Bind this Game Parameter to a built-in value calculated inside the sound engine. Choose one of the following:
(See more about the following built-in parameters in Available built-in parameters.)
Note: Using the built-in parameters to control an RTPC can lead to problems if that RTPC is tied to Initial Delay or Priority. Built-in parameters are computed when a sound plays on a given game object, so they work well for most sound properties. Logical control of playback items like Initial Delay and Priority are not suited while using the built-in parameters to control an RTPC since their value is unknown at the moment the Play Action is posted.
Default value: None
