00:37 Electro_Cloud Hey guys, im back with another problem, my server just crashed...
00:38 Electro_Cloud When i checked the debug,txt the only ERROR that i see is "A serialization error occoured"
00:38 Electro_Cloud what should i try
00:38 Electro_Cloud I feel like this happened to me and i had to like delete a certain file... just forgot...
00:51 rubenwardy Electro_Cloud: are you using 5.0.0?
00:52 Electro_Cloud no, im using 5.1.1
00:52 rubenwardy ok
00:52 Electro_Cloud on the server and client side...
00:52 rubenwardy not sure sure then, that was a known bug in specifically 5.0.0

18:42 appgurueu Krock, regarding https://github.com/minetest/minetest/pull/9421
18:42 appgurueu what would you like me to improve?
18:43 appgurueu I would like to get it merged
18:43 Krock please use a field name that's at least half-way self-explaining
18:44 appgurueu In the API or in the code?
18:44 Krock ofc you do. everybody would like to get things merged
18:44 Krock both, if possible
18:44 appgurueu Hmm
18:45 appgurueu Looking at https://github.com/minetest/minetest/blob/master/doc/lua_api.txt#L7512
18:45 appgurueu I basically only see number and item as options
18:45 appgurueu But number is already used for colors
18:46 ccCam joined #minetest
18:46 appgurueu Krock, how about changing it in the API only? Or should I send an unneeded field with a proper name?
18:47 sfan5 the fact that "item" is handeled specially in c_content.cpp for waypoints if also bad
18:47 sfan5 is*
18:47 appgurueu Could you elaborate?
18:47 sfan5 if (elem->type == HUD_ELEM_WAYPOINT) [do something] else [do something slightly different]
18:47 appgurueu Yeah
18:47 appgurueu That is because of backwards compatibility
18:48 * Krock gives the microphone to sfan5. No motivation to discuss this sort of things rn
18:48 sfan5 why compatibility? you are just reading the value differently
18:48 appgurueu Yes
18:48 sfan5 with a default of -1 and you add 1
18:48 appgurueu If it is explicitly set, it has a different meaning
18:48 sfan5 while normaly item is read as -1 if not set
18:48 appgurueu Precisely, I golfed it a bit
18:49 appgurueu No, the default is 0
18:49 sfan5 yeah sorry I meant that
18:49 appgurueu Yeah
18:49 sfan5 point is, why can't you leave it like that and then check == -1 on the client side?
18:49 appgurueu And item = 0 means default precision
18:49 appgurueu But if a modder explicitly sets item = 0 they actually intend hide the distance
18:49 appgurueu That's what this thing accounts for
18:49 appgurueu * to hide
18:50 sfan5 and why doesn't that work when the default is -1?
18:50 appgurueu Because it'll set the default to -1 + 1 = 0 if it's not set
18:51 appgurueu Probably I should explain a bit more
18:51 appgurueu I implemented it as follows:
18:51 sfan5 I have read your implementation
18:51 appgurueu precision = item - 1
18:51 appgurueu basically
18:51 sfan5 but why can't the client fall back to precision = 10 if it sees item == -1
18:52 appgurueu because I intended to keep backwards compat
18:52 sfan5 that's perfectly compatible
18:52 appgurueu well, item = -1 is impossible
18:52 appgurueu item is u32
18:53 sfan5 oh hmm I get it now
18:54 appgurueu k
18:54 appgurueu so... should I change it in the API to "precision" ? Should I introduce a new field?
18:54 sfan5 I don't think reusing item internally is bad, but on the Lua side it should definitely be called "precision"
18:55 appgurueu Alright
18:57 Electro_Cloud anyone know what the best way to add IRC to a minetest server>
18:57 Electro_Cloud *?
18:57 sfan5 !mod irc
18:57 MinetestBot sfan5: Internet Relay Chat [irc] by kaeza - https://forum.minetest.net/viewtopic.php?t=3905
18:57 sfan5 that one, probably
18:57 Electro_Cloud nice thanks
19:00 tomraceror joined #minetest
19:03 appgurueu Electro_Cloud: You could also consider Advanced Chat - https://github.com/appgurueu/adv_chat
19:03 appgurueu Anyways, renamed it to precision, improved the docs (regarding my PR)
19:07 Electro_Cloud nice irc and discord
19:09 Electro_Cloud looks like it might take a little while to get setup the first time... does it require me to set up a port forward to my server?
19:09 Electro_Cloud My server is currently not available to the public, but would that make it not work>
19:14 sfan5 the IRC thing? not that I know of
19:15 MinetestBot [git] Jordach -> minetest/minetest: set_sky improvements, set_sun, set_moon and set_stars 946c03c https://git.io/JvV7o (2020-03-05T19:12:19Z)
19:17 Electro_Cloud ok cool
19:18 Electro_Cloud MinetestBot ?
19:18 Electro_Cloud is that for a future game update? Looks neat
19:19 sfan5 it is
19:21 Electro_Cloud =D
19:21 appgurueu it's awesome
19:21 Jordach 👀
19:22 Electro_Cloud imagine getting ray tracing in minetest
19:30 Electro_Cloud joined #minetest
19:32 Extex Krock with you currently working with waypoints what do you think of the plausibility of https://github.com/minetest/minetest/issues/9447
19:36 Electro_Cloud Very nice addition
19:36 appguru15 joined #minetest
19:40 DusXMT I have to say, at first, I found the lack of mobs (well, there are mods for them, but they all seem kinda glitchy to me, perhaps my laptop is just too slow for them) kinda disappointing, but now I've kinda grown to like how calm the game is :)  It definitely feels far more sandboxy than the game that shall not be mentioned
19:40 erlehmann joined #minetest
19:40 DusXMT Plus, some of the landscapes are just beautiful
19:42 DusXMT I kinda wonder if there is a mod similar to computercraft / opencomputers available to Minetest, I remember enjoying those :)
19:43 appgurueu ?
