c# - 怎么做rb.AddForce而不是2D？ Unity C#

Question

我正在制作一个2D游戏，您需要控制盾牌，并且必须阻止掉落的障碍物到达基地。我知道要移动某些内容，您可以使用rb.addforce。但是，当我对2D执行相同操作时，它将无法正常工作。我想象不是使用Vector3，而是使用Vector2，但是每次我编写该行时，它都会给我带来两个错误:Assets\Movement.cs(16,25): error CS1503: Argument 1: cannot convert from 'float' to 'UnityEngine.Vector2'和这个错误:Assets\Movement.cs(16,25): error CS1503: Argument 1: cannot convert from 'float' to 'UnityEngine.Vector2'。这是我的完整代码:

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

public class Movement : MonoBehaviour
{
    public Rigidbody2D rb;
    public Collider2D collider;

    public float moveSpeed = 0.1f;

    private void Update() 
    {
        if (Input.GetKey("w"))
        {
            rb.AddForce(0f, moveSpeed);
            Debug.Log("w");
        }

        if (Input.GetKey("s"))
        {
            rb.AddForce(0f, moveSpeed);
            Debug.Log("s");
        }
    }
}

您可以在Vector2中添加新的rb.AddForce (new Vector2(0,moveSpeed));这是更新的代码:

 public class Movement : MonoBehaviour
    {
        public Rigidbody2D rb;
        public Collider2D collider;

        public float moveSpeed = 0.1f;

        private void Update()
        {
            if (Input.GetKey("w"))
            {
                rb.AddForce(new Vector2(0f, moveSpeed));
                Debug.Log("w");
            }

            if (Input.GetKey("s"))
            {
                rb.AddForce(new Vector2 (0f, moveSpeed));
                Debug.Log("s");
            }
        }
    }
