Datapacks not working anymore

[worldly peak]

I made some fun and fully working 1.21 Snapshot Datapacks a while back, already using the new nbt structure style.
It was made for 24w11a and there It all worked perfectly fine, after Updating them to 1.21 nothing worked anymore, anyone got an easy way to fix this? What Changed?

read the full changelog for 1.21

without anything specific about your format we cannot help

I simply cannot remember if 24w11a had the folder changes or not, you're better off reading through

[leaden thicket]

You probably didn't catch the folder name changes. Most data pack folder names changed to be singular rather than plural (functions is now function, etc.) the exception is tags is still tags, but it's subfolders are now also singular (tags/functions is now tags/function, etc.)

Remember to make these changes in your minecraft namespace as well as your own

And then after that, if you're using attributes basically anywhere, a lot of that syntax has changed. There was also a minor change to recipes

This is the full list of directory renames

Those I'd say are the big 3

All the other changes for 1.21 are here if you need them

thanks

Ill look into that

[worldly peak]

If you go to the advancement tab, do I have to change recipes to recipe or does it stay the same there?

[leaden thicket]

advancement/recipes is just for organization, it's not a functional folder like the tags subfolders are, so you should be good to keep it the same

it seems to work again now thank you guys, just one quick question,
Why is it that if I modify a crossbow with having more Projectiles now, that If I put 3 as regular when you have multishot they all shoot at the same spot more like a burst but when I add more arrows (for example up to eight) they spread more than the field of fiew. Was there something new added to specify the spacing of the loaded arrows inside a crossbow?

[leaden thicket]

It could be due to the data-driven enchantments change, I see that Multishot has an effect for both projectile count as well as projectile spread. How are you adding additional projectiles currently?

[worldly peak]

thanks a lot, It was due to the Multishot level I have, that was a new change too
