Loading .csv at runtime Unreal4

Development Programming & Scripting

Hey I’m working in unreal and I’m trying to import a .csv asset as a data table at run time. This is my function below and it works for assets that are already imported into unreal but not for new assets.

Imported Data Path = DataTable’/Game/Blueprints/Data/ImportedData.ImportedData’

It doesn’t work when I point it at the new file in the same folder it returns nothing

New Data Pathpath = DataTable’/Game/Blueprints/Data/NewData.csv’(or NewData.NewData)

I feel like I am missing a step, like defining the new files structure or the cast is failing because it isn’t a “UDataTable” yet. Any suggestions?

UDataTable * UUlyssesBPFunctions::LoadTableByPath(FName Path, bool& result)
{
result = false;

if (Path == NAME_None) return NULL;

UDataTable* LoadedTable = Cast<UDataTable>(StaticLoadObject(UDataTable::StaticClass(), NULL, *Path.ToString()));

return LoadedTable;
}

Hello, the loading code should be correct. I think it might be the path.
Can you try these ones :

  • /Game/Blueprints/Data/NewData
  • /Game/Blueprints/Data/NewData.NewData
  • DataTable’/Game/Blueprints/Data/NewData’

?

Haaaaa ! I thought you import your csv as a DataTable in the editor before trying to load it. You won’t be able to load it like this indeed, whatever the path is. I think the LoadObject functions load only .uasset.
So 2 solutions :

  • create a datable then import csv into it
  • manually load the file. So use your own read file functions to load content, then you can create a raw DataTable (NewObject()) and use function “CreateTableFromCSVString(const FString& InString)” to parse your file and get your rows loaded (I never used the function but from the name, it should be ok)
