The title was going to be a bit more verbose, but I'd imagine that'd drive some people away even though for _somebody else_ with moderate data pack experience, this would be such a simple solve.

I put Food Healing for 1.20.x into a world for 1.20.5 and updated the datapack through Easy Map Updater, which made the pack function in an already-existing world after updating the save for 1.21.1 (which it says 1.21.5, but it always assumes latest and there isn't significant difference in any of the 1.21 branch).

When trying to use the datapack in a new world for 1.21.1, after dropping it into the datapacks directory for the world, it doesn't work as expected ­— this is because the pack's load function uses scoreboard commands, but it doesn't do anything to write that data into the world's scoreboard.dat file.

People tell me to create objectives and make constants, but I get all dizzy-face when something isn't basically done for me and I've never bothered with this fuss before. I assumed Easy Map Updater would fix scoreboard stuff for me, but I suppose it was a bit much expecting a utility for updating worlds to re-write data packs using the scoreboard function when there is _zero_ context for it, and I don't feel like asking an LLM to do this for me since I already waste enough water as it is myself, let alone somebody else's computer several hundred miles away from my location.

Here's the scoreboard writes it attempts to do, which works in 1.20.x but doesn't in 1.21.x:

gamerule naturalRegeneration false

scoreboard objectives add food_level food {text:"Food Level",color:"blue",type:"text"}
scoreboard objectives add sleep_reg minecraft.custom:minecraft.sleep_in_bed

effect give @s minecraft:saturation 80 0 true
effect give @s minecraft:hunger 10 150 true
So uh… how do I edit load.mcfunction to write the relevant scoreboard data into scoreboard.dat?
