E2150 - Modding Overview

From InsideEARTH

To modify Earth 2150, you first need to understand the key components of the game and the limitations that are currently enforced upon the community due to the lack of available game source code.


The core components are as follows:

Engine

  • The Engine is fully contained within the game executable, for which the Source Code was lost.

Game Parameters

  • The core configuration of the game (outside of the engine) is done in the parameters file.
  • This file contains all information on definitions, buildings, units, weapons, and much more.
  • The parameters (or "par" file for short) is named aptly "Earth2150.par".

Programming Language

  • EarthC (or MoonC) is the main programming language for the game.
  • This is used to create Campaigns, Gametypes, Unit & AI Scripts.
  • Full guides for this can be found here & here.

Tools

  • SDK Tools
  • Community Tools
    • In this repository, you will find a combination of community developed tools to assist with the extraction, editing and re-packaging of the required game files.
