooooook
14:50 FatalNIX How is everyone?
14:51 FatalNIX I've decided to return to Minetest :D
14:51 FatalNIX I hear it's much cooler now. but I need to install extra stuff to make it worthwhile. what's a good bundle of things to get started with?
14:52 deltasquared FatalNIX: eh, there's no one "good set", it's way too large a search space. YMMV but I personally just played on servers and noted things I wanted to have for my own worlds
14:53 FatalNIX ic
14:53 Krock ooooook hello
14:53 deltasquared fwiw my set is things like technic, moreores, mesecons, digilines, pipeworks, things that add items of technical and useful nature
14:53 Krock xdecor adds many nice, helpful things. Don't forget that one
14:53 Taoki joined #minetest
14:53 deltasquared oh, and plantlife_modpack for variety in the world exploration
14:54 deltasquared !mod xdecor
14:54 MinetestBot deltasquared: X-Decor [xdecor] by jp - https://forum.minetest.net/viewtopic.php?t=12534
14:54 Krock just do ls in your mod directory and pastebin it :P
14:54 FatalNIX huh
14:54 deltasquared Krock: cannae do that, I have WIP mods of my own
14:54 FatalNIX is technic like, MC technic pack from ages ago?
14:54 deltasquared FatalNIX: ... kiiiinda, except without the hodge-podge mixture of different energy systems
14:54 Krock dunno. it has machines that are powered with HV/MV and LV generators
14:55 FatalNIX I see
14:55 bas080 joined #minetest
14:55 deltasquared FatalNIX: I haven't played the MC technic pack in *ages*, what sort of stuff would you be looking for in that
14:55 FatalNIX no idea heh
14:55 FatalNIX I like the whole lua modding thing about minetest
14:56 FatalNIX curious how powerful it is these days
14:56 deltasquared oh, as someone brought up on the intricacies of C/C++, lua has been a breath of fresh air and a joy to work with
14:56 FatalNIX C is dangerous and C++ I don't even want to start with.. heh
14:56 Krock well, it's fast with Lua, and faster with LuaJIT. much more hasn't changed there. Only the API functions increased a bit
14:56 deltasquared lua itself is fairly simple, it's just having something ready to hand (namely the minetest API) to do something useful with that's the fun part
14:57 FatalNIX tbh I find Lua without jit "fast enough"
14:57 deltasquared FatalNIX: you evidently have never used a lua-based mapgen then :P
14:57 FatalNIX ahahaha
14:57 FatalNIX yes but that involves mathematics
14:57 Krock FatalNIX, tell again when using a Lua mapgen or biome_lib
14:57 deltasquared or worldedit. let's just say it helps (profanity for emphasis redacted)
14:58 deltasquared pretty sure luaJIT is the default in any case
14:58 deltasquared for MT anyway
14:58 FatalNIX hm. are there any mods I should know about that implement MCs redstone behavior?
14:59 Krock what does redstone do? Is that something like mesecons?
14:59 deltasquared FatalNIX: mesecons
14:59 FatalNIX I always found redstone pretty cool
14:59 deltasquared Krock: kinda
14:59 deltasquared FatalNIX: mesecons is naturally yellow but otherwise it's the same kinda principle
14:59 FatalNIX Heh
14:59 FatalNIX I could care less about color :D
15:00 deltasquared FatalNIX: oh and also on needing a JIT, try running something like this https://github.com/thetaepsilon-gamedev/​libmt_node_network/blob/master/bfmap.lua and tell me you don't want more performance
15:00 FatalNIX I bought Minecraft like.. 10 years ago almost in order to build redstone CPUs
15:00 FatalNIX I'm weird like that
15:00 bas080 joined #minetest
15:00 deltasquared nothing weird about it, who doesn't want to feel like they can control things at the transistor level
15:00 deltasquared ... ok, maybe I just nerded out a bit
15:01 deltasquared FatalNIX: actually yeah I think we are both weird :P
15:01 deltasquared but SCIENCE!
15:02 FatalNIX I was able to test a lot of CPU arch design ideas I had and when mods came out to make gates easily compact I got even happier :D
15:02 FatalNIX and they were useful
15:03 deltasquared mesecons has gates already ;)
15:03 FatalNIX oh cool
15:03 FatalNIX I've actually been designing a new arch latthately.. I should test
15:03 FatalNIX I should test that
15:04 deltasquared among most the other things you'd expect from minecraft, such as pistons.
15:04 FatalNIX it has only 3 instructions XD
15:04 deltasquared FatalNIX: is it one of those weird arches that is still turing complete despite only having like five instructions
15:05 Krock but ruing machines are great!
15:05 Krock *turing
15:05 FatalNIX pop stack into memory, load stack with memory, and immediate onto stack
15:05 FatalNIX it's all you need
15:05 deltasquared oh, it's a stack machine, that's cool I guess
15:06 FatalNIX well here was my reason
15:06 FatalNIX I actually designed the first model of it for my MC world a while back
15:06 FatalNIX I wanted a machine I could just toggle switches on like a PDP-11
15:06 FatalNIX and set params for different parts of my base
15:06 deltasquared Krock: I searched "minetest mesecons turing machine" on youtube and didn't find anything, though MC redstone there's loads of versions of
15:07 FatalNIX but I realized that using memory mapped IO on this 12 bit 4K address system I can add branching controllers, interrupts, etc
15:07 FatalNIX it's like the exoskeleton of computing
15:07 FatalNIX not really..
15:09 Krock you could use FPGAs and Lua controllers to reduce the circuit size - but I'm not sure if that's what you want
15:09 FatalNIX so there's FPGAs in mesecons?
15:09 Krock https://github.com/minetest-​mods/mesecons/commit/07d074
15:10 FatalNIX interesting...
15:10 deltasquared FatalNIX: kinda. they just allow you to specify arbitary logic operations on gate inputs
15:11 FatalNIX wait a minute, this isn't the security scare mod I heard about is it
15:11 FatalNIX that lets people enter in Lua code
15:11 deltasquared FatalNIX: that's probably luacontrollers
15:11 deltasquared it is securable, I've seen the code to do it
15:11 FatalNIX I see
15:12 deltasquared the gist of it is a) restricting what the code can "see" in it's environment (no access to minetest.set_node() etc.) and b) registering a debug hook which causes a "timeout" when the interpreter exceeds a certain number of operations
15:12 deltasquared the latter does work in luaJIT by nature of turning the JIT off before running the restricted code.
15:12 troller joined #minetest
15:13 deltasquared I'm probably nowhere near an expert on these issues but it would be pretty hard to break the sandbox
15:13 FatalNIX heh.
15:13 FatalNIX I suppose with setfenv..
15:13 FatalNIX if it's 5.1
15:14 deltasquared there's limits on number of times it can execute for instance, and the size of it's "mem" table which is saved between runs - break them and the luacontroller in-game drops itself (though you can turn this restriction off per-world)
15:23 FatalNIX neat
15:25 deltasquared FatalNIX: oh, another one to add to the list I suggested earlier is pipeworks - in particular, the pneumatic tubes for item transport/routing, and things like a node breaker.
15:25 RedSoxFan08 joined #minetest
15:26 FatalNIX neat
15:26 deltasquared so I guess in a way those item tubes are another element in a "minecraft technic-like" set of mods
15:26 FatalNIX can I program the tubes?
15:26 deltasquared FatalNIX: "program"? there is a sorting tube though
15:27 deltasquared I'm not aware of a tube that lets you throw lua code into it. there is a digilines-controllable "filter injector" which allows for programmatic retrieval of items though - and the digilines messages could be issued from a luacontroller
15:29 RedSoxFan08 deltasquared: I don't entirely understand that, but it sounds cool.
15:30 Krock or use sticky pistons to move tubes away :3
15:30 RedSoxFan08 Krock: Okay, cool.
15:33 FatalNIX deltasquared: yeah that' what I meant, being able to control the tube flow, I could care less about the lua part

