getGameLevelsSchema¶

Overview¶

Gets the QueryStringMachine schema for the gameLevels query parameter. Note that game levels are numbered starting from 1.

History: - The gameLevels query parameter was first proposed and discussed in https://github.com/phetsims/vegas/issues/86. - The design of the gameLevels query parameter was solidified, and it was first implemented in Equality Explorer, see https://github.com/phetsims/equality-explorer/issues/165. - When gameLevels was needed in Fourier, the schema was then copied from Fourier to Equality Explorer, see https://github.com/phetsims/fourier-making-waves/issues/145. - During code review of Number Play in https://github.com/phetsims/number-play/issues/92, yet-another implementation was discovered. That motivated factoring out this function, to prevent further duplication and inconsistency.
