Set a block ignoring its neighbors

[thebest108]

How would I be able to set a block(Like redstone) in the air without it not placing? Im trying to copy things from 1 world to another and it keeps breaking off

I think I ran into something like that when I was trying to generate some custom structures in-game. When there is world-gen happening, I don't think neighbors notify, but during the game they usually do.

 

In 1.7.10 I think you can stop the notification with the "flag" parameter passed to the World#setBlock() method. The comment for that method says:

    * 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.

 

So I think you would use flag = 2. This won't update neighbors but will still update the client.

 

I'm not sure how to do this in 1.8, as the World#setBlockState() method doesn't seem to have that flag anymore.

Just like in 1.7.10, there's an overload of

setBlockState

with and without the

flags

argument.

That makes sense. Thanks for the confirmation.
