ItemFrames aren't blocks, they're entities, so you'll never see it with GetBlockState.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

DO NOT PM ME WITH PROBLEMS. No help will be given.

Here is the code

List<Entity> itemFrames = world.getEntities(player, axisalignedBB);
        for (Entity entity: itemFrames) {
            if(entity.getType() == EntityType.ITEM_FRAME){
                ItemFrameEntity Item_Frame = (ItemFrameEntity) entity;
                getNBTDataFromItemFrameItem(Item_Frame, file);
            }
       }

And here is the getNBTDataFromItemFrameItem

public static void getNBTDataFromItemFrameItem(ItemFrameEntity item, File file) throws IOException {
        if(item.getItem().sameItem(new ItemStack(Items.FILLED_MAP))){
            Item map_item = item.getItem().getItem();
            CompoundNBT nbt = map_item.getDefaultInstance().serializeNBT();
            CompressedStreamTools.writeCompressed(nbt, file);
        }
    }

But I have a problem with getting the nbt data of map item.

See FilledMapItem.

public static void getNBTDataFromItemFrameItem(ItemFrameEntity item, World world) throws IOException {
        if(item.getItem().sameItem(new ItemStack(Items.FILLED_MAP))){
            fileCount++;
            File file = new File("anything", "data" + fileCount + ".dat");
            try {
                MapData nbt = FilledMapItem.getOrCreateSavedData(item.getItem(), world);
                assert nbt != null;
                CompressedStreamTools.writeCompressed(nbt.serializeNBT(), file);
                System.out.println("done");
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

Now I just get error that it cant serialize the data

java.lang.NullPointerException
