How do you find out the player UUID?

The Minecraft Wiki says the following: A UUID consists of a 16-byte number that is noted in hexadecimal and divided into five groups.

But if I go to this page: https://www.gamergeeks.nz/apps/minecraft/mob-generator/summon-cat

Then it says at Owner: The UUID of the player that tamed the horse, stored as four ints.

As far as I know, four means 4 and not 5. How do I get this Strange Player UUID out to spawn a cat?

Just go to mcstacker.net and see what you can do there

and the player uuid you get out on namemc

An Int has 4 bytes, so 4 Ints together have 16 bytes. The UUUD is a 16-byte number. So fits as you see. It is only visually divided into 5 parts - it is saved as 4 ints (= integers).

You can get a player's UUID on sites like https://de.namemc.com/. Simply enter the player name and the UUID will be displayed.

Yes, but on namemc you only get a combination of numbers that is divided into 5 parts

Yes, just enter the 5 part on the website

try it

But there are 4 fields on the website… Strange stuff

Then use mcstacker.net

do you people not understand that UUID is a 5 part code?! Yet the commands on all the site you mentioned also requires a 4 digit code… HOW do you tranlate the UUID code for a player from the 5 part code to the 4 part code the command requires
