UKismetSystemLibrary::DrawDebugBox

function Engine Blueprint Since 4.0

#include "Kismet/KismetSystemLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Draws a wireframe box for debugging, matching the way box collision or trace shapes are described by center, extent, and rotation.

Caveats & Gotchas

• Extent is a half-extent, matching FBoxSphereBounds/BoxTrace conventions, not the full box dimensions.
• Compiled out entirely in Shipping and Test builds since the UFUNCTION is DevelopmentOnly.

Signature

static void DrawDebugBox(const UObject* WorldContextObject, const FVector Center, FVector Extent, FLinearColor LineColor, const FRotator Rotation=FRotator::ZeroRotator, float Duration=0.f, float Thickness = 0.f, EDrawDebugSceneDepthPriorityGroup DepthPriority = EDrawDebugSceneDepthPriorityGroup::World)

Parameters

Name	Type	Description	Default
WorldContextObject	const UObject*	World context used to resolve which world to draw in.	—
Center	const FVector	World-space center of the box.	—
Extent	FVector	Half-extents of the box along each local axis.	—
LineColor	FLinearColor	Color of the drawn box.	—
Rotation	const FRotator	Orientation of the box.	FRotator::ZeroRotator
Duration	float	How long the box persists, in seconds. 0 draws for a single frame.	0.f
Thickness	float	Line thickness in screen pixels.	0.f
DepthPriority	EDrawDebugSceneDepthPriorityGroup	Whether the box is depth-tested against the scene or always drawn in the foreground.	EDrawDebugSceneDepthPriorityGroup::World

Return Type

void

Example

Visualize a box trace region C++

UKismetSystemLibrary::DrawDebugBox(
    this,
    TraceCenter,
    FVector(50.f, 50.f, 50.f),
    FLinearColor::Green,
    TraceRotation.Rotator(),
    1.0f);
