Posted July 15, 20232 yr How could I save/load an arraylist variable and attach it to the map/world? And if I was to serialize the arraylists into a file, where would I put it? Can I use SavedData with lists? I'm quite a beginner, but I did some digging and didn't find a solution yet, any help would be greatly appreciated. Edited July 15, 20232 yr by Vortek
July 16, 20232 yr https://forge.gemwire.uk/wiki/Saved_Data just make one method (save) that stores your thing into CompoundNBT and another (constructor in 1.18+, separate load method in 1.16) that rebuilds your list/map/whatever from NBT. you can attach everything to overworld (unless the world is part of your data in which case split and attach separate data to each world).
