Hi! My question would be this: How can I limit the rotation of an object, because it seems like the Mathf.Clamp doesn't work have I wanted it. I want it on the x and on the z axis (Im new to Unity))

Question

using System.Collections; using System.Collections.Generic; using System.Collections.Specialized; using System.Runtime; using UnityEngine;

public class swordrotation : MonoBehaviour {

 public float mouseSensitivity = 100f;

 public Transform SwordRotation;

 float xRotation = 0f;
 float zRotation = 0f;
 // Start is called before the first frame update
 void Start()
 {
     Cursor.lockState = CursorLockMode.Locked;
 }

 // Update is called once per frame
 void Update()
 {
     
     if (Input.GetMouseButton(0))
     {
         float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
         float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;

         xRotation = Mathf.Clamp(xRotation, -40, 60);
         zRotation = Mathf.Clamp(zRotation, -90, 90);

         SwordRotation.Rotate(new Vector3(10f, 0f, 0f) * mouseY);
         SwordRotation.Rotate(new Vector3(0f, 0f, 10f) * mouseX);
     }
 }

}

To clamp the rotation of an object you should keep track of your rotation angles and set the rotation every frame, something like this -

 public float xMin = -40f;
 public float xMax = 60f;
 public float zMin = -90f;
 public float zMax = 90f;
 
 private Vector3 rotation;
 
 void Update(){
     mouseY = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
     mouseX = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;
 
     float xRotation = Mathf.Clamp(rotation.x + mouseX, xMin, xMax);
     float yRotation = Mathf.Clamp(rotation.y + mouseY, yMin, yMax);
     rotation = new Vector3(xRotation, yRotation, 0);
     
     SwordRotation.rotation = rotation;
 }

Where you can clamp your overall rotation values, then apply those clamped values every frame
