C++ (Cpp) FRichCurve::FindKey Examples

Example #1

File: MatineeImportTools.cpp Project: RandomDeveloperM/UE4_Hairworks

void FMatineeImportTools::SetOrAddKey( FRichCurve& Curve, float Time, float Value, float ArriveTangent, float LeaveTangent, EInterpCurveMode MatineeInterpMode )
{
	FKeyHandle KeyHandle = Curve.AddKey( Time, Value, false, Curve.FindKey( Time ) );
	FRichCurveKey& Key = Curve.GetKey( KeyHandle );
	Key.ArriveTangent = ArriveTangent;
	Key.LeaveTangent = LeaveTangent;
	Key.InterpMode = MatineeInterpolationToRichCurveInterpolation( MatineeInterpMode );
	Key.TangentMode = MatineeInterpolationToRichCurveTangent( MatineeInterpMode );
}

Example #2

File: MovieSceneSection.cpp Project: zhaoyizheng0930/UnrealEngine

void UMovieSceneSection::AddKeyToCurve(FRichCurve& InCurve, float Time, float Value, EMovieSceneKeyInterpolation Interpolation, const bool bUnwindRotation)
{
	if (IsTimeWithinSection(Time))
	{
		if (TryModify())
		{
			FKeyHandle ExistingKeyHandle = InCurve.FindKey(Time);
			FKeyHandle NewKeyHandle = InCurve.UpdateOrAddKey(Time, Value, bUnwindRotation);

			if (!InCurve.IsKeyHandleValid(ExistingKeyHandle) && InCurve.IsKeyHandleValid(NewKeyHandle))
			{
				MovieSceneHelpers::SetKeyInterpolation(InCurve, NewKeyHandle, Interpolation);
			}
		}
	}
