Hmm. My instinct on seeing that question would've been to point to the /emergeblocks documentation. Technically not what was asked, but I'm used to seeing XY problems, and that's where my brain would've gone. |

(The question about generating empty blocks, I mean.) |

<localhost> How i can do "sleep" (wait some seconds) inside function? |
| 20:28 |
[MTMatrix] |
<localhost> Just for slowdown on_place speed |
| 20:29 |
calcul0n |
use minetest.after() |
| 20:29 |
[MTMatrix] |
<localhost> wait, but if only for call outside function? |
| 20:29 |
[MTMatrix] |
<localhost> wait, but it only for call outside function? |
| 20:29 |
calcul0n |
a real sleep would block the whole engine |
| 20:30 |
calcul0n |
you'll have to write things differently but it's not very hard |
| 20:31 |
[MTMatrix] |
<localhost> eg. minetest.after(5, func), but in my case if i do on_place = minetest.after(5, func), it causes error |
| 20:32 |
calcul0n |
yep, that would only call after at registration time |
| 20:32 |
calcul0n |
you need on_place = function(...) minetest.after(5, func) end |
| 20:33 |
[MTMatrix] |
<localhost> oh.. thanks |

<rollerozxa> erle: we made a little discovery that since [png blindly passes on the image data to irrlicht as an in-memory file, it works for inlining images of any format, not just PNG |
| 20:35 |
erle |
ROllerozxa this makes the grammar even stupider, but also this is useful lol |
| 20:36 |
MTDiscord |
<savilli> sfan5: fixing that is trivial. Just replace __temp_png with __temp.png. |
| 20:37 |
MTDiscord |
<rollerozxa> (no, it won't, irrlicht doesn't care about file extensions, only the header) |
| 20:37 |
erle |
ROllerozxa i guess that means you can pretty much start using unicode_text on signs without doing the dynamic media dance |
| 20:37 |
MTDiscord |
<rollerozxa> yep |
| 20:37 |
erle |
i mean, it's super fucking ugly (i actually cautioned against adding anything like [png or [tga or so), but it's obviously useful. so have fun with it! |
| 20:38 |
MTDiscord |
<savilli> It doesn't care only because __temp_png doesn't have an extension. |
| 20:39 |
erle |
savilli are you playing “let's break some useful feature because itwas not intended” or what? |
| 20:39 |
MTDiscord |
<rollerozxa> the fun police has arrived, thankfully they can't stop us |
| 20:39 |
erle |
FUN is banned! |
| 20:39 |
erle |
btw, i actually think the dynamic media API is pretty stupid for stuff like signs and so on, for all the racy conditions. |
| 20:40 |
erle |
it would be much better if this would work more like a web browser, where you can reference a texture and the client loads it later. |
| 20:40 |
MTDiscord |
<savilli> I'm just eating my popcorn. You guys are very entertaining with that tga discussion. |
| 20:40 |
erle |
at least for signs |
| 20:40 |
erle |
savilli i am amused too. i mean the whole minetest.encode_png() and [png was kinda not too well-thought-out in the first place. |
| 20:41 |
erle |
this is probably the funniest bug i have seen in a while |
| 20:41 |
erle |
i think since the object oriented enchanted book probably |
| 20:41 |
erle |
the bug was like this: books needed to be enchantable in mcl2 to have an enchantment. so … you could use a stack of books. and enchant the stack using one book. |
| 20:41 |
erle |
because nothing prevented you from enchanting stacks of items |
| 20:41 |
celeron55 |
obviously the "png" in the texture modifier doesn't refer to the image format but actually means Potentially Not a Graphic |
| 20:42 |
erle |
and weapons are not stackable in mcl2 |
| 20:42 |
erle |
IF ONLY someone had warned the implementors and said “you need to have a grammar for texture modifiers that is context-free or regular” |
| 20:42 |
erle |
oh wait, i did that |
| 20:42 |
erle |
and i think luatic did too? |
| 20:43 |
MTDiscord |
<savilli> I thought it means Pleasure Not Guaranteed |
| 20:43 |
erle |
anyway, this is the most monkey's-paw thing i have seen so far and evidently useful to implement a signs mod. |
| 20:43 |
erle |
because so far the problem is that you need lots of bookkeeping for the players and the textures |
| 20:44 |
erle |
with this way however, you can just replace whatever generates your texmods with unicode_text and call it a day. well, i need to fix 1 bug in the bidi algorithm (or disable it) i guess. you'll find it soon enough (uniess i get there first). |

ROllerozxa i have learned from my question “can i change the main menu script from a mod” that FUN is best kept to oneself to not invite the FUN POLICE :P |
| 21:25 |

by which i do mean of course that i have no idea how to achieve code execution via a crafted ogg vorbis file |

but readers of CVE-2020-20412 might be able to figure that out! |
| 21:28 |
erle |
(i am not good with computers) |
| 21:29 |
[MTMatrix] |
<localhost> so... the 'while true do if math.random(1,10000) < 5 then break end end' very bad idea for use? |
| 21:29 |
erle |
for what use |
| 21:29 |
erle |
heating your room, it might be useful |
| 21:30 |
erle |
depending on speed of device obv |
| 21:30 |

<localhost> ahahah |
| 21:30 |

and bias of RNG |

or maybe two |

<localhost> maybe, but no warranty answer |

okay, are you on windows? |

what's your version of libvorbis |

i mean the one you compiled minetest with |
