UCharacterMovementComponent::GetLedgeMove
#include "GameFramework/CharacterMovementComponent.h"
Access: public
Specifiers: virtualconst
Description
Computes a replacement move delta that slides the character along a ledge instead of walking off it, based on the original Delta and the last known floor.
Caveats & Gotchas
- • Returns FVector::ZeroVector if no valid sideways move is found via CheckLedgeDirection(), which callers must handle as 'no ledge slide available.'
- • The returned delta is a substitute for the original Delta, not an addition to it — apply it in place of the move that went over the ledge, not on top of it.
- • Purely a computation helper; it does not itself move the character or change MovementMode.

FVector UMyCharacterMovementComponent::GetLedgeMove(const FVector& OldLocation, const FVector& Delta, const FFindFloorResult& OldFloor) const
{
const FVector SlideDelta = Super::GetLedgeMove(OldLocation, Delta, OldFloor);
UE_LOG(LogTemp, Verbose, TEXT("Ledge slide delta: %s"), *SlideDelta.ToString());
return SlideDelta;
