UE5勉強日記-data tableの使用

Posted at

C++でblueprintから作るdata tableは下記のコードで使用できる。

FString TablePath = TEXT("/Script/Engine.DataTable'/Game/Data/DT_Food.DT_Food'");
    UDataTable* DataTable = Cast<UDataTable>(StaticLoadObject(UDataTable::StaticClass(), nullptr, *TablePath));
    if (!DataTable)
    {
        UE_LOG(LogTemp, Warning, TEXT("Failed to load DataTable at %s"), *TablePath);
        return false;
    }
    TArray<FName> RowNames = DataTable->GetRowNames();
	FName RowName = RowNames[index];
	FFoodStruct* FoodItem = DataTable->FindRow<FFoodStruct>(RowName, TEXT("LookupID"));
	if (FoodItem)
	{
		FoodItem->Inventory++
    }

☆data tableはRowNameで一行のデータを特定する。直接インデックスで特定できない。
FindRow(RowName, TEXT("LookupID"));
は特定行を探す関数です。
RowNameは検索キーワードで、 TEXT("LookupID")は問題発生した時に残る記録です。
