Override block with custom one

My aim is to let Mycelium spread over grass and not just dirt
So i got my custom block

Code:

public class BlockMycelCustom extends BlockMycel

and im rewriting the Mycelium entry in Block.REGISTRY at onLoad() with

Code:

Block.REGISTRY.a(110, new MinecraftKey("mycelium"), new BlockMycelCustom() );

though my block never gets ticked, and instead of spreading it now sets the target block to AIR
Now i checked where Blocks.MYCELIUM points and it was ofc the old class, so i changed it to point to my block instead

So far so good,
nothing changed, its still only spreadign to dirt and sets the target block to air

 

@Azuna1
I thought that it was "Block.a( int, String, Block)" but, looking into the source I find that you can do what you're doing
Try doing "Block.REGISTRY.a(110, "mycelium", (new BlockMycelCustom()).c(0.6F).a(h).c("mycel").d("mycelium"));" (As found in the official code)

Might not work but, hey. At least it's worth a shot right?

Edit: You may also want to look into the BlockMycel code and find where it only spreads to dirt, then change this to allow it to also spread to grass.

 

@TGRHavoc the registration works fine
and you cant just change the NMS file, anyway the fix is:
i was totaly ignoring this:

Show Spoiler Hide Spoiler

Code:

iterator = Block.REGISTRY.iterator();
while (iterator.hasNext())
{
    block13 = (Block) iterator.next();
    Iterator iterator1 = block13.O().a().iterator();
    while (iterator1.hasNext())
    {
        IBlockData iblockdata = (IBlockData) iterator1.next();
        int i = Block.REGISTRY.b(block13) << 4 | block13.toLegacyData(iblockdata);

        Block.d.a(iblockdata, i);
    }
}

 

Hey, thanks for posting how you solved it, I spent the whole morning trying to figure out how to get my custom block to work on 1.8 until I read this. =)
