Wwise SDK 2015.1.9

Set the value of a real-time parameter control (by ID). With this function, you may set a game parameter value on playing id scope. Playing id scope supersedes both game object scope and global scope. Note that busses ignore RTPCs when they are applied on playing id scope. Thus, you may only change bus or bus plugins properties by calling SetRTPCValue() with AK_INVALID_GAME_OBJECT. With this function, you may also change the value of a game parameter over time. To do so, specify a non-zero value for in_uValueChangeDuration. At each audio frame, the game parameter value will be updated internally according to the interpolation curve. If you call SetRTPCValueByPlayingID() with in_uValueChangeDuration = 0 in the middle of an interpolation, the interpolation stops and the new value is set directly. Thus, if you call this function at every game frame, you should not use in_uValueChangeDuration, as it would have no effect and it is less efficient. Refer to RTPCs and Game Objects, RTPCs and Busses and RTPCs and Plug-Ins for more details on RTPC scope.

Returns:

Always AK_Success

Parameters:

	in_rtpcID	ID of the game parameter
	in_value	Value to set
	in_playingID	Associated playing ID
	in_uValueChangeDuration	Duration during which the game parameter is interpolated towards in_value
	in_eFadeCurve	Curve type to be used for the game parameter interpolation
	in_bBypassInternalValueInterpolation	True if you want to bypass the internal "slew rate" or "over time filtering" specified by the sound designer. This is meant to be used when for example loading a level and you dont want the values to interpolate.
