I want to create a block equal to another block already existing at

 

BlockPos changePos

 

currently I'm creating a new block, but only with the default IBlockState

 

IBlockState newBlockState = usedBlock.getBlockState().getBaseState();
worldIn.setBlockState(changePos, newBlockState, 3);

(usedBlock is of type Block, worldIn of type World)

 

Now my idea for the time being is to check for certain block types (stone, flowers, wool etc) the known block states and set them into the new IBlockState. That's a bit crude, but currently the only idea I have to solve this issue.

 

So I'm planing to ask if the new Block is of type BlockStone. If so, I'll ask for the VARIANT and set it in the new IBlockState with the withProperty method.

 

But I'm running into a basic understanding problem ... I can't manage to wrap my head around how to ask for the VARIANT property of a existing block, starting with a BlockPos.

 

Can anybody point me into the right direction?

You should just use metadata. Metadata is the only way to persist BlockStates anyway. If blockstate1 and blockstate2 have the same metadata of 0, then it will default to the blockstate set to 0(if not setup correctly the defasult blockstate).

Don't ever invoke metadata directly.

 

If you want to make a block have the same blockstate at another position...

 

IBlockState thatState = world.getBlockState(thatPos);
world.setBlockState(thisPos, thatState, 3);

 

Your problem is that you invoked

getBaseState()

which overwrote whatever state was already in the world with a default state.

many thanks, that was exactly the pointer I needed

I had still been thinking in blocks or blocktypes as the main identifier for blocks. But now I've understood the blockstate is the main thing and blocktype is only a part of the block state.

 

Now my mod is working as expected even with different flowers, wood and stone types ect...
