APawn::UpdateNavigationRelevance

function Engine Since 4.0

#include "GameFramework/Pawn.h"

Access: public Specifiers: virtual

Description

Override to propagate the `bCanAffectNavigationGeneration` flag to the relevant components when it changes at runtime. The base implementation does nothing.

Caveats & Gotchas

• You must override this in your Pawn subclass if it owns components that should affect navmesh generation — the default implementation is a no-op, so nothing will actually update without your override.
• Only has an effect at runtime if runtime navigation generation is enabled in Project Settings. Changes in a cooked/baked navmesh build are ignored.

Signature

virtual void UpdateNavigationRelevance()

Return Type

void

Example

Propagate nav relevance to mesh component C++

void AMyPawn::UpdateNavigationRelevance()
{
	Super::UpdateNavigationRelevance();
	if (MeshComponent)
	{
		MeshComponent->SetCanEverAffectNavigation(bCanAffectNavigationGeneration);
	}
}
