Question

我是Unity的新手，并且一直在关注如何制作Captain Blaster 2D游戏的教程，但我想将其转换为Android，我想通过用一根手指将他拖过屏幕让玩家可以控制并且不明白我的代码有什么问题，有什么帮助，谢谢

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

public class ShipControl : MonoBehaviour {

    public float playerSpeed = 10f;
    public GameControl gameController;
    public GameObject bulletPrefab;
    public float reloadTime = 1f;

    private float elapsedTime = 0;


    void Update()
    {

        elapsedTime += Time.deltaTime;
        if (Input.touchCount >= 1)
        {
            foreach (Touch touch in Input.touches) 
            {
                Ray ray = Camera.main.ScreenPointToRay (touch.position);
                RaycastHit hit;
                if (Physics.Raycast (ray, out hit, 100)) {

                }
            }

        if (elapsedTime > reloadTime)
        {
            Vector3 spawnPos = transform.position;
            spawnPos += new Vector3 (0, 1.2f, 0);
            Instantiate (bulletPrefab, spawnPos, Quaternion.identity);

                elapsedTime = 0f;
        }
        }
    }
    void OnTriggerEnter2D(Collider2D other)
    {
        gameController.PlayerDied ();
    }

}

我要做的是添加一个名为＆＃34;拖动＆＃34;在你检查Raycast是否击中任何东西后，你还要检查命中对象是否是玩家GameObject。如果是，只要用户没有释放触摸 - 让玩家的刚体移动到触摸位置（所以如果有任何障碍物，它就不会直接穿过它们）。

代码可能看起来像这样（你还应该添加一些计时器来检查玩家是否释放了触摸并将拖动bool设置为false）：

public float playerSpeed = 10f;
public GameControl gameController;
public GameObject bulletPrefab;
public float reloadTime = 1f;

private float elapsedTime = 0;

private bool dragging = false;


void Update()
{

    if (Input.touchCount >= 1)
    {
        foreach (Touch touch in Input.touches) 
        {
            Ray ray = Camera.main.ScreenPointToRay (touch.position);
            RaycastHit hit;

            if (Physics.Raycast (ray, out hit, 100)) 
            {
                if(hit.collider.tag == "Player") // check if hit collider has Player tag
                {
                    dragging = true;
                }
            }

            if(dragging)
            {
                //First rotate the player towards the touch (should do some checks if it's not too close so it doesn't glitch out)
                Vector3 _dir = Camera.main.ScreenToWorldPoint(touch.position) - transform.position;
                _dir.Normalize();

                float _rotZ = Mathf.Atan2(_dir.y, _dir.x) * Mathf.Rad2Deg;
                transform.rotation = Quaternion.Euler(0f, 0f, _rotZ - 90);

                //Move towards the touch
                transform.GetComponent<Rigidbody>().AddRelativeForce(direction.normalized * playerSpeed, ForceMode.Force);
            }
        }
    }
}
