03:08 hmmmm https://github.com/minetest/minetest/commit/939397dd6e9cf26358b7e7f07aa58b72b175691f
03:09 hmmmm PilzAdam, it would be nice if we could get a different texture for grass that is placed randomly on the map that's shorter perhaps
03:10 ecube_ joined #minetest-dev
03:10 VanessaE hmmmm: junglegrass mod has three additional sizes
03:10 VanessaE http://forum.minetest.net/viewtopic.php?id=3898
03:10 ecube joined #minetest-dev
03:10 VanessaE feel free to use those.
03:10 hmmmm i'm not getting involved with minetest_game...
03:10 VanessaE so just grab the texture files from the mod?
03:11 hmmmm well i won't
03:11 hmmmm besides, i have stuff to do...
03:11 VanessaE ok
03:11 VanessaE oh, I misread that anyway

16:40 Calinou no
16:40 Calinou flickering in jungle grass? never saw it
16:40 Calinou quit playing with 8 bit z-buffer :P
16:42 rubenwardy joined #minetest-dev
16:53 troller http://benchmarksgame.alioth.debian.org/u32/benchmark.php?test=all&lang=lua&lang2=v8
17:20 rubenwardy joined #minetest-dev
17:39 troller js v8 faster than lua
17:41 troller and js language less crap than lua, but crap too
17:45 VanessaE the speed of a language is mostly dependent on its interpreter or compiler, and of course the skills of the coder.
17:45 VanessaE not so much on the language semantics or syntax
17:45 celeron55 what?
17:46 celeron55 lua is like js made right
17:47 celeron55 troller: why are you comparing a Javascript JIT to a Lua interpreter?
17:47 celeron55 stop being biased and compare v8 to luajit
17:52 celeron55 luajit will beat v8 almost always, by varying factors in the range 2...10
17:52 troller googled: luajit slower than v8, but possible to tweak via collectgarbage('setpause', 2000)
17:52 celeron55 lol, so what's the source for that?
17:53 troller http://habrahabr.ru/post/113250/ - but its russian
17:53 celeron55 here's some possibly quite unbiased benchmark (it's aim is to compare an another language to luajit and v8 and others) http://factor-language.blogspot.fi/2010/05/comparing-factors-performance-against.html
17:54 troller v8 3 years ago was slover
17:54 troller slower
18:02 proller__ joined #minetest-dev
18:20 rubenwardy how to convert wchar_t* or core::stringw to int?
18:20 rubenwardy CMainMenu.cpp:59:39: error: cast from ‘const wchar_t*’ to ‘int’ loses precision [-fpermissive]
18:29 ShadowNinja use long int?
18:30 VanessaE celeron55: is there any particular reason why the python mapper is still supplied with Minetest rather than the C++ one done by mireq?
18:30 VanessaE (https://github.com/mireq/minetest-mapper-cpp.git - needs a one-line tweak, see #minetest)
18:31 PilzAdam because the python mapper runs out of the box and the c++ one has extra dependencies?
18:31 VanessaE meh, not much of a good reason to supply a script that's ~50 times slower
18:57 rubenwardy yay! my first segfault!
18:58 Taoki joined #minetest-dev
19:02 Exio lol rubenwardy
19:03 rubenwardy outIP = new core::stringw(ipEditBox->getText());
19:03 rubenwardy outServer=(*outIP=="");
19:03 rubenwardy it works when outIP is "", but not when it has values
19:04 rubenwardy if values, then it segfaults on outServer
19:17 rubenwardy fixed it
19:22 rubenwardy for some reason printf("Connecting to server %s",outIP.c_str()); returns just the first letter
19:22 Taoki joined #minetest-dev
19:29 thexyz VanessaE: i guess this is because python mapper is easier to update/maintain
19:30 thexyz rubenwardy: why do you want to printf?
19:30 rubenwardy debuging
19:31 ShadowNinja errorstream << "Connecting to server " << outIP.c_str();
19:31 thexyz rubenwardy: you either have to %ls or (better?) std::cerr << "Connecting to server " << outIP
19:31 thexyz or that
19:31 thexyz not c_str() though
19:32 thexyz wait, wtf
19:32 thexyz why do we use core::stringw?
19:33 thexyz in some places, and std::wstring in other
19:33 rubenwardy it is not minetest
19:33 thexyz oh
19:33 thexyz so, i think you should change %s to %ls
19:33 thexyz as your string consists of wchars, not chars
19:34 thexyz also, if it's not minetest related, why do you ask in #*minetest*-dev?
19:34 rubenwardy because ##c++ and #irrlicht might as well be talking in code
19:35 thexyz ?

