Want to rotate cube

I have that code :

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Movement : MonoBehaviour {
6.  
7.     public float speed = 10f;
8.     public float mapWidth = 5f;
9.  
10.     private Rigidbody rb;
11.  
12.     void Start()
13.     {
14.         rb = GetComponent<Rigidbody>();
15.     }
16.  
17.     void FixedUpdate()
18.     {
19.         float x = Input.GetAxis("Horizontal") * Time.deltaTime * speed;
20.  
21.         transform.Rotate(Vector3.up, -Input.GetAxis("Horizontal") * speed * Time.deltaTime);
22.  
23.         Vector3 newPosition = rb.position + Vector3.right * x;
24.  
25.         newPosition.x = Mathf.Clamp(newPosition.x, -mapWidth, mapWidth);
26.  
27.         rb.MovePosition(newPosition);
28.  
29.     }
30. }
31.  

and my cube sliding left and right , but don't rotate in left or right
Can someone help me please?

 

Just delete "speed" from this the line 19. And you can increase speed two times.

Your code must be like:

Code (CSharp):

1.  
2.    void FixedUpdate()
3.     {
4.         float x = Input.GetAxis("Horizontal") * Time.deltaTime;
5.         transform.Rotate(Vector3.up, -Input.GetAxis("Horizontal") * speed);
6.         Vector3 newPosition = rb.position + Vector3.right * x;
7.         newPosition.x = Mathf.Clamp(newPosition.x, -mapWidth, mapWidth);
8.         rb.MovePosition(newPosition);
9.     }
10.  

 

he is not using x in the rotation, on in the position.

Isn't the issue that he is using horizontal to control both position and rotation

 

Yeap, he is not using, but it is Unity Physics. Moving and Rotating both affecting each other (because of Rigidbody). I checked both (his and mine code) on cube object, and saw the effect. So that is why i advised to change
