You have to delete/update the config to run this version (changes below)! Leave a 5⭐ review if you want to support and motivate me! Changelog:
As you requested, added the option to set a custom knockback for each world (read new config for documentation). Talking about custom regions, i'm finding a good way to detect the current region where the player is in without causing any kind of delay due to computation of coordinates (it will be released shortly).
Improved the performance by almost 10%, now the knockback is calculated in a bunch of microseconds (1 microsecond = 0.000001 second).
Fixed minor setbacks with NoCheatPlus in 1.13 servers.