20:30 hmmmm PilzAdam, no, just add a normal grass texture and place that instead of jungle grass
20:31 hmmmm i'm gonna be pretty busy the next two days
20:31 celeron55 joined #minetest-dev
20:33 PilzAdam VanessaE, is it okay if I take plantslib's junglegrass_short.png as grass texture?
20:33 hmmmm wait no
20:33 hmmmm i don't just want a shorter version of the same thing
20:34 hmmmm i'm looking for something that's just as wide as the whole block, but shorter
20:34 VanessaE hmmmm: the shorter ones are hand-tweaked to look like short grass
20:34 hmmmm alright
20:34 VanessaE maybe regular grass should use 2x2 2d nodeboxes instead
20:34 VanessaE (like the way minecraft draws it)
20:34 PilzAdam hmmmm, what about rotating the plantlike drawtype only by 44° to prevent flickering if two nodes are next to each other?
20:35 PilzAdam (this is a problem for junglegrass wich has larger textures)
20:35 VanessaE that's hacky.
20:35 hmmmm dunno, i never noticed flickering
20:35 VanessaE it should be fixed by proper z-buffering if possible.
20:35 VanessaE but it's better than nothing
20:35 hmmmm yeah, but that's quite a lot of work if you aren't familiar with the drawing code
20:37 VanessaE hmmmm: the flickering he refers to is if you stack one junglegrass above another, the overlapping regions z-fight.
20:37 VanessaE (or side by side)
20:37 PilzAdam VanessaE, hmmmm is right, can you create a grass texture that goes fills the whole horizontal axis?
20:37 VanessaE PilzAdam: not right now, but in a little while maybe yeah
20:38 hmmmm hahaha https://dl.dropbox.com/u/100008207/screenshot_2097666821.jpg wtf
20:39 hmmmm i guess that happened on the edge with content_ignore, so it got placed
20:39 hmmmm and then it happened to be air
20:39 hmmmm definitely not easy to fix
20:40 PilzAdam VanessaE, not only when stacking junglegrass (you cant do this because its an attached_node), but also when 2 junglegrass nodes are diagonal placed
20:41 RealBadAngel hmmm, looks like ancient ruins ;)
20:42 VanessaE oh yes, I've seen that happen before too
20:42 PilzAdam VanessaE, also different textures (maybe 3 to 5) would be nice too
20:43 VanessaE I'll see what I can come up with
21:00 VanessaE PilzAdam:  http://digitalaudioconcepts.com/vanessa/hobbies/minetest/images/grasses/
21:01 VanessaE a little color shifting would make some kind of weeds or dried-out grass possible too.
21:11 PilzAdam should I also add this in: https://github.com/minetest/minetest_game/pull/127 ?
21:18 VanessaE PilzAdam: are those textures adequate? ^^^
21:18 PilzAdam the green from dirt with grass would be better
21:19 VanessaE easily fixed.  hold
21:19 PilzAdam and can you zip them?
21:19 VanessaE sure.
21:22 PilzAdam VanessaE, also, whats the license?
21:22 VanessaE http://digitalaudioconcepts.com/vanessa/hobbies/minetest/grasses-1.zip
21:22 VanessaE WTFPL
21:23 PilzAdam and the nyancat textures?
21:23 VanessaE WTFPL also; both can be CC-By-SA 3.0 if you want, since that is the license of the rest of the default textures.
21:24 VanessaE (though nyan cat stuff has already long since been updated)
21:27 PilzAdam https://github.com/PilzAdam/minetest_game/commits/grass
21:28 VanessaE looks good to me
21:28 VanessaE guess I'll need to update my junglegrass mod ;-)
21:28 troller coredump when punching 1 of 10k nodes of floating gravel 8)
21:29 VanessaE troller: oh sure, give the poor engine a heart attack
21:29 PilzAdam okay, Ill just push it :-)
21:31 troller idea about sources: maybe use automatic formater like astyle or indent or... ?
21:48 hmmmm dunno
21:48 hmmmm it might cause problems
22:57 VanessaE hmmmm: https://github.com/minetest/minetest/commit/fc5d2074b99d22022d2bf8e693351274bc3f6d09
22:57 VanessaE this appears to be causing more problems than it was supposed to solve.
22:58 PilzAdam would unpack(timer.args or {}) solve them?
22:58 VanessaE it solves it for builtin/misc.lua but that's apparently not useful for third-party mods.  this breaks mesecons pretty badly - uberi and I have been testing it just now.
22:59 VanessaE [03-18 18:59] <Uberi> oh and also make sure to mention the fix: builtin/misc.lua:24 should be "table.insert(minetest.timers_to_add, {time=time, func=func, args=...})"
23:02 VanessaE or rather line 25/.
