Question by zikzakeroo · Apr 03, 2019 at 09:12 AM · coroutineyieldgetmousebuttondown

How do i use a coroutine to wait for 1 left mouse button click?

So I am trying to execute some code within a coroutine, then have it yield return and wait for left mouse click. Currently i am trying to do this by having another coroutine that waits for the mouse click that is called on a yield return. Something like this:

       IEnumerator Example()
             {
                 Debug.Log("Doing x")
                 yield return StartCoroutine(WaitForLeftClick());
                 Debug.Log("Doing Y")
             }
     
     IEnumerator WaitForLeftClick()
         {
             while (!Input.GetMouseButtonDown(0))
             {
                     yield return null;
             }
             Debug.Log("lmb clicked");
         }
 

I only want it to wait for 1 click but this outputs "lmb clicked" twice and in doing so executes the rest of the Example() coroutine twice. Is there a way to amend so it doesn't execute twice, or is there a different better way to do this? Any help would be appreciated, thanks.

Is "Doing x" only printed once?
