    Issues getting polygons from navigation system

    I've been toying with this navigation code that has been dated a bit: Here

    I'm not afraid to admit that I'm rather a noob to C++ (I used to do some light C++ YEARS ago).

    Anyway, I've created a custom AIController class with a custom PathFollowingComponent, and have made the following function (Based on the link above)

    Code:
    //Retrieves a list of NavNodeRefs for all polygons in the active navmesh
    bool UMyPathFollowingComponent::GetAllNavPolygons(TArray<NavNodeRef> &PolyRefs)
    {
    	//Get the active navigation system
    	UNavigationSystem* NavSys = GetWorld()->GetNavigationSystem();
    	//Check that the NavSys is valid
    	if (NavSys) {
    		//Log
    		UE_LOG(LogClass, Log, TEXT("NavSys = true"));
    
    		//Agent properties used for navigation
    		const FNavAgentProperties& AgentProperties = MovementComp->GetNavAgentPropertiesRef();
    		//Navdata filter to get the navdataforprops
    		const ANavigationData* NavData = NavSys->GetNavDataForProps(AgentProperties);
    
    		//Check if we have a valid movementcomponent
    		if (MovementComp) {
    			//Log
    			UE_LOG(LogClass, Log, TEXT("MoveComp = true"));
    
    			//Get the navmesh filtered from NavData
    			const ARecastNavMesh* NavMesh = Cast<ARecastNavMesh>(NavData);
    			//Check that the NavMesh is valid
    			if (NavMesh) {
    				//Log
    				UE_LOG(LogClass, Log, TEXT("NavMesh = true"));
    
    				//Temporarily holds polygon data from GetPolysInTile
    				TArray<FNavPoly> EachPolys;
    				//Used for valid tile checking
    				FBox TileBounds;
    
    				//Go through all tiles in the NavMesh
    				for (int32 v = 0; v < NavMesh->GetNavMeshTilesCount(); v++)
    				{
    					//Log
    					UE_LOG(LogClass, Log, TEXT("Checking Tile %d"), v);
    
    					//Test if the TileBounds indicates a valid or invalid tile
    					TileBounds = NavMesh->GetNavMeshTileBounds(v);
    					//Skip the rest of the loop on an invalid tile
    					if (TileBounds.IsValid != 0) { continue; }
    					//Log
    					UE_LOG(LogClass, Log, TEXT("Tile Valid!"));
    
    					//Get the polygons on the current tile
    					NavMesh->GetPolysInTile(v, EachPolys);
    					//Log
    					UE_LOG(LogClass, Log, TEXT("Found %d Polys"), EachPolys.Num());
    
    					//Add polygon references to PolyRefs
    					if (EachPolys.Num() > 0) {
    						UE_LOG(LogClass, Log, TEXT("Adding first element only - as test"));
    						PolyRefs.Add(EachPolys[0].Ref);
    					}
    				}
    				return true; //success after loop
    			}
    		}
    	}
      return false; //failure - loop never executed
    }
    Whenever I run this in the editor, my log shows the following output:

    Code:
    LogClass: NavSys = true
    LogClass: MoveComp = true
    LogClass: NavMesh = true

    In short, I am finding NO polygons on my navmesh, even though I definitely do have a navmesh.

    I've been poking around online to find some help/documentation on this - but it appears that the AI navigation features in UE4 are missing a lot of documentation. Does anyone have any thoughts on what I might be doing wrong?

    #2
    Of course I solve it a few moments after I post it.

    For anyone who might stumble across this, the line which reads:

    if (TileBounds.IsValid != 0) { continue; }

    Just needs to be adjusted to:

    if (TileBounds.IsValid == 0) { continue; }

    I was trying to get polygons from invalid tiles.
