Thanks a lot. I just made it!

Okay I will learn it . But I can't modify furnace's tileentity class, it is read-only.

1. Oh... Sorry... When I post my code to the forum I will change "TileEntityVisitor" to "TileEntityA" ... I forget to change it last time ... 2. This is what I want to do... When I click Block B,the furnace next to block B will finish cooking item.

Thanks, I get the tile entity form block A successfully ! BUT... Here is my code of block B. private void cover(TileEntityA t, World world, int x, int y, int z){ t = (TileEntityA) world.getTileEntity(x-1, y, z); //What should I do here to modify the value?? } public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer par5EntityPlayer, int par6, float par7, float par8, float par9) { if(!world.isRemote) { TileEntityVisitor t2 = (TileEntityA) world.getTileEntity(x-1, y, z); if(t != null && t2 != null){ this.cover(t2, world, x, y, z); } } return true; } What should in cover() ?

When I click Block B , the NBT tag of block B will be replace for the NBT tag of block A. I want to modify the NBT tag of block B which is replace for the NBT tag of block A . Then save the modifyed-NBT into block A. (My English is pretty basic ...)

What? Didn't you say that you want to modify "BlockA"'s NBT value? YES, I want to modify the NBT Tag of block A ... When Block B get the value of block A , I want to edit it and save the new value into block A.

But , when Block B get the value , how can I edit the value ??

When I click Block B, it will get the NBT Tag form Block A. And the NBT Tag of Block A will be adjusted then save into Block A. For example, the value of block A is 35 . When I click Block B, it will get the value "35" , and the value will be subtract by 5, then save into Block A.

I want to right click blockB to change the NBT Tag of block A.

What is Block C, and what do you mean by "cover the NBT Tag of Block A"? Sorry for my poor English... Block C is other block which next to Block B. When I click Block B, it will get the NBT Tag form block C and write the NBT Tag of Block C into Block A .

You have to check if the tileentity is your tile entity. try instanceof TileEntityA Okay... Now, when I click block B, Block B can get NBT Tag form Block C and covered the NBT Tag of Block A. But I don't want to use other blocks to cover the NBT Tag of Block A. What should I do?

& World class implements the IBlockAccess, so you can use the parameter "world" of the method "onBlockActivated". You have to check first before casting, that if it is null or it is not instance of TileEntityA. Like this? public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer par5EntityPlayer, int par6, float par7, float par8, float par9) { if(!world.isRemote) { TileEntityA t = (TileEntityA) world.getTileEntity(x-1, y, z); if(t != null){ t.processActivate(par5EntityPlayer, world); } } return true; }

When I click Block B,it's called processActivate and work smoothly. And how can I designate the value in BlockB.java ?
