Linking Games to FlatRedBall Engine Source

Adding FlatRedBall Source to a Game Project using the FRB Editor

To add the FRB source to your project:

1. Make sure you have already cloned the FlatRedBall and Gum repositories. We recommend using Github for Desktop and cloning to the default location so that your game and FlatRedBall are sibling folder sin the same parent folder.

2. Open your project in the FlatRedBall Editor

3. Select the Project -> Link Game to FRB Source menu item

Game Project Location and FlatRedBall Source

The FlatRedBall Editor attempts to link FlatRedBall source regardless of the location of your projects relative to source. We strongly recommend keeping your project in the same directory (such as C drive) as FlatRedBall source. Otherwise, projects will be linked using absolute paths which makes your project far less portable. By using absolute paths others who clone your project must have the same exact folder structure as you do or the project will not build and run.

Furthermore, Github for Desktop always clones projects to the same directory: C:\YouserUerName\Owner\Documents\GitHub\YourProjectName

We recommend keeping these defaults for all repositories - your game and FlatRedBall. By using default locations others can clone the engine and game without needing ot make modifications to their defaults.
