07:59:13 <peter1138> Legs feeling it now.
07:59:49 <peter1138> Fellow rider pushing a bit too hard on the way home yesterday.

08:25:21 <peter1138> My own fault, I could just have fallen back...
08:44:01 *** supermop_work has quit IRC (Read error: Connection reset by peer)
09:00:11 <peter1138> Urgh, trying to view the plain-text part of an email but Outlook is... urgh.
10:54:28 <peter1138> Ooh, should I install the map update for my Garmin or will it never work again... :/
11:05:51 *** Smedles has joined #openttd
11:19:51 *** Montana has joined #openttd
11:20:43 <Eddi|zuHause> probably the latter.
11:29:47 *** agneli has quit IRC (Remote host closed the connection)
12:44:04 <peter1138> The new innovation for Garmin... solar power.
13:18:29 <Samu> some weird stuff happening with GetMaxHeight
13:30:11 <Samu> nevermind, i swaped tiles, it's me
13:48:25 <Samu> turns out the original pathfinder is bugged
13:48:42 <Samu> doesn't pick up all cases
13:49:48 *** WormnestAndroid has quit IRC (Remote host closed the connection)
13:50:56 <Samu> whats an alternative for pastebin, that doesn't spam me with ads
13:53:19 <LordAro> ...though looking at the archives, perhaps it should be turned off
13:54:52 <Samu> Your IP address is listed as a malicious IP.
14:02:39 <Samu> didn't even know it could be used for this
14:04:32 <Samu> so, how do I simplify that big if check
14:05:29 <Samu> the first if is equal to the second if
14:05:40 <Samu> but the check is still long
14:16:34 *** WormnestAndroid has joined #openttd
15:03:24 <Samu> i just realized i don't have to loop the entire path for a collision for every neighbour
15:31:35 <LordAro> that's a lot of bridges
15:32:01 <TrueBrain> imagine this with bridges over bridges
15:42:50 *** andythenorth has quit IRC (Quit: andythenorth)
15:52:21 <Samu> once I feel certain that the pathfinder is not giving me any issues, I will attempt dual rail code
15:52:28 *** Montana has quit IRC (Remote host closed the connection)
15:57:21 <nielsm> idea for dual rail: decide if you're building the left or right track first, and during pathfinding the first half (one way) give a penalty to tiles where the tile that would have the second rail on it is blocked or needs modification to be buildable
15:58:05 <nielsm> (the "decide which side you build first" doesn't have to be a decision the code makes, just an assumption written into the code that e.g. it's always building the right-hand track first)
16:00:01 *** lobster has quit IRC (Ping timeout: 480 seconds)
16:20:00 *** Wormnest has joined #openttd
16:21:17 *** andythenorth has joined #openttd
16:30:22 <Samu> my current idea is having "segments", two rail tracks next to each other in parallel, and then link to other segments to form a path
16:30:25 *** Smedles has joined #openttd
16:31:11 <Samu> but i found out there can be 20 different segment pieces
16:32:52 <Samu> my next problem to tackle is how am I advancing each tile, if i can have up to 4 tiles each segment
16:32:59 <Samu> advancing each neighbour
16:33:19 <Samu> they have to advance as a whole
16:33:32 *** andythenorth has quit IRC (Quit: andythenorth)
16:35:19 <Samu> and then there's the matter of bridges and tunnels, with are another type of segment, how am I advancing them
16:35:52 <Samu> but for starting, i can ignore bridge and tunnels for a while
16:37:59 <glx> are you trying to pathfind both tracks in the same PF run ? I think that can't work with A*
17:02:37 <Eddi|zuHause> well, you could transform the map to combine 2 adjacent tiles, and run the PF on that (that'll be a weird follow_track function with lots of cases)
17:03:23 <nielsm> do a very rough/low accuracy pathfinding first, choose a number of key points along that path, then use high quality/accurate pathfinding to attempt to connect those key points. first connect the right track to a key point, then connect the left track to the same key point
17:04:15 <nielsm> and when doing the right track between key points, prefer choosing tiles where there is space for a track on the left too
17:04:27 <nielsm> when doing the left track afterwards, prefer tiles that are next to the right track
17:08:17 *** HerzogDeXtEr has joined #openttd
17:08:23 <nielsm> a good distance between key points is probably 20-40 tiles

18:04:43 <TrueBrain> and how are we enjoying not receiving a ton of spam because of dependency updates? :P
18:05:22 <nielsm> I didn't know I missed it
18:07:12 <TrueBrain> the best changes ;)
18:50:05 <Samu> looks like I need more offsets
19:31:23 *** tokai|noir has joined #openttd
19:31:23 *** ChanServ sets mode: +v tokai|noir
19:38:20 *** tokai has quit IRC (Ping timeout: 480 seconds)
19:52:00 <Samu> question, how do i print a variable name?
19:53:44 <Samu> enum SegmentDir { SW_NE, etc... }, now I wanna print it to debug console
19:54:03 <Samu> AILog.Info(SegmentDir.SW_NE.tostring())?
19:54:23 <glx> you need to do it by hand I think
19:55:43 <Samu> guess i better get used to numbers
20:00:01 <nielsm> make an array of strings naming each of the values
20:43:46 *** nielsm has quit IRC (Ping timeout: 480 seconds)
20:57:54 *** HerzogDeXtEr has quit IRC (Read error: Connection reset by peer)
21:03:13 *** sla_ro|master has quit IRC ()
21:31:15 <Samu> i really need to use asserts more often
21:31:25 <Samu> too prone to fail somewhere
22:05:43 *** Samu has quit IRC (Quit: Leaving)
