01:35:33 *** Mahjong has joined #openttd
02:00:11 <spnda> When I want a certain function to run on game start and then sometimes get reexecuted when a game starts or finished in which file should this be done? In a game core file maybe?
02:11:06 <Eddi|zuHause> what kind of function?
02:11:59 <Eddi|zuHause> if it's commands, you might want to look at server scripts or admin port
02:12:52 <spnda> what's the admin port again
02:13:19 <Eddi|zuHause> an interface for external programs to issue commands
02:13:32 <Eddi|zuHause> and a few other things
02:14:56 <spnda> Well it's a function for discord rich presence
02:15:39 <glx> admin port seems to be a good candidate then
02:16:26 <spnda> That's what planetmakers suggestion was on the forums. But when doing C++ I'm unsure how that would all work
02:16:59 <Eddi|zuHause> admin port is basically like a network connection
02:17:00 <glx> admin port can be used with any language, it's just an interface
02:17:20 <Eddi|zuHause> there are existing admin port libraries in java and python, i think
02:17:36 <Eddi|zuHause> you could use those as a starting point
02:18:24 <glx> and a big advantage of using admin port is that you keep a vanilla server
02:19:07 <Eddi|zuHause> and it'll work for both vanilla and patchpacks, without complicated merging
02:19:16 <spnda> But doesn't this mean the user would need to launch a different program?
02:19:56 <glx> admin port is on the server only
02:19:58 <Eddi|zuHause> you probably need to make a wrapper script that launches both your admin port library and the game at the same time
02:20:09 <Eddi|zuHause> and they would need to configure the game to open the admin port
02:20:21 <Eddi|zuHause> not sure if that's even supported in single player
02:24:03 <Eddi|zuHause> hm... my steam cart is alredy 30€ and i've made barely a dent in my wishlist :(
02:36:59 *** Wormnest has joined #openttd
02:37:17 <spnda> I just added the Discord stuff right into the source code. Works perfectly fine.
02:37:47 <glx> Eddi|zuHause: and how is the list of never started games ?
02:38:08 <Eddi|zuHause> glx: i'm fairly good at that... :)
02:41:14 <spnda> in game_core.cpp can I access the current company, if currently in a game?
02:41:49 <spnda> Or should I do this from a completely different file. (I know I probably should be doing it through the admin port but I want integration inside of the program)
02:43:13 <glx> if you want the actual player it's the local company
02:46:01 <spnda> Can I get the name of it?
02:47:57 <spnda> The name of the company itself, I mean.
02:48:41 <glx> it's a CompanyID so you can use company functions with it
02:53:16 <spnda> But how do I get a Company with a CompanyID?
02:53:48 <glx> Company::Get() should do it
02:54:15 <glx> than to get the name of the company you need to format the string
02:54:51 <glx> check usages of STR_COMPANY_NAME
02:56:41 <glx> you don't need to get the Company to get the name, CompanyID is enough
03:02:36 <tfgbd_> Use the resource editor. It's GUI now.
03:02:53 <tfgbd_> .rc .re files are not Editible Text
03:18:04 <spnda> Which function runs when a new game has just started?
03:18:14 <spnda> Or a game has been loaded
03:26:00 <glx> you can look for "game_start.scr" as this script is executed at start
03:33:48 <spnda> glx where are those scripts located? I can't find it
03:33:55 *** snail_UES_ has joined #openttd

11:46:04 <peter1138> Wait, surely you have more than one? :p
11:49:58 <Arveen> 🚲 have this one meanwhile
11:59:59 <Eddi|zuHause> have an empty box?
12:00:56 <nakki> it's two thousand nineteen and your irc client doesn't have emojis working?
12:01:28 <Eddi|zuHause> it's more to do with font selection than IRC client, i think
12:02:40 <nakki> sure, the whole stack matters
12:03:55 <peter1138> More importantly, does it work in OpenTTD? :D
12:04:53 <Eddi|zuHause> probably not out-of-the-box :p
12:05:31 <peter1138> Sadly OpenTTD substitutes the whole font when a glyph is missing, not just the missing glyph.
12:05:48 <peter1138> (Which is why font selection often doesn't work)
12:12:53 <reldred> You mean I can put emojis in my station names in openttd?
12:13:08 * reldred prepares to make Cursed Grfs
12:13:24 <Eddi|zuHause> you can put any unicode symbol in names
12:13:38 <Eddi|zuHause> but the font might not display it
12:13:57 <reldred> I'll start copying my github release notes made in the zalgo text generator into my grf descriptions.
12:14:35 <nakki> south hooverville station fhtagn!
12:15:18 <reldred> Sigh. Time to paint more pixels tonight I think.
12:15:33 <reldred> I fixed a ten year old bug in an unreleased station set last night, then released it.
12:15:57 <reldred> I mean be reasonable, we didn;'t have custom rail types back when I made that .grf
12:16:15 <reldred> but wow does it look nice with narrow guage :)

