Topic category: Help with modding (Java Edition)
So, I'm working on a mod that is just for fun and I want it so that if you get an item you should get an advancement. This should be really easy, but the game crashes whenever I should get the advancement, saying something about Player Ticks.
Here is the crash log:

And these are some photos of the code:
The second one is what I have been struggling with for a long time that also uses player ticks, and it is supposed to give buffs if the player wears OP armor and also a different advancement (see picture 3).
Can anybody tell me what's going on and how I can fix it?
Thanks!
In the newest mcreator version, there is a bug with advancedments which changed how they’re made.
You need to deselect all advancement procedure blocks and reselect them
Ok, but how will that fix the player ticks?
I did that, and it may be unrelated but my game crashed immediately (for the ticking player reason it said) instead of when I got the trigger item (an ore drop)
I tried again and it said it crashed due to server tick loop as soon as I made a new world. I don't know if this helps, I'm just trying to give all the info. Thanks for helping
then open a ticket on the issue tracker I think
OK
