Detailed Description

Holds the static meshes and instances necessary for building a city map.

Definition at line 20 of file CityMapMeshHolder.h.

Constructor & Destructor Documentation

◆ ACityMapMeshHolder()

ACityMapMeshHolder::ACityMapMeshHolder ( const FObjectInitializer & ObjectInitializer )

Initializes the mesh holders.

It is safe to call SetStaticMesh after this. However, instances cannot be added until OnConstruction is called.
