Respawn & Replication

Foliage instance state needs to be consistent across clients. EDInteractionSystem handles this through the GameState component.

Replicating “removed instances”​

UEDInteractionGameStateComponent maintains a replicated fast array:

  • FEDRemovedFoliageInstanceList

Each item contains:

  • StaticMesh (mesh type)
  • Location (quantized)

Clients apply replication updates by finding a matching instanced component in the world and removing the instance.

Respawn​

If a foliage entry has Respawn.bShouldRespawn = true, the server can schedule respawn.

The server stores respawn queues per instanced component and periodically decrements countdowns.

When a respawn triggers:

  1. The “removed instance” entry is removed from the replicated list
  2. A multicast notifies clients to refresh focus state
  3. The instance is added back to the matching instanced component

Destruction effects and sounds​

Foliage entries can specify:

  • A destruction effect actor class (DestructionEffectClass)
  • An optional destruction sound
  • Whether effects/sounds should clone scale from the original instance

The GameState component spawns effects and multicasts sound playback.
