City influence and size

[XWaste]

Ok, this is what the manual says (p26)

quote: As a city grows in population, its area of influence will eventually spread out even further, as much as two more tiles in every direction for extremely large cities.

so this is meant to mean that the city influence will extend three tiles from the city yes?

but, also from the manual (p27)

quote: Also keep in mind that a city's area of influence can expand considerably over the span of time. Although they may start of small and remain so for hundreds of years, eventually cities may grow to control every terrain tile within a five-tile radius of the city centre!

this seems to suggest that it will extend five tiles from the city?!?

As I am too impatient to wait until I have played a couple of games through to find out which is the truth can some one else please help me so I can plan where to put my cities - how large an area of influence do they get

Just the first in a long line of queries I am sure to have.

your city's tile influence grows with it's pop size. it's eventual size depends on your borders (marked in blue...) if you have no other cities close enough to infringe on your borders, it should very large. your first increase should come at pop 8 or thereabouts.

[DarkOrder]

size 7= 2 tiles
size 19= 3 tiles
size 30something= 4 tiles

at around city size 60 the city takes up just about all of the national border.

Yeah, I've noticed the border doesn't change when the cities area of influence changes. So the border is four tiles away, and the city can grow to fill the border

So the manual isn't right in any place, the city influence max is four tiles, not three or five?

I think it's something like:
------545------------------------------------
-----54345-----------------------------------
----5432345---------------------------------- ---543212345--------------------------------- ---432101234--------------------------------- ---543212345--------------------------------- ----5432345---------------------------------- -----54345----------------------------------- ------545------------------------------------

Thats probably wrong i remember 5 as only affecting 3 tiles each corner but there's definetly 5 and 5 only affects the corners
this is ****ed up because of the posting system thing try to figure it out

OK, so the max radius is basically four, but because for some reason diagonals are counted as two not one you can claim that the influence can reach five tiles away.


so instead of
--111--
--101--

I guess the reasoning is that because the diagonal length is longer then the model should be

--212--
--101--

It's not that big a hassle in the game, now that I have been playing a bit and so have a better feel for the cities and their growth but its just one of those things that make learning the game more frustrating than fun, with a manual that is so bad. Why couldn't they just say the influence will reach a four tile radius if that is the case.

I played around a bit with the lines

BORDER_INT_RADIUS 4
BORDER_SQUARED_RADIUS 20

in ctp2_data\default\gamedata\const.txt

as well as the SquaredRadius setting in citysizeX.txt

This in order to test different city influence settings and discovered the following:

first off.. the border_int_radius seems to do nothing (at least not that affects gameplay, I could be wrong though, correct me if so)

The border_squared_radius is interesting, corresponding the SquaredRadius in the citysizeX.txt determines which squares belong to a city influence.

I found out the following:

---------------
---------------
-----JHGHJ-----
----IFEDEFI----
---JFCBABCFJ---
---HEB000BEH---
---GDA0x0ADG---
---HEB000BEH---
---JFCBABCFJ---
----IFEDEFI----
-----JHGHJ-----
---------------
---------------

Where x is the city.
The letters denote areas under city influence (including areas with lower letter).

Producing a little table:

SquaredRadius     Letter
0-3               0
4                 A
5-7               B
8                 C
9                 D
10-12             E
13-15             F
16                G
17                H
18-19             I
20-24             J

(Yes, I restarted the game MANY times )

You can enter larger numbers in the citysizeX.txt, but make sure the BORDER_SQUARED_RADIUS is at least as large as the largest citysize. Don't know if the game will crash but it's illogical

Btw, does anyone know why there are 6 citysize files containing the same data?

Anyway, I hope someone has any use for this!
