Dear Community,

here are my static library functions for saving a objects path and then loading an object dynamically from a path

I have a templated version of my dynamic load object function for your entertainment!

To test this you could remove the word static and put in any .h file of your choosing like player controller

//Get Path static FORCEINLINE FName GetObjPath(const UObject* Obj) { if(!Obj)

   {
     return NAME\_None;
   }

//~

FStringAssetReference ThePath = FStringAssetReference(Obj);

if(!ThePath.IsValid()) return NAME_None;

//The Class FString Name For This Object FString Str = Obj->GetClass()->GetDescription();

Str += "'"; Str += ThePath.ToString(); Str += "'";

return FName(*Str); }

Because in my In-Game editor I only save the asset references to binary file, and use Dynamic Load Object during the loading of a level, and

FName is half the size of FString, 8 compared to 16 bytes.

So I do it for Save File size-reduction reasons

//TEMPLATE Load Obj From Path template static FORCEINLINE ObjClass* LoadObjFromPath(const FName& Path) { if(Path == NAME_None) return NULL; //~

 return Cast<ObjClass>(StaticLoadObject( ObjClass::StaticClass(), NULL,\*Path.ToString()));

}

// Load PS From Path static FORCEINLINE UParticleSystem* LoadPSFromPath(const FName& Path) { if(Path == NAME_None) return NULL; //~

return LoadObjFromPath(Path); }

// Load Material From Path static FORCEINLINE UMaterialInterface* LoadMatFromPath(const FName& Path) { if(Path == NAME_None) return NULL; //~

return LoadObjFromPath(Path); }

// Load Static Mesh From Path static FORCEINLINE UStaticMesh* LoadMeshFromPath(const FName& Path) { if(Path == NAME_None) return NULL; //~

return LoadObjFromPath(Path); }
