I've been looking through vanilla and I think this works.  Would someone confirm if I've got this right or if I'm missing stuff.

 

My goal is to put down a custom bed in place of the normal one so it doesn't blow up in my custom dimensions.

 

 

 

 

                    // Get current meta

                    IBlockState state = world.getBlockState(pos_Temp);

                   

                    // Change the block with the meta intact

                        world.getBlockState(pos_Temp).withProperty(BlockBed.PART, state.getValue(BlockBed.PART)).withProperty(BlockDirectional.FACING, state.getValue(BlockDirectional.FACING));

Looking at the bed in 1.8, I see another way around this in terms of avoiding the explosion.

 

However, I still would like to know about the state copy I put above.

I think you should use World#setBlockState(...)

Just noticed some of my code was wrapped weird in the post.  might be hard to read.

 

If I setBlockState, that sets the entire block again.  I just want to modify a few of the state properties and leave the rest alone.

Then there is no way theoretically...

IBlockState

s are immutable.

IBlockState#withProperty

returns a different

IBlockState

instance with the property set to the specified value rather than modifying the existing instance.

 

If you want to change the state of a block in the world, you have to use

World#setBlockState

. Simply calling

IBlockState#withProperty

and not doing anything with the result does nothing.

 

Your code will correctly preserve any properties except the ones you change, though.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

    • Version 1.19 - Forge 41.0.63 I want to create a wolf entity that I can ride, so far it seems to be working, but the problem is that when I get on the wolf, I can’t control it. I then discovered that the issue is that the server doesn’t detect that I’m riding the wolf, so I’m struggling with synchronization. However, it seems to not be working properly. As I understand it, the server receives the packet but doesn’t register it correctly. I’m a bit new to Java, and I’ll try to provide all the relevant code and prints *The comments and prints are translated by chatgpt since they were originally in Spanish* Thank you very much in advance No player is mounted, or the passenger is not a player.
