How do I invert mouse? Currently when I move the mouse away from me, my character looks up. I would rather he looks down. I couldn't find anything here: https://wiki.luanti.org/Controls |
| 00:23 |
cheapie |
lmat: Does the "invert mouse" setting (Controls→Keyboard and Mouse) not do what you want? |
| 00:24 |
lmat |
This is what I see after I click "Controls": https://imgur.com/a/cxi9woA I don't see "Keyboard and Mouse". |
| 00:24 |
cheapie |
In the settings menu, not the bindings |
| 00:25 |
lmat |
OHHH, I need to exit the game! I see settings now, thank yo! |
| 00:25 |
lmat |
lol, when I started up, I directly started looking down at the ground xD |
| 00:25 |
lmat |
maybe I'm getting used to UN-inverted... maybe I should go back |
| 00:27 |
lmat |
Oh great, I got my password changed \o/ I think maybe the problem was that the password had a space in it. I was doing /setpassword lmat "this password" and I could never log in using "this password" (maybe I needed to keep the quotation marks?) Instead, I did /setpassword lmat lmat logged in as lmat, then used the GUI to change the password to one with spaces. |
| 00:28 |
lmat |
Krock: Thank you for your help the other day with this <3 |

How do I make bronze? Am I doing it wrong? https://imgur.com/a/BzhrSOv |
| 00:30 |
lmat |
(that's copper and tin) |
| 00:30 |
MTDiscord |
<vejou> what does it say with the recipes tab |
| 00:33 |
lmat |
vejou: there are only two recipes for bronze in there: cook bronze dust, Bronze block -> bronze ingot. When I consult a Crafting Guide Sign, it shows only one recipe: copper+tin->bronze |
| 00:33 |
MTDiscord |
<vejou> what does it say for bronze dust |
| 00:34 |
MTDiscord |
<vejou> you might be supposed to make bronze dust first |
| 00:35 |
lmat |
vejou only one recipe: bronze ingot -> bronze dust |
| 00:35 |
MTDiscord |
<vejou> what does it say for how to craft bronze dust |
| 00:35 |
MTDiscord |
<vejou> is there no crafting recipe for it |
| 00:40 |
lmat |
vejou It says bronze ingot -> bronze dust on the Crafting Guide sign. When I go to my inventory then click "Recipes" on top and look up bronze dust, it says "No recipes." |
| 00:41 |
lmat |
vejou Does that answer the question? Sorry if I'm missing something obvious |
| 00:44 |
|
liceDibrarian joined #minetest |
| 00:44 |
MTDiscord |
<vejou> it does answer it |
| 00:44 |
MTDiscord |
<vejou> thats weird |
| 00:44 |
MTDiscord |
<vejou> from that it sounds like you cant make bronze dust at all unless its a modded tool that does it |
| 00:45 |
lmat |
vejou I used to be able to make bronze ingot no problem from tin ingot and copper ingot :'( |
| 00:45 |
lmat |
vejou I think I still can in single player, but on my server it doesn't work for any players. |
| 00:46 |
cheapie |
Did you install a mod (like techage) that replaces that recipe, or remove the mod that was providing it previously? |
| 00:49 |
MTDiscord |
<vejou> if you want the same recipe back you could probably put a mod in that registers it |
| 00:50 |
MTDiscord |
<vejou> even if you type the program yourself |
| 00:58 |
lmat |
cheapie: Excellent question xD |
| 01:01 |

lmat |
Any other ideas about how to debug this? Say I did have a mod that added it, then I removed the mod. What then? What is keeping minetest from honoring the built in recipe? Should I grep my mods to see if any of them are borking the bronze recipe? |
| 01:18 |
MTDiscord |
<luatic> Bronze is built into MTG, so you probably did not remove it. The former (you installed a mod that replaces the recipe) is more likely. Grepping for that is the way to go. (You could also hook into the recipe registration function with a first-loaded mod but eh.) |
| 01:23 |
lmat |
cd mods && \grep -riC 2 bronze . | pastie; shows https://paste.rs/8lgyq. Nothing there looks suspicious to me except maybe line 64: "technic_cnc.register_all("default:bronzeblock",..." ? |

