Cannot implicitly convert type `UnityEngine.Vector2' to `float'

Hello there, I am currently following the Unity Space Shooter video guide, and I am on Part 09. I am pretty much following the tutorial straight, except for the fact that I am doing it in 2D instead of 3D.

The error I am getting: “Assets/Scripts/RandomRotator.cs(9,29): error CS0029: Cannot implicitly convert type UnityEngine.Vector2' to float’”

My problem is, that I am trying to create an asteroid, with a random rotation, by using rigidbody2D.angularVelocity = Random.insideUnitCircle * tumble; Which is giving me an error, here is my entire script:

using UnityEngine;
using System.Collections;

public class RandomRotator : MonoBehaviour {

	public float tumble;

	void Start(){
		rigidbody2D.angularVelocity = Random.insideUnitCircle * tumble;
	}
}

Rigidbody2D.angularVelocity is a float since in 2D you only have one axis of rotation. So you can do something like:

   rigidbody2D.angularVelocity = Random.vaule * tumble;

Also keep in mind that Rigidbody.angularVelocity is in Radians, and Rigidbody2D.angularVeclocity is in degrees, so you will need to adjust ‘tumble’ as appropriate.
