Variables

Name Description

Public variable

TSubclassOf< cl...

 

AreaClass

Navigation area type that will be use when this static mesh is used as a navigation obstacle.

Public variable

uint32: 1

 

bCreateOnClient

If false, will not create nav collision when connecting as a client

Public variable

uint32: 1

 

bForceGeometryRebuild

If set, convex geometry will be rebuild instead of using cooked data

Public variable

uint32: 1

 

bGatherConvexGeometry

If set, convex collisions will be exported offline for faster runtime navmesh building (increases memory usage)

Setup

(

Public function Virtual

void

 

GetResourceSizeEx

(
    FResourceSizeEx& CumulativeResourc...
)

Get the size of the object/resource for use in memory tools or to display to artists/LDs in the Editor This is the extended version which separates up the used memory into different memory regions (the actual definition of which may be platform specific).

Public function Virtual Const

bool

 

NeedsLoadForClient()

Called during saving to determine the load flags to save with the object.

Public function Virtual Const

bool

 

NeedsLoadForTargetPlatform

(
    const ITargetPlatform* TargetP...
)

Called during saving to determine the load flags to save with the object.

Public function Virtual

void

 

PostInitProperties()

Called after the C++ constructor and after the properties have been initialized, including those loaded from config.

Public function Virtual

void

 

PostLoad()

Do any object-specific cleanup required immediately after loading an object.

Public function Virtual

void

 

Serialize

(
    FArchive& Ar
)

Handles reading, writing, and reference collecting using FArchive.
