Hey, so I have a mod and it was working fine, I could generate blocks without an issue. However it only replaces stone. And so I took a look in 'WorldGenMinable' and there seems to be a magic number for what it replaces, which is only stone. So I tried to do some googling and all that came up were outdated, useless tutorials that use old code for WorldGenMinable that didn't have a magic number.

 

So, can anyone point me in the right direction of how to generate blocks that replaces something other than stone? Even if it's just someone's code on github, anything will help. Thanks!

 

Solution: Add a new parameter for the item to replace, then in your call to WorldGenMinable, use BlockHelper.forBlock(replace)

 

Yea, 1.8 pretty much takes the idea of "Magic Numbers" and hides them.  No more block or item IDs, Entity IDs are almost irrelevant, metadata is now IBlockState...

WorldGenMinable actually doesn't have any "magic number". In 1.8 it takes a Predicate<IBlockState> (which you can think of as a method that takes a IBlockState and returns a boolean) that determines whether a certain block should be replaced or not.

If you just want to replace a single Block, Minecraft has a default implementation for this Predicate, called "BlockHelper". Use BlockHelper.forBlock to get an instance of it for a specific block.

Okay thanks. I saw the Predicate but the lack of naming tripped me up. The actual part I got confused on was:

    public WorldGenMinable(IBlockState p_i45630_1_, int p_i45630_2_)
    {
        this(p_i45630_1_, p_i45630_2_, BlockHelper.forBlock(Blocks.stone));
    }

I thought this was the only definition of something to replace. But I now see that I missed

    public WorldGenMinable(IBlockState p_i45631_1_, int p_i45631_2_, Predicate p_i45631_3_)
    {
        this.oreBlock = p_i45631_1_;
        this.numberOfBlocks = p_i45631_2_;
        this.field_175919_c = p_i45631_3_;
    }

 

Thank you guys!
