[Tip] Coroutine Optimization Technique

Optimization Technique :

Let’s take an example, and see why and where we can optimise. Below  Coroutine just waits for the 0.5 sec and then call your desired method.

?

1 2 3 4 5 6 7 8 9

IEnumerator WaitCoroutine()   {   yield return new WaitForSeconds(0.5f);   // Call your Method here   }

 

But every time you call this method “new WaitForSeconds(0.5f)” will allocate memory for the new object, which is not good.

Instead, we should save its reference in Start, and use it when it is required, In this way, we will not allocate memory on every call.

?

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15

WaitForSeconds wait;   void Start() {   wait = new WaitForSeconds(0.5f); }    IEnumerator WaitCoroutine() {       yield return wait;   // Call your Method here   }

Never use “yield return 0“, instead of that use “yield return null”
