03:15 Quiark       are worlds in minetest infinite?
03:36 sofar        nope
03:38 Quiark       ook. Are they lazily generated?
03:43 sofar        lazily?
03:43 sofar        the map parts are generated on demand
03:43 Quiark       yeah on demand is just a different word for 'lazily'
06:18 librebob[m]  how big are they
06:25 ANAND        approx. 31000x31000x31000
06:25 VanessaE     no, closer to 64000^3
06:26 VanessaE     (with most of Y > 40ish being just air by default)
06:36 ANAND        oh right, 31000 is the distance from 0,0,0.
06:36 VanessaE     mmhmm
06:37 VanessaE     like 31987 or something
12:01 mycraft1     I wish they would someday be 2147483648 x 2147483648 x 2147483648 (theoretical limit, lazily generated) but that's just wishful thinking
12:02 ChimneySwift lol, I'm not sure how you'd even utalize that much map
12:05 mycraft1     ok what I'm really wishing for, is that If I start walking in one direction, that human lifetime will not be enough to reach the theoretical limit (e.g. limited only by available diskspace etc.)
12:05 mycraft1     but then again
12:05 ChimneySwift mhm
12:06 mycraft1     I can't contribute much dev. resources hope nore developer ever finishes his job of expanding mt to larger worlds
12:07 Cornelia     I don't remember the reason why worlds have restricted sizes.
12:08 mycraft1     ok, I'm talking too much back to building
12:08 ChimneySwift because of the limits of the sqlite database used to store it afaik

12:09 rubenwardy   There we are
12:09 ANAND        :D
12:09 rubenwardy   Hmmm
12:09 rubenwardy   Minetest relies on a 1 to 1 id for blocks
12:10 rubenwardy   So a single number is used to look up a 16x16 area, and only one will be returned
12:10 Cornelia     Block... "Prototypes" or block present in the world
12:10 rubenwardy   To make the world bigger you could increase the size of this id
12:10 rubenwardy   Or you could change it to a hash map and then you'd be limited only by the precision of the vector
12:11 Cornelia     You could beat your lookup function and create different ID spaces
12:11 rubenwardy   Which is v3f32, CBA to work out the maths
12:11 Cornelia     *nest
12:11 rubenwardy   That's the same as making a bigger id
12:12 Cornelia     Yea, but you could do it only as needed.
12:12 rubenwardy   Sounds like a variable length id
12:12 rubenwardy   Which would work
12:12 rubenwardy   However it would be a lot slower
12:12 rubenwardy   A hash map is a much more efficient method
12:12 rubenwardy   As the id is fixed length
12:12 rubenwardy   Well, hash now
12:13 rubenwardy   But you can have multiple mapblocks per hash and you use the position to find the correct one
12:13 rubenwardy   This is definitely a non-trivial change
12:13 rubenwardy   And this doesn't benefit the majority of users
12:13 rubenwardy   There's only 2 valid reasons for bigger maps:
12:14 rubenwardy   1. Making to life scaled reconstructions. This projects usually require a ton of automation
12:14 rubenwardy   2. Dick comparing
12:15 Cornelia     Eh. I can think of two others.
12:15 Cornelia     One mechanical and one aesthetic.
12:16 Cornelia     The first, to use MC as an example, some large capacity servers have groups of players that travel very far (> 50k) from spawn to build their bases. Generally on PVP servers only.
12:17 Cornelia     The second, it's aesthetically more pleasing to be able to travel in one direction as long as the player desires instead of being forced to change direction at some point.
12:17 Cornelia     But, like you said, most players probably won't benefit.
12:17 Cornelia     Because they're unlikely to go that far.
12:28 librebob[m]  does anyone know how to tame boar on mods_redo?

13:31 Quiark       rubenwardy, imagine a hashmap with only one entry per bucket ... and exploring a world where some 16x16 blocks have collisions
13:31 Quiark       would be interesting :D also educational about the likelihoods of hash collisions
13:34 rubenwardy   Heh
13:34 rubenwardy   Currently it's not really a hash - there are no collisions
13:34 rubenwardy   Afaik
14:09 Krock        Quiark: nobody needs infinite worlds
14:09 Krock        even those in No Man's Sky are not infinite
