09:29:46 <Joel> Is there a window event handler that will be triggered by changing the settings? I want to be able to set a member variable of the window when a setting changes, not OnPaint
09:36:14 <Eddi|zuHause> a setting can have a callback function when it changes
09:56:40 <Samu> how to know which is the most advanced railtype if they both have the same max speed and cost?
09:57:35 <peter1138> Pick the one that is compatible with the engines you want to use.
10:13:44 <peter1138> Okay, then it doesn't matter.
10:14:43 <Samu> i went with the cost factor , the higher, the better, keks, which may not always be the case
10:20:23 <Samu> problem is when everything is equal
10:20:30 <Samu> then i really have to random pick
10:27:33 <Samu> let's see now what it comes up for mail
10:37:59 <Samu> Driving Van Trailer + 4x Sliding Wall Van (Twin) on Advanced electric high-speed line construction
10:39:32 <Samu> guess going with the highest rail cost isn't always the best idea

12:51:06 <Samu> i don't know how to program this...
12:51:38 <Samu> i got 3 railtypes, each with 50, 70 and 90 max speed, then i have the train with 60 max speed
12:52:30 <Samu> i want to compute the railtype which is faster than the train but not the highest
12:52:44 <Samu> so, i want to get the railtype with 70 max speed
12:52:53 <Samu> don't know how to do this in code
12:55:23 <Samu> so, the one which is closest to the train speed, but never lower
12:56:15 <glx> rail list, valuate speed, filter
12:56:34 <Samu> and the other situation is, 3 railtypes with 30 and 50 max speed, with train 60 max speed
12:56:51 <Samu> in this case i want to get the fastest possible, which is 50
12:58:06 <Samu> i said 3 railtypes, i meant 2
12:59:07 <Samu> and then there's the matter of ties
12:59:43 <Samu> 3 railtypes, each with 60 60, i want to get both
13:00:37 <glx> they might have different costs
13:04:51 <Samu> i can only get a list of the fastest
13:09:32 <glx> I'd get an AIRailTypeList, valuated (and sorted) with AIRail.GetMaxSpeed, then you store the fastest railtype, then you remove items slower than the train
13:10:03 <glx> if the list is empty you use the stored value, else the slowest in the list
13:13:05 <glx> descending sort for unfiltered speed, so Begin() is the fastest, ascending sort for filtered so Begin is the slowest
13:35:15 <andythenorth> augment / replace train prop 25 with a dword, and add a var to read it?
13:35:31 <andythenorth> maybe ignoring the slightly odd var 42 OR thing
13:37:17 <andythenorth> it's such a classic :)
13:43:58 <Samu> thanks, I think I did it, let me test
13:45:12 <glx> of course before valuation with speed, you valuate with can run/has power and keep only what the train can use
13:46:39 <Samu> nop, i failed somewhere, the final list became empty :(
13:46:50 *** Joel__ has quit IRC (Ping timeout: 480 seconds)
13:54:32 <Samu> for some reason, the 2 temporary lists became both empty?
13:55:41 <glx> hmm you had list1 then did list2=list1 before filtering ?
13:56:05 <Samu> or 4 if i count the original one
13:56:16 <glx> IIRC lists are not copied when assigned to a variable
13:57:18 *** WormnestAndroid has quit IRC (Remote host closed the connection)
13:57:59 <Samu> list 1-> railtypes, it's an array
13:58:16 <Samu> list 2-> railtypes_list, it's an AIList
13:58:36 <Samu> list 3-> railtypes_below_train_speed, it's an AIList
13:58:51 <Samu> list 4-> best_railtypes, it's an array
13:59:03 <glx> you didn't valuate, so all values are 0
13:59:43 <Samu> i added the value railtypes_list.AddItem(railtype, railtype_max_speed);
14:00:13 <Samu> cant use valuate because some railtypes have 0 in it
14:00:16 <glx> ah right the values should be right
14:01:55 <glx> railtypes_below_train_speed.KeepBelowValue(train_max_speed); <-- don't you want the opposite ?
14:02:38 <glx> a rail speed limit higher than train speed limit
14:03:15 <Samu> ah, i think i found the problem
14:04:01 <Samu> railtypes_below_train_speed.KeepValue(railtypes_below_train_speed.GetValue(railtypes_below_train_speed.Begin()));
14:04:01 <andythenorth> dword per train vehicle then? :P
14:04:07 <andythenorth> breaks everything?
14:08:53 *** joel has quit IRC (Remote host closed the connection)
14:09:12 <Samu> it picked Zeus (Electric), with Suburban Coach (Large) on Dual-power accelerated main line construction
14:09:37 <Samu> rail line max speed is 180 km/h
14:10:14 <Samu> zeus electric is 159 km/h
14:10:38 <glx> would still be faster to use valuate, you can use a custom valuator
14:10:53 <Samu> suburban coach theres' 140 and 159 km/h
14:11:05 <Samu> so i assume it's the 159 km/h
14:12:22 <Samu> guess it got it right, the previous railtype speed is 130 km/h
14:17:41 *** joel has quit IRC (Ping timeout: 480 seconds)
14:18:21 <Samu> i'm against valuators, they cause spikes
14:18:42 <Samu> openttd becomes a stutterfest with them
14:21:23 *** WormnestAndroid has joined #openttd
14:28:33 <Samu> hmm there's no way to know if an engine is dual-headed
14:29:12 <Samu> can't do a precise measure of air drag
14:29:38 <Samu> it counts number of parts, and multihead engines are 2 parts in the equation
14:29:41 <andythenorth> air drag is silly

14:51:32 *** joel has quit IRC (Ping timeout: 480 seconds)
15:01:16 <glx> joel: yeah some part of the code are "hidden"
15:01:45 <glx> (not really, but settings is part of generated code)
15:02:19 <Joel__> Yeah I found out about setting callbacks, but couldn't figure out where to find it. Seems obvious in hindsight. Thanks for all the help so far, I really appreciate it
15:03:32 <LordAro> We appreciate you sticking with it :)
15:03:40 <LordAro> and all our unreasonable demands
15:10:40 <glx> github mobile app is weird, it correctly says 6 files changed, but if I click to see the diff, it also includes unrelated modified lang files from previous WT commit

17:46:52 <Samu> i finally integrated that whole advance distance from openttd into the script
17:47:03 <Samu> well, parts of, i assumed a lot of things
17:50:30 <Samu> from iron horse, it picked Hector (Electric) with 5 Railcar Trailers
17:51:20 <Samu> i assumed in code that train are going uphill the entire time
17:51:30 <Samu> maybe that's affecting the results

20:00:38 <Samu> woah, iron horse has some wagons with the exact same running cost, capacity and weight
20:00:49 <Samu> only differenciator is price
20:01:12 *** Mapminik has joined #openttd
20:02:08 <Samu> guess i need to take price into account in the formula, lol

21:42:08 <Samu> tables behave quite random
21:42:26 <Samu> i never get the same ordering
21:45:28 <Samu> it feels like I'm doing something wrong
21:47:26 <Samu> look at this piece of code
21:50:50 <Samu> because I'm using engineWagonPairs is a table
