Unity实现通用的物体高亮闪烁的方法（轮廓或整体高亮闪烁）
一、导入DoTween或DoTweenPro插件到项目中
二、编写一个控制物体轮廓高亮闪烁的脚本，如下图所示：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
namespace Global
{
public class Global_CtrlHightLighting : MonoBehaviour
{
public HighlightableObject m_ho; //持有当前外发光需要的组件
private float shineTime = 1F; //持续发光时间
/// <summary>
/// 高亮闪烁设置
/// </summary>
public void HighLightSettings()
{
//循环往复外发光开启（参数为：颜色1，颜色2，切换时间）
m_ho.FlashingOn(Color.cyan, Color.grey, shineTime);
//关闭循环往复外发光
m_ho.FlashingOff();
//持续外发光开启（参数：颜色）
m_ho.ConstantOn(Color.blue);
//关闭持续外发光
m_ho.ConstantOff();
}
/// <summary>
/// 启用高亮
/// </summary>
public void EnableHighLight()
{
//开启外发光
m_ho.FlashingOn(Color.cyan, Color.grey, shineTime);
}
/// <summary>
/// 禁用高亮
/// </summary>
public void DisableHighLight()
{
//关闭外发光
m_ho.FlashingOff();
}
}//class_end
}
三、编写通用的实现物体轮廓或者整体高亮闪烁的脚本，如下所示：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using Global;
using kernal;
using Control;
namespace View
{
public class View_SingleEquipmentPartControl : MonoBehaviour
{
#region 添加的控制组件
private HighlightableObject _HighlightableObject; //物体发光必要组件
private Global_CtrlHightLighting _CtrlHightLighting; //物体发光控制组件
private GameObjectDisplayUI _GameObjectDisplayUI; //面板显示在部件对应位置的控制组件
#endregion
#region 鼠标移入移出参数
public bool isMouseEnter = false; //鼠标是否进入
public bool isMouseArea = false; //鼠标是否在区域内
private string _MouseEnterEquipmentPartName; //鼠标移入的设备部件名称
#endregion
#region 使用Shader实现高亮效果参数
public GameObject[] equipmentParts = new GameObject[10]; //需要改变颜色的设备部件
private Dictionary<string, Material> _EquipmentPartsOriginalMatDic; //设备拆分部件原本材质球字典
private Material _HighlightMat; //高亮效果材质球
private Material[] _HighlightMats; //高亮效果材质球集合
#endregion
#region 设备部件详细信息参数
public Transform equipmentPartControl;
private View_EquipmentPartInfo _EquipmentPartInfo;
#endregion
void Start()
{
//给该部件添加必要的控制组件
AddControlComponet();
//实例化
_EquipmentPartsOriginalMatDic = new Dictionary<string, Material>();
}
#region 鼠标事件方法
/// <summary>
/// 鼠标进入设备部件高亮
/// </summary>
private void OnMouseEnter()
{
isMouseEnter = true;
if (_HighlightableObject != null && _CtrlHightLighting != null)
{
//开启高亮
IsEquipmentPartHighlight(0, true);
_MouseEnterEquipmentPartName = this.gameObject.name;
//print("_MouseEnterEquipmentPartName=" + _MouseEnterEquipmentPartName);
}
}
//鼠标在设备部件区域内
private void OnMouseOver()
{
print("鼠标在区域内");
isMouseArea = true;
}
/// <summary>
/// 鼠标退出设备部件
/// </summary>
private void OnMouseExit()
{
isMouseEnter = false;
isMouseArea = false;
if (_HighlightableObject != null && _CtrlHightLighting != null)
{
//不开启高亮
IsEquipmentPartHighlight(0);
//清空鼠标移入的部件名称
_MouseEnterEquipmentPartName = "";
}
}
#endregion
#region 私有方法

private void AddControlComponet()
{
_HighlightableObject = new HighlightableObject();

{
_CtrlHightLighting = this.gameObject.AddComponent<Global_CtrlHightLighting>();
_CtrlHightLighting.m_ho = _HighlightableObject;
}
else
{
_CtrlHightLighting = this.gameObject.GetComponent<Global_CtrlHightLighting>();
_CtrlHightLighting.m_ho = _HighlightableObject;
}
}
/// <summary>

break;
default:
break;

if (go[i].GetComponent<MeshRenderer>() != null)
{
if (!_EquipmentPartsOriginalMatDic.ContainsKey(go[i].name))
{
Material mat = go[i].GetComponent<Renderer>().material;
//print("材质球=" + mat);
_EquipmentPartsOriginalMatDic.Add(go[i].name, mat);

四、将 View_SingleEquipmentPartControl脚本添加给需要实现轮廓或者整体高亮闪烁的物体（这里默认使用整体高亮闪烁），给该物体添加碰撞体、指定对应的需要实现整体高亮闪烁的物体，如下图所示：
五、运行测试、鼠标移入到该物体，该物体高亮、鼠标移出该物体则该物体恢复为正常，如下图所示：
六、实现物体整体高亮的Shader链接如下：

注意： private Material _HighlightMat; //高亮效果材质球 的加载路径根据自身的项目（实现物体整体高亮的Shader放置的位置）改变。
