Custom WaitForXXX classes?

Unity Engine
1

Is it possible to write myself WaitForXXX classes, use in coroutine to wait for events not provided by unity?
Any examples?

WaitForSeconds would be implemented like this:

function MyWaitForSeconds (waitTime : float) {
	var timer = 0.0;
	while (timer <= waitTime) {
		yield;
		timer += Time.deltaTime;
	} 
}

Obviously there’s no point actually using that since WaitForSeconds exists, but you can use that as a template and modify it for whatever you need.

Thx, simple but not an efficient design, though,especially when massive WaitForXXXs are pending.I thought it was an event-based way previously.

And what about the class form? In c#, I must write
yield return new WaitForSeconds(1.0);
WaitForSeconds is a class that inherits from YieldInstruction. Can I write a class implements YieldInstruction?

Hi Cometeor,

Please look at Coroutine Manager on the asset store. It is open source so you can easily add your own WaitForXXX. See that CoroutineManager.WaitForSeconds() is provided as an example.

As I am continuously trying to improve Coroutine Manager, please let me know what features you need.

Hope this helps.
