Hi!

How to?

1) Check block has sub-blocks or not? (like wood block)

2) If block has sub-blocks, how to iterate and get their?

The getSubBlocks() method should return a list of the variations on the block.

I  can't understand, how to correctly get the Block object from list.

All my tries makes crash

What have you tried? Show us some code, please.

i want to build array of all the Block objects with sub-blocks if block has it.

if i build this array without sub-blocks, all my things are working fine.

my code:

int elementsCount = 0;

    public static void getBlockList(){
   	 Iterator it = Block.blockRegistry.iterator();
   	 for (boolean b=true; b==true; b=it.hasNext()){
   		 Block block = (Block)it.next();
   		 List list = new ArrayList();
   		 block.getSubBlocks(Item.getItemFromBlock(block), null, list);
   		 System.out.println(list.size());
   		 if (list.size()>1){
                    for (int i=0; i<list.size(); i++){
  		    ItemStack stack = (ItemStack)list.get(i);
   		    blocks[elementsCount] = Block.getBlockFromItem(stack.getItem());
   		    System.out.println(stack.getItem().getUnlocalizedName());
   		    System.out.println(Block.getIdFromBlock(blocks[elementsCount])+" : "+blocks[elementsCount].getLocalizedName());
   		    ++elementsCount;
  		 }
   		 }
   				 
   	 }
}

It's working, but blocks array is filling with the same blocks (not sub-blocks). E.G. wool block has 16 sub-blocks (aka sub-types) with different colors. But all 16 elements of my array is filling with only first type of wool (white wool). Same situation with wood, planks, saplings e.t.c.

Is it fixable?

and i also need to get localized names of each sub-block.

Okay first of all

 

What is that for loop? Just use a while statement.

 

Anyway, what are you trying to ACTUALLY do? What do you need this array for?

 

And what do you mean by it not working? If it crashed, what was the crash report?

I'm trying to build blocks list in my custom GUI to select block which i need to use in next operation.

It's no crashes and no errors.

sorry, i make tag mistake in my previous post. Answer is located in the and of previous post. But i repeat it:

That's because the sub-blocks aren't actually blocks, they're ItemStacks with metadata values.

 

If you want an array of blocks that have sub blocks, that's fine. But if you want to actually store all the actual sub blocks themselves, you're going to need an ItemStack array/list.

THANK YOU! It's working! 

But how to get localized names of sub-blocks?

I think there's a getLocalizedName method for every block. But if there isn't I'm pretty sure you can use StatCollector#translateToLocal or something

It's return first block name only
