  • dynamic_rate_adjustment (bool): [Read-Write] Dynamically adjust the sample rate if audio and media clock desynchronize.

  • editable_when_inherited (bool): [Read-Write] True if this component can be modified when it was inherited from a parent actor class

  • enable_base_submix (bool): [Read-Write] If enabled, sound will route to the Master Submix by default or to the Base Submix if defined. If disabled, sound will route ONLY to the Submix Sends and/or Bus Sends

  • enable_bus_sends (bool): [Read-Write] Whether or not to enable sending this audio’s output to buses.

  • enable_submix_sends (bool): [Read-Write] Whether or not to enable Submix Sends other than the Base Submix.

  • envelope_follower_attack_time (int32): [Read-Write] The attack time in milliseconds for the envelope follower. Delegate callbacks can be registered to get the envelope value of sounds played with this audio component. Only used in audio mixer.

  • envelope_follower_release_time (int32): [Read-Write] The release time in milliseconds for the envelope follower. Delegate callbacks can be registered to get the envelope value of sounds played with this audio component. Only used in audio mixer.

  • hidden_in_game (bool): [Read-Write] Whether to hide the primitive in game, if the primitive is Visible.

  • is_editor_only (bool): [Read-Write] If true, the component will be excluded from non-editor builds

  • is_ui_sound (bool): [Read-Write] Whether or not this sound plays when the game is paused in the UI

  • media_player (MediaPlayer): [Read-Write] The media player asset associated with this component.

    This property is meant for design-time convenience. To change the associated media player at run-time, use the SetMediaPlayer method. see: SetMediaPlayer

  • mobility (ComponentMobility): [Read-Write] How often this component is allowed to move, used to make various optimizations. Only safe to set in constructor.

  • on_audio_envelope_value (OnSynthEnvelopeValue): [Read-Write] On Audio Envelope Value

  • on_component_activated (ActorComponentActivatedSignature): [Read-Write] Called when the component has been activated, with parameter indicating if it was from a reset

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

  • override_attenuation (bool): [Read-Write] Should the Attenuation Settings asset be used (false) or should the properties set directly on the component be used for attenuation properties

  • physics_volume_changed_delegate (PhysicsVolumeChanged): [Read-Write] Delegate that will be called when PhysicsVolume has been changed *

  • 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.

  • primary_component_tick (ActorComponentTickFunction): [Read-Write] Main tick function for the Component

  • rate_adjustment_factor (float): [Read-Write] Factor for calculating the sample rate adjustment.

    If dynamic rate adjustment is enabled, this number is multiplied with the drift between the audio and media clock (in 100ns ticks) to determine the adjustment. that is to be multiplied into the current playrate.

  • rate_adjustment_range (FloatRange): [Read-Write] The allowed range of dynamic rate adjustment.

    If dynamic rate adjustment is enabled, and the necessary adjustment falls outside of this range, audio samples will be dropped.

  • relative_location (Vector): [Read-Write] Location of the component relative to its parent

  • 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.

  • source_effect_chain (SoundEffectSourcePresetChain): [Read-Write] The source effect chain to use for this sound.

  • 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.
