Syntax

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
