I’m trying to get an object to spin from 0 to 90 degrees on the Z axis over time, instead of instantly. I’ve tried using Vector3.Lerp, but I’m getting an error saying “The type name ‘Lerp’ does not exist in the type ‘Vector3’”.

```
var finalPos = new Vector3(0, 0, 90);
var desiredPos = new Vector3.Lerp(wheel.rotation, finalPos, Time.deltaTime);
wheel.rotation = Quaternion.Euler(desiredPos);
```

The Lerp function within the Vector3 struct is static. This means you don’t need an instance of a Vector3 to access it and so you don’t need the ‘new’ keyword as that is there for making new objects via their constructors, like you did the line before.

`var desiredPos = Vector3.Lerp(wheel.rotation, finalPos, Time.deltaTime);`

I’ve assumed that this is within a loop or update function, if it’s not then we might need some other changes.

Let me know if it’s not or if you need anything clarified!

@jackmw94 I put that in, but I’m getting an error saying “Argument 1: cannot convert from ‘UnityEngine.Quaternion’ to ‘UnityEngine.Vector3’”. Heres the rest of the code if that helps:

```
using UnityEngine;
public class Flying : MonoBehaviour
{
public float maxHeight;
public float rocketPower;
public Transform[] wheels;
public Rigidbody rb;
void Update()
{
float xPos = transform.position.x;
float yPos = transform.position.y;
if(xPos > -16 && xPos < 30){
foreach(Transform wheel in wheels){
var finalPos = new Vector3(0, 0, 90);
var desiredPos = Vector3.Lerp(wheel.rotation, finalPos, Time.deltaTime);
wheel.rotation = Quaternion.Euler(desiredPos);
}
if(Input.GetKey("space") && yPos < maxHeight){
rb.AddForce(0, rocketPower, 0, ForceMode.Impulse);
}
}
else{
foreach(Transform wheel in wheels){
wheel.rotation = Quaternion.Euler(0, 0, 0);
}
}
}
}
```
