Hi.
I need to find in my game package all blueprints, wich has same parent BP.
For example, my Wood_Table_Blueprint has parent BP, named as FurnitureMainClass.
I need to finds all BPs in game package. Please do not confuse this task with finding BPs, that placed at the scene and could be founded by Get All Actors By Class.
My task is different. I need to find BPs in game package (ie, in file system) and build.
I need it for building my Game Inventory Menu.
Solved with the code
UObject * AMyNativePlayerController::MyGetAsset(FAssetData & asset) {
if (!asset.IsValid())
{
return NULL;
}
UObject * Asset = FindObject<UObject>(NULL, *asset.ObjectPath.ToString());

In this example will be selected items, which parented by AMyFurnitureActor BP.
