FMotionTrajectoryLibrary

Set of functions to help populate a FPoseSearchQueryTrajectory for motion matching.

API > API/Plugins > API/Plugins/MotionTrajectory

Set of functions to help populate a FPoseSearchQueryTrajectory for motion matching. UCharacterTrajectoryComponent uses these functions, but they can also be used by a UAnimInstance to avoid the component.

Name Remarks Include Path Unreal Specifiers

static void InitTrajectorySamples ( FTransformTrajectory& Trajectory,
const FTrajectorySamplingData& SamplingData,
const FVector& Position,
const FQuat& Facing
)

   MotionTrajectoryLibrary.h  

static FVector RemapVectorMagnitudeWithCurve ( const FVector& Vector,
bool bUseCurve,
const FRuntimeFloatCurve& Curve
)

   MotionTrajectoryLibrary.h  

static void UpdateHistory_TransformHistory ( FTransformTrajectory& Trajectory,
TArrayView< FVector > TranslationHistory,
const FCharacterTrajectoryData& CharacterTrajectoryData,
const FTrajectorySamplingData& SamplingData,
float DeltaSeconds
)

 Update history by tracking offsets that result from character intent (e.g. movement component velocity) and applying that to the current world transform. MotionTrajectoryLibrary.h  

static void UpdatePrediction_SimulateCharacterMovement ( FTransformTrajectory& Trajectory,
const FCharacterTrajectoryData& CharacterTrajectoryData,
const FTrajectorySamplingData& SamplingData
)

 Update prediction by simulating the movement math for ground locomotion from UCharacterMovementComponent. MotionTrajectoryLibrary.h
