Syntax
class UBoxComponent : public UShapeComponent
Remarks
A box generally used for simple collision. Bounds are rendered as lines in the editor.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
FVector | BoxExtent | The extents (radii dimensions) of the box |
 |
float | LineThickness | Used to control the line thickness when rendering |

void | InitBoxExtent
(
const FVector& InBoxExtent |
Sets the box extents without triggering a render or physics update. |
 |
void | SetBoxExtent
(
FVector InBoxExtent, |
Change the box extent size. This is the unscaled size, before component scale is applied. |
 |
void | SetLineThickness
(
float Thickness |
Set the LineThickness. |
Overridden from UShapeComponent

  |
void | Update the body setup parameters based on shape information |
Overridden from UPrimitiveComponent

|---|---|---|---|
  |
FPrimitiveSceneProxy * | Creates a proxy to represent the primitive to the scene manager in the rendering thread. | |
   |
FCollisionShape | GetCollisionShape
(
float Inflation |
Return a CollisionShape that most closely matches this primitive. |
   |
bool | IsZeroExtent () |
This isn't bound extent, but for shape component to utilize extent is 0. |

FBoxSphereBounds | CalcBounds
(
const FTransform& LocalToWorld |
Calculate the bounds of the component. Default behavior is a bounding box/sphere of zero size. |
