Javascript 拾取和移动周围的对象

我试着在c#中找到一个例子，把一个物体放到玩家的手的位置，然后四处移动。我在unity论坛上找到了一个例子，但是它在C#中如何实现呢

这是我找到的代码，但我需要在单击按钮时抓取它，播放器需要在对象前面

#pragma strict

var TheSystem : Transform;
var Distance : float;
var MaxDistance : float = 10;  

function Update() {



       var hit : RaycastHit;
     if (Physics.Raycast (TheSystem.transform.position, TheSystem.transform.TransformDirection(Vector3.forward), hit))
     {    
        if(hit.transform.gameObject.tag == "sword2"){


         Distance = hit.distance;
         if (Distance < MaxDistance){


             if (Input.GetKeyDown(KeyCode.E)) {
                // show
             renderer.enabled = true;
             Destroy (GameObject.FindWithTag("sword2"));
                  } 

            if (Input.GetKeyDown(KeyCode.Backspace)) {
            // hide
            renderer.enabled = false;
                 }

          }
      }
  }
  }

为了实现你心中的目标，有必要将许多事情结合起来

用于检测玩家何时靠近对象的触发器

读取播放机的输入，检查播放机是否已按下或松开 抓取对象的按钮

更改游戏对象在玩家手中的位置 性格

使抓取的游戏对象成为手的子对象。所以两个人一起行动

此脚本解决了上述所有步骤。您需要注意添加刚体和碰撞器。此外，您还需要将要收集的对象标记为“项”

额外注意：如果您将收集的物品设置为另一个带有网格的游戏对象的子对象，例如手，子对象将更改其形状。因此，请使用放置在手部位置的空游戏对象。并将该空游戏对象作为此脚本的参数传递给检查器

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

public class moveObject : MonoBehaviour {

    public GameObject handEmptyGameObject;
    GameObject item = null;

    bool objectOnRange = false;

    // Use this for initialization
    void Start () {
        //This is useful if you have just one item to collect in your scene
        //if you have more than one, better remove it
        item = GameObject.FindGameObjectsWithTag("item");
    }

    // Update is called once per frame
    void Update () {
        if(Input.GetKeyDown(KeyCode.G) && objectOnRange)
        {
            print("Grabbing an object");
            item.transform.position = hand.transform.position;

            item.transform.SetParent(hand.transform,true);
        }
    }

    //You need to tag the GameObjec tto grab as "item" and set a 
    //collider and rigid bodies in the GameObjects
    //This is to estimate if the player is close enough to the Object

    void OnTriggerEnter(Collider other)
    {
        if(other.tag == "item")
        {
            objectOnRange = true;
            item = other.gameObject;
        }
    }

    void OnTriggerExit(Collider other)
    {
        if(other.tag == "item")
        {
            objectOnRange = false;
            item = other.gameObject;
        }
    }

}

你在哪里尝试“翻译”这个？你遇到了什么问题？

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

public class moveObject : MonoBehaviour {

    public GameObject handEmptyGameObject;
    GameObject item = null;

    bool objectOnRange = false;

    // Use this for initialization
    void Start () {
        //This is useful if you have just one item to collect in your scene
        //if you have more than one, better remove it
        item = GameObject.FindGameObjectsWithTag("item");
    }

    // Update is called once per frame
    void Update () {
        if(Input.GetKeyDown(KeyCode.G) && objectOnRange)
        {
            print("Grabbing an object");
            item.transform.position = hand.transform.position;

            item.transform.SetParent(hand.transform,true);
        }
    }

    //You need to tag the GameObjec tto grab as "item" and set a 
    //collider and rigid bodies in the GameObjects
    //This is to estimate if the player is close enough to the Object

    void OnTriggerEnter(Collider other)
    {
        if(other.tag == "item")
        {
            objectOnRange = true;
            item = other.gameObject;
        }
    }

    void OnTriggerExit(Collider other)
    {

        {
