Data-Driven Foliage

Foliage interaction is configured through:

  • UEDInteractionSettings::InteractableFoliage

Each array entry is a FEDFoliageInteractionData describing one UStaticMesh type.

Key fields​

CorrespondingStaticMesh​

The mesh used by the instanced component. This is the key used to find the configuration at runtime.

InteractableTag​

The tag used for filtering, priority, and events.

Focusing (FEDFoliageFocusInfo)​

Controls:

  • Trace method policy
  • Max distance to the player
  • Look-at percentage threshold
  • Optional center offset (relative to instance transform)

Interacting (FEDInteractionInfo)​

Controls:

  • Interaction method
  • Duration / hit points / button mash parameters
  • Cooldowns
  • Destruction and sound behavior

WidgetUIInfo (FEDWidgetInfo)​

Controls what the interaction widget shows for this mesh type.

Outline (FEDOutlineInfo)​

Controls whether outline is shown and which stencil index to use.

Respawn (FEDFoliageRespawnInfo)​

Controls whether removed instances should respawn and how long it takes.

HitPoints foliage​

When a foliage entry is configured as HitPoints, the system can replace an instance with a spawned actor (AEDFoliageToInteractableActor) to allow damage application and per-instance behavior.
