Hey there,

I am trying to do this

public void onNeighborBlockChange(World world, int posX, int posY, int posZ, Block neighbourBlock){
 if(world.getBlock(posX, posY - 1, posZ) == blockRegist.cable && world.getBlockMetadata(posX, posY - 1, posZ)  == 1){   
   	 world.setBlock(posX, posY, posZ+1, blockRegist.cable, 1, 1);
    }
    }

in a block class for metadata, but it doesn't work.

I know it's a metadata block, so I didn't expect it to work. But how would I make it so that it works?

 

I am trying to make it so when cable:0 detects cable:1 below it, it will set itself as cable:1 (if that makes sense)

Then you're doing several things wrong.

 

1) That code sets the block to the north, not itself

2) That code never says "am I metadata 0?"

3) That code uses update flag 1, not 3 (you almost always want 3)

1) Yeah, that was just a test

2) I have always tried to avoid meta-blocks, so I don't know how to use them, or do this (I sorta expected it defaults to :0 because when you set block to <metablock> it defaults to :0

3) Oh, I didn't know that.

/**

    * Sets the block ID and metadata at a given location. Args: X, Y, Z, new block ID, new metadata, flags. Flag 1 will

    * cause a block update. Flag 2 will send the change to clients (you almost always want this). Flag 4 prevents the

    * block from being re-rendered, if this is a client world. Flags can be added together.

    public boolean setBlock(int p_147465_1_, int p_147465_2_, int p_147465_3_, Block p_147465_4_, int p_147465_5_, int p_147465_6_)

EXACTLY LIKE HOW YOU CHECK THE BLOCK BELOW IT FOR META 1!  Yeesh.
