Might be your case too so check to see if you have a unit already on it that prevents you from loading more.

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

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

code:

---

------545------------------------------------
-----54345-----------------------------------
----5432345---------------------------------- 
---543212345--------------------------------- 
---432101234--------------------------------- 
---543212345--------------------------------- 
----5432345---------------------------------- 
-----54345----------------------------------- 
------545------------------------------------

When you post/reply to a message, there is a margin on the left of your text box. There you'll notice the link "Smilies Legend". It tells you how to do all the special smilies

where'd I hear that

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

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

--212--
--101--

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:

code:

---

---------------
---------------
-----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:

code:

---

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?
