I would never have figured this out on my own, changing the function folder name, or it would have taken a really long time and annoying googling, thank you!

[@BurntOutGamer]

Glad I could help!

[@lefantastique59]

I had the same problem and I was losing my mind! Every other sources I've seen told me to name it "functions"

[@BurntOutGamer]

@@lefantastique59 yeah the problem is there’s so many more tutorials about the old datapack system that when you look up how to fix it in the new system it’s hard to find the answers you’re looking for.

[@craftyblue8576]

Thanks for pointing out the "function" thing, they also changed some things with the dust particle, it was previously: /particle dust 3.0 3.0 3.0 2.0 ~ ~1 ~ 0 0.3 0 5 1 normal /particle dust_color_transition 0.33 0.33 1.0 1.0 1.0 0.33 0.33 ~ ~ ~ 1.8 0 1.8 0 20 force and now it's /particle dust{scale:2.0,color:[3.0,3.0,3.0]} ~ ~1 ~ 0 0.3 0 5 1 normal /particle dust_color_transition{scale:1.0,from_color:[0.33,0.33,1.0],to_color:[1.0,0.33,0.33]} ~ ~ ~ 1.8 0 1.8 0 20 force

[@BurntOutGamer]

Cool! I haven’t done anything with the dust particle yet so that is good info, thank you!

[@forgotten7008]

Wow, did so much googling and the issue was just changing the folder name from functions to function. Thank you so much ❤

[@BurntOutGamer]

It’s so funny, I think I only found this out by finding someone’s 1.21 snapshot datapack and downloading it to see what was wrong with mine.

[@mutantfrogs]

omfg same XD, I was going INSANE!!!

[@EnorIII]

3:29 Thank you so much! I've been trying to figure out why nothing was working for the past 2 hours. That was it xD

[@BurntOutGamer]

Glad I could help!

[@jboy6553]

Thank you so much man! that "functions" to "function" thing tripped me up, nothing was working or even showing up in game and had me really scared

[@BurntOutGamer]

Glad I could help!

[@Space_US]

thank you SO much for the function thing. I had a purley advancement/loot table datapack and was pulling my hair out tryna make it work

[@BurntOutGamer]

Glad I could help!

[@ThoreWagner]

Thank you very much 😀

[@BurntOutGamer]

Glad I could help!

[@batcat3660]

Yay! MOAR CONTENT

[@BurntOutGamer]

Wooooo!!

[@EricIsntSmart]

Desperately need someone to make a datapack syntax visualiser for VScode that is up to date for 1.21

[@BurntOutGamer]

That would definitely be nice. For now I’m just using command blocks in game to check my work.

[@Toolo559]

Bruh now I need to update over 100 item desings to my custom map to have it on the latest version. ;_;

[@Toolo559]

thx for the video tho, I will need this information again and again and again..

[@BurntOutGamer]

@@Toolo559 sorry about that! I’m working on a custom map as well. Let me know if you have any questions and make sure you subscribe if you haven’t already. I’ll be making a lot more videos about the changes and my discoveries with the new stuff they added.

[@patty4449]

Wait till you get into making custom enchantments... Im losin my sh*t figuring out how the new stuff works... They changed some stuff between last snapshot and 1.21 which also broke ALL enchantment datapacks that focus on attributes btw... Name and UUID are now gone from attributes and replaced with "id:" but idfk what to put after that tbh, the example datapack doesn't even work with a fresh datapack in format 48 etc...

[@BurntOutGamer]

I actually made videos on both of these! I made potion swords with custom enchantments and a lot of different types of attribute armor. Check out my channel!

[@Siam070]

After changing functions to function, every mcfunction file is red and there is no more connection shown between tick.json and tick.mcfunction...

[@BurntOutGamer]

Did you change functions to function in the Minecraft folder as well as your namespace folder?

[@Siam070]

@@BurntOutGamer yeah, changed both of them. Found out that everything works normally even though every file has at least one error at the first character in the first line (maybe it has something to do with vscode?)

[@BurntOutGamer]

@@Siam070 ah I see what this is. The datapack helper plug-in is what is giving you these “errors.” It doesn’t understand the new system yet as it hasn’t been updated

[@nodezeroo]

If you don't mind me asking. What extensions for VC for MC are you using? The one I'm using keeps telling me my pack is wrong.

[@BurntOutGamer]

I turned off datapack helper plus because it’s not updated to the new command system yet. Other than that I think I have one called Minecraft commands. I’ll double check in an hour or so

[@BurntOutGamer]

ok I just double checked and the extensions I have are language-mcfunction and syntax-mcfunction

[@nodezeroo]

@@BurntOutGamer ty so much

[@newkamil3757]

Is there any way to get rid of the red underline in vscode?

[@BurntOutGamer]

That comes from the datapack helper plug-in not being updated for 1.21 yet. So you could disable that add on and it would get rid of that :)
