  • on_component_deactivated (ActorComponentDeactivateSignature): [Read-Write] Called when the component has been deactivated

  • pre_effect_bus_sends (Array(SoundSourceBusSendInfo)): [Read-Write] This sound will send its audio output to this list of buses if there are bus instances playing before source effects are processed.

  • relative_rotation (Rotator): [Read-Write] Rotation of the component relative to its parent

  • relative_scale3d (Vector): [Read-Write] Non-uniform scaling of the component relative to its parent. Note that scaling is always applied in local space (no shearing etc)

  • replicates (bool): [Read-Write] Is this component currently replicating? Should the network code consider it for replication? Owning Actor must be replicating first!

  • should_update_physics_volume (bool): [Read-Write] Whether or not the cached PhysicsVolume this component overlaps should be updated when the component is moved. see: GetPhysicsVolume()

  • sound_class (SoundClass): [Read-Write] Sound class this sound belongs to

  • sound_submix (SoundSubmixBase): [Read-Write] Submix this sound belongs to

  • sound_submix_sends (Array(SoundSubmixSendInfo)): [Read-Write] An array of submix sends. Audio from this sound will send a portion of its audio to these effects.

  • use_attach_parent_bound (bool): [Read-Write] If true, this component uses its parents bounds when attached. This can be a significant optimization with many components attached together.

  • visible (bool): [Read-Write] Whether to completely draw the primitive; if false, the primitive is not drawn, does not cast a shadow.
