using UnityEngine;

public class playerlook : MonoBehaviour
{
public transform player;
void Start()
{public float MouseSensitivity = 10;

}
private float x = 0;
private float y = 0;

void Update()
{

}

//input
x += -Iput.GetAxis("Mouse Y") * MouseSensitvity;
y += -Iput.GetAxis("Mouse X") * MouseSensitvity;

//clamping
x = Mathf.Clamp(x, -90, 90),(x, -90, 90);

//rotation
transform.localRotaion = Quaternion.Euler(x, 0, , 0);
playerlook.transform.localRotation = Quaternion.Euler(0, y, 0);

 

1. Check the layout of your code against the examples shown in this link:
Learning C# and coding in Unity for beginners … https://unity3d.com

2. Once you have corrected your layout, check your code for spelling and punctuation mistakes. If you use a code editor such as Visual Studio, any errors in your code will be highlighted as soon as they appear.

3. This particular forum Is for Visual Scripting. Visual scripting, as described in the Unity manual, is a workflow that uses visual, node-based graphs to design behaviours rather than write lines of C# script.

The forum for help with C# scripts is here: Scripting

4. When posting code, please use code tags, as this makes it easier for people to read your code and, thus, increases your chances of getting help:
