Bukkit

No Void Damage will prevent players from taking damage form the VOID. If players are falling into the void, they will get teleported to the highest block at their position, if possible, or the the worlds spawn location, if possible in a safe way. In addition if the player is actually not online (due to bugs) it will issue kicking and removing the player. Teleported players will not take fall damage the next time after teleporting.

This has been made because my players where falling into the void randomly on login , even after logout and we could not narrow down the cause.

Features (0.3.0):

• Prevent damage by the void for players, teleport to a safe location above or to the worlds spawn location, if possible. Prevents one time fall damage on teleporting.
• Log teleports.
• Exclude worlds by exact name or by a suffix. By default worlds ending on "_the_end" are excluded from checks.
• Configuration:
  If to log, which worlds to exclude.
• Reload command:
  novoiddamage reload
  needs: novoiddamage.reload or op.
