Conversion error in FObjectFinder

Development Programming & Scripting
1

I’m working on an inventory system and using FObjectFinder to find the Item database in my editor.
Here is my code:

#include "MeatGameState.h"
#include "UObject/ConstructorHelpers.h"

AMeatGameState::AMeatGameState()
{
	const FString BP_ITEMDB = "DataTable'/Game/Data/ItemDB.ItemDB'";
	static ConstructorHelpers::FObjectFinder<UDataTable> BP_ItemDB(*BP_ITEMDB);
	ItemDB = BP_ItemDB.Object;
}

And this is my error:

2>  [1/4] MeatGameState.cpp
2>C:\Program Files\Epic Games\UE_4.24\Engine\Source\Runtime\CoreUObject\Public\UObject/ConstructorHelpers.h(110): error C2664: 'void ConstructorHelpers::ValidateObject(UObject *,const FString &,const TCHAR *)': cannot convert argument 1 from 'T *' to 'UObject *'
2>          with
2>          [
2>              T=UDataTable
2>          ]

Im not really sure why this is happening or what Im doing wrong. Thanks for any help.

Did you try something like this?

 AMeatGameState::AMeatGameState()
 {
     const FString BP_ITEMDB = "DataTable'/Game/Data/ItemDB.ItemDB'";
     ItemDB = ConstructorHelpers::FObjectFinder<UDataTable>(*BP_ITEMDB).Object;
 }

Actually, there is another thing that came to my mind. The error might be caused because there is no include for the UDataTable class.

Do you have this on top of your .cpp file?

#include "Engine/DataTable.h"

yeah that reply was to just seting itemDb to the construction helper and skipping creating the variable BP_ITEMDB

it may be your asset, the resource stored in BP_ITEMDB cannot be loaded as a UObject, so it mentioned that convert fail
