Scoreboard

The scoreboard system is a complex gameplay mechanic utilized through commands. Mainly intended for mapmakers and server operators, scoreboards are used to track, set, and list the scores of entities in a myriad of different ways.

An objective tracks a score for entities while meeting a single criterion. These scores are stored as 32-bit integer ranging from -231 to 231-1.[a]

Objectives have two main properties: a name and a criterion. The objectives' name is used internally for referencing in commands, target arguments, and the file format, while the criterion determines the objectives' behavior – primarily what to track.
