Coroutine couldn't be started

[Romeno]

I’m creating GameObject and adding MonoBehaviour to it.

go = new GameObject("sprite" + creepId);
mb = go.AddComponent<MonoBehaviour>();

Then I’m using mb to start coroutine

mb.StartCoroutine("coMove", new MoveData(Utils.ToVector2(go.transform.position), destPositions));

At run time I get Exception:

Coroutine 'coMove' couldn't be started!
UnityEngine.MonoBehaviour:StartCoroutine(String, Object)
JATD.Creep`1:Move(Vector2[]) (at Assets/JATD/Scripts/Creep.cs:68)
<Spawner>c__Iterator2:MoveNext() (at Assets/JATD/Scripts/MainGame.cs:103)

Any thoughts?

P.S. .NET 4.0 is set in the MonoDevelop project settings.

Use StartCoroutine(routine: IEnumerator) instead of StartCoroutine(methodName: string, value: object = null).

The co-routine must belong to the class you are starting it from, so in this case you created an empty mono behavior instance, so it has no coMove method.
