Hi, I am trying to write a custom command that finds specific blocks (with certain blockstates) and replaces them with other blocks with specific blockstates. I tried capturing a blockstate like this:

BlockState sourceblock = Blocks.RED_GLAZED_TERRACOTTA.getDefaultState().with(BlockStateProperties.FACING, Direction.NORTH);

and it crashes. What am I doing wrong? BTW: If I do it without the ".with(BlockStateProperties.FACING, Direction.NORTH)" part it works but then I can't get a specific blockstate. I don't want to replace all of a particular block, just all of a particular blockstate, like all red_glazed_terracotta[facing=north]. I also need to make sure I can build a similar blockstate for the destination block to replace with.

In 1.12.2 I did it like this: BlockState sourceblock = convertArgToBlockState(Blocks.RED_GLAZED_TERRACOTTA, "0")

The reason I want a blockstate is that I can do world.getBlockState(tempBlockPos) followed by a if check then a world.setBlockState(tempBlockPos, replaceItem.newBlockState, 2);

 

Am I doing something wrong with my BlockState? Is there a better way to do this (without resorting to typing in the fill command)?

Thank you for any help.

What's the message?

Sorry, I should have been more clear. The game doesn't crash, the command dies midway through. I added logger commands and can tell that it stops functioning at the exact statement above. I also get "An unexpected error occurred trying to execute that command" in the chat window and in the log.

Never mind, I figured it out. That particular block doesn't have a FACING property, it has a HORIZONTAL_FACING property. Use the right one and the code works.

Tada, magic. Always use the right properties.

 

And for the record, it was throwing an error, you just couldn't see it.

Is there a place I could see the error? It didn't show up in the debug log.

Unclear, as because you were piping things through commands, it probably got quashed.
