Test for only for me
If my Name is Bence on the server, how can i check only for me?
example: /testforBence[x=82,y=64,z=271,r=2]
I have this error: The entered UUID is invalid Format.
Selector arguments can only be used with selectors (@p, @e, @a, @r).
You should use a selector, then use the name= selector argument to target only people with the name "Bence":
/testfor @a[name=Bence,x=82,y=64,z=271,r=2]
