FDungeonRandomActorParts Reference

FDungeonRandomActorParts is the container used when you want multiple actor candidates at the same spawn point and want them to appear by probability. It inherits from FDungeonActorPartsWithDirection, so it keeps direction and offset data while adding Frequency to control how often it appears.

Main usage

• Register shrine, treasure chest, or environmental-object variations that should appear only sometimes at the same location.
• Add them to random-actor arrays in generation settings so they are drawn during generation.

What the UPROPERTY means

• Frequency (float, EditAnywhere/BlueprintReadWrite, 0.0 to 1.0)
  Spawn probability. 1.0 means the actor appears every time, while 0.5 means a 50% chance. When multiple parts are listed, each is evaluated independently, so it is possible for more than one to appear. Lower values make an object feel rarer.

Editing tips

• Register multiple actors with the same role and adjust Frequency to create effects such as "a rare object appears only occasionally."
• Use the base-class transform settings for rotation and position alignment. Matching the actor's forward direction makes placement feel more natural.
