Per request made a small change to not spawn any mobs (besides the dragon of course) in any difficulty on the game worlds.
Added a new Scoreboard system for Dragon Escape
True by default, to go back to the old scoreboard set Options.Use-New-Dragon-Escape-Scoreboard to false.
Change the Scoreboard at Scoreboard.Dragon-Escape-Scoreboard-Format
Change the text for when the position is empty at Leaderboard.Messages.No-Scoreboard-Position
Note that the player name will be green if he is alive and red if he is dead.
You can add how many positions you want to the Scoreboard
Other placeholders are:
%wins%, %games_played%, %balance%, %spectators%
%players% - returns all player count (alive and spectators)
%position% - returns the position of the player
Didn't get to fully test out! Please report any problems at discussion and/or Private Message and if anything is wrong you can go back to the old scoreboard system until the problem gets fixed.
