Hi,

I’m trying to create GIS and a manager, and I’m at this point trying to take something in viewport and to collect the data into data table, there is any way to do so?

Last time I checked, Data tables can’t be updated at runtime. Unless you use C++ or a plugin

3

can I use this plugin for invert method? i mean to record from viewport to data table?

As far as I know, yes.

Would like to share how to add a row to a Data Table that is using blueprint structs.
Unfortunately this only works in editor and can’t do a packaged build with it.
In the header file:

	UFUNCTION(BlueprintCallable, BlueprintNativeEvent, meta = (CustomStructureParam = "Struct"))
	void AddToDataTable(UDataTable* inDatatable, FName inRowName, const FString& JsonStructString);

	UFUNCTION(BlueprintCallable, BlueprintNativeEvent)
	void RemoveDataTableRow(UDataTable* inDatatable, FName inRowName);

In the C++ file

void U::AddToDataTable_Implementation(UDataTable* inDatatable, FName inRowName,const FString& JsonStructString)
{
	FString localDatabaseString = inDatatable->GetTableAsJSON();
	FString localJsonStruct = JsonStructString;

	localDatabaseString.RemoveAt(localDatabaseString.Len()-1,1,true);
	localJsonStruct.RemoveAt(0,1,true);

	localJsonStruct = ",{\"Name\": \"" + inRowName.ToString() + "\"," + localJsonStruct;
	localDatabaseString = localDatabaseString + localJsonStruct + "]";
	
	inDatatable->CreateTableFromJSONString(localDatabaseString);
}

void U::RemoveDataTableRow_Implementation(UDataTable* inDatatable, FName inRowName)
{
	inDatatable->RemoveRow(inRowName);
}

Just enable Json Blueprint Utilities Plugin
