Child 'set_block_property' not valid here!

[meager pivot]

Hi! I'm diving in by trying to fix up a cooking addon on 1.20.41, https://mcpedl.com/creative-cooking-addon-1/

Many of the crop blocks don't work because of a "set_block_property" element being placed wrongly somehow, but I can't work out why. Are there any rules I don't know about where this can be used?

This use turns up as invalid, giving the error /behavior_packs/creative_cooking_bp | blocks/corn_stalk.json | creativecooking:corn_stalk | events | grow_stage | set_block_property | child 'set_block_property' not valid here.

    "events": {
      "grow_stage": {
        "randomize": [
          {
            "weight": 4
          },
          {
            "weight": 1,
            "sequence": [
              {
                "condition": "query.block_property('creativecooking:growth_stage') < 3",
                "set_block_property": {
                  "creativecooking:growth_stage": "query.block_property('creativecooking:growth_stage') + 1"
                }
              },
              ...etc...

However, other blocks use similar JSON in their events and don't throw up errors. For example, the definition for a wheat thatch slab, the events block is:

            "place": {
                "sequence": [
                    {
                        "condition": "query.head_x_rotation(0) <= 0",
                        "set_block_property": {
                            "creativecooking:slab_type": 1
                        }
                    },
                    {
                        "condition": "query.head_x_rotation(0) > 0",
                        "set_block_property": {
                            "creativecooking:slab_type": 0
                        }
                    }
                ]
            }
        }```

Removing the "randomize" element and just putting the "sequence" directly under the event name works, but I'm not sure why - is set_block_property somehow disallowed in an action that's part of a randomize?

No, it still works with randomize, perhaps the block's format_version no longer accepts set_block_property, so you would have to use set_block_state

Aha, that could be it - I was just looking at https://wiki.bedrock.dev/blocks/custom-crops.html and saw that it was using "set_block_state". Thanks

Is there a good place to look up deprecations/changes like this? There seem to have been a million different versions 🙂
