Hi,

 

I'm wondering how to read data in from an NBTTagList in Minecraft 1.11.2.

Just to mention, I'm storing a HashSet in the NBTTagList, not sure if this is the best way to go.

 

My current code:

    @Override
    public NBTTagCompound writeToNBT(NBTTagCompound compound) {
        NBTTagList list = new NBTTagList();
        for(BlockPos pos : this.connected_machines) {
            NBTTagCompound com = new NBTTagCompound();
            com.setInteger("posX", pos.getX());
            com.setInteger("posY", pos.getY());
            com.setInteger("posZ", pos.getZ());
            list.appendTag(com);
        }
        compound.setTag("machines", list);
        
        return super.writeToNBT(compound);
    }
    
    @Override
    public void readFromNBT(NBTTagCompound compound) {
        super.readFromNBT(compound);
        
        NBTTagList list = compound.getTagList("machines", type);
    }

 

Thx in advance.

Use NBTTagList#tagCount to get the number of tags in the list and NBTTagList#getCompoundTagAt to get the compound tag at the specified index of the list.

 

There are several other specialised NBTTagList#get[Type]At methods that return the number/array/string at the specified index and a general-purpose NBTTagList#get method that returns the NBTBase at the specified index.

Ah, ok.

Also what type should I put into there: 

compound.getTagList("machines", type);

And from where do I get these types? I guess NBTBase, thought.

The second argument of NBTTagCompound#getTagList is the type ID of the tags contained in the list. Use the IDs from the Constants.NBT class.

 

For a list of compound tags, pass Constants.NBT.TAG_COMPOUND as the second argument.
