FAQ:

Q: How to protect an area? A: With one command that you can find below. It will claim a 30 blocks radius area, and you can use the command as much as you want for each 30 blocks radius you want to claim! It can also easily be unclaimed.

Q: How does the protection work, what does it protect? A: Once entering a protected area, mobs with griefable abilities will be killed (creeper, ravager, enderman, ender dragon, wither, phantom, warden) along with their loots. TNT & minecart tnt are disabled in a protected area.

Armor stands, item frames & glowing item frames, painting, are automatically set to invincible in a protected area. They are switching back to destroyable once the area get unclaimed. Q: Will the datapack change something in my world if I install it? A: It will only change the gamerule sendCommandFeedback to false to prevent the spam of the gamemode change message in the chat. Nothing else is changed

Q: If I uninstall the datapack, will the protections be gone? A: Yes, but they will be saved in case you reinstall the datapack later, unless you run /function area_protection:reset_all.

Q: If I use this as a mod in singleplayer and then upload the world on my server, will the areas I protected still be protected? A: No, unless you install the datapack or the mod on the server!

The datapack only uses tags, not teams, so if your world has teams enabled, the datapack is compatible with it.
