Scoreboard

The scoreboard system is a complex gameplay mechanic intended mostly for map makers. It is used via commands and command blocks.

Objectives
Objectives are a combination of a name, a display name, and a criterion, and track an integer number of points for players. The full score range is -2,147,483,648 to 2,147,483,647, and only supports integers.

An objective's name is used internally when referenced in commands, target arguments, and in the file format. It is case-sensitive and must be a single word.

Conversely, the display name can be multiple words, and is displayed publicly in various situations. It is also case-sensitive, and does not have to be unique.

An objective's criterion determines its behavior:

Some criteria use the Statistics and Achievements systems to form compound criteria. Unlike the simple criteria above, compound criteria have multiple parts, separated by periods ("."). For example, "stat.entityKilledBy.Zombie" would be a compound criterion, which would increment for a player whenever a zombie kills them.

A list of known compound criteria follows:
