Starting Spring Development

NOTE: Outlined below is information on assisting with the development of the Spring source itself. For information about developing a game (units, widgets, maps, etc.) see the Gamedev:Main page.

Even if you are developing a game, it is highly recommended that you get the engine source. Engine source + full text search: DO IT.


To start development, you will need:

  1. To read the Coding_Standards
  2. A good code manipulation program: Development_IDEs
  3. Compiling the source code

Learning C++

You will need to know C++ to modify or understand Spring's source code. If you are interested in learning C++, see Learning_CPP

However please note that badly designed code (code created by a C++ novice for example), even if working will likely not be included in the spring code. Spring is a large project, and therefore it is necessary to stay away from hack jobs and create general solutions to problems.

Source Code Documentation

The doxygen documentation can provide an overview about the source, directory structure and its dependencies. Unfortunately, there is no server running it, so you need to make them on your own, to do this, install doxygen and run "doxygen" in spring source directory (will take some time).

An explanation on how the code is executed in game can be found in the Spring Engine Code page.

Development Guidelines

Before starting to make modifications to the source, take a look at the development guidelines which outlines some important things to think about. To find something interesting to work on, look for todos in the forum. You can also check in the forums to see what others are doing. If you do edit the code, please add Doxygen style comments to the code, which will then enhance the source code documentation.

Keep track what others do

If you develop with others, you need to know what they do. You can browse the source at our github-page, and there is a commit newsfeed.

Buildbot and Stacktrace translator

A buildbot server is here available to automatically compile Spring, the default AIs and make the installer. It can also translate stacktraces directly from uploaded infolog.txt files.

How to get your code included

If you create something that you think should be included in the official source tree please create a pull request to the develop branch of the spring repository on

Make sure that your changes:

  1. Were successfully tested locally.
  2. Conform with the Coding Standards.
  3. Are spread over an appropriate amount of commits - Please refrain from combining many individual changes into a single commit and from including merge commits.
  4. Include an update to the changelog if it's a major change - this is not to save work for the devs, but mostly to provide a concise explanation of what the pull request changes.

Post in the development forum or drop in #sy after creating the pull request (or while coding it) to get feedback and eventually to have it included.

Spring Engine TODO list

If you want to code something, look into the New Developers Forum for TODOs. There is also a feature request forum, which may give you some ideas. Don't be overwhelmed by the sheer number of (silly) requests though!

Alternatively, you may just search the code for the famous comment tags, for example on linux: <pre<noinclude></noinclude>>grep -r "TODO" rts</pre<noinclude></noinclude>>

The Bugtracker contains a long todo-list as well.

There are also some project proposals.
