Simple question about UUIDs.

Ok, I'm currently working with UUIDs and I'm using SLAPI to save/load HashSet's into a .bin file.

I am testing by dropping a block at the ground, then trying to pick it up. If it's dropped by a player with spawn rights it will cancel the pickup event. It works perfectly, but after I've reloaded/restarted the server whilst the entity is still at the ground, it stops working. (I can pick it up).

So my question is, do entity UUIDs reset/change upon server restart/reload?
Or may it be me doing something wrong?

 

the UUID wont persists server restarts, but it should survive reloads

 

I've heard that uuids stay true after a reset

 

mollekake that is what I have been told as well

 

You mean they still applies for the same entity after a restart? Or?

 

I've confirmed it with part of the team, UUIDs are suppose to persist through server restarts.

 

He means something similar like saving UUIDs. If you stop the server and start it again, they would still point towards the same entities. (note, the saving UUIDs is an example, not the actual question)

 

yeah. uuid stays the same. entity id on the other hand change, and is quite a smaller number. the uuid is freaking long

 

Does EntityID (EID) work same way as UUID ?

 

Only if you plan to use the ID quickly and get rid of it. Since multiple entities can possibly have the same EID.
