00:33 Niebieski Can we have better physics from Minetest ?
00:41 Hijiri like what
00:42 Niebieski Like better throwables.
00:43 Hijiri do you mean the throwables mod?
00:43 Hijiri I don't think there are worse throwables in the engine or default game
00:44 Hijiri I guess right now it's tough to have entities bounce off walls and floors
00:45 Niebieski I thought maybe Irrlicht would provide such an addition.
00:45 Hijiri maybe it could, I don't know
00:45 Hijiri I just use this channel to ask things

00:53 kaadmy irrlicht is only a graphics engine
00:53 kaadmy and does no physics at all
00:55 paramat you can have better physics if you code it :) we're very understaffed
00:56 Niebieski I would really love to do it. but I think the whole thing is above my skillset. xD

01:01 Niebieski I don't mind tiny tasks though. xD

08:26 sofar https://forum.minetest.net/v​iewtopic.php?f=9&t=13970 - record demo camera mod
08:43 sfan5 RealBadAngel: nice, does the line thickness change with distance from the camera?

13:25 RealBadAngel sfan5, no, it doesnt, im using normals of the surfaces to draw outlines
13:26 RealBadAngel when trying to do that with depth it looked like that, it was looking worse imho

17:03 RealBadAngel sfan5, http://i.imgur.com/V6g0AVu.png thx for the suggestion :)
17:04 RealBadAngel ive combined here both normals and inverted depth

19:12 Hijiri I've heard people say node timers are unreliable, is there any basis for that?
19:18 red-001 joined #minetest-dev
19:19 red-001 sofar is there any reason to use the square root of 20 for calculating tnt blast radius?
19:19 red-001 why not the sqaure root of 9 for example
19:20 red-001 that would keep the blast radius the same
20:02 H-H-H joined #minetest-dev
20:06 H-H-H joined #minetest-dev
20:08 sofar red-001: it was just an example
20:09 sofar my choice wasn't sqrt(20), but 0.05

21:29 paramat joined #minetest-dev
21:29 red-001 sofar how about not breaking nodes if intensity is say lower then 0.1 but still burning nodes and and calling on blast?
21:57 paramat hmmmm and all i'll merge #3590 later, is thoroughly reviewed
21:57 ShadowBot https://github.com/minetest/minetest/issues/3590 -- Add V5 caves to Valleys mapgen. by duane-r
22:12 hmmmm taking a look
22:40 sofar red-001: calling on_blast() equals destroying them
22:40 red-001 not always
22:41 sofar the mod decides if you call on_blast()
22:41 red-001 a mod can check if intensity is high enough to destroy it.
22:42 red-001 that could mean some blocks could be a lot easier to damage with tnt
22:43 sofar but then you're forcing mods to look at intensity
22:44 sofar that's an API change, again
22:44 red-001 what do you mean?
22:44 red-001 they can always not register it
22:45 sofar that's an incompatible change with mods that already use on_blast
22:46 red-001 well then we might as well keep using radius as the base unit
22:46 sofar huh, that change wouldn't change any existing API
22:47 red-001 i'm not sure any mods use on_blast
22:47 red-001 but I will check
22:47 sofar I've included it in my doors patches
22:48 red-001 ok I get your point
22:49 hmmmm paramat:  this line
22:49 hmmmm +mount = MYMIN(MYMAX(base - depth, (float) (water_level - min_bottom)), mount);
22:49 hmmmm could be replaced with a rangelim()
22:49 hmmmm that's what rangelim is for btw
22:49 paramat ah nice
22:50 hmmmm we don't allow variable length arrays in minetest
22:51 hmmmm when breaking a multiply operation onto multiple lines, please put the * operator on the previous line, so nobody confuses it for a dereference
22:51 paramat yes agreed
22:51 hmmmm I'll add these to the PR
22:52 paramat thanks
22:52 red-001 sofar shouldn't block destroy radius be sqrt(power/0.05) ?
22:54 red-001 that would give you the radius at which intensity is .05
22:54 sofar sec
22:55 paramat btw i realised we can move calculation of tunnel 3D noisemaps into generateCaves to avoid running those in empty chunks, will work on this
22:56 sofar indeed, futzed my math
22:56 sofar i = P / d^2  -> 0.05 = P / d^2 -> 0.05 / P = d ^2 -> d = sqrt(0.05/P)
22:56 sofar so not p/0.05 but 0.05 / P
22:57 sofar huh
22:57 sofar ok I can't do math with a headache
22:58 dfelinto joined #minetest-dev
23:05 red-001 nice firefox has a json viewer builtin
23:14 dfelinto ssh-impa
23:14 dfelinto ops :)
23:19 est31 hmmmm, VLA is a c++11 feature, right?
23:22 paramat thanks for all the line comments, as usual spotted many things i missed =}
23:31 est31 aha its C++14...
23:31 est31 still wondering why the buildbots didnt say a word
