00:00 Zeno` also in the gimp with a few brightness adjustments
00:00 Fixer Zeno`: https://i.imgur.com/VeCUIUZ.png
00:00 Zeno` yeah the problem in that screenshot is it's the same colour as the clouds
00:00 Zeno` so I thought it was a cloud lol
00:01 Zeno` it's still very hard to see with my calibrated monitor even now I know it's there
00:01 Fixer added "not a cloud" to issue
00:01 Zeno` but yeah I agree that it's a bug
00:01 Fixer my eagle astigmatic eye spotted it
00:02 Zeno` you should post a brightness adjusted image so people can actually see the thing! lol
00:02 Zeno` call it "CSI enhanced"
00:03 Zeno` Maybe it's a moon, VanessaE?
00:03 VanessaE heh
00:03 OldCoder joined #minetest-dev
00:04 Fixer Zeno`: NO
00:05 Zeno` it's a moon!
00:05 Zeno` or a deathstar, one of the two
00:05 Zeno` anyway the texture seems to be tinting clouds as well
00:05 Zeno` well something is making the clouds a stupid colour
00:06 Fixer gn, have fun with bugs
00:06 Zeno` I guess not a star wars person
00:10 paramat hehe
00:10 Zeno` does this demonstrate the issue more obviously: http://imgur.com/TUE3bzZ
00:10 Zeno` the texture is always visible
00:11 Zeno` :3
00:11 paramat top of texture above horizon
00:13 Zeno` paramat: I know... see my link
00:13 paramat i did, useful
00:13 Zeno` wicked_time_of_day lol
00:14 paramat hehe i like that
00:14 paramat must ask c55 what it means
00:14 Puka joined #minetest-dev
00:15 paramat afk for omnom
00:15 Zeno` I don't understand the logic of that function :3
00:16 Zeno` if sunlight is seen then draw stars?
00:23 rubenwardy joined #minetest-dev
00:31 Void7 joined #minetest-dev
00:35 Zeno` it's a very, very, very old bug
00:36 Zeno` present march 2012
00:37 Zeno` float a = easeCurve(MYMAX(0, MYMIN(1, a_)));
00:37 Zeno` I don't think that a_ can ever be < 0 and therefore a is never set to 0 as it should be (it's close to 0, but not 0)

01:39 jin_xi joined #minetest-dev
01:50 paramat ok i'll now make a 2nd attempt at cleaning up lua-api.txt, to avoid conflicts i will want to merge it in 2-3 hours
02:01 Zeno` hmm it only seems to happen if you set the time using /time
02:02 Zeno` after a day night cycle completes the bug doesn't show
02:10 Zeno` it's not a position though, paramat
02:12 paramat i was thinking the sunrise texture rises and then sets during either dawn or dusk
02:13 paramat i mean during dawn it goes up then back down behind the horizon
02:14 Zeno` hmm it does based on that value yeah
02:14 paramat y seems to be controlling vertical position
02:15 Miner_48er joined #minetest-dev
02:16 Zeno` graph -(1.0 - (x^3 * (x * 6*x - 15) + 10))) * 0.2
02:16 Zeno` oops
02:16 Zeno` meant to paste that into google heh
02:22 Puka_ joined #minetest-dev
02:33 paramat hi hmmmm here's the lua-api.txt cleanup of the worst aspects, plus 'Biome API'. i want to merge this within 2 hours before i sleep, to avoid conflicts, reviews welcome
02:41 Zeno` I'm not even sure it works properly for sunrise :3
02:41 Zeno` unless it's my time_speed messing things up
02:42 bugzapper joined #minetest-dev
02:42 Void7 joined #minetest-dev
02:42 Zeno` although it does work as expected for sunset
02:46 Zeno` which if you look at the graph of the ease curve makes sense
02:46 Zeno` it's different left and right of the y axis
02:47 paramat interesting
02:48 paramat btw zeno, please sometime could you review #4163 ? no devs have commented or reviewed yet
02:48 ShadowBot https://github.com/minetest/minetest/issues/4163 -- Sky: Darker, bluer sky and improved horizon haze at night by paramat
02:52 Zeno` hmmmm commented (said it was subjective)
02:52 Zeno` :)
02:52 Zeno` anyway I think the PR looks better
02:54 paramat no rush, you're busy with stuff
02:55 Zeno` I'm just confused
02:55 Zeno` I don't think sunrise works at all :/
02:57 Zeno` well it does, but in reverse to how it should
02:57 Zeno` the reason that using /time 0 (for example) shows the stuck "glow" is because of this other bug
02:57 Zeno` look to the west on a normal day cycle and you will see the sun doesn't set properly
02:58 Zeno` look to the east on a normal day cycle and you see it doesn't rise as expected
02:58 Zeno` (normal day cycle means just increase speed and watch without using /time to set the time)
02:59 Zeno` the rotating by -90 if wicked_time_of_day < 0.5 isn't exactly the right approach using that ease curve
02:59 Zeno` is not < 0.5 *
03:04 paramat ok will check this more tomorrow
03:04 Zeno` changing to float y = -(1.0 - a) * 0.255;  will fix the reported bug
03:04 Zeno` or even float y = -(1.0 - a) * 0.26; to make sure
03:04 Zeno` but it doesn't fix the sunrise not working in the first place (not like a real sunrise anyway)
03:04 Fritigern joined #minetest-dev
03:05 Zeno` the glow doesn't appear until after the sun is fully risen (in minetest currently)
03:05 Zeno` the glow should appear before the sun rises
03:11 Zeno` or at least follow the sun as it rises
03:16 Zeno` changed my mind... just do float y = -(1.0 - a) * 0.22 heheh
03:18 paramat ok i'll test that later
03:20 hmmmm paramat, sure, looks good
03:22 paramat thanks

03:27 paramat will merge in 20min
03:43 paramat merging 4196
03:44 VanessaE that was only 16 mins :P
03:45 hmmmm hey Zeno`, what do you think about getting rid of MapgenParams and other similar structs and replacing them with Settings?
03:46 hmmmm i'm still sorta conflicted
03:49 Zeno` yeah, not sure, but I'll think about it some
03:49 Zeno` right now I gotta run (appointment)
03:50 paramat merged
