Standard and standlone modes - C7-Game/Prototype GitHub Wiki

OpenCiv3 comes in two flavors: standard mode and standalone mode.

Standard mode relies on a local installation of Civilization III for art assets. You may set up the installation directory of Civilization III either in the project UI when first running it, or by setting the CIV3_HOME environment variable.

Standalone mode provides custom assets and allows to run the project without relying on external files. If you are using one of the release builds of OpenCiv3, the custom assets will be packaged with it, so you would be able to run the game right away. If you are developing the game, you'll need to download the assets first.

The assets are hosted in a repository that is included in the main repository as a submodule. To initialize it and fetch the assets, run the following commands from the main repository root:

git submodule init
git submodule update
