Remarks

NavMovementComponent defines base functionality for MovementComponents that move any 'agent' that may be involved in AI pathfinding.

Variables

  Type Name Description
Protected variable uint8: 1 bStopMovementAbortPaths If set, StopActiveMovement call will abort current path following request
Protected variable uint8: 1 bUpdateNavAgentWithOwnersCollision If set to true NavAgentProps' radius and height will be updated with Owner's collision capsule size
Protected variable uint8: 1 bUseAccelerationForPaths If set, pathfollowing will control character movement via acceleration values.
Protected variable uint8: 1 bUseFixedBrakingDistanceForPaths If set, FixedPathBrakingDistance will be used for path following deceleration
Protected variable float FixedPathBrakingDistance Braking distance override used with acceleration driven path following (bUseAccelerationForPaths)
Public variable FMovementProperties MovementState Expresses runtime state of character's movement.
Public variable FNavAgentProperties NavAgentProps Properties that define how the component can move.

GetPathFollowingBrakingDistance ( float MaxSpeed
)

 Returns braking distance for acceleration driven path following
Public function Virtual Const bool Returns true if currently crouching
Public function Virtual Const bool Returns true if currently falling (not flying, in a non-fluid volume, and not on the ground)
Public function Virtual Const bool Returns true if currently flying (moving through a non-fluid volume without resting on the ground)
Public function Const bool Returns true if component is allowed to jump
Public function Virtual Const bool Returns true if currently moving on the ground (e.g. walking or driving)
Public function Virtual Const bool Returns true if currently swimming (moving through a fluid volume)

RequestDirectMove ( const FVector& MoveVelocity,
bool bForceMaxSpeed
)

 Path following: request new velocity
Public function Virtual void

RequestPathMove ( const FVector& MoveInput
)

 Path following: request new move input (normal vector = full strength)

SetJumpAllowed ( bool bAllowed
)

 Sets whether this component is allowed to jump
Public function void  
Public function void

SetUpdateNavAgentWithOwnersCollisions ( bool bUpdateWithOwner
)

  
Public function Const bool  
Public function Virtual void Stops applying further movement (usually zeros acceleration).

)

  
Public function void

UpdateNavAgent ( const UCapsuleComponent& CapsuleComponent
)

  
Public function Const bool  

Overridden from UMovementComponent
