A simple but powerful Scheduler implementation in UnityEngine.

Provides methods for registering per-frame updates(Update/LateUpdate/FixedUpdate):

int updateCount = 0;
Scheduler.ScheduleUpdate(() => Debug.Log($"{++updateCount}"));

int lateUpdateCount = 0;
Scheduler.ScheduleLateUpdate(() => Debug.Log($"{++lateUpdateCount}"));

int fixedUpdateCount = 0;
Scheduler.ScheduleFixedUpdate(() => Debug.Log($"{++fixedUpdateCount}"));

And registering scheduling tasks for delayed or specified interval updates:

Scheduler.Delay(() => Debug.Log("Delay"));

Scheduler.ScheduleOnce(() => Debug.Log("Once"), 0.2f);

Scheduler.Schedule(() => Debug.Log("Every 0.1s and 10 times"), 10, 0.1f);

var scheduledTask = Scheduler.Schedule(() => Debug.Log("Every 0.1s"), 0.1f);
Scheduler.Unschedule(scheduledTask);

Scheduler.ScheduleWithDelay(() => Debug.Log("Every 0.1s after 2s"), 0.1f, 2);

Scheduler.ScheduleUnscaled(() => Debug.Log("Every 0.1s ignoring timescale"), 0.1f);

A proper schedule mode leads to better runtime performance. When trying to create a scheduled task there are three modes to select, Dynamic, Static, and LongTerm.

• ScheduleMode.Dynamic: for short lifespan tasks and intended to be created/deleted frequently.

• ScheduleMode.Static: for tasks that exist long lifespans and are NOT created/deleted frequently.

• ScheduleMode.LongTerm: for tasks are executed at very long intervals and are NOT intended to be created/deleted frequently.

Schedule mode can be explicitly assigned, like this:

Scheduler.Schedule(() => Debug.Log("Every 0.1s and 10 times"), ScheduleMode.Dynamic, 10, 0.1f);
Scheduler.Schedule(() => Debug.Log("Every 0.1s"), ScheduleMode.Static, 0.1f);
Scheduler.Schedule(() => Debug.Log("Every 1h and 3 times"), ScheduleMode.LongTerm, 3, 3600f);

Otherwise, the Scheduler.defaultScheduleMode will be used, which has an initial value ScheduleMode.Dynamic. You can change the default schedule mode by modifying this property.

And shortcut methods for thread synchronization context:

// register in any thread and get realtimeSinceStartup in Unity main thread:

Scheduler.Send(() => Debug.Log($"{Time.realtimeSinceStartup}"));
Scheduler.Post(() => Debug.Log($"{Time.realtimeSinceStartup}"));
