UKismetMathLibrary::MakeOrientedBox

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticBlueprintPureUFUNCTION

Description

Creates an FOrientedBox — a rotated bounding box defined by a center, a rotation, and a per-axis half-extent. Use this when an axis-aligned FBox would not tightly fit a rotated object.

Caveats & Gotchas

• FOrientedBox is not accepted by most engine spatial query APIs (overlap tests, traces, spatial hashing) which operate on axis-aligned FBox. When interfacing with those systems you must convert to an AABB first by using FOrientedBox::CalcAABB().
• Extent is the half-size in the box's local coordinate frame **before** Orientation is applied. Confusing local-space extent with world-space dimensions leads to incorrectly sized boxes after rotation.

Signature

static ENGINE_API FOrientedBox MakeOrientedBox(FVector Origin, FRotator Orientation, FVector Extent);

Parameters

Name	Type	Description	Default
Origin	FVector	The center of the box in world space.	—
Orientation	FRotator	The rotation of the box.	—
Extent	FVector	The half-size of the box in local space along each axis.	—

Return Type

FOrientedBox

Example

Create an oriented hitbox matching a rotated actor C++

FVector Center = MyActor->GetActorLocation();
FRotator Rot = MyActor->GetActorRotation();
FVector HalfExtent(80.f, 40.f, 100.f);
FOrientedBox OBB = UKismetMathLibrary::MakeOrientedBox(Center, Rot, HalfExtent);
// OBB is now aligned with MyActor's local axes
