Having trouble with a 'lerp' script?

Hi
I have a script that should toggle my camera from point A to point B when the input 'SwitchShoulders' is pressed.

Here's the script:

Code (CSharp):

1. public class TogglePosition : MonoBehaviour
2. {
3.     public Vector3 leftPosition = new Vector3(-4177.642f, -3220.743f, 6346.121f);
4.     public Vector3 rightPosition = new Vector3(5159.432f, -3220.743f, 5764.928f);
5.     public float speed = 1000f;
6.    
7.     void Update()
8.     {
9.         if (Input.anyKeyDown)
10.             movingToRightPosition = !movingToRightPosition; // Go towards other position.
11.         Vector3 targetPosition = movingToRightPosition ? rightPosition : leftPosition;
12.         transform.position = Vector3.MoveTowards(transform.position, targetPosition, speed * Time.deltaTime);
13.     }
14.    
15.     bool movingToRightPosition;
16. }

But I keep getting the error:
"Assets/SwitchShoulders.cs(1,31): error CS0246: The type or namespace name `MonoBehaviour' could not be found. Are you missing a using directive or an assembly reference?"

How do I fix this?

 

You're missing the UnityEngine namespace. Add the following line to the top of your code:

Code (csharp):

1.  
2. using UnityEngine;
3.  
4. // declare your class here
5.  

Also, the bool movingToRightPosition should be declared before Update.
