Edit: I made one of them work, before it wasnt working, do you have to "enable" the commands?
Example: /execute as @p at @s unless block ^^^-1 air run kill @s
9/10 (fills the tag/score list 💀)
Yes, I enabled Beta APIs. Yes, I turned on cheats etc. And yes, it is the highest priority script/BP (at the top of the list). I don't have any of the scoreboards or tag functionalities. Please let me know, somebody, if there is a command or setup I need to use beforehand so that I can fully use this script. Thank you. Three stars for now, since I admire the work that goes into these types of scripts regardless.
Edit: I managed to update to 1.20.72, so ignore the whole message before this. I rated it 5 stars. This works amazingly.
