[Solved] Trying to store and release mobs via custom item causes addEntityUuid to throw a warning.


Recommended Posts

I'm trying to store mobs inside an item using compounds. To write the mob into compound I use:


When all data is stored in the item I use this to discard it.


The compound also stores the mobs resource location and I use this to spawn and set the data:

// Resource location stored in entity tag.
EntityType<?> type = ForgeRegistries.ENTITIES.getValue(new ResourceLocation(stack.getOrCreateTag().getString("entity")));

// I use this to get the entity. I'm using 'MobSpawnType.BUCKET' which may not be correct, if so please inform me what else to use.
Entity entity = type.spawn(level, stack, null, pos, MobSpawnType.BUCKET, true, false);

// Adding data.

// Spawning

When spawning the logger outputs for example: 

UUID of added entity already exists: Horse['Horse'/128, l='ServerLevel[Test World]', x=-93.50, y=72.00, z=52.50]

And the UUID always increments with 2 so if I summon it again it would say 'Horse'/130, 'Horse'/132, 'Horse'/134 etc.

How can I prevent this?
