The UseContentPipeline property on files controls whether a file is loaded using the content pipeline. By default files do not use the content pipeline - they load "from file".
Files which are added to FlatRedBall (such as .achx or .png) are considered "raw" files. These are files which generally use a standard file format which can be edited in a variety of applications. For example, .png files can be opened in any image editing software. The .achx file format is a simple XML file which can be opened in the AnimationEditor and also in any text editor.
Content pipeline files are "processed" when the program builds to create .xnb files. These files can be smaller, load faster, or use fewer resources. There is also a small security benefit to using the .xnb file format. Therefore you may want to use the content pipeline on your files prior to shipping your game.
Note that some files, such as .wav, must use the content pipeline if you are targeting MonoGame, so you may not have a choice.
If .xnb files are smaller, faster, and safer you may wonder why FlatRedBall offers a from-file option...and why FlatRedBall defaults to from-file.
The first reason is build time. By default files which are built as from-file do not have to built when the game is built - they are simply copied to the output directory. This process is much faster than using the content pipeline. Another reason is not all files support a content pipeline option. For example, Gum and Tiled plugins produce files which are loaded "raw" and currently do not support using the content pipeline.
The recommended approach is to use from-file loading whenever possible throughout development, and switch to using the content pipeline near the end of development for file formats which support it and if you need it.
To switch to the content pipeline:
Select a file in your project
Change the "UseContentPipeline" property to True
Your game will now load this file from content pipeline.
Note: Not all file formats support using the content pipeline. Also, not all platforms support the content pipeline.
Many files (like .achx files) depend on other files (like .png files). When you switch a file to use the content pipeline, the name of the file changes too. A file which used to be called "MyFile.png" (with extension) may get loaded as "MyFile" (no extension), and this impacts the name. Fortunately, FlatRedBall automatically handles this for you by generating a list of aliases. In other words, you can set your PNG's UseContentPipeline to true and everything should continue to work just like it did before.
