我的 c# 代码在 Unity 中收到很少的错误消息

Question

so I'm creating a simple 2D game in unity and at some point, I'm getting a few errors I think it's because I'm using an old way of writing so if someone can give me a modern way of writing the C# code it will help me very much

Here is the code:

    using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    public float moveSpeed;

    public Rigidbody2D rb;
    private Vector3 velocity = Vector3.zero;

    void FixedUpdate()
    {
        float horizontalMovement = Input.GetAxis("Horizontal") * moveSpeed * Time.deltaTime;

        MovePlayer(horizontalMovement);
    }

    void MovePlayer(float _horizontalMovement)
    {
        Vector3 targetVelocity = new Vector2(_horizontalMovement, rb.velocity.y);
        rb.velocity = Vector3.SmoothDamp(rb.velocity, targetVelocity, ref velocity, .05f);
    }
}

And here are the errors:

Yeah I know it's a lot sorry about that I'm still a beginner

Answer 1

Try going to Edit>Preferences>External Tools> Set your External Script editor to the correct version of vs, and then click "Regenerate project Files" button.

I see errors like this in my projects from time to time, and this almost always seems to fix it.
