批量工具-设置图片属性

使用UGUI开发,导入图片时,总是要设置图片的属性(tag,spriteMode,alpha….)很是机械繁琐操作,OnPreprocessTexture()可自动;SetImgProperty()可手动

public class OutPullImgAutoSetting : AssetPostprocessor
{
    /// 

    /// 导入时自动设置属性--1.copy到文件夹下都会自动设置的  
    ///2.拖入到u3d中也会自动设置---,此方法有点无赖,最好使用时才打开,因为有些图片要其他格式也会设置成这格式
    /// 
    void OnPreprocessTexture()
    {
        /*
    //自动设置类型;  
        TextureImporter imgPNG = (TextureImporter)assetImporter;
        imgPNG.textureType = TextureImporterType.Sprite;
        imgPNG.spriteImportMode = SpriteImportMode.Single;

        string dirName = System.IO.Path.GetDirectoryName(assetPath);
        imgPNG.spritePackingTag = System.IO.Path.GetFileName(dirName);        //自动设置打包tag;  
        imgPNG.sRGBTexture = true;
        imgPNG.alphaIsTransparency = true;
        imgPNG.mipmapEnabled = false;
        imgPNG.wrapMode = TextureWrapMode.Clamp;
        imgPNG.SetPlatformTextureSettings("iPhone", 2048, TextureImporterFormat.RGBA32);
        imgPNG.SetPlatformTextureSettings("Android", 2048, TextureImporterFormat.ETC2_RGBA8);
        //   Debug.Log("Set Packing Tag 导入图片自动设置图片属性---  " + folderStr + "  " + dirName + "  " + dirName);
    */
    }

    /// 

    /// 手动批量设置图片属性 project里的目录--可见下面的扩展
    /// 
    [MenuItem("SpritesPacker/_UI批量改属性-目录自己手动改下路径--别乱点")]
    public static void SetImgProperty()
    {
        return;//用时再打开
        DirectoryInfo uiStickers = new DirectoryInfo(Application.dataPath + "/Art/UI/Stickers");
        foreach (DirectoryInfo item in uiStickers.GetDirectories())//记住 uiStickers目录下 两级目录
        {
            foreach (FileInfo pngItem in item.GetFiles("*.png", SearchOption.AllDirectories))
            {
                string allPath = pngItem.FullName;
                string temp_assetPath = allPath.Substring(allPath.IndexOf("Assets"));
                TextureImporter imgPNG = AssetImporter.GetAtPath(temp_assetPath) as TextureImporter;
                imgPNG.textureType = TextureImporterType.Sprite;
                imgPNG.spriteImportMode = SpriteImportMode.Single;
                //自动设置打包tag; 
                string dirName = Path.GetDirectoryName(allPath);
                imgPNG.spritePackingTag = Path.GetFileName(dirName);

                imgPNG.sRGBTexture = true;
                imgPNG.alphaIsTransparency = true;
                imgPNG.mipmapEnabled = false;
                imgPNG.wrapMode = TextureWrapMode.Clamp;
                imgPNG.SetPlatformTextureSettings("iPhone", 2048, TextureImporterFormat.RGBA32);
                imgPNG.SetPlatformTextureSettings("Android", 2048, TextureImporterFormat.ETC2_RGBA8);
            }
        }
    }
}

扩展:有可n个文件夹,遍历下,可操作性强点
