Child object spinning when parent object stopped?

Questions & Answers

I’m currently just practising making basic scripts. I made two separate scripts for the camera and a player to make them look on separate axis. The camera looks on the Y axis whilst the player looks on the X axis. This is to stop the player object from lying on a 90 degree angle. I also set the camera to be a child object of the player so that it’ll look on the X axis with the player. The problem is that when I move my mouse to rotate the player it stops when the mouse stops but the camera continues spinning until I move the mouse in the opposite direction to cancel the rotation.
Here’s the code for the player object:
using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour {
	public int speed;
	public float turnSpeed;

	private Vector3 movement;
	private Quaternion turn;

	Rigidbody playerRB;

	// Use this for initialization
	void Start () {
		playerRB = GetComponent<Rigidbody> ();
		playerRB.freezeRotation = true;
	}
	
	// Update is called once per frame
	void Update () {
		movement = new Vector3 (Input.GetAxis ("Horizontal"), 0.0f, Input.GetAxis ("Vertical"));
		transform.Translate (movement * Time.deltaTime * speed);
		turn.eulerAngles = new Vector3 (0.0f, Input.GetAxis ("Mouse X"), 0.0f);
		Quaternion current = transform.localRotation;
		transform.localRotation = Quaternion.Slerp (current, current * turn, Time.deltaTime * turnSpeed);
	}
}

And this is the cameras:

using UnityEngine;
using System.Collections;

public class CameraController : MonoBehaviour {
	private Quaternion turn;
	private GameObject player;
	private float turnSpeed;

	// Use this for initialization
	void Start () {
		turnSpeed = GameObject.Find ("Jeff").GetComponent<PlayerController> ().turnSpeed;
	}
	
	// Update is called once per frame
	void Update () {
		turn.eulerAngles = new Vector3 (Input.GetAxis ("Mouse Y"), 0.0f, 0.0f);
		transform.localRotation = Quaternion.Slerp (transform.localRotation, transform.rotation * turn, Time.deltaTime * turnSpeed);
		transform.localRotation.x = transform.localRotation.x;
	}
}

Anyone know how to fix it?

Try to replace transform.rotation with transform.localRotation in the Slerp method (second paramter).
That may help even though I’m afraid that Slerp is used a bit incorrectly.

Also, the last assignment in the Update function should throw an error. You may need to save the rotation in a temporary variable first, change it there, and re-assign it.
