Wwise SDK

Sets 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. 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 RTPC 和游戏对象, RTPC 与总线 and RTPC 与插件 for more details on RTPC scope.

• AK_Success if successful
• AK_PlayingIDNotFound if in_playingID is not found.
• AK_InvalidID if in_pszRtpcName is NULL.
• AK_InvalidFloatValue if the value specified was NaN, Inf or FLT_MAX (3.402823e+38)

参数

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 don't want the values to interpolate.
