The source code of SimplyVanish can be found at GitHub:
For quick reference:
- The basic API can be found in the SimplyVanish plugin class (static API).
- The api package contains events and hooks that can be registered. The hooks will get adjusted or extended to allow for more distinct compatibility hooks (which players to show to which player).
- There may be other classes referenced and utility methods scattered around other packages, i will try to give an overview once requested.
