Hi,

 

I'm wondering how to register my blocks in 1.9:

 

In 1.8.9 I used these to methods for it:

this.registerBlock(() -> "sand");
this.registerBlock(() -> "stone", ItemStone.class);

    public void registerBlock(IName name) {
        this.setUnlocalizedName(Constants.MOD_ID.toLowerCase() + "." + name.getName());
        this.setRegistryName(name.getName());
        GameRegistry.registerBlock(this);
    }

    public void registerBlock(IName name, Class<? extends ItemBlock> iblock) {
        this.setUnlocalizedName(Constants.MOD_ID.toLowerCase() + "." + name.getName());
        this.setRegistryName(name.getName());
        GameRegistry.registerBlock(this, iblock);
    }

 

IName is a functional interface.

 

Now in 1.9 I tried this:

this.register(() -> "sand");

    public void register(IName name) {
        this.setUnlocalizedName(Constants.MOD_ID.toLowerCase() + "." + name.getName());
        this.setRegistryName(name.getName());
        GameRegistry.register(this);
    }

 

But this is not working. So anyone who got an idea?

And what is required to get the ItemBlock's updated?

 

Thx in advance.

The interface came because I wanted to test the Java 8 Lambda expressions out in Minecraft modding and found no other place where I can put

a lambda expression in, so I did it there for testing.

 

Well, this does not work. When I use GameRegistry.register(thing) is my block gone. For some reasons it seems to work for items, but not for blocks.

 

So when I use this register(IName name, ItemBlock iblock) { and then this

        GameRegistry.register(this);
        GameRegistry.register(iblock);

I can't pass my ItemStone block which extends von ItemBlockBase which extends from ItemBlock.

 

(all my GameRegistry.register stuff is in abstract classes in methods there which will be called from the class which extends from the abstract class in the constructor.)

Well, but it's not working and the only thing I'm doing is having the method register in the abstract class BlockBaseLeaves.

 

    public void register(IName name) {
        this.setUnlocalizedName(Constants.MOD_ID.toLowerCase() + "." + name.getName());
        this.setRegistryName(name.getName());
        GameRegistry.register(this);
    }

 

Then I call this method in the class BlockLeaves in the constructor. (class BlockLeaves extends BlockBaseLeaves).

 

    public BlockLeaves() {
        super();
        
        this.register(() -> "leaves");
    }

 

That's all what I am doing.

With the old GameRegistry.registerBlock everything works fine, but with the new GameRegistry.register it does not work.

Define "does not work". The code you posted will (as I said above) not create an ItemBlock, meaning your Block cannot exist in any inventory.

The BlockLeaves is currently not an item block. Just did it not with item blocks because when it's not working for normal blocks it will not work for item blocks, too and before

I make a mistake in item block and can't find it because there is already one in block.... So I tested it now without ItemBlock.

 

And with "does not work" I mean, I'm getting no error, but when I want to join the world Forge tells me about the missing block "leaves" and when I then join even when the block is missing the block is not shown in the creative inventory and I can't give it to me with the command /give.

So I have to create for every block a new class which extends from ItemBlock? (which I currently just have for one block)

Right?

So this gives me a crash:

    public void register(IName name) {
        this.setUnlocalizedName(Constants.MOD_ID.toLowerCase() + "." + name.getName());
        this.setRegistryName(name.getName());
        GameRegistry.register(this);
        GameRegistry.register(new ItemBlock(this));
    }

 

java.lang.IllegalArgumentException: No registry name set for object net.minecraft.item.ItemBlock@1ed763aa (net.minecraft.item.ItemBlock)

 

So do I have to give my item block an extra registry name, even when the block has still one?

 

And how can I do this with custom ItemBlocks, I mean, which paramenter must I just in my method to be able to pass this parameter to the GameRegistry thing?

Set the

ItemBlock

's registry name to the

Block

's registry name.

 

To handle custom

ItemBlock

classes, you can use a

Function<Block, ItemBlock>

argument (i.e. a function that takes a

Block

and returns an

ItemBlock

) as a factory for the

ItemBlock

instance. I do this here.

Ok, thx. Now it's working perfectly.
