'StartCoroutine' does not exist in the current context

Questions & Answers

Hello, I'm converting my project from JS to C# and I believe this is the very last of the hundreds of errors I had to resolve in the process. I'm receiving the error "StartCoroutine' does not exist in the current context " on line 312.

In method:

public void OnControllerColliderHit(ControllerColliderHit hit)
{
    [...]

    component = gameObj.GetComponent("MovementReverse");
    if(component != null)
    {
        MovementReverse handler;
        handler = component as MovementReverse;

        StartCoroutine(MovementReverse(handler)); // line 312 with the trouble
    }

    [...]
}

This is within my BlobController class:

[RequireComponent(typeof (CharacterController))]
public class BlobController : Component

And my file has the standard usings:

using UnityEngine;
using System.Collections;

Oddly, StartCoroutine appears in the intellisense in MonoDevelop as a method, however when typing the parenthesis '(' it doesn't display the typical box to let you know what arguments are required, which seems to imply that some library isn't properly referenced or something, however even the reference in the Unity manual doesn't have any additional using statements.

In addition, I've tried all of these lines, none work:

StartCoroutine(MovementReverse(handler));
yield return StartCoroutine(MovementReverse(handler)); // changed method return type to IEnumerator
StartCoroutine(new MovementReverse(handler));
yield return StartCoroutine(new MovementReverse(handler));

Am I doing it wrong? I'm stumped.

Edit 1: Here's the coroutine I'm calling:

    public IEnumerator MovementReverse(MovementReverse handler)
    {
        // stop blob from moving
        StopMoving();

        // wait, will resume this public void at this spot after 1 second
        yield return new WaitForSeconds(handler.delayBeforeReversing);

        [...]
    }

According to the reference and some blog posts, this appears to be correct, what is going wrong?

BlobController should be MonoBehaviour not Component

Your class is:

public class BlobController : Component

The function you're trying to call is:

MonoBehaviour.StartCoroutine

Check this blog post:

And the previous blog post refers to this guys use of coroutines in Java, so may help you figure out what's going on. My guess would be you need the

IEnumerator MyCoroutine()

part

StartCoroutine is a member of MonoBehaviour class (a none static one) so your class must derrive from MonoBehaviour to be able to call/use it.
