Plugin API Roadmap (Quill) #344

#307 introduces a preliminary draft of Feather's plugin API, quill. This is tracking issue for features needed in the plugin API to achieve the goals laid out in our mid-term roadmap.

Foundational features:

• Plugin state struct
• Access to Copy components from the host
• Mutating Copy components from the host
• Defining, accessing, and mutating custom components
• Creating and removing entities
• Access to opaque, non-Copy components from the host
  • Name
  • Inventory
  • Window

Features needed for a hub plugin implemented with Quill:

• Support all vanilla entities in Feather: armor stands, mobs
• Particles
• Entities
• Custom GUIs for server selection
• Sending plugin messages (needed for BungeeCord server transfer)
• Potion effects
• Others?

Features needed for minigames implemented with Quill:

• Block access, ideally with bulk operation support ("fill this chunk section with the given block")
• Custom WorldSources defined in plugins for custom world loading/saving logic
• Others?

Miscallaneous:

• Plugin assets - stored in the plugin's tar file?
