Change App.registerSystem

[waynemwashuma]

Objective

Refactor the system registration API to use a configuration object instead of positional arguments.

Solution

Changed App.registerSystem(schedule, system) to App.registerSystem({ schedule, system }).The previous signature limited flexibility (e.g. adding system groups, ordering metadata, labels, etc. in the future) and made the API less explicit.

This change makes the registration more readable and prepares the scheduling system for future enhancements.

Showcase

Before

app
  .registerSystem(AppSchedule.Startup, init)
  .registerSystem(AppSchedule.Update, setupViewport)
  .registerSystem(AppSchedule.Startup, addDefaultCamera2D)

After

app
  .registerSystem({ schedule: AppSchedule.Startup, system: init })
  .registerSystem({ schedule: AppSchedule.Update, system: setupViewport })
  .registerSystem({ schedule: AppSchedule.Startup, system: addDefaultCamera2D })

Migration Guide

This is a breaking change.

Replace all occurrences of:

.registerSystem(ScheduleLabel, systemFunction)

with:

.registerSystem({ schedule: ScheduleLabel, system: systemFunction })
