does the minetest client run on raspberry Pi 4 ? |
| 16:53 |

yes |

it runs wherever Linux runs |

Krock: I assumed it builds, mostly curious about performance |
| 16:55 |
Ingar |
but, I guess we'll find out ;) |
| 16:55 |
Krock |
well yeah.. 10 FPS maybe? |
| 16:56 |
Krock |
but RPI 6 will likely beat my current PC's specs, so maybe in a few years |
| 17:00 |
Ingar |
in a few years mt should be raytraced ;) |
| 17:01 |
Krock |
yeah sure, I also dream of unicorns on rainbows |
| 17:06 |
Wuzzy |
how much do i have to worry about performance if I lower the setting "liquid_update"? |
| 17:06 |
Wuzzy |
to a value like 0.1, for example (default=1.0) |
| 17:07 |
Krock |
10x more time spent in updating liquids (spreading) |
| 17:07 |
Wuzzy |
and if liquids don't spread atm? |

| 17:08 |
Krock |
the workload is the same, but lowering that will also increase the search interval for possible spreading |
| 17:08 |
Wuzzy |
is this a problem? |
| 17:08 |
Wuzzy |
would it be realistic to enable a low value as game-wide default? |
| 17:10 |
Krock |
it'll only be causing more sort-time load on modified mapblocks and flowing liquids |
| 17:10 |
Krock |
dunno. try it |
| 17:11 |
Krock |
the update queue is also size-limited, so it doesn't spend too much time on it |
| 17:12 |
Wuzzy |
ah. so if there's too many liquids that want to flow at once, some liquids are just ignored? |
| 17:12 |
Krock |
delayed |
| 17:13 |
Wuzzy |
ok |
| 17:13 |
Wuzzy |
this sounds like it shouldt destroy performance then. cool |
| 17:15 |
Krock |
it could cause real hard client and server lags until the liquids are spread (no changes) |
| 17:16 |
Wuzzy |
bummer |
| 17:18 |

just try it |

how complete is this ? https://github.com/minetest/minetest/blob/master/doc/client_lua_api.txt |
| 18:05 |
Krock |
unstable, and only usable for chat stuff |
| 18:06 |
kurtzmusch |
but i mean, the documentation itslef |
| 18:06 |
kurtzmusch |
does it cover like 90% of the client api? |
| 18:11 |
sfan5 |
it's the reference for the client api, it covers everything that exists |
| 18:11 |
Krock |
for certain objects and structures you'll need lua_api.txt |
| 18:11 |
kurtzmusch |
oh, ok |
| 18:12 |
kurtzmusch |
yes, i use lua_api a lot |
| 18:12 |
kurtzmusch |
thought about taking a look at the client-side of things |
| 18:14 |
kurtzmusch |
i was hoping i could manipulate player and entity stuff = (... at least we get particles... imo those shoul be done clientside in most cases |

Hi I would like to build a Boat. How do I stop the water from being in boat below the water line? |
| 19:56 |
calcul0n_ |
fill a big cube with dirt then remove it and only keep the walls |
| 19:56 |
calcul0n_ |
this way you can build it on a dry floor and remove the walls when it's done |

