This is my first data pack. During gameplay you start in a small worldborder but, as you walk, the worldborder moves with you.
sounds easy right?
It certainly isn't. And here's why:

1. Items can't be thrown through the worldborder so it's difficult to clean up inventory

2. You can't hit things outside the worldborder (mobs and blocks)

3. The worldborder lines can annoy you a little (very much).

Please leave feesback in the comments and I'll make datpack better.

THIS DATAPACK IS FOR SINGLEPLAYER NOT MULTIPLAYER!
