Package Contents

The package consists of four folders:

  1. Gizmos — contains icons for sound and music bank assets;
  2. Stem/Documentation — contains pdf file with manual and API reference, fully matches the content on the site;
  3. Stem/Samples — simple scenes that covers basic Stem features;

Stem source code is divided into five folders:

  1. API — public API classes which you will be working with most of the time;
  2. Persistent — public data classes, that are stored inside sound and music bank assets;
  3. Editor — internal editor-only classes (inspectors for sound and music banks, scene postprocessor), will be excluded during the build;
  4. Runtime — internal logic classes which Stem automatically creates on demand;
  5. Basic or Pro — contains specific features depending on Stem version.
