7格内是1级市政厅，塞维利亚到第8格了2级没问题
你那个巴塞罗那不是正常建的吧，7格距离内至少会显示1级市政厅

巴塞罗那是一分，政策送的移民走过去坐的，开了很多局，一分都是直辖

在之后的三分，四分，五分里，会出现直辖，一级，都不一定的，距离都是离首都6-8

function SetCityLevelbyDistance (player,city)
local WorldSizeLength = Map.GetGridSize()
local policyID = GameInfo.Policies["POLICY_DICTATORSHIP_PROLETARIAT"].ID
local DistanceLV1 = 7
print ("DistanceLV1:"..DistanceLV1)
local DistanceLV2 = WorldSizeLength / 8
if DistanceLV2 > 18 then
DistanceLV2 = 18
elseif DistanceLV2 < 14 then
DistanceLV2 = 14
end
print ("DistanceLV2:"..DistanceLV2)
local DistanceLV3 = WorldSizeLength / 5
if DistanceLV3 > 30 then
DistanceLV3 = 30
elseif DistanceLV3 < 26 then
DistanceLV3 = 26
end
print ("DistanceLV3:"..DistanceLV3)
local DistanceLV4 = WorldSizeLength / 3
if DistanceLV4 > 44 then
DistanceLV4 = 44
elseif DistanceLV4 < 36 then
DistanceLV4 = 36
end
print ("DistanceLV4:"..DistanceLV4)
if player:GetCivilizationType() == GameInfoTypes["CIVILIZATION_POLYNESIA"] then
print ("No Lv 4-5 cities!")
DistanceLV3 = 999
DistanceLV4 = 999
elseif player:GetCivilizationType() == GameInfoTypes["CIVILIZATION_ENGLAND"] then
print ("Lv1 up for all cities!")
DistanceLV1 = DistanceLV2
DistanceLV2 = DistanceLV3
DistanceLV3 = DistanceLV4
DistanceLV4 = 999
elseif player:HasPolicy(policyID) then

虽然不知道lz在说什么，但好像很厉害的样子

沿海就是直辖，内陆城就有市政厅
