c# - unity 通过脚本改变变换对象

问题描述

我有一个脚本，它通过其变换检测对象的距离并将其显示给玩家，我希望目标对象在它被破坏后发生变化，以便目标标记指向不同的对象。到目前为止，这是我的代码

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

public class DistanceToPickup : MonoBehaviour {

    // Reference to checkpoint position
    [SerializeField]
    private Transform checkpoint;

    // Reference to UI text that shows the distance value
    [SerializeField]
    private Text distanceText;
    GameObject exit;
    // Calculated distance value
    private float distance;


    private void Start()
    {
        exit = GameObject.Find("Door_01");

    }


    // Update is called once per frame
    private void Update()
    {

        // Calculate distance value between character and checkpoint
        distance = (checkpoint.transform.position - transform.position).magnitude;

        // Display distance value via UI text
        // distance.ToString("F1") shows value with 1 digit after period
        // so 12.234 will be shown as 12.2 for example
        // distance.ToString("F2") will show 12.23 in this case
        distanceText.text = "Pickup: " + distance.ToString("F1") + " meters";

        if (Pickup.isDestroyed == true)
        {
            //point transform checkpoint to new object
            checkpoint = exit.transform;
            distanceText.text = "Exit: " + distance.ToString("F1") + " meters";
        }
    }

}

我找到了我也想指向标记的游戏对象，并将检查点标记更改为指向出口变换，但它没有改变距离文本，我看不出代码有什么问题。任何帮助都感激不尽

public class Pickup : MonoBehaviour {
    [SerializeField]
    public GameObject m_ExplosionPrefab;
    private ParticleSystem m_ExplosionParticles;
    private int pickupCounter = 0;
    [SerializeField]
    private Text PickupText;
    public static bool isDestroyed;


    private void Update()
    {
        PickupText.text = "Pickups: " + pickupCounter + " /1";
    }
    private void OnEnable()
    {
        // Instantiate the explosion prefab and get a reference to the particle system on it.
        m_ExplosionParticles = Instantiate(m_ExplosionPrefab).GetComponent<ParticleSystem>();

        // Disable the prefab so it can be activated when it's required.
        m_ExplosionParticles.gameObject.SetActive(false);
    }

    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.CompareTag("Player"))
        {
            Destroy(this.gameObject);
            pickupCounter++;
            isDestroyed = true;
            // Move the instantiated explosion prefab to the tank's position and turn it on.
            m_ExplosionParticles.transform.position = transform.position;
            m_ExplosionParticles.gameObject.SetActive(true);

            // Play the particle system of the tank exploding.
            m_ExplosionParticles.Play();

            PickupText.text = "Pickups: " + pickupCounter + " /1";
        }

    }
}

解决方案

尝试改变这个：

    private void Update()
{

    // Calculate distance value between character and checkpoint
    distance = (checkpoint.transform.position - transform.position).magnitude;

    // Display distance value via UI text
    // distance.ToString("F1") shows value with 1 digit after period
    // so 12.234 will be shown as 12.2 for example
    // distance.ToString("F2") will show 12.23 in this case
    distanceText.text = "Pickup: " + distance.ToString("F1") + " meters";

    if (Pickup.isDestroyed == true)
    {
        //point transform checkpoint to new object
        checkpoint = exit.transform;
        distanceText.text = "Exit: " + distance.ToString("F1") + " meters";
    }
}

对此：

    private void Update()
{
    if (Pickup.isDestroyed == true)
    {
        //point transform checkpoint to new object
        checkpoint = exit.transform;
        distanceText.text = "Exit: " + distance.ToString("F1") + " meters";
    }
    else
    {
        // Calculate distance value between character and checkpoint
        distance = (checkpoint.transform.position - transform.position).magnitude;

        // Display distance value via UI text
        // distance.ToString("F1") shows value with 1 digit after period
        // so 12.234 will be shown as 12.2 for example
        // distance.ToString("F2") will show 12.23 in this case
        distanceText.text = "Pickup: " + distance.ToString("F1") + " meters";

   }
}
