触发触发器后如何更改整个对象的颜色？

Question

我正在制作化学分子游戏。到目前为止，我有一个在受体位点上带有触发器的分子，当我将正确的原子拖到靠近该位点时，原子会改变颜色并附着。一旦连接了这个原子，我如何改变整个分子（不仅仅是 trigger/receptor 位点）的颜色？

我游戏这部分使用的代码来自：https://gamedev.stackexchange.com/questions/123929/snap-an-object-to-another-object

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

public class Snap : MonoBehaviour
{

    public string partnerTag;
    public float closeVPDist = 0.05f;
    public float farVPDist = 1;
    public float moveSpeed = 40.0f;
    public float rotateSpeed = 90.0f;

    private Vector3 screenPoint;
    private Vector3 offset;
    private bool isSnaped;
    Color color = new Color(2, 1, 3);

    float dist = Mathf.Infinity;
    Color normalColor;
    GameObject partnerGO;
    // Use this for initialization
    void Start()
    {
        normalColor = GetComponent<Renderer>().material.color;
        partnerGO = GameObject.FindGameObjectWithTag(partnerTag);
    }
    void OnMouseDown()
    {
        screenPoint = Camera.main.WorldToScreenPoint(transform.position);
        offset = transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z));
        Cursor.visible = false;
    }
    void OnMouseDrag()
    {
        //transform.SetParent(null);
        Vector3 curScreenPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
        Vector3 curPosition = Camera.main.ScreenToWorldPoint(curScreenPoint) + offset;
        transform.position = curPosition;
        Vector3 partnerPos = Camera.main.WorldToViewportPoint(partnerGO.transform.position);
        Vector3 myPos = Camera.main.WorldToViewportPoint(transform.position);
        dist = Vector2.Distance(partnerPos, myPos);
        GetComponent<Renderer>().material.color = (dist < closeVPDist) ? color : normalColor;
    }
    void OnMouseUp()
    {
        Cursor.visible = true;
        if (dist < closeVPDist)
        {
            transform.SetParent(partnerGO.transform);
            StartCoroutine(InstallPart());
            isSnaped = true;
        }
        if (dist > farVPDist)
        {
            //  transform.SetParent(null);
        }
    }
    IEnumerator InstallPart()
    {
        while (transform.localPosition != Vector3.right || transform.localRotation != Quaternion.identity)
        {
            transform.localPosition = Vector3.MoveTowards(transform.localPosition, Vector3.right, Time.deltaTime * moveSpeed);
            transform.localRotation = Quaternion.RotateTowards(transform.localRotation, Quaternion.identity, Time.deltaTime * rotateSpeed);
            yield return new WaitForEndOfFrame();
        }
    }
}

在 OnMouseUp 中，添加一行以更改分子的 material/colour。代码：

public Color newColor;
public GameObject objectToChangeColour;    
void OnMouseUp()
{
    Cursor.visible = true;
    if (dist < closeVPDist)
    {
        transform.SetParent(partnerGO.transform);
        StartCoroutine(InstallPart());
        isSnaped = true;
        objectToChangeColour.GetComponent<Renderer>().material.color = newColour; // Change the color of object to the newColour
    }
    if (dist > farVPDist)
    {
        //  transform.SetParent(null);
    }
}

然后简单地将 objectToChangeColour 更改为您想要更改其颜色的对象 (parentGO/molecule/etc)，然后将 newColour 更改为新颜色。

How do I change the colour of the whole object once its trigger has been hit?
