Coroutines • Performance

More Effective Coroutines

Coroutines that run about twice as fast as Unity's, with zero per-frame allocations, and a pile of functionality Unity never gave you. Run them anywhere with no MonoBehaviour, control them by tag, layer, or handle, chain and delay them, and reach into extra timing segments when you need them.

// MEC: runs anywhere, no MonoBehaviour
Timing.RunCoroutine(_CheckForWin());
Timing.RunCoroutine(_Tick(), Segment.SlowUpdate);

Built to drop in

Same structure. More power.

MEC keeps Unity's familiar yield-return shape, so switching over is mostly find-and-replace. Add two using statements, swap StartCoroutine for Timing.RunCoroutine, and you immediately get a central runner that does not stop just because a GameObject was disabled or destroyed.

using System.Collections.Generic;
using MEC;

private IEnumerator<float> _CheckForWin()
{
    while (_cubesHit < TotalCubes)
        yield return Timing.WaitForOneFrame;
    WinText.text = "You win!";
}

Why developers switch

Coroutines that pull their weight.

∞

Zero per-frame allocations

No garbage generated each frame, and the infrastructure runs about twice as fast as Unity's. Rock solid under load.

☉

Run anywhere

No MonoBehaviour required. One central runner means coroutines keep going even when an object is disabled or destroyed, unless you choose otherwise with CancelWith.

☷

Timing segments

Update, FixedUpdate, LateUpdate, and SlowUpdate out of the box. Pro adds Realtime, End-of-Frame, Late-Fixed, and Manual.

Tags, layers, handles

Identify coroutines individually or in groups, then pause, resume, or kill them in a single call. Move one to a different segment on the fly.

⏱

Helpers built in

CallDelayed, CallPeriodically, CallContinuously, and WaitUntilDone cover the patterns you reach for constantly, without writing a coroutine for each.

❖

Pro power tools

Singletons, Delay, Append and Prepend, Superimpose, Hijack, handle properties, and OnDestroy callbacks for full control.
