Minecraft:Advancements

• Changed and moved around many existing advancements:
  • "Withering Heights" is now an offspring of "Spooky Scary Skeleton".

  • "Remote Getaway" is now an offspring of "Free the End", and works properly when player throws an ender pearl into the Minecraft:gateway.
  • "Sky's the Limit" is now an offspring of "City at the End of the Game", and is now a "goal" type advancement.
  • "Zombie Doctor" and "Eye Spy" are now offspring of "We Need to Go Deeper".
  • "Eye Spy" now requires the player to enter the Minecraft:stronghold.
  • "A Weak Brew" was replaced with "Local Brewery" (nether/brew_potion), which is an offspring of "Into Fire" and requires the player to retrieve any potion from a Minecraft:brewing stand.
  • Illusioner now counts for "Monster Hunter" and is required for "Monsters Hunted", which makes the advancement unobtainable.
  • "Sniper Duel" not requires a skeleton to be killed.
• Advancements can now execute commands when achieved.
  • The command written in the rewards section of the advancement is executed as the player (for example writing /say @s would be equivalent to /execute <the_player_who_obtained_this_advancement> ~ ~ ~ say @s)

    • Within it are a required item string (specifying the item ID) and an optional data integer, specifying the metadata of the item
