拓展控件

需求

比如我想在添加Text时，自动添加一个脚本，用于处理多语言。在添加图片时，自动去掉raycast的勾选以节约性能损耗

解决方案

方案

ObjectFactory.componentWasAdded 用于监听组件的添加事件

using TMPro;
using UnityEngine;
using UnityEditor;
using UnityEngine.UI;
using UnityEngine.EventSystems;
/// <summary>
/// Inspector面板添加组件回调
/// </summary>
[InitializeOnLoad]
public class InspectorAddComponent
{static InspectorAddComponent(){//监听组件添加事件ObjectFactory.componentWasAdded += ComponentWasAdded;}private static void ComponentWasAdded(Component com){switch (com.GetType().ToString()){case "UnityEngine.UI.Image":ComponentOptimizing.OptimizingImage(com as Image);break;case "UnityEngine.UI.Text":ComponentOptimizing.OptimizingText(com as Text);break;case "UnityEngine.UI.Button":ComponentOptimizing.OptimizingButton(com as Button);break;case "UnityEngine.UI.Mask":ComponentOptimizing.OptimizingMask(com as Mask);break;case "TMPro.TextMeshProUGUI":ComponentOptimizing.OptimizingTmp(com as TextMeshProUGUI);break;}}
}

using TMPro;
using Unity.VisualScripting;
using UnityEditor;
using UnityEditor.Events;
using UnityEngine;
using UnityEngine.Events;
using UnityEngine.EventSystems;
using UnityEngine.UI;/// <summary>
/// 组件优化设置
/// </summary>
public class ComponentOptimizing