16:00 deltasquared you know that cliche when the end of a broom falls off... just happened to me
16:03 lumberJ Has anyone else had any issues with server crashes when using basic_machines with areas mod?

16:04 The_Loko joined #minetest
16:08 rtjure joined #minetest
16:08 deltasquared lumberJ: huh, interesting, -nan only usually happens if you do something daft like divide by zero somewhere
16:09 deltasquared I say "you" but I meant the mod dev
16:09 Taose Only pro coders can divide by zero and get away with it
16:09 deltasquared I can divide by zero whenever I want! *hic*
16:10 deltasquared lumberJ: how exactly did you trigger this
16:10 deltasquared standard bug reporting rules: steps to reproduce, what should have happened etc.
16:17 lumberJ thats the issue deltasquared, i am having difficulty reproducing it
16:17 lumberJ it seems to be related to activating a mover in a protected area, as reported by players
16:18 lumberJ but i myself and they have not been able to consistently trigger the error
16:18 lumberJ even on the same set up that initially cause the crash
16:18 lumberJ fyi: i run 0.4.16 and both mods are up-to-date from github
16:19 lumberJ *stable
16:20 stormchaser3000 joined #minetest
16:20 lumberJ anyways, i posted an issue on basic_machines github, but i just thought I would float this out incase anyone else has seen this problem before

17:42 deltasquared joined #minetest
17:43 deltasquared stupid question time, if an entity mesh file defines a point to be exactly +1.0 above the model origin, and I use that for an entity definition and I don't set the visual size properties, will the model scale default to that point being exactly 1.0 nodes above the entity's position?
17:44 deltasquared rationale: wanting to set visually accurate distances between two entities, where one just touches the other

18:38 rubenwardy quite a lot of interest
18:38 deltasquared I'm still pissed I didn't manage to go to bristol in the end... so freaking close (globally speaking)
18:39 rubenwardy there were a surprising number of people wanting to use it for education
18:39 rubenwardy like, teaching kids to code
18:39 deltasquared rubenwardy: that doesn't suprise me at all
18:39 sfan5 me neither
18:39 rubenwardy one had even done a hack event in manchester
18:40 deltasquared if I ever had the opportunity to show visualisations in minetest for something dissertation-related I wouldn't waste a moment
18:41 rubenwardy few people asked how we were funded O_o

18:43 deltasquared hmm, I wonder if there could be a situation where you'd be paid for MT dev... possibly something educational related, I can't see any other avenues where someone would pay you for it because it's important to them
18:43 rubenwardy you'd need a legal entity for that
18:44 rubenwardy and also people interest to pay for it
18:45 rubenwardy it suspect education-related would be the most likely \o/
