Advancement Flags

Advancements can have additional information, or flags, to demonstrate special conditions for the advancement.

Advancement a1 = ...

Set<AFlag> flags = new HashSet<>();

// The advancement will display a toast message in the top-right corner of the screen demonstrating its completion.
// Added by Default
flags.add(AFlag.TOAST); 

// The advancement will hide itself and its children from the advancement screen until it is completed. Useful for 'secret advancements.'
flags.add(AFlag.HIDDEN);

// The advancement will broadcast a message to the console and all players showing your completion of the advancement.
// Added by Default
flags.add(AFlag.MESSAGE);

// If the advancement has multiple criteria, it will merge all of the criteria into one requirement, removing the criteria progress bar.
flags.add(AFlag.MERGE_CRITERIA);

a1.setFlags(flags);
