is there a way to get a raycast for what a player is looking at? |

<bastrabun> Is there a way to express "This position is inside a block collision box"? |
| 12:32 |
ireallyhateirc |
you mean the default collisionbox or any collisionbox |
| 12:33 |
ireallyhateirc |
the center of a node is at integer positions and span +/- 0.5 nodes in each direction from that center |
| 12:35 |
MTDiscord |
<bastrabun> Any collisionbox. Think stairs, slabs, fences, ... all kinds of weird collisionboxes. |
| 12:39 |
MTDiscord |
<luatic> by express you mean check whether a position is inside a collision box? |
| 12:39 |
MTDiscord |
<bastrabun> yes |
| 12:40 |
MTDiscord |
<luatic> what i'd do is get node collision boxes in a +-1 radius, then iterate over all of them and check whether the point is in any of them |
| 12:40 |
MTDiscord |
<luatic> radius by taxicab distance |
| 12:40 |
MTDiscord |
<luatic> so a cube |
| 12:54 |
MTDiscord |
<bastrabun> A fence block is composed of multiple collisionboxes depending on where it connects. If there is no connection in one direction, but I iterate over all defined collisionboxes, I'll detect wrong |
| 12:58 |
MTDiscord |
<luatic> if you're running a somewhat recent engine version you have core.get_node_boxes |
| 13:01 |
MTDiscord |
<bastrabun> 5.10.0, so it's available. Thanks, I'll try that : ) |

<warr1024> It got paramatted because people thought it didn't look pretty and during the paramat era, that was apparently more important than usability. Maybe not anymore. |

@luatic taxicab distance with fixed radius defines a diamond (octahedron) actually, not a cube; the one that defines a cube is the Chebyshev distance |
| 15:29 |
|
silverwolf73828 joined #minetest |
| 15:29 |
MTDiscord |
<luatic> pgimeno: right, i confused the two. i meant the infinity-norm (chebyshev). |
| 15:30 |
Krock |
taxicab sounds like manhattan but with extra steps |
| 15:30 |
pgimeno |
I thought manhattan and taxicab were two names for the same thing |
| 15:31 |
MTDiscord |
<luatic> yes |

wsor4035: fwiw I bet optimizing the models used in homedecor would also save some performance. no idea what this thing is but it's 8k vertices per thing https://0x0.st/8sOy.png |
| 15:37 |
sfan5 |
(might be pipeworks actually?) |
| 15:39 |
sfan5 |
I suppose culling "big" objects individually could also make sense |
| 15:42 |
MTDiscord |
<wsor4035> Looks like pipeworks pipes. I can only do the most basic of model edits, so someone else will have to submit a pr for that |

<csperson> can it be made such that there isn't that slight rotation movement when items are placed? |
| 16:02 |
|
SFENCE joined #minetest |
| 16:02 |
ireallyhateirc |
The common problem with beginner level 3D models is duplicated topology. Blender often creates that upon rewinding an action (which is useful) but some don't know that. |
| 16:03 |
ireallyhateirc |
Doing -> edit mode -> pressing "A" -> merge by distance |
| 16:04 |
ireallyhateirc |
will remove most of that duplicated topology. I saw an armchair in SweetHome3D that had 3K vertices out of which 2K was duplicated vertices |
| 16:05 |
ireallyhateirc |
@csperson, you mean my shelf thing or generally? |
| 16:06 |
MTDiscord |
<csperson> the shelf thing. Why would i mean generally? Ig discord replies dont show over irc bridge, but yeah it was in reference to the shelf |
| 16:08 |
|
Desour joined #minetest |
| 16:08 |
ireallyhateirc |
either way that's a problem with entities having interpolated rotation only which is a Luanti problem. Apparently I could add some hacks with attachments and bones but this sounds like a pain to do. |
| 16:09 |
ireallyhateirc |
I could make it so only the item affected is rotated and not everything |
| 16:11 |
MTDiscord |
<csperson> Hmm. I suppose that makes sense. I wonder if it'd be possible to fix that in the engine itself then. Or rather, reasonably possible. |
| 16:12 |
ireallyhateirc |
it'd be possible but you need a happy volunteer to do that and I don't know C++ so there's that |
| 16:13 |

