05:59:00 *** ZexaronS has joined #openttd
06:01:26 <ZexaronS> tried openTTD for the first time, I probably saw this on some windows 3.1 PC or some similar game like this way back in the day in school
06:01:57 <ZexaronS> But here's some feedback, I thought of just going in without reading absolutely anything about it
06:02:15 <ZexaronS> I've been searching for 30 mins and I can't find how to make new train order
06:03:59 <ZexaronS> secondly, I hoped the popup windows would close down if i clicked the button again
06:04:31 <ZexaronS> this is just pure feedback from someone crashing in, hopefully not taken personally
06:05:06 <supermop_home> not many people on here at this hour
06:05:11 <ZexaronS> so I have no idea what is intentional or not
06:05:22 <supermop_home> not many would take it personally either
06:05:53 <supermop_home> for orders... there is a button on the train's window
06:05:58 <supermop_home> looks like an arrow
06:06:08 <supermop_home> opens the order UI
06:06:26 <supermop_home> order UI has plenty of its own problems
06:06:45 <supermop_home> but in there you can click 'go to' then click stations etc
06:07:24 <supermop_home> if you click the orders in the list you can then set things like 'load' or 'unload'
06:07:39 <supermop_home> holding down those buttons gives more options
06:07:52 <ZexaronS> oh, I mean "personally" it more of a "outsider" or someone from another community, I'm actually the old cat still even very young at the time, I was born into commander keen and dangerous dave so I'm not from the modernwarfare commuinty and I wouldn't want to force anything from the wild pop indutry into this program, just to clear that out
06:09:13 <supermop_home> openttd is a project of many people over 20 years, so lots of ideas have come that maybe don't work all that intuitively together
06:09:29 <supermop_home> so its a given that somethings are not ideal
06:09:38 <ZexaronS> this got my attention because I remember a train game, with lots of train tracks, and always wanted kept wondering, I rememebered it years later but I forgot to ask my friends about it at the time
06:10:13 <supermop_home> and usually insight of others is not frowned upon, just so long as you don't demand changes a certain way right now
06:10:33 <supermop_home> as things only get worked on when people have time to do it for free
06:10:51 <ZexaronS> it's one of those i didn't knew the name, we knew commander keen, but I didn't knew I was playing dangerous dave because it was a weird exe, probably ddav.exe or something hah
06:11:30 <ZexaronS> I'm not sure if the train game was this, but it's very similar, but I remember it in a texas-like desert theme
06:12:39 <ZexaronS> The year was something 2000-2001 ... everything was delayed here, it's now USA
06:12:48 <ZexaronS> so stuff that was 5 years out, was new here
06:19:39 <ZexaronS> I installed it a week ago gave it a try at the last min, yeah it's late, later
06:29:13 <ZexaronS> bah i was clicking on the factories with the goto thingy

15:56:30 <Samu> uhm... i'm scared of showing this to u
15:57:33 <Samu> how can I improve that :(
15:58:24 <Alberth> you have good reason to be afraid :p
15:58:48 <Alberth> how do you manage to make such code?
15:59:48 <Samu> that is the auto-terraform code for ship depots :(
15:59:48 <Alberth> anyway, look for duplicate pieces of code, move them to their own function, and call that function when you need to
16:00:27 <Alberth> lots of detailed cases eh?
16:01:08 <Alberth> if you look at the end-result, how many different results can you get?
16:02:04 <Alberth> eg if it is always flat, you basically have 1 end result
16:02:45 <Alberth> so another approach is to describe the end result, and then write code that modifies the terrain to that result
16:03:18 <Alberth> where "describe the end result" is a simple array of desired tile heights
16:05:06 <Alberth> instead of hard-coding all cases, you compute what must be done on each tile, by comparing reality with desired result
16:05:55 <Samu> it's always flat, but sometimes the height can differ
16:06:15 <Samu> flat with the height +1 or flat with the height + 0
16:06:51 <Alberth> where does the height + 1 (or + 0) depend on
16:07:50 <Samu> can't remember specifically, but I think I was counting the number of corners
16:10:16 <Samu> damn, i worked on this last year or so, i had posted some screenshots, gonna see if i can still find them
16:19:40 <Samu> who would have thought, I found a bug right away :(
16:22:03 <Alberth> it also would help if you comment what each block of code is doing
16:22:29 <Alberth> right now, you have to carefully read each line and decude what it aims to do
16:22:56 <Alberth> if you write that in text/comment above the lines, it's faster to read, and less error-prone
16:24:26 <Samu> if 4 corners were tileheight +1 and 2 tileheight 0, then the result would be flatten to the height of +1
16:24:58 <Samu> in case of a tie, I dunno, gotta read all those cases indeed
16:26:12 <Alberth> 6 corners? I'd hope a tile has 4
16:26:47 <Alberth> right this is just 2 tiles below the depot?
16:27:45 <Samu> tile 1 has 4 corner, tile 2 has 4 corners, but tile 1 and tile 2 share 2 of those corners
16:28:37 <Alberth> so what if you obtain highest corner height and lowest corner height, and then for each height in that range compute how much height difference exists for the 6 corners.
16:28:50 <Alberth> Then pick the height with the smallest height difference
16:29:44 <Alberth> ie compute the best solution instead of testing for all cases
16:43:11 <Samu> if (slope1 == ComplementSlope(slope2) && IsInclinedSlope(slope1)) {
16:43:33 <Samu> it only flattens one tile
16:44:04 <Samu> maybe it is what it should do, but it's not detecting how it should be done
16:44:23 <Samu> oh well, gonna try do this differently
16:45:12 <Samu> okay, so first thing to do is count corner heights?
16:52:25 <Alberth> I'd start with finding lowest and highest height
16:52:49 <Alberth> which can be different from each other by at most 2
16:55:17 <Alberth> hmm wait, how do you need terra-forming here? you build a depot on water, which is flat, aren't you?
16:55:47 <Samu> it flattens it, builds canals, then the lock

16:57:31 <Samu> i'm finally starting to see the light*
16:59:05 <Samu> I was working with only 4 heights
16:59:17 <Samu> wasn't it supposed to be 6? now i'm confused myself
16:59:45 <Alberth> a slope is not a corner
17:00:46 <Samu> Slope GetTileSlope(TileIndex tile, int *h)
17:02:05 <Samu> no wonder this was bugging
17:02:40 <Samu> z_slope2 is the same as z_middle_corner_n
17:03:32 <Alberth> height of a tile is not the same thing as height of a corner
17:03:51 <Alberth> since a tile has 4 corners, which may be at different heights
17:08:39 <Samu> z_slope2 is different than z_middle_corner_n?
17:08:44 <Samu> i'm even more confused now
17:11:10 <Alberth> why are you dragging slopes in?
17:12:02 <Samu> im following the code, and apparently I messed up
17:12:28 <Samu> tileslope height is not really the same as tileheight
17:13:09 <Samu> was trying to understand what to do
17:14:30 <Alberth> so start with 4 functions that computes height of the 4 corner of a tile
17:15:53 <Alberth> break your problem in smaller pieces, until the pieces are small enough to build, then build them, and compose them to the whole functionality

23:32:16 <supermop> so the first job offer i had seems to have evaporated, but i just got another offer
23:32:36 <supermop> unfortunately the compensation is worse than my current job
23:43:36 *** Progman has joined #openttd
23:55:24 <Samu> but i'm yet unable to do as Alberth suggested :(
23:56:33 <Samu> he tries to help me, and yet... i still can't figure it out
continue to next day ⏵
