Errors with Fabric Generator and certain Procedure Blocks
Mon, 12/08/2025 - 18:19 (edited)

So I'm trying to use MCreator to make a Fabric mod for version 1.21.8, using the Fabric Generator plugin for MCreator. One of the things I'm trying to make is a custom block entity with a crafting interface, but whenever I try to save the procedure involved in crafting (for which I modified one of MCreator's procedure templates), I get a slew of errors, such as:

  • "Block block_nbt_num_get is not supported by the selected generator!"
  • "Block block_inv_get_item_inslot is not supported by the selected generator!"
  • "Block block_inv_get_amount_inslot is not supported by the selected generator!"
  • "Block block_nbt_num_set is not supported by the selected generator. It will be skipped."
  • "Block block_inv_remove_items is not supported by the selected generator. It will be skipped."
  • "Block block_inv_set_items is not supported by the selected generator. It will be skipped."

These errors in particular seem strange to me; according to the plugin's Github page, these kinds of block inventory procedures had been implemented just over 3 years ago: (link). If block_inv procedures have been implemented for all this time, then I have no idea why I'm getting errors for them.

There's also the matter of the block_nbt procedures, and I couldn't find any issues posted on the aforementioned Github mentioning block_nbt procedures in particular.

If anyone knows something that could help, please tell me!
