如何在untiy 2d中拖动和启动？

Question

我是c#的新手，我一直在尝试获取一些代码来帮助我在与拖拽相反的方向上启动我的角色。喜欢“愤怒的小鸟”，但我不想让角色在我拖拽的时候移动。这是我从视频中复制的脚本，但它不起作用。

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

public class OrbMovement : MonoBehaviour
{
    public float launchSpeed = 100;
    Vector3 _initialPosition;
    Rigidbody2D rb;
    private Vector2 directionToInitialPosition;

    private void Awake()
    {
        _initialPosition = transform.position;
        rb = GetComponent<Rigidbody2D>();
        directionToInitialPosition = _initialPosition - transform.position;
    }

    private void OnMouseUp()
    {
        rb.AddForce(directionToInitialPosition *launchSpeed);
    }

    private void OnMouseDrag()
    {
        Vector3 newPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        transform.position = new Vector3(newPosition.x, newPosition.y);
    }

}
`

帮我写一个脚本，让我的角色与拖拽相反。提前感谢:)

你为什么不干脆把

    private void OnMouseDrag()
    {
        Vector3 newPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        transform.position = new Vector3(newPosition.x, newPosition.y);
    }

脚本的这一部分意味着每次玩家拖动鼠标/触摸时，游戏对象都会跟随鼠标。因为你不想要它，所以你可以把它移到

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

public class OrbMovement : MonoBehaviour
{
    public float launchSpeed = 100;
    Vector3 _initialPosition;
    Rigidbody2D rb;
    private Vector2 directionToInitialPosition;

    private void Awake()
    {
        _initialPosition = transform.position;
        rb = GetComponent<Rigidbody2D>();
        directionToInitialPosition = _initialPosition - transform.position;
    }

    private void OnMouseUp()
    {
        rb.AddForce(directionToInitialPosition *launchSpeed);
    }
}
