Functions

Public

Name Remarks Include Path Unreal Specifiers

void GetRPMRange ( FVector2D& OutRPMRange
)

 Returns the min and max RPM range, taking into account the acceleration and deceleration data. MotoSynthEngine.h  

void Init ( int32 InSampleRate
)

   MotoSynthEngine.h  

void Reset()

   MotoSynthEngine.h  

void SetPitchScale ( float InPitchScale
)

 Sets a pitch scale on the moto synth to scale up or down the pitch of the output. MotoSynthEngine.h  

void SetRPM ( float InRPM,
float InTimeSec
)

 Sets the RPM directly. Used if the engine is in ManualRPM mode. Will be ignored if we're in simulation mode. MotoSynthEngine.h  

void SetSourceData ( uint32 AccelerationSourceID,
uint32 DecelerationSourceID
)

 Sets all the source data for the moto synth. MotoSynthEngine.h
