Sign Bug? about scaffolding

[LooFifteen]

You need to set the block handler of the signs when they are placed by scaffolding. This project is currently stale so I will not be adding any features to make this task easier.

// Registering the SignHandler
MinecraftServer.getBlockManager().registerHandler(NamespaceID.from("minecraft:sign"), SignHandler::new);

// SignHandler Class
public final class SignHandler implements BlockHandler {

  @Override
  public @NotNull NamespaceID getNamespaceId() {
    return NamespaceID.from("minecraft", "sign");
  }

  public Collection<Tag<?>> getBlockEntityTags() {
    return Arrays.asList(
        Tag.Byte("GlowingText"),
        Tag.String("Color"),
        Tag.String("Text1"),
        Tag.String("Text2"),
        Tag.String("Text3"),
        Tag.String("Text4"));
  }
}

What do you mean with when they are placed by scaffolding?
I have registered the SignHandler already.

You need to set the block handler when the block is placed. Just registering it does not apply it to the sign.

Block block =
                    Block.OAK_SIGN
                        .withTag(
                            Tag.String("Text1"),
                            GsonComponentSerializer.gson().serialize(Component.text("Line 1")))
                        .withHandler(new SignHandler());

                // Option 1
                AbsoluteBlockBatch absoluteBlockBatch = new AbsoluteBlockBatch();
                absoluteBlockBatch.setBlock(world.getSpawnPos(), block);
                absoluteBlockBatch.apply(instance, () -> {});

                // Option 2
                instance.setBlock(world.getSpawnPos(), block);

But this works for example. Just the Schematic Class does not seem to load it correctly. Have you tested it in the past with Signs?

I can't find a way of how to assign Handler after they are placed by the BlockBatch you apply with the Schematics. There maybe need to be a PreSetter Parameter to change the Block before it gets applied to the BlockBatch