luanti vs. minetest in google trends will be interesting to follow: https://gcdnb.pbrd.co/images/3uMr1xo2vO0D.png?o=1 |
| 12:37 |
ireallyhateirc |
"Luanti (formerly Minetest)??? Huh, what's that *googles minetest*" |
| 12:44 |
ireallyhateirc |
lol, when I duckduckgo "minetest" I get two websites |
| 12:44 |
ireallyhateirc |
one is luanti.org and the other is minetest.org |
| 12:47 |
MTDiscord |
<zmv7> The forbidden site 💀 |
| 12:48 |
ireallyhateirc |
now that may be a little confusing |
| 12:49 |
ireallyhateirc |
google doesn't appear to make that mistake |
| 12:50 |
ireallyhateirc |
Minetest peaked after the devs added rats |
| 12:50 |
ireallyhateirc |
everything after rats (including bug fixes and API improvements) were a mistake :D |
| 12:51 |
sfan5 |
good news: minetest classic has rats |
| 12:51 |
ireallyhateirc |
I'm going to make a dedicated rats++ mod one day |
| 12:55 |
ireallyhateirc |
seriously though I never played Minetest back when it had rats, I'm simply making fun of the other website. But yeah, rats are a vital feature. |

on_punch only has puncher but projectiles have an entity and a player owner. Many send their owner as puncher making them undetectable. How should it be done correctly? In many cases you need to know both the player and the what projectile it is or if he hit directly. |

hi. anyone here with a lua problem for me to solve? im bored |
| 20:43 |
Krock |
fishmongler: all advent of code puzzles |
| 20:43 |
erle |
fishmongler i have one |
| 20:44 |
erle |
fishmongler my xcam mod currently hangs the server for 20 seconds doing 100k raycasts with default settings. while you can turn of the distance blur and reduce the resolution to make it basically instant … could you make it async? patches welcome |
| 20:46 |
erle |
fishmongler for reference, here is xcam: https://content.luanti.org/packages/erlehmann/xcam/ |
| 20:52 |
fishmongler |
erle: you are software rendering correct? |
| 20:52 |
|
Verticen joined #minetest |

erle |
fishmongler yes. this is a server side raytracer mod. |
| 20:52 |

sorry i cannot follow links or even read lua_api.txt on this machine, this is literally an ansi terminal |
| 20:52 |
|
shaft joined #minetest |

