Entity → ceramic.Systems (Class)

Manager for all System instances in the application.

Systems manages the lifecycle and update order of all systems in Ceramic. It ensures systems are updated in the correct order during both early and late update phases, handling automatic sorting and safe iteration.

Features:

  • Automatic sorting by update order
  • Safe iteration (handles systems added/removed during updates)
  • Two-phase update system (early and late updates)
  • System lookup by name
  • Automatic immediate callback flushing between systems

This class is created and managed by the App instance and typically doesn't need to be interacted with directly. Access it via app.systems.
