AActor::DebugShowComponentHierarchy

function Engine Since 4.0

#include "GameFramework/Actor.h"

Access: public

Description

Prints the full scene component attachment hierarchy of this actor to the log, optionally showing each component's world-space position. Useful for diagnosing attachment or transform issues.

Caveats & Gotchas

• Output goes to the log via UE_LOG — it is not drawn on screen; you need to check the Output Log or console output.
• This iterates the SceneComponent tree, so only scene components (those with a transform) appear; pure UActorComponents with no scene representation are omitted.

Signature

ENGINE_API void DebugShowComponentHierarchy( const TCHAR* Info, bool bShowPosition  = true);

Parameters

Name	Type	Description	Default
Info	const TCHAR*	Optional label string printed at the top of the hierarchy dump.	—
bShowPosition	bool	If true, prints world-space position for each component.	true

Return Type

void

Example

Dump hierarchy at runtime from console command C++

// Add a console command to an actor for quick debugging
if (APlayerController* PC = GetWorld()->GetFirstPlayerController())
{
    if (APawn* Pawn = PC->GetPawn())
    {
        Pawn->DebugShowComponentHierarchy(TEXT("PlayerPawn"), true);
    }
}
