I looked all around for a radius tag in 1.13 snapshot and couldn't find a thing about it, someone plz help
The radius target selector variable has been renamed to distance and now supports doubles and ranges.
It'll now go like this:
Will test for between 5.9 and 15 blocks away
Don't forget that you can leave one of the values out. So: distance=..20 will test for a maximum distance of 20.
Kind regards, Peter