20:13:10 <andythenorth> now what shall I do? :)
20:13:41 <Eddi|zuHause> if in doubt, lunch?
20:16:28 <andythenorth> lunch happened at least twice today
20:50:15 <andythenorth> so...a map display to show industries with cargo transport below a % threshold? o_O
20:52:35 <frosch123> link industry directory to smallmap?
20:52:46 <frosch123> only show industries currently visible in the list?
20:52:55 <frosch123> then sort/filter the industry list
20:56:08 <nielsm> I wonder if a more flexible filtering UI would be useful in more places
20:56:28 <nielsm> vehicle lists, purchasing lists, industry lists
20:56:42 <frosch123> ideally there would be a list widget, which already provides text filters, column sorting and column filtering
20:57:05 <frosch123> currently all windows have to do that themself, and all do it differently
21:01:25 <nielsm> also for sorting it could be neat to have a way to select a sort by the ratio or difference or product of two parameters
21:04:04 <frosch123> freeorion uses stable sorting for all its lists, so you get most sort variants by clicking different rows in a sequence
21:04:29 <frosch123> but it does not resort automatically when numbers change
21:07:10 <frosch123> oh, also freeorion allows you to position and select visible columns
21:07:49 <frosch123> so, if your items have 20 attributes, you can pick which to display as columns
21:08:14 <frosch123> no spreadsheet formulas though :p
21:12:11 <spnda> Uh I just tried to get _cur_year from date_func.h and now in date_func.h and date_type.h some stuff is apparently undefined. That being: uint64, int32 and uint8. So uhm anyone know why this is?
21:12:42 <frosch123> always include stdafx first
21:12:56 <Eddi|zuHause> order of includes
21:13:29 <frosch123> stdafx first, safeguards last, that's the rule
21:14:15 <LordAro> (ideally, the headers should include the stuff they use, but...)
21:15:24 <frosch123> that should be the case for everything but those two
21:15:51 <spnda> huh ok. Also does _cur_year update automatically or would I have to check for it?
21:16:24 <frosch123> spnda: either there is a function returning the value, or there is a global variable with the value
21:16:41 <frosch123> but there is never a function to fill a global variable
21:17:11 <frosch123> otherwise that function could just return the value without needing a global
21:18:00 <Eddi|zuHause> ideally we would not have any global variables, but the code is very old in some places
21:18:11 <frosch123> (hmm though i guess there are exceptions with stuff from commands for the local company, like _refit_capacity)

21:35:08 <andythenorth> did someone make a grf with electricity as a cargo?

21:41:31 <nielsm> a better approach would probably be to just pretend there are underground transmission cables strewn about the map

21:41:51 <nielsm> and then have some kind of game global counting available power and demand power
21:43:37 <Eddi|zuHause> wires probably fall into the same category as pipes. they need a new transport type
21:43:40 <DorpsGek_II> [OpenTTD/OpenTTD] nielsmh commented on issue #7637: Midi notes are never released and sustained forever https://git.io/fj6YA
21:44:18 <LordAro> nielsm: like yoda you speak
21:46:12 <nielsm> I think it could be worth adding a new kind of variables in the game, accessible via newgrf and perhaps also GS, named globals
21:46:33 <nielsm> maybe named via the popular 4cc scheme
21:46:43 <Eddi|zuHause> nielsm: there is per-industry and per-town storage
21:47:01 <nielsm> yeah, here you want a truly global storage so all industries can sum up their total production
21:47:15 <nielsm> and towns can read the result
21:47:55 <DorpsGek_II> [OpenTTD/OpenTTD] mercuriete commented on issue #7637: Midi notes are never released and sustained forever https://git.io/fj6Oe
21:47:55 <Eddi|zuHause> global storage might overlap with GS scope
21:49:07 <DorpsGek_II> [OpenTTD/OpenTTD] nielsmh commented on issue #7637: Midi notes are never released and sustained forever https://git.io/fj6Of
21:50:14 <nielsm> Eddi|zuHause: it will, but it might also open a way for GS and GRF to cooperate
21:51:19 <Eddi|zuHause> ... which will open a dependency hell
21:52:08 <DorpsGek_II> [OpenTTD/OpenTTD] mercuriete commented on issue #7637: Midi notes are never released and sustained forever https://git.io/fj6OU
21:53:19 <spnda> This is probably the most wrong way I could have made this. I made the function to update Discord inside of the function that lets the toolbar show up.

