  |
FPrimitiveSceneProxy * | Creates a proxy to represent the primitive to the scene manager in the rendering thread. | |
   |
bool | Determines whether the proxy for this primitive type needs to be recreated whenever the primitive moves. |

FBoxSphereBounds | CalcBounds
(
const FTransform& LocalToWorld |
Calculate the bounds of the component. Default behavior is a bounding box/sphere of zero size. |
Overridden from UActorComponent
| Type | Name | Description | |
|---|---|---|---|
  |
void | OnRegister () |
Called when a component is registered, after Scene is set, but before CreateRenderState_Concurrent or OnCreatePhysicsState are called. |
Overridden from UObject
| Type | Name | Description | |
|---|---|---|---|
  |
void | PostEditChangeProperty
(
FPropertyChangedEvent& PropertyChangedEvent |
Called when a property on this object has been modified externally |

   |
bool | GetNavigationLinksArray
(
TArray< FNavigationLink >& OutLink, |
Optional way of retrieving navigation link data - if INavLinkHostInterface implementer defines custom navigation links then it can just retrieve a list of links |
   |
bool | GetNavigationLinksClasses
(
TArray< TSubclassOf< class UNavLinkDefinition > >& OutClasses |
Retrieves UNavLinkDefinition derived UClasses hosted by this interface implementer |