fishmongler do you have git? |
| 20:53 |
shaft |
I once wanted to make a voxel game and call it Mineshaft. Someone else already had the same idea: https://github.com/AiTechEye/Mineshafts-prototype2 I'm so unoriginal. |
| 20:53 |
erle |
fishmongler you can get the source with: git clone https://git.minetest.land/erle/xcam.git |
| 20:53 |
fishmongler |
on this? sadly no |
| 20:53 |
erle |
fishmongler do you have curl or so? |
| 20:54 |
fishmongler |
i can only curl without tls here. dont ask why |
| 20:54 |
fishmongler |
ancient linux terminal im stuck with at a bar |
| 20:54 |
fishmongler |
so anyway, how realtime must the xcam render be? |
| 20:55 |
fishmongler |
because scheduling the rendering over many globalsteps as a coroutine is an obvious fix |
| 20:55 |
erle |
wait something is wrong |
| 20:55 |
erle |
fishmongler yes that would work |
| 20:56 |
fishmongler |
i assume xcam is something like cctv camera to texture modifier |
| 20:57 |
fishmongler |
do you render meshes as part of the software render? |
| 20:58 |
erle |
fishmongler it's literally a raytracer |
| 20:58 |
fishmongler |
these are an order of magnitude more complicated and might benefit from an imposter system |
| 20:58 |
erle |
it's a lua-based raytracer that abuses the raycasting of the engine (that you usually use for visibility or “did my laser hit”) |
| 20:58 |
erle |
you can make a picture of a scene |
| 20:58 |
fishmongler |
and you use minetests raycast api? |
| 20:59 |
erle |
yesss |
| 20:59 |
erle |
you have minetest on the system you are on? |
| 21:00 |
fishmongler |
does it do texture sampling? |
| 21:00 |
fishmongler |
oh i know |
| 21:00 |
fishmongler |
doing a node level bresenham line walk might be more efficient than a raycast in some scenarios |
| 21:00 |
fishmongler |
especially if you render solid color blocks and dont texture map |
| 21:01 |
erle |
i think the idea of a photo being exposed is established well enough in real-world lore |
| 21:02 |
fishmongler |
no though i should compile minetest for this one day (as a challenge) |
| 21:02 |
fishmongler |
daguerrerotype =) |
| 21:02 |
shaft |
Unrelated to your discussion: Wasn't there some projectile library? |
| 21:02 |
erle |
as this picture establishes, i am putting textures on stuff (though not the ones that the things have, just some pixel noise) https://content.luanti.org/uploads/97de0f72cf.png |
| 21:03 |
erle |
shaft i am happy about bow2 lol |
| 21:03 |
fishmongler |
you could also try tile based rendering |
| 21:03 |
fishmongler |
and things like detecting which parts of the image must be recasted |
| 21:03 |
fishmongler |
consider also capturing the map data in the view frustum and using that in an async job to do rendering |
| 21:04 |
shaft |
Thank you, erle |
| 21:04 |
erle |
fishmongler i have considered a lot of things. you wanted a challenge. |
| 21:05 |
fishmongler |
do we have a generic async job system yet? sfan5's async mapgen was very close to that |
| 21:05 |
erle |
shaft bow_2_electric_bowgaloo :D |
| 21:05 |
fishmongler |
well im trying to help. as much as i can on a 2010 cellphone at a bar |
| 21:05 |
erle |
oh you are on a phone |
| 21:06 |
shaft |
No, me asking about a projectile library is unrelated to bow2 |
| 21:09 |
fishmongler |
being able to spawn lua vms without luajit would be very useful |
| 21:09 |
fishmongler |
im just bored and only irc works on this thing.. can you even run a minetest client in 256MB ram? |
| 21:09 |
fishmongler |
in theory i literally based the GLES2 cutoff on this device but failed to consider the ram |
| 21:16 |
fishmongler |
erle: have you profiled your code? sorry for obvious question |
| 21:20 |
fishmongler |
the only thing that comes to my mind is luajit specific optimizations, i could help with that |
| 21:21 |
fishmongler |
in general avoiding any and all GC churn (TNEW ir instructions) is orders of magnitude faster |
| 21:23 |
fishmongler |
maybe try to isolate the renderer code into a "unit test" kind of code with mock data/api and run it standalone with -jdump and see if it traces well |
| 21:32 |
erle |
fishmongler i am doing a lot of raycasts. simply doing it as a coroutine is enough i think. |
| 21:33 |
fishmongler |
i think calling into minetest to do it might be a significant bottleneck |
| 21:33 |
erle |
<fishmongler> in theory i literally based the GLES2 cutoff on this device but failed to consider the ram |
| 21:33 |
erle |
wdym? |
| 21:33 |
fishmongler |
enough to make some crazy lua-only solution viable |
| 21:34 |
erle |
no i mean wdym with the GLES2 cutoff? |
| 21:34 |
fishmongler |
if i were to implement this from scratch i'd just copy the surrounding map data w/ VoxelManip and dig into a 90s software rendering textbook |
| 21:35 |
fishmongler |
never mind the gles thing.. |
| 21:36 |
fishmongler |
i almost doxed myself there and the french bastard might still be lurking |
| 21:36 |
erle |
the male model? |
| 21:40 |
erle |
fishmongler why you think that raycasting in lua with cached voxelmanip is faster? |
| 21:40 |
erle |
or could be |
| 21:40 |
erle |
fishmongler like, i don't get it. is there some horrible overhead in calling engine functions i am not aware of? |
| 21:41 |
erle |
making a copy of the thing is good though, so the image does not get motion blur haha |
| 21:41 |
erle |
then again |
| 21:41 |
erle |
lol |
| 21:41 |
erle |
photographing a flying machine, it having ghost afterimages … |
| 21:41 |
erle |
that's something |
| 21:45 |
sfan5 |
fishmongler: the async job system existed before async mapgen |
| 21:46 |
fishmongler |
thing is you wont get exposure blur but more like what this crappy phone's camera does |
| 21:46 |
fishmongler |
interesting |
| 21:46 |
fishmongler |
so you can just spawn vms at will? |
| 21:48 |
fishmongler |
is this somewhere in lua_api or undocumented builtin? |
| 21:50 |
fishmongler |
erle: calling into the engine the usual way is slow becausde mt has to support puclua |
| 21:50 |
fishmongler |
and therefore do lua stack manipulation in distinct C calls, much much slower than an ffi call |
| 21:54 |
fishmongler |
there are scenarios in which doing some double arithmetic without crossing the lua/C boundary is faster |
| 21:54 |
fishmongler |
and doing stuff in bulk (such as operating on a voxelmanip) is faster than using a call per item (such as raycasts or get_node) |
| 21:54 |
fishmongler |
one part of this is a bit tragic. there is now a nice occlusion culler but its client side (?) |

fishmong1er do you have some example code about that? |
| 22:16 |
MTDiscord |
<luatic> in theory it could maybe be fast. i wouldn't bet on it. i'd say try it and see but it's frankly too much work to try it and see. |
| 22:16 |
MTDiscord |
<luatic> it might also be interesting to profile the C++ raycasts to see what can be optimized there. |
| 22:17 |
erle |
i think last time i checked vector metatables did not survive some async thing or so? |
| 22:17 |
erle |
maybe that was something else |
| 22:19 |
MTDiscord |
<luatic> they didn't, they do now |
| 22:22 |

since when luatic? |
