Syntax

static int32 FindDistanceBetweenFramesWithRolloverModulus
(
    const FFrameTime & StartFrameTime,
    const FFrameTime & EndFrameTime,
    const TOptional< FFrameTime > & RolloverModulus,
    bool & bDidRollover
)

Remarks

Calculates the distance between two frames. This method accounts for rollover (when used), and assumes the frames will always be relatively close together. This is also a convenient method to use to check whether or not a rollover has happened within a range of frames.

Parameters

Parameter	Description
StartFrameTime	The start time in the range.
EndFrameTime	The end time in the range.
RolloverModulus	Rollover frame value. Unset if rollover isn't used.
bDidRollover	[out] Whether or not a rollover occurred in the input range.
