统一代码不允许角色（2D，刚体）在空中转向。我怎样才能用这个脚本获得更多的空气控制？

Question

在 Unity 中为我的游戏编写 2D 运动代码时，我遇到了问题。以前我决定让角色不能在空中移动，但是我想改变它。我该怎么做？我希望角色能够在空中转向，但速度不同于“moveSpeed”。这是我第一次访问这个网站，所以如果我泄露了太多细节，我深表歉意。以下是移动和跳跃脚本：

步行脚本

      public bool canMove = true;

        [SerializeField] public Vector2 newVelocity;
        [SerializeField] public Rigidbody2D rb;
        [SerializeField] public float moveSpeed = 10f;
        [SerializeField] public Vector2 direction;
        [SerializeField] public float wallSlideSpeed;
        public float movementForceAir;
        public float airDragMultiplier;
        FlipChar flipc;
        GroundCheck gc;
        SlopeWalk sw;
        PlayerJump pj;
        WallChecker wc;
        DashAfterimage da;

        void Awake()
        {
            gc = GetComponent<GroundCheck>();
            sw = GetComponent<SlopeWalk>();
            rb = GetComponent<Rigidbody2D>();
            pj = GetComponent<PlayerJump>();
            wc = GetComponent<WallChecker>();
            da = GetComponent<DashAfterimage>();
        }

        void Start()
        {
            flipc = GetComponent<FlipChar>();

        }

        void Update()
        {


        }

        void FixedUpdate()
        {
            if (gc.onGround && canMove && !da.dashing)
            {
                rb.velocity = new Vector2(Input.GetAxis("Horizontal") * moveSpeed, rb.velocity.y);
            }
            else if (!gc.onGround && !wc.isWallSliding && Input.GetAxis("Horizontal") != 0)
            {

                Vector2 forceToAdd = new Vector2(movementForceAir * Input.GetAxis("Horizontal"), 0);
                rb.AddForce(forceToAdd);

                if (Mathf.Abs(rb.velocity.x) > moveSpeed)
                {
                    rb.velocity = new Vector2(moveSpeed * Input.GetAxis("Horizontal"), rb.velocity.y);


                    //          }else if(!gc.onGround && !wc.isWallSliding && Input.GetAxis("Horizontal") == 0){
                    //           rb.velocity = new Vector2(rb.velocity.x , rb.velocity.y);
                }
            }


            if (wc.isWallSliding)
            {
                if (rb.velocity.y < wallSlideSpeed)
                {
                    rb.velocity = new Vector2(rb.velocity.x, -wallSlideSpeed);
                }
            }

        }


    }
}

我会使用 2d 碰撞器来检查您是否接触到地面物体。然后在你的移动方法上我会检查你是否在触摸它。如果不是，请更改移动速度。
