Member Function Documentation

◆ FindLastKeyBefore()

int32 FRecordedTransformTrack::FindLastKeyBefore ( float  InTime) const
inline

Finds the index of the key immediately before the provided time. Or the exact frame in the case of an exact time match

◆ FindRecordedFrame() [1/2]

FRecordedFrame * FRecordedTransformTrack::FindRecordedFrame ( float  InTime,
float  InTolerance = UE_SMALL_NUMBER 
)
inline

Find a frame at InTime if available within a specified tolarance of the timestamp

◆ FindRecordedFrame() [2/2]

const FRecordedFrame * FRecordedTransformTrack::FindRecordedFrame ( float  InTime,
float  InTolerance = UE_SMALL_NUMBER 
) const
inline

Find a frame at InTime if available within a specified tolarance of the timestamp

◆ FindRecordedFrameIndex()

int32 FRecordedTransformTrack::FindRecordedFrameIndex ( float  InTime,
float  InTolerance = UE_SMALL_NUMBER 
) const
inline

Find a frame index at InTime if available within a specified tolarance of the timestamp

◆ GetAngularVelocityAtTime()

FVector FRecordedTransformTrack::GetAngularVelocityAtTime ( int32  InIndex,
float  InTime,
float  SampleWidth = 1.0f / 120.0f 
) const
inline

Get an interpolated angular velocity for the specified particle at the provided time - using SampleWidth to pick out a window of interpolation

◆ GetDisabledAtTime()

bool FRecordedTransformTrack::GetDisabledAtTime ( int32  InIndex,
float  InTime 
) const
inline

Get whether a particle is disabled at a provided time

◆ GetDt()

float FRecordedTransformTrack::GetDt ( ) const
inline

◆ GetFramesForTime()

void FRecordedTransformTrack::GetFramesForTime ( float  InTime,
const FRecordedFrame *&  OutFirst,
const FRecordedFrame *&  OutSecond 
) const
inline

Given a time, return either one or two frames. If InTime is exactly on a frame then only that frame is returned. If we are beyond the end of the track only the last is returned. For times in the middle of the track that are not exactly on a frame then the frame before and after the time are returned.

◆ GetLinearVelocityAtTime()

FVector FRecordedTransformTrack::GetLinearVelocityAtTime ( int32  InIndex,
float  InTime,
float  SampleWidth = 1.0f / 120.0f 
) const
inline

Get an interpolated linear velocity for the specified particle at the provided time - using SampleWidth to pick out a window of interpolation

◆ GetTransformAtTime()

FTransform FRecordedTransformTrack::GetTransformAtTime ( int32  InIndex,
float  InTime 
) const
inline

Given a time, get an interpolated transform from the track for a provided particle

◆ GetWasActiveInWindow()

bool FRecordedTransformTrack::GetWasActiveInWindow ( int32  InIndex,
float  InBeginTime,
float  InEndTime 
) const
inline

Given two times, find out if the provided particle was ever active within them

◆ IsTimeValid()

bool FRecordedTransformTrack::IsTimeValid ( float  InTime) const
inline

Validates that the time is within the track timestamp bounds (inclusive)

◆ ProcessRawRecordedData()

FRecordedTransformTrack FRecordedTransformTrack::ProcessRawRecordedData ( const FRecordedTransformTrack &  InCache)
static
