hah, minecraft doesn't use opportunistic encryption |
| 04:04 |
est31 |
SRP is opportunistic by design :) |

hi folks, I'm fixing up the mcimport project a bit and I'm running into a conversion issue that I can't find any good docs/details on, as the mcimport project direcly writes out the map.sqlite and thus does all the encoding on the fly - it's not covered by the e.g. lua api docs |
| 04:24 |
sofar |
anyway, I'm trying to have it convert mesecons pressure plates |
| 04:24 |
sofar |
but apparently the plates I'm converting now are saved without a node timer attached to it |
| 04:24 |
sofar |
so after conversion they never activate |
| 04:25 |
est31 |
sofar, the map format is documented at https://github.com/minetest/minetest/blob/master/doc/world_format.txt |
| 04:25 |
sofar |
so now I'm trying to confirm that node timers are added at the end of each block, and how the encoding goes |
| 04:26 |
sofar |
aw heck that's nice |
| 04:29 |
sofar |
I should extend my inspector to show node timers.... |

how weird. node timers are stored without identifying information in a node |
| 06:01 |
* sofar |
wonders how that works |

well thanks to est31 I now have functional pressure plates converted from minecraft, wew |

Guest20724, (aka ShadowNinja) : seen your comment on github on #3390. I think we should have something similar for minetest's cpp/h source files too. Then nobody has to update copyright years or so. |
| 19:57 |
ShadowNinja |
est: Cool. IANAL though. |

est: thanks for the node timer encoding pointers yesterday... managed to get pressure plate conversion result in working pressure plates! |
| 20:16 |
est |
nice! |
| 20:16 |
sofar |
yeah, so far the conversion is getting quite good |
| 20:17 |
sofar |
I'm gonna try noteblocks next, that will be interesting |
| 20:17 |
sofar |
I think I can even convert the pitch properly |
| 20:18 |
sofar |
it's slow, though, lol |
| 20:18 |
sofar |
my old minecraft world takes 9+ hours to convert |
| 20:20 |
est |
then speed it up :) |
| 20:20 |
sofar |
I'd have to rewrite it in C |
| 20:20 |
sofar |
considering conversion is going to be a one-time thing for most people... nahhhhhh |
| 20:21 |
sofar |
(don't get me wrong, I love rewriting code in C....) |
| 20:21 |
est |
what is it written in right now? |
| 20:21 |
sofar |
python |
| 20:21 |
sofar |
github.com/sofar/mcimport |
| 20:22 |
sofar |
it's not originally my own project, I'm just taking it a level further |
| 20:22 |
est |
perhaps try to find bottlenecks? |
| 20:23 |
sofar |
well it's easy to spot them - each node individually needs to be remapped from it's old location in the block to the new one, while also being translated from old node type to new node type, and preserving special attributes |
| 20:24 |
sofar |
I mean, my old world is 850000+ mc blocks -> nearly a billion nodes? |
| 20:24 |
sofar |
well over, even, 3.5 billion nodes |
| 20:25 |
sofar |
I'd rather continue making the conversion as complete as I can first |
| 20:25 |
sofar |
with a focus on "playable" - no "shim" blocks that don't work |
| 20:30 |
est |
one thing to find out would be whether it uses arrays |
| 20:30 |
est |
for the lookup |
| 20:31 |
|
Gael-de-Sailly joined #minetest-dev |

or whether its more ... "higher level" data structures, with penalties at lookup |
| 20:31 |
Calinou |
sofar, run it with PyPy |
| 20:31 |
Calinou |
(make it PyPy-compatible first, of course) |
| 20:34 |
sofar |
I'm python-averse... so that'll force me to learn more python than I would want to admit ;^) |

any dev around for PR merging session? |
| 21:16 |
est |
kahrl, nore sfan5 ShadowNinja ? |
| 21:26 |
est |
#3245 for example, I think it can be merged except for the obj -> player rename |
| 21:26 |
est |
it should probably be player_obj or player_ref |
| 21:26 |
est |
bc player can either mean player name or player object |
| 21:28 |
est |
so thats the first one : https://github.com/minetest/minetest/pull/3245 |
| 21:28 |
est |
second one on the list |