19:43 appgurueu mobs are inefficient right now
19:44 appgurueu I already have ideas on how to fix it
19:44 appgurueu There have already been attempts
19:44 appgurueu (not by me)
19:45 appgurueu And regarding opencomputers, as MT uses Lua by default, making Lua programmable stuff is quite easy.
19:45 sfan5 (that's not quite the same)
19:45 DusXMT Honestly, after getting back into the game a few days ago, I don't really miss mobs all that much
19:45 appgurueu There are some mods adding luacontrollers and the like (thinking of Mesecons), but I don't have a good overview right now
19:45 sfan5 or rather, doesn't really answer the question
19:46 appgurueu so, I renamed it to precision and improved the docs
19:46 appgurueu would you approve my PR?
19:46 sfan5 when I get another look at it
19:47 DusXMT Yeah, I guess LUA controllers from mesecons might be useful for automation, but I kinda liked how in Computercraft the computers were pretty general purpose, and you could even hook them up to screens... but I guess you might make your own indicator screen using a set of illuminator blocks
19:47 DusXMT with lua controllers
19:48 appgurueu sfan5: saw your review, will address, and probably also cover extex's use case
19:48 sfan5 don't mix image waypoints into this PR
19:49 DusXMT Heh, this made me remember Eloraam's RedPower mod, she had a computer as well in it, running an actual emulated CPU (the 6502 iirc, with forth as the default command interpreter, but you could write your own)... I wonder how hard would it be to make a similar computer in Minetest (but eg. with a Z80 instead, since that's what I'm more familiar with)

22:02 appgurueu Extex ?
22:02 appgurueu I've thought about your proposal (waypoint images)
22:03 appgurueu It's quite doable (1h effort I estimate)
22:03 appgurueu (or probably less)
22:07 Extex Cool
22:20 Electro_Cloud anyone know how to easily make a block a ingot instead?
22:20 Extex register_alias?
22:20 Electro_Cloud Like when it is done cooking is there a little code snip i can add
22:20 Electro_Cloud yeah
22:20 Extex Oh wait do you mean like completely remove them or cooking
22:21 Extex So you cook the block and you get 9 ingots?
22:21 Electro_Cloud I meant that right now i have a mod where i cook obsidian to get the block, and the block is only used for crafting so i was wanting to make it unplacable
22:22 Electro_Cloud is that possible?
22:22 Electro_Cloud Without going through a bunch of code like moreores
22:22 Extex Ooh so you want it to be just an item
22:22 Extex Not a placable obsidian
22:22 Electro_Cloud yes
22:23 Extex Either do node_placement_prediction = ""
22:23 Extex Or use a fake node image
22:23 Extex Like in carts
22:24 Extex Make it a craftitem and do this as inventory image
22:24 Extex minetest.inventorycube("carts_cart_top.png", "carts_cart_side.png", "carts_cart_side.png"),
22:24 Extex But I wouldn't suggest doing that
22:24 Electro_Cloud why not?
22:25 Extex Becuase it's just an image not a 3d model
22:25 Extex The wielded image will look flat and bot 3d
22:25 Electro_Cloud aah ok
22:25 df458 joined #minetest
22:25 Extex So I would use node_placement_prediction = ""
22:25 Electro_Cloud is there any other short way?
22:26 Electro_Cloud oh ok
22:26 Extex Just register a node and add that
22:26 Electro_Cloud ok add it right under the description of the node
22:26 Extex Yup
22:27 Electro_Cloud awesome, do i need anything inbetween the ""
22:27 Extex No
22:29 Extex That should work iirc
22:29 Electro_Cloud ok... ill let you know how it goes... im experiencing some difficulties with a recent change and when i opened the game and loaded the mod it showed them all as unknown blocks
22:29 galaxie joined #minetest
22:29 Extex Oke
22:32 Electro_Cloud hmm dosnt seem to be keeping me from placing it
22:32 galaxie joined #minetest
22:35 erlehmann joined #minetest
22:37 Electro_Cloud any idea why its not working?
22:37 sfan5 node_placement_prediction = "" just means it won't immediately disappear when you dig it
22:37 sfan5 its use sis somewhat specialized
22:37 sfan5 use is*
22:38 Electro_Cloud :O
22:38 Electro_Cloud oh ok
22:38 Electro_Cloud any suggestion to do what im looking for?
22:38 sfan5 on_place maybe
22:38 sfan5 in any case the documentation should definitely have an answer
22:39 Electro_Cloud just put on_place after the register
22:39 sfan5 oh I said " disappear when you dig it" above, I meant " appear when you place it"
22:48 Electro_Cloud can you leave a link to the minetest documentation
22:49 tomraceror joined #minetest
22:49 sfan5 !api
22:49 MinetestBot Someone thinks you should read the API docs, please go to: https://github.com/minetest/minetest/blob/master/doc/lua_api.txt
22:49 Electro_Cloud or is it the API documentation
