AkComponent Blueprint Functions

Several Wwise-specific actions can be executed on AkComponent scene components; these are available in the Ak Component category.

Get Attenuation Radius

Returns this AkComponent's effective attenuation radius (ScalingFactor * MaxAttenuation).

Post Ak Event

Posts the specified AkAudioEvent in Wwise.

Post Associated Ak Event

Posts this AkComponent's internal AkAudioEvent in Wwise.

Post Trigger

Posts a trigger on the associated AkComponent.

Set Attenuation Scaling Factor

Sets the attenuation scaling factor, which modifies the attenuation computations on the game object to simulate sounds with a larger or smaller area of effection.

Set Listeners

Sets the listeners on the AkComponent.

Set Occlusion Refresh Interval

Sets the time interval at which the AkComponent performs occlusion calculations. Set to 0 to turn off occlusion on the component.

Set Output Bus Volume

Set the output bus volume (direct) to be used for the specified game object. The Bus Volume value is a number ranging from 0.0f to 1.0f.

Set RTPC Value

Sets the value of a Game Parameter for the associated AkComponent.

Set Stop when Owner Destroyed

Sets the StopWhenOwnerDestroyed value on the corresponding AkComponent.

Set Switch

Sets a Switch Group to a given Switch on the associated AkComponent.

Stop

Stops the AkAudioEvent associated with the AkComponent from playing.

Use Early Reflections

Enables (or disables) early refelction for this Ak Component.

Use Reverb Volumes

Sets whether the AkComponent is influenced by AkReverbVolume or not.
