RS785

Thank you I'll have a look at it right now.

I must serialize the NBTList into a String and then write it into a file. How could I use NBT to save a file to a specified path? I'd like to save the entire player class (position, inventory, effects, et cetera) for each dimensions.

I'm now facing an issue when serializing and deserializing, I better know how NBT works but when using Gson I can only serialize to a file which looks like this: {"mainInventory":[{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}}],"armorSlots":[{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}},{"tagMap":{"id":{"data":"minecraft:air"},"Count":{"data":1}}}]} But when it comes to deserialization, Gson doesn't work... I won't upload the full log but important bits I cannot understand: [11:32:13.645] [Server thread/ERROR] [EventBus/EVENTBUS]: Exception caught during firing event: Unable to invoke no-args constructor for interface net.minecraft.nbt.INBT. Register an InstanceCreator with Gson for this type may fix this problem.

I’m using MCP mappings. build.gradle file —> channel: snapshot | version: 20201028-1.16.3

Could you please send me some examples. I'm having a rough time trying to get it working. I don't know why but I don't have: PlayerInventory#save(ListNBT) nor PlayerInventory#load(ListNBT) But instead: #write(CompoundNBT) and #read(CompoundNBT)

What is ListNBT and how shall I declare it?

Hello, I'd like to serialize and deserialize players' inventories in order to have 1 inventory per dimension (Overworld, nether, end, my_custom_dimension). I currently have the PlayerEvent.PlayerChangedDimensionEvent event set-up and the custom dimension, I don't know how could I serialize & deserialize the inventories. I've already tried Gson without any success, it kept on crashing. Thank you in advance for the help @SubscribeEvent public static void onPlayerChangeDimension(PlayerEvent.PlayerChangedDimensionEvent event) { PlayerEntity p = event.getPlayer(); RegistryKey<World> from = event.getFrom(); RegistryKey<World> to = event.getTo(); // Save the player's inventory (from) // . . . // Retrieve the player's inventory (to) // . . . }
