V3206. Unity Engine. A direct call to the coroutine-like method will not start it. Use the 'StartCoroutine' method instead.

The analyzer has detected a suspicious call to a coroutine-like method in a Unity script the return value of which isn't used. To start coroutine, use the 'StartCoroutine' method.

Take a look at an example:

class CustomComponent: MonoBehaviour
{
  IEnumerator ExampleCoroutine()
  {
    ....
    yield return null;
    ....
  }

  void Start()
  {
    ....
    ExampleCoroutine();
    ....
  }
}

In this case, the 'ExampleCoroutine' coroutine code is not executed because the 'IEnumerator' object returned as a result of the call is not used in any way. To fix the issue, pass it to the 'MonoBehaviour.StartCoroutine' method:

void Start()
{
  ....
  StartCoroutine(ExampleCoroutine());
  ....
}
