public class MouseLock : MonoBehaviour
{
 
    public float mouseSensitivity = 100f;

    public Transform playerBody; 
 
    float xRotation = 0f;

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        float mouseX = Input.GetAxis("MouseX") = mouseSensitivity = Time.deltaTime;
        float mouseY = Input.GetAxis("MouseY") = mouseSensitivity = Time.deltaTime;

        xRotation -= mouseY;

        transform localRotation = Quaternion.Euler(xRotation, 0f, 0f);
        playerBody.Rotate(Vector3.up = mouseX);
    }
}

Sorry we cannot guess which line of code causes the problem. In the meantime take a look at Compiler Error CS0246 | Microsoft Docs[^], which explains what the error is. You should then be able to correct the mis-spelling or add the correct type or namespace to your project, as appropriate.

If you get an error you don't understand, google it: CS0246 error - Google Search[^]
The top hit explains the what error means: Compiler Error CS0246 | Microsoft Docs[^]

Now look at the line that the error message refers to and think about the types and classes that it is trying to use. Where are they? What references has your project gotr, and does it include the one they are included in?

We can't do that for you: we don't even know which line the problem is being found on, much less examine your project to list the references!

You should expect to get syntax errors every day, probably many times a day while you are coding - we all do regardless of how much experience we have! Sometimes, we misspell a variable, or a keyword; sometimes we forget to close a string or a code block. Sometimes the cat walks over your keyboard and types something really weird. Sometimes we just forget how many parameters a method call needs.

We all make mistakes.

And because we all do it, we all have to fix syntax errors - and it's a lot quicker to learn how and fix them yourself than to wait for someone else to fix them for you! So invest a little time in learning how to read error messages, and how to interpret your code as written in the light of what the compiler is telling you is wrong - it really is trying to be helpful!

So read this: How to Write Code to Solve a Problem, A Beginner's Guide Part 2: Syntax Errors[^] - it should help you next time you get a compilation error!
