virtual void FindSampleIndexesFromTime
(
float Time,
bool bLooping,
bool bIsPlayingBackwards,
int32 & OutFrameIndex,
int32 & OutNextFrameIndex,
float & InterpolationFactor
)
Remarks
Find the two frames closest to the given time InterpolationFactor gives the position of the requested time slot between the two returned frames. 0.0 => We are very close to OutFrameIndex 1.0 => We are very close to OutNextFrameIndex If bIsPlayingBackwards it will return exactly the same indexes but in the reversed order. The InterpolationFactor will also be updated accordingly
