UCharacterMovementComponent::AdjustFloorHeight

function Engine Since 4.0

#include "GameFramework/CharacterMovementComponent.h"

Access: public Specifiers: virtual

Description

Nudges the character vertically to maintain a small offset above the current floor (CurrentFloor) after a walking move, keeping the capsule from resting exactly on or penetrating the floor.

Caveats & Gotchas

• Does nothing if CurrentFloor.IsWalkableFloor() is false — it only adjusts height when there's a valid walkable floor result to adjust toward.
• Aborts without adjusting if the floor result came from a line trace with a small floor distance while the sweep distance was already at least MIN_FLOOR_DIST, since applying the adjustment in that case could scale an unwalkable wall.
• Called internally at the end of PhysWalking each iteration; calling it manually outside that context relies on CurrentFloor already being up to date from a prior floor check.
