如何使用 Unity 3D 中的 A 和 D 键使播放器 object 旋转？

Question

I need some help as someone brand new to Unity and C# coding. The problem that I am currently facing is that I need my player model to only be able to rotate left and right instead of move on all three axis like many tutorials I have found online. The code I have currently got is:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerRotation : MonoBehaviour
{
    private void Update()
    {
        Rigidbody rb = GetComponent<Rigidbody>();
        if (Input.GetKey(KeyCode.A))
        rb.AddForce(Vector3.left);
        if (Input.GetKey(KeyCode.D))
        rb.AddForce(Vector3.right);
    }

}

But the issue with this is that instead of rotating, the player physically moves left and right. Is anyone able to help with this? (preferably with some code)

Answer 1

Instead of rigidboy, you can directly use the object's transform. So you won't have any problems.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerRotation : MonoBehaviour
{
    public float turnSpeed;
    private void Update()
    {
        if (Input.GetKey(KeyCode.A))
           transform.Rotate(Vector3.left * turnSpeed);
        if (Input.GetKey(KeyCode.D))
           transform.Rotate(Vector3.right * turnSpeed);
    }
}