21:54:19 <spnda> But hey this works just as expected... Just that the company name doesn't show up...
21:55:14 <Eddi|zuHause> you probably need to convert the name into a string
21:55:43 <spnda> I always get an assertion error if I do Company::Get(_local_company).name
21:55:54 <spnda> I think even with GetIfValid()
21:56:15 <andythenorth> nielsm: we devised some schema before for regions
21:56:25 <Eddi|zuHause> shouldn't that be ->name?
21:56:27 <andythenorth> which could handle power, if arbitrarily devised
21:56:47 <spnda> What's the difference between name, name_1 and name_2
21:57:01 <DorpsGek_II> [OpenTTD/OpenTTD] nielsmh commented on issue #7637: Midi notes are never released and sustained forever https://git.io/fj6OY
21:57:26 <spnda> Ah found it in the struct..
21:57:46 <spnda> Seems name_1 is the default name and name is when the user changed it. A bit complicated I feel
21:59:40 <spnda> yup it crashed because of that
22:01:26 <DorpsGek_II> [OpenTTD/OpenTTD] nielsmh commented on issue #7637: Midi notes are never released and sustained forever https://git.io/fj6On
22:04:47 <frosch123> spnda: you should not use either of them
22:04:58 <frosch123> instead you should use a string with {COMPANY}
22:05:27 <spnda> I don't want to create a string in the language files though.
22:05:29 <nielsm> there is probably a STR_JUST_COMPANY constant you can use
22:05:39 <nielsm> which is just the company name and nothing more
22:07:41 <nielsm> or STR_COMPANY_NAME_COMPANY_NUM :{COMPANY} {COMPANY_NUM}
22:08:03 <spnda> so how would I convert that to std::string?
22:09:53 <nielsm> that gets the raw format string, it doesn't format
22:10:26 <nielsm> char buffer[64]; std::string foo{GetString(buffer, STR_COMPANY_NAME, lastof(buffer))};
22:10:57 <nielsm> before that you also need: SetDParam(0, company_number);
22:11:15 <nielsm> (to indicate which company you want the name of)
22:12:17 <spnda> I'll try that. Thanks a lot
22:13:23 <nielsm> also no that won't work
22:13:36 <nielsm> since I didn't read what GetString returns
22:13:47 <nielsm> (it returns a pointer to the end of the formatted string, not the start)
22:14:20 <spnda> Just wanted to say... I got no output
22:14:34 <nielsm> SetDParam(0, company_num); char buffer[64]; GetString(buffer, STR_COMPANY_NAME, lastof(buffer)); std::string name(buffer);
22:15:21 <nielsm> it'd be nice if someone would change the string formatting to return std::string or something like that...
22:16:27 <spnda> Thanks a lot for that code. It's now showing up correctly as "Unnamed"
22:23:33 <andythenorth> 52 trains to draw
22:32:33 <Eddi|zuHause> why is going by train twice as expensive as going the same route by car?
22:33:26 <andythenorth> because safety cases
22:35:07 <spnda> how do I declare global variables again and use them in another file? I'm getting linker errors all the time because the variable is already defined
22:35:29 <nielsm> use the extern keyword
22:35:48 <nielsm> "extern int _foo;" declares that _foo is an int with storage defined somewhere else
22:36:24 <spnda> In all other files I do extern std::chrono::milliseconds _timestamp;. In the header file I just do std::chrono::milliseconds _timestamp
22:37:35 <spnda> everywhere else aswell or not?
22:37:38 <milek7> and in single translation unit declare storage
22:37:38 <nielsm> now you're defining storage in all cpp files that include the header
22:40:21 <DorpsGek_II> [OpenTTD/OpenTTD] nielsmh opened pull request #7638: Change: Limit in-editor warnings in VS 2019 https://git.io/fj63e
22:41:29 <spnda> Now I'm getting unresolved external symbol in my header file I think
22:42:02 <nielsm> did you decide on which cpp file owns the global?
22:42:29 <nielsm> you decide on one (arbitrarily, but probably something that would make sense to others) that define the global as not extern in that one
22:43:20 <spnda> No I did not. So do I just have to remove the extern symbol in one cpp file?
22:44:09 <nielsm> compare date_func.h and date.cpp
22:44:28 <nielsm> see how date_func.h declares _cur_year as extern, and then date.cpp declares it as not extern
22:44:43 <nielsm> that makes date.cpp "own" the global by defining its storage
22:45:33 <Eddi|zuHause> you put the extern in the header file, and the not-extern in any cpp file, no extern in the other cpp files
22:45:53 <Eddi|zuHause> the other cpp files just include the header
22:46:00 <Eddi|zuHause> which will include the extern
22:47:42 <spnda> Thanks guys. If anyone has Discord and are on the same guild as me. You can see my feed of what I am doing in OpenTTD now.
22:51:10 <Eddi|zuHause> "withe the purchase of this bundle you save 0,--€", thanks, steam.
