UnityTips 之获取 Unity 内置的 图标 Icon

简介： 最近写工具，想用一下 unity 内置的图标，在网上搜到的一段生成代码，修改了一下，做成了 UIElement 显示，记录一下作为备忘
unity版本：20222.3.0fc1

运行效果如下图，点即对应的图标即可复制icon名称到剪切板

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
using UnityEngine.Rendering;
using UnityEngine.UIElements;

public class ShowMeUnityIconsWindow : EditorWindow {
 
[MenuItem(("Window/ShowMeUnityIcons"))]
static void Init(){
    EditorWindow.GetWindow<ShowMeUnityIconsWindow>("UnityTextureWindow");
}
Vector2 m_Scroll;
List<string> m_Icons = null;
void Awake(){
    m_Icons = new List<string>();
    Texture2D[] t = Resources.FindObjectsOfTypeAll<Texture2D>();
    foreach(Texture2D x in t){
        Debug.unityLogger.logEnabled = false;
        GUIContent gc = EditorGUIUtility.IconContent(x.name);
        Debug.unityLogger.logEnabled = true;
        if(gc != null && gc.image != null){
            m_Icons.Add(x.name);
        }
    }
    Debug.Log(m_Icons.Count);
    var scroll = new ScrollView(ScrollViewMode.Vertical);
    rootVisualElement.Add(scroll);
    scroll.StretchToParentSize();
    var container = scroll.Q<VisualElement>("unity-content-container");
    container.style.flexDirection = FlexDirection.Row;
    container.style.flexWrap = Wrap.Wrap;
    foreach (var icon in m_Icons)
    {
        var viewEle = new VisualElement();
        viewEle.style.width = 200;
        viewEle.style.flexDirection = FlexDirection.Row;
        var btn = new Button();
        btn.style.height = 30;
        btn.style.width = 30;
        btn.clicked += () =>
        {
            GUIUtility.systemCopyBuffer =icon;
            ShowNotification(new GUIContent(icon+" copyed to clipboard"),1f);
        };
        var iconObj = EditorGUIUtility.IconContent(icon);
        btn.style.backgroundImage = new StyleBackground(iconObj.image as Texture2D);
        var label = new Label(icon);
        label.style.width = new StyleLength(StyleKeyword.Auto);
        label.style.height = 30;
        viewEle.Add(btn);
        viewEle.Add(label);
        scroll.Add(viewEle);
    }
}
