准备工作,首先需要安装TexturePacker-5.1.0-x64.msi,我使用的版本,因为软件付费,不需要担心水印问题.
其次,在unity中安装插件TexturePackerImporter.
需求方案是针对美术某目录下面所有子文件夹,对每一个文件夹里面所有素材做一个图集,生成spritesheet的metaData,方便程序用代码去控制调用,习惯NGUI的程序可以理解为atlas.
如果不想使用付费软件可以看下面这个网址:

用这个办法也可以实现下面的需求

自动成生atlas文件类
using UnityEngine;
using System.Collections;
using UnityEditor;
using System.IO;
public class UIAtalsEditor : Editor
{
[MenuItem("Tools/CMD/自动创建Plot图集的Atlas")]
public static void AutoCreateAtlasPrefab()
{
string inputPath = PathManager.FileBasePath() + "/_Project/Modules/_Common/GUI/_OutTexture/Plot/";
string[] files = Directory.GetFiles(inputPath, "*.png", SearchOption.TopDirectoryOnly);
for (int i = 0; i < files.Length; i++)
{
//Debug.Log(files[i]);
string assetPath = "Assets" + files[i].Substring(Application.dataPath.Length);
//Debug.Log(assetPath);
Object assetObj = AssetDatabase.LoadAssetAtPath<Object>(assetPath);
//Debug.Log(assetObj);
Selection.activeObject = assetObj;
CreateAtlasPrefab();
}
EditorUtility.DisplayDialog("", "全部生成图片的Atlas结束", "确定");
}
[MenuItem("Tools/UGUI/创建当前选中图集的Atlas")]
public static void CreateAtlasPrefab()
{
if (Selection.activeObject != null)
{
string path = AssetDatabase.GetAssetPath(Selection.activeObject);
TextureImporter importer = AssetImporter.GetAtPath(path) as TextureImporter;
if (importer != null && importer.textureType == TextureImporterType.Sprite && importer.spriteImportMode == SpriteImportMode.Multiple)
{
UIAtals atlas = CreateInstance<UIAtals>();
object[] objs = AssetDatabase.LoadAllAssetsAtPath(path);
atlas.spriteLists.Clear();
foreach (object o in objs)
{
if (o.GetType() == typeof(Texture2D))
{
atlas.mainText = o as Texture2D;
}
else if (o.GetType() == typeof(Sprite))
{
atlas.spriteLists.Add(o as Sprite);
}
}
string[] pathSplit = path.Split('G'); // Modules
path = pathSplit[0] + "Resources/Atlas/" + Selection.activeObject.name.ToLower() + "_Atlas.prefab";
Debug.Log(path);
AssetDatabase.DeleteAsset(path);
AssetDatabase.Refresh();
GameObject go = new GameObject("prefab");
PrefabUtility.SaveAsPrefabAsset(go,path);
AssetDatabase.Refresh();
AssetDatabase.AddObjectToAsset(atlas, path);
AssetDatabase.SaveAssets();
AssetDatabase.Refresh();
DestroyImmediate(go);
}
else
{
EditorUtility.DisplayDialog("", "当前选中的不是图集图片", "确定");
}
}
}
}
这个类内容可批量生成,也可单独生成某一个.生成的atlas放在Resources下.
再给一个读取的方法:
public Dictionary<string, UIAtals> atlasmanage = new Dictionary<string, UIAtals>();
/// <summary>
/// 加载图集
/// </summary>
/// <param name="spriteName">图集名称</param>
public UIAtals LoadAtals(string atlasName)
{
UIAtals atlas = Resources.Load<UIAtals>("Atlas/" + atlasName);
atlasmanage.Add(atlasName, atlas);
return atlas;
}
//加载图集上的一个精灵
public Sprite LoadAtlasSprite(string atlasName, string spriteName)
{
UIAtals atlas;
if (!atlasmanage.ContainsKey(atlasName))
{
atlas = LoadAtals(atlasName);
}
else
{
atlas = atlasmanage[atlasName];
}
if(atlas == null)
{
Log.Error("atlas 不存在,name = " + atlasName);
return null;
}
Sprite sprite = atlas.GetSprite(spriteName);
atlas = null;
return sprite;
}
一套流程如上 运行完全ok
全套代码GitHub上

另做了一个工具,方便程序直接导出美术修改的图片....