8K vertices? lol |
| 16:39 |
ireallyhateirc |
I'll have a look |
| 16:40 |
ireallyhateirc |
it's like the toothbrush https://www.youtube.com/watch?v=H7E3G1PEOAY |
| 16:43 |
ireallyhateirc |
Any particular pipe that's so heavy? |
| 16:43 |
Krock |
it's galvanized square steel. that's why it's so heavyweight. |
| 16:46 |
ireallyhateirc |
the directory has low-poly and high-poly models |
| 16:47 |
ireallyhateirc |
and there's this: local polys = "" |
| 16:47 |
ireallyhateirc |
if pipeworks.enable_lowpoly then polys = "_lowpoly" end |
| 16:47 |
ireallyhateirc |
the low poly variants have decent poly numbers for a blocky game |
| 16:47 |
ireallyhateirc |
the high poly valve is 2K vertices |
| 16:50 |
ireallyhateirc |
So looks like you can simply switch to lowpoly with a setting |
| 16:50 |
|
cryne7 joined #minetest |
| 16:51 |
MTDiscord |
<wsor4035> if they look the same, maybe should just switch to those by default/toss high poly |
| 16:52 |
|
bodiccea joined #minetest |
| 16:52 |
MTDiscord |
<wsor4035> maybe the low poly can be optimized more? could always go for a bit more of a blocky look rather than round to save i guess |

sid0 joined #minetest |

ireallyhateirc |
first I'd switch to low-poly by default and then bother with optimising that |
| 17:04 |
ireallyhateirc |
the low-poly ones appear to have honest poly-count |
| 17:06 |
ireallyhateirc |
the low poly valve has 100 triangles, the high poly one has 3600 triangles |
| 17:07 |
ireallyhateirc |
Personally I'd just trash the high-poly models because it just badly clashes with the rest of the game |
| 17:08 |
ireallyhateirc |
and they don't bring much gameplay |
| 17:09 |
ireallyhateirc |
Also there's no much to optimise in the low-poly models |

just throwing https://github.com/mt-mods/pipeworks/issues/148#issuecomment-2564816600 out there to see what people think/avoid wasting my time making a polished version for testing in game |
| 19:23 |
Krock |
that's going into a perfect direction |
| 19:23 |
ireallyhateirc |
the real challenge is keeping one artstyle for all pipes |
| 19:24 |
MTDiscord |
<wsor4035> insert warnings all over that im a programmer, not an artist/modeler. just know enough to make the occasional edit/get by |
| 19:24 |
Krock |
I didn't even remember that there were such tubes in pipeworks. All that mattered was the item transportation tubes, which are very low poly. |
| 19:24 |
ireallyhateirc |
In the end I'm going to make some pipes for my perfect city game so I could give it a try |
| 19:26 |
ireallyhateirc |
I usually use octagons as circles though |

<wsor4035> thanks, i refer to my previous comment of not being good at 3d modeling |

My mid-poly character has 15K tris |

Krock |
Is there yet a yanderedev toothbrush mod? |
| 20:38 |
ireallyhateirc |
I could make one |
| 20:39 |
ireallyhateirc |
using 15K tris for a well designed character is fine, but 5K for a toothbrush/pipe is ridiculous |
| 20:41 |
ireallyhateirc |
sfan5, are these Luanti's builtin warnings or are you using something custom for that? |
| 20:41 |

my own code, might make it into Luanti if I polish it |

how into node protection? |
| 23:53 |
ireallyhateirc |
the API mentions core.is_protected but I couldn't find any info on how to get a node protected |
| 23:57 |
MTDiscord |
<wsor4035> thats on you to implement |
| 23:57 |
MTDiscord |
<wsor4035> most everyone uses areas |
| 23:59 |
MTDiscord |
<wsor4035> is_protect like is_creative_enabled is a function meant to be overridden by mods |
| 23:59 |
ireallyhateirc |
so it's a placeholer function that mods can overwrite? |
