Remarks

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.

Functions

  Type Name Description
Public function Static void

InitTrajectorySamples ( FPoseSearchQueryTrajectory& Trajectory,
const FTrajectorySamplingData& SamplingData,
const FVector& Position,
const FQuat& Facing
)

  
Public function Static void

UpdateHistory_TransformHistory ( FPoseSearchQueryTrajectory& 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.
Public function Static void Update prediction by simulating the movement math for ground locomotion from UCharacterMovementComponent.