Someone thinks you should read the API docs, please go to: https://github.com/minetest/minetest/blob/master/doc/lua_api.txt |
| 20:13 |
kurtzmusch |
yes |
| 20:13 |
kurtzmusch |
the true question is: is it faster than placing schematics? |
| 20:34 |
|
LMD joined #minetest |
| 20:36 |
tacotexmex |
Can’t be, right? |
| 20:37 |
BluedelaOof[m] |
it would probably be a decoration type, yes? |
| 20:38 |
BluedelaOof[m] |
and for clarification I meant during world generation |
| 20:41 |
kurtzmusch |
you would probably need to call it withing minetest.register_on_generated() |
| 20:41 |
tacotexmex |
It’s not a deco type as it’s spawned with minetest.spawn_tree. If only decorations could contain functions… |
| 20:42 |
kurtzmusch |
then, using noise or just math.random combined with biome data decide to call spawn_tree |
| 20:42 |
tacotexmex |
I recently realized I need to learn voxelmanip anyway however. |
| 20:43 |
kurtzmusch |
you would probably need to get a voxelmanip object to read a big area for eficiency |
| 20:43 |
kurtzmusch |
yeah, its quite simple actually |
| 20:44 |
kurtzmusch |
just an object with methods to write back to the map or to fetch from the map |
| 20:45 |
kurtzmusch |
but i think spawn_tree writes directly to the map |
| 20:45 |
kurtzmusch |
so you only need the voxelmanip to check for height and type of node i guess |
| 20:46 |
kurtzmusch |
im learning this stuff too. this week iv been working on a mapgen |
| 20:46 |
tacotexmex |
Speaking of voxelmanip I wanted to mix stone with two other nodes evenly the other day. Since stone is such a common node this routine will be performed constantly. How to optimize it in terms of area size etc? |
| 20:54 |
kurtzmusch |
id say to get whatever size the mapgen gives to you as this will give you an already filled voxelmanip |
| 20:55 |
kurtzmusch |
the defualt size if you didnt change in options is (80+32)^3 |
| 20:55 |
tacotexmex |
So default is good then |
| 20:56 |
tacotexmex |
I’m currently using the stratum ore type for this purpose so any performance increase is welcome lol |
| 20:57 |
kurtzmusch |
yeah, its a cube with side 112 nodes |
| 20:57 |
kurtzmusch |
oh making it an ore might be even faster lol im not sure |
| 20:58 |
kurtzmusch |
this way you dont even need to bother with voxelmanip |

| 22:12 |
tacotexmex |
kurtzmusch: I’ve always thought that voxelmanip is the blazing fast but complex approach. I hope I’m right :/ |
| 22:13 |
kurtzmusch |
tacomex, iv never done ores, but since its something you register and the engine will place itself later im assuming its the fastest |
| 22:14 |
kurtzmusch |
using vmanip takes at least 200ms just to load a mapchunk and then write it back without changing anything or generating anything, at least on my computer |
| 22:16 |
kurtzmusch |
same thing with registering decorations x placing schematics yourself with vmanip.... again, never really compared those but i think that the most the engine does by itslef the better/faster |
| 22:17 |
kurtzmusch |
if you are going to try to use vmanip remember to recycle your buffers, otherwise you may run into lua crash out of memory |
| 22:18 |
kurtzmusch |
it also helps with speed a tiny bit |
| 22:19 |
tacotexmex |
Sounds plausible. What’s with this recycling thing? |
| 22:21 |
kurtzmusch |
you just use the same array to store the data instead of alocating again and again |
| 22:22 |
Wuzzy |
tacotexmex: just use the buffer parameter. lua_api.txt explains it |
| 22:23 |
Wuzzy |
voxelmanip is indeed fast, but it only makes sense for changing large amoutns of nodes |
| 22:23 |
sfan5 |
Lua will clean up after you anyway, unless you leave the buffers in a global variable somewhere |
| 22:23 |
sfan5 |
recycling buffers is mostly for performance |
| 22:23 |
Wuzzy |
global variables should be avoided like the pest, normally |
| 22:24 |
Wuzzy |
its super easy to pollulte global lua namespace ? |
| 22:24 |
kurtzmusch |
sfan5 its possible to alocate faster than the garbage collector does its thing and then lua crashes saying you exeeded 1gib = ( |
| 22:25 |
sfan5 |
you must be using a lot of vmanips at once then |
| 22:25 |
Wuzzy |
I'm not a racist, but calling voxelmanip does not make sense if you only want to change one node. Use set_node. it's probably even faster in this case. |
| 22:25 |
kurtzmusch |
only one in the on_generated |
| 22:25 |
kurtzmusch |
i was calling a lot of noise too |
| 22:26 |
Wuzzy |
when in doubt, compare different approaches and measure time |
| 22:40 |
kurtzmusch |
tacotexmex, if you want examples, here is somthing ive been toying with this week https://notabug.org/Kurtzmusch/ether_lands/src/master/init.lua#L112-L135 it highlights where i recycle the buffers |
| 22:48 |
tacotexmex |
Interesting. Aether inspired huh? :) |
