Scheduler Systems

Scheduler Systems

Systems run through Scheduler.addSystem(stage, system, order?).

System Contract

const system = {
  id: 'example.system',
  stage: 'Update',
  order: 100,
  reads: [],
  writes: [],
  runIf(world) {
    return true
  },
  execute(ctx) {}
}

Context

execute(ctx) receives:

• world
• deltaTime
• commands
• events
• resources

Lifecycle Control

• run() starts stepping behavior
• pause()/resume() gate stepping
• shutdown() runs shutdown stage and stops scheduler

Utility Types

• Profiler for runtime timings
• SeededRng for deterministic randomness
• DeterminismValidator for risk checks
