For this, you need to follow the advice in the error message : **Consider storing the value in a temporary variable**

Let’s look at that.

```
if (transform.position.y < -20)
{
    // build a temporary Vector3
    Vector3 tempPosition = new Vector3( 3.5f, 0.2f, -0.1f);

    // assign the Vector3 to the transform.position
    transform.position = tempPosition;
}     

```

This is untested and C# is not my native language =]
