Map Script Guide
=================
I will keep this updated and will add more as I go. Everything I have included here was pulled from the official docs. The easiest way to do this is to focus on your foundation first by getting the cities placed first.
Custom maps and map scripts should be placed in CapLabs user map folder located in: c:/user/Documents/Maps. If your are using a Regular script with your city script you will need to place a copy of your map in :C:/gameinstalldirectory/MOD/yourmod/MAPS. Adding Regional Map=MapName under the Header of your script.
Coordinates (X: 19, Y: 9)
Direct Mapping: To get your cities coordinates you will need to start a new sandbox game using your custom map with just one city. Once the game loads up open the in-game map and simply click the spot where you want the city to be located and the coordinates will be at the top left corner of the window.

Technique: Your Screenshot/screen snip tool is going to be your best friend. I'm pretty sure that paper stuff still exists too but your prob gonna have to complete a quest or two for a pen, lol.
[ENVIRONMENT]
Number of Cities=
I had to match this number with the actual value from the new game settings window. If you get a popup saying something about a town array error this is prob why. It's the main cause of the rage state I went into that caused me to learn how to make these maps.
[CITIES]
City=
If you KNOW your city is in the game already then you only Need the city Name. Leaving out (X: 19, Y: 9) defaults to random placement. No clue what data it uses but you can still include custom data.
If you KNOW your city is not in the game then you will need all the city data info including (X: 19, Y: 9). The numbers I have below are just from the example scripts. They do work in game and are fine to use. I'm just now playing my first real world data map.
City=
Population=500000
Globe X=
Globe Y=
Real Wage Rate=55
Population Growth Rate=200
If you would like to play a more realistic game using real world data I would suggest using AI that way you can get as close as possible to create a fun, balanced experience. I phrased it like so... "Using these cities and their real populations as of today, could you help me determine a good Real wage rate and Growth Rate number that will make a good balanced map script for Capitalism Lab ver 12+." Wage and Growth do not need to be exact just close enough. I will list some examples below because they are way lower than the other examples.
City=Chicago
Population=2721000
Real Wage Rate=1.15 ($20.00)
Population Growth Rate=0.003 (much slower, does not effect difficulty)
Regional Map X=14 (If you use my midwest map XY from there)
Regional Map Y=6
Seaports are always optional
City=
Consumer Goods Seaports=
Industrial Goods Seaports=
If you have a specific map that you like playing on you can save the map seed for use in your script. To find your map seed open the in-game map and hover your mouse over a city from the list at the bottom.
City=

Re: Guide for Custom Map Script (deprecated)
This post is no longer necessary because I created a tool to do this instead.
