PAGE IS WIP AND UNDER CONSTRUCTION!

Modding is an exciting endeavor! Hopefully this page can serve as a quick-start on how you can do it to!

Requirements

- .NET Framework - https://dotnet.microsoft.com/en-us/download/dotnet-framework/net462


Quick Start

- Clone https://github.com/MaFi-Games/Captain-of-industry-modding into a directory (git clone https://github.com/MaFi-Games/Captain-of-industry-modding.git)

- Navigate to the directory and into src/ExampleMod

- Run dotnet build /p:LangVersion=10.0

We're using /p:LangVersion=10.0 for building mod, as otherwise it'll throw errors about too new language features being used. You can also edit ExampleMod.csproj to contain <LangVersion>10.0</LangVersion> in the first PropertyGroup.

Layouts / EntityLayoutParams / EntityLayoutParser

Layouts of structures such as machines or storages are based on a ASCII format passed as list of strings.

Example furnace:

   [2][2][2][3][3][3][3][3][2]>~Y
   [2][2][3][5][5][7][7][4][3]>'O
A~>[2][2][3][5][5][7][7][4][3]>'V
B~>[2][2][3][5][5][7][7][4][3]>'W
   [2][2][2][3][3][7][7][4][3]>'P
   [2][2][2][2][2][2][2][2][3]>@E


A~> and B~> are In Ports, they accept products.

>@E is exhaust

>~Y is slag exit

>' are Out Ports, they emit products

The > indicates the direction of the port. They can be one of the following:

- >

- <

- ^

- v

There is also a + port type, but meaning is unclear as of yet.

[1] - [9] ([n] essentially) are heigh units, they define the "hitbox" of the building, how many squares it takes up and where pipes/transports can and cannot pass.

Example Chemical Plant:

~E>[7][8][7][6][5][5][5]   
   [7][7][7][6][5][5][5]   
#D>[6][6][6][6][5][5][5]>X@
@A>[5][5][5][5][5][5][5]>Y#
@B>[5][5][5][5][5][5][5]   
@C>[5][5][5][5][5][5][5]   
   [5][5][5][5][5][5][5]   

Example Unit storage:

   [4][4][4][4][4]   
 # >4A[4][4][4]X4> # 
   [4][4][4][4][4]   
 # >4B[4][4][4]Y4> # 
   [4][4][4][4][4]   

(wrapped on the left and right with whitespace? Why?)

Example loose storage

"   [6][6][6][6][6]   ",
" ~ >6A[6][6][6]X6> ~ ",
"   [6][6][6][6][6]   ",
" ~ >6B[6][6][6]Y6> ~ ",
"   [6][6][6][6][6]   "

Example fluid storage:

"   [5][5][5][5][5]   ",
" @ >5A[5][5][5]X5> @ ",
"   [5][5][5][5][5]   ",
" @ >5B[5][5][5]Y5> @ ",
"   [5][5][5][5][5]   "

With this, we can establish that # is for transport belts, ~ is for loose storage belts and @ is for pipes. According to furnace, ' is for melted materials.

You can use the in-game console command print_entity_layout <string> to print the entity layout of a structure.

Notice: Some structures in the game use a "old" format of the layout, rather than the current format.
