Flags set by the core software use the "core" scope. Flags set by game systems or modules should use the canonical name attribute for the module Flags set by an individual world should "world" as the scope.

Flag values can assume almost any data type. Setting a flag value to null will delete that flag.

The flag value

A Promise resolving to the updated Entity
