No Dirt Warfare!

This modification introduces an important limitation to Minecraft's PvP system. It blocks the ability to attack other players for characters who haven't set their respawn point using a bed or spawn point.

This feature is particularly useful on PvP servers where players, after losing all their items upon death, might continue attacking opponents without serious consequences. Now, to fully participate in battles, you must first secure a respawn point anywhere different from the world's default spawn. If your bed gets destroyed by an opponent, the PvP capability will be blocked until the moment of death.

Essentially, this implements the "new life" principle - every time you lose your respawn point, you temporarily exit combat until the next respawn.
