Question

我为大型金库门写了一个门剧本。我的问题如下：如果我将脚本分配给多个门在现场，所有门同时打开和关闭其中一个被触动了。

using UnityEngine;
using System.Collections;

public class BigDoorScript : MonoBehaviour
{

    private bool doorOpen = false;
    private Ray ray;
    private RaycastHit hit;
    private float distance = 5.0f;
    public GameObject door;

    private void Update()
    {
        if (Input.GetKeyDown("e"))
        {
            ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            if (Physics.Raycast(ray, out hit, distance))
            {
                if (!doorOpen)
                {
                    door.transform.Translate(new Vector3(0.0f, 0.0f, 4.0f));
                    doorOpen = true;
                }
                else
                {
                    door.transform.Translate(new Vector3(0.0f, 0.0f, -4.0f));
                    doorOpen = false;
                }
            }
        }
    }
}

Answer 1

你根本不必申报门游戏对象。你可以使用hitinfo（＆＃34;点击＆＃34;）。试试这个 -

using UnityEngine;
using System.Collections;

public class BigDoorScript : MonoBehaviour
{

    private bool doorOpen = false;
    private Ray ray;
    private RaycastHit hit;
    private float distance = 5.0f;

    private void Update()
    {
        if (Input.GetKeyDown("e"))
        {
            ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            if (Physics.Raycast(ray, out hit, distance))
            {
                if(hit.collider.gameObject.name == "door"){//Check that your ray is colliding with the door
                    if (!doorOpen)
                    {
                        hit.transform.Translate(new Vector3(0.0f, 0.0f, 4.0f));
                        doorOpen = true;
                    }
                    else
                    {
                        hit.transform.Translate(new Vector3(0.0f, 0.0f, -4.0f));
                        doorOpen = false;
                    }
                }
            }
        }
    }
}

但请确保您的门游戏对象的名称是＆＃34; door＆＃34;没有引号。

Answer 2

您的所有门都打开了，因为您实际上并未检查Raycast中的命中对象是否实际上是您的脚本持有引用的门对象。 Imtiaj简单介绍了这一点，但是游戏对象上的字符串比较是个坏主意，并且不会将自己局限于一个对象，因为许多游戏对象具有相同的名称。

因此，任何碰撞都会打开这个脚本的所有门。

您想要使用

if (hit.collider.gameObject == door)

Answer 3

我认为问题是你的距离值非常大，当你在那个距离的另一扇门上按下该门时也会受到打击。尝试减少该值

Answer 4

我认为你不需要申报门GameObject。只需使用monobehavior上的gameObject属性移动脚本附加到的门：

using UnityEngine;
using System.Collections;

public class BigDoorScript : MonoBehaviour
{
    private bool doorOpen = false;
    private Ray ray;
    private RaycastHit hit;
    private float distance = 5.0f;

    private void Update()
    {
        if (Input.GetKeyDown("e"))
        {
            ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            if (Physics.Raycast(ray, out hit, distance))
            {
                if (!doorOpen)
                {
                    gameObject.transform.Translate(new Vector3(0.0f, 0.0f, 4.0f));
                    doorOpen = true;
                }
                else
                {
                    gameObject.transform.Translate(new Vector3(0.0f, 0.0f, -4.0f));
                    doorOpen = false;
                }
            }
        }
    }
}

Answer 5

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

public class DoorOpen : MonoBehaviour {

    public bool openclosed;
    public float angle;


    public bool InDistance;

    private void Start()
    {

        openclosed = false;
    }

    private void OnTriggerEnter(Collider other)
    {
        InDistance = true;
    }
    private void OnTriggerExit(Collider other)
    {
        InDistance = false;
    }

    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.E) && InDistance == true && openclosed == false)
        {
            openclosed = true;
            transform.Rotate(0, 0, angle);
        }

        else if (Input.GetKeyDown(KeyCode.E) && openclosed == true && InDistance == true)
        {
            openclosed = false;
            transform.Rotate(0, 0, -angle);
        }


    }






}

这是一个简单的开门关闭脚本，没有动画
