UCharacterMovementComponent::ShouldCheckForValidLandingSpot

function Engine Since 4.0

#include "GameFramework/CharacterMovementComponent.h"

Access: public Specifiers: virtual

Description

Determines whether an impact during falling movement hit the edge of a surface, such that a downward sweep might find a walkable landing spot above the edge rather than treating the hit as a wall.

Caveats & Gotchas

• Only returns true when the hit's Normal and ImpactNormal differ significantly — a flat wall hit where they match always returns false here, regardless of DeltaTime or Delta.
• DeltaTime and Delta are accepted but unused by the base implementation; they exist so subclasses can override with velocity- or timestep-dependent logic.

Signature

virtual bool ShouldCheckForValidLandingSpot(float DeltaTime, const FVector& Delta, const FHitResult& Hit) const

Parameters

Name	Type	Description	Default
DeltaTime	float	Time step for the current movement update.	—
Delta	const FVector&	The move delta that produced the hit.	—
Hit	const FHitResult&	Hit result from the falling-movement impact.	—

Return Type

bool

Example

Decide whether to re-check the landing spot after an edge hit C++

if (ShouldCheckForValidLandingSpot(deltaTime, Delta, Hit))
{
	const FVector PawnLocation = UpdatedComponent->GetComponentLocation();
	FFindFloorResult FloorResult;
	FindFloor(PawnLocation, FloorResult, false);
	if (FloorResult.IsWalkableFloor())
	{
		ProcessLanded(FloorResult.HitResult, deltaTime, Iterations);
	}
}
