C#我如何从我在另一个类中使用方法的类中获取数据，而不使用参数

Question

Player.Jump(GetComponent<Rigidbody2D>);

Player.Jump();

    /// <summary>
    /// Makes the given Rigidbody2D jump.
    /// </summary>
    public static void Jump(Rigidbody2D rb)
    {
        rb.velocity = new Vector2(rb.velocity.x, 0);
        rb.AddForce(new Vector2(0, JumpHeight));
    }

if (Player.CanMove)
    {
        Player.Move(rb);

        if (Input.GetKeyDown(KeyCode.Space) && canJump)
        {
            if (tempMaxJumps > 0)
            {
                Player.Jump(rb);
                tempMaxJumps--;
            }
            else
            {
                canJump = false;
            }
        }
    }

如果您真的需要player类保持静态类，我建议简单地添加一个

公共静态刚体2D刚体；

您可以在调用jump的类的start中为其分配一次
