I made a rather careless complaint in the Pak 128 graphics section (http://forum.simutrans.com/index.php?topic=1544.msg17523#msg17523 (http://forum.simutrans.com/index.php?topic=1544.msg17523#msg17523)) regarding factory's missing P****enger/Mail level when it is located outside a city limit. I now ****ume that a factory must be located within a city limt to have P****enger/Mail level.
Few questions:
1) What is the extent of a city limit?
2) Is the city limit static (unchanging throughout the game) or is it dynamic (growing/expanding with the growth of the city)?
-- If dynamic, does it expand uniformly in all directions or directionally depending on the direction of development?
3) If the city limit expands, then will that incorporate a factory now in no-man's land when the city limit reaches that factory (thus factory gaining P****enger/Mail capability)?
4) If a city limit remains unchanged, then I guess that the only way to have the factory gain P****enger/Mail capability is to start a new city in the vicinity?
I've been playing for over 2 years now but only now trying a rather larger map. Thanks!
city limit determines area where city buildings are built.
there is another area limit based on city same as "city limit".
where factories, raw producers within it
are ****igned p****/mail level.
Above are of my knowledge. Please correct me if I'm wrong.
It depends on the distance between cityhall and factory.
So, it never change by city growth.
/* add workers to factory list */
void stadt_t::add_factory_arbeiterziel(fabrik_t* fab)
{
const koord k = fab->get_pos().get_2d() - pos;
// worker do not travel more than 50 tiles
if( (k.x*k.x) + (k.y*k.y) < 5000 ) {
IIRC, in very old versions, this distance was recalculated when cityhall was moved to different place. But in recent versions, I guess this recalculation never happen.
I tried a simple experiment with blank map (no cities, no factories) and placing a new city in middle of nowhere. (latest r2392+Pak128v535)
Using a road originating straight from the new City Hall as guide (to make counting easier) --
- a new factory placed 70 tiles from City Hall has no "Workers live in city " (no P****enger/Mail level).
- a new factory starting on 69th tile has Worker (and thus P****enger/Mail level). Of course factories within 69 tile radius will have P****enger/Mail level.
So the city limit for a factory to have P****enger/Mail activity is 69 tile radius. Factories outside city limit do function as Goods producer/consumer.
And the city limit boundary seems to be a circle with 69 tile radius from the City Hall.
Also the city limit does not seem to affect Tourist Attractions (curiosities), as P****enger/Mail level appears whether inside or outside city limit.
Now that we can build whatever factory anywhere (as public player), I guess new factory location enters into the strategy if you want p****enger traffic there.
The city limits vary, don't they, with the size of the cities? They can be seen on the minimap with "city limits" enabled.
The city limit is a rectangular boundary that is 2 or 3 tiles far from outmost city building at N/S/W/Eastward.
Also, I'd like city limits were visible in terrain. This could be useful too see how far the city will expand.
Perhaps they could be visible when grid view is turned on?
Or just toggleable like the station coverage.
Must be a rounding issue. Check in code is "distance < sqrt(5000)" which (for integers) is equivalent to "distance < 70".
So your findings say the code indeed works as shown a few messages above ;) But the comment in the code ("worker do not travel more than 50 tiles") does not match the actual calculation.
Ooops, yes indeed there is city limit indication on the mini-map! I should start looking at all the options on this game. ::)
Perhaps my use of "city limits" in my context is wrong. Maybe "city-factory boundary"?
My point was to find how far a factory can be from the City Hall in order to generate P****enger/Mail ("Workers live in Cityname").
I've tried again on blank map, new city and new factories one 69th tile away and another 70+ tiles away.
69th tile factory has P****enger/Mail and 70+ does not.
Running a bus from City Hall to both these factories, there is p****enger traffic between City Hall (with few surrounding houses) and 69th tile factory but not with 70+.
So at least on this simple experiment (no other cities/factories etc on map), workers do travel more than 50 tiles.
Perhaps with more houses (after city growth) and/or other factories, this result may change?
Comments in the source code suggest that "workers live in city name" is merely cosmetic, and has no impact on game play.
Not, only for these cities a connect make sense. All other cities will not sent workes here.