23:02 VanessaE 25.
23:02 VanessaE [03-18 19:02] <Uberi> and instead of ..., I meant to write {...}
23:02 VanessaE [03-18 19:03] <Uberi> so builtin/misc.lua:25 should be "table.insert(minetest.timers_to_add, {time=time, func=func, args={...}})"
23:03 PilzAdam VanessaE, do these 2 things solve all the problems?
23:03 VanessaE not sure yet, I'm about to test them
23:03 VanessaE (I'm chatting with uberi in private)
23:04 PilzAdam VanessaE, is this correct? https://github.com/PilzAdam/minetest_game/commit/d5c373e290024790cc5e9fb9afcf03ef987f13ef
23:04 Kray joined #minetest-dev
23:05 VanessaE PilzAdam: yes, I believe that's what I have locally
23:10 VanessaE PilzAdam: ok, uberi's above proposed fix to misc.lua seems to work.
23:11 VanessaE (the change at line 25)
23:13 PilzAdam https://github.com/PilzAdam/minetest/commit/1e2d9542fa849fbd8cc89233e4e76eb5f1ee7b55
23:14 VanessaE checking
23:14 VanessaE [03-18 19:14] <VanessaE> correct?
23:14 VanessaE [03-18 19:14] <Uberi> yep
23:14 VanessaE gold :-)
23:33 RealBadAngel ROTFL
23:33 RealBadAngel disabling trees in mapgen works ok
23:33 RealBadAngel but it doesnt disable APPLES :)
23:33 VanessaE haha
23:33 PilzAdam lol
23:34 RealBadAngel i can see apples floating in the air everywhere
23:34 PilzAdam ^ hmmmm
23:35 RealBadAngel funny bug :)
23:35 PilzAdam https://github.com/PilzAdam/minetest_game/commit/e475d1322be05cc0c092cf2b824361219f1b7e90
23:36 PilzAdam can someone test the growing speed?
23:38 VanessaE PilzAdam: someone once suggested to me that vertically-growing things should stop at random heights say +/- 2 nodes
23:38 VanessaE (it was a suggestion for plants_lib, but may also be warranted here)
23:38 PilzAdam meh
23:39 RealBadAngel http://i.imgur.com/Z9ufsMM.jpg
23:39 PilzAdam VanessaE, dont be too realistic here
23:39 VanessaE no worries
23:40 VanessaE I was just passing it alone
23:40 VanessaE I'l looking at the papyrus growing code..this won't work
23:40 VanessaE you're testing for neighbors of dirt and grass...but shouldn't neighbors be air?
23:40 VanessaE similary for cactus
23:40 VanessaE similarly*
23:40 VanessaE I don't see how the plant will actually be able to grow upwards
23:41 PilzAdam the abm runs for the bottom node
23:41 VanessaE hm, ok
23:41 VanessaE I see what you're doing now
23:41 PilzAdam this limits the abm alot
23:42 PilzAdam I have taken it from my farming mod and tweaked it a bit
23:42 PilzAdam the farming mod hasnt the height <4 in the while loop, so you can freeze servers by building high stacks of papyrus :-)
23:43 VanessaE eek
23:43 VanessaE well this code looks okay to me anyway
23:43 VanessaE (you better fix farming :D )
23:43 PilzAdam growing speed seems to be ok too
23:44 PilzAdam i had 9 cacit at start and now (after posting the commit here) I have 7 more
23:44 PilzAdam (about 10 min.)
23:47 VanessaE that sounds maybe a little fast.  Half that speed maybe?
23:48 PilzAdam now I have 9
23:49 PilzAdam I wouldnt make it that much slower
23:50 PilzAdam when you are really waiting for it, then its slow enough
23:50 PilzAdam also, you need very much papyrus to get a few bookshelfs
23:51 VanessaE yeah I know
23:51 VanessaE bookshelves should at least have some use given their cost
23:51 PilzAdam 3 (for paper) * 3 (for books) * 3 (for the bookshelfs) = 27
23:51 VanessaE like storing large messages or something
23:51 VanessaE good use of that multi-line formspec mayeb
23:51 PilzAdam enchanting ;-p
23:51 VanessaE maybe*
23:51 VanessaE nooOOOooooOOoOO
23:52 PilzAdam if you start with 9 papyrus you have to wait 30 mins. to get one bookshelf
23:53 VanessaE your growing code should indeed help that
23:53 PilzAdam and cacti arent used for anything, so who cares if they grow fast? :-)
23:54 VanessaE I use them to make green dye :)
