Unity之图片压缩，批量设置，导入自动设置

代码如下：

批量设置：

using System.Collections.Generic;
using System.IO;
using UnityEditor;
using UnityEngine;

public class TextureCompressTool : ScriptableObject
{
    [MenuItem("FashionBeat/Compress texture")]
    static void CompressSelectTexture()
    {
        List<string> list = new List<string>();

        foreach (var so in Selection.objects)
        {
            bool isFolder = so is DefaultAsset;
            string selectObjPath = AssetDatabase.GetAssetPath(so);
            if (isFolder)
            {
                string[] files = Directory.GetFiles(selectObjPath, "*.*", SearchOption.AllDirectories);
                for (int i = 0; i < files.Length; i++)
                {
                    string filepath = files[i];
                    if (FBEditorHelper.IsImage(filepath))
                    {
                        string assetpath = FBEditorHelper.GetAssetPath(filepath);
                        if (!list.Contains(assetpath))
                            list.Add(assetpath);
                    }
                }
            }
            else
            {
                if (!list.Contains(selectObjPath))
                    list.Add(selectObjPath);
            }
        }

        for (int i = 0; i < list.Count; i++)
        {
            string assetpath = list[i];
            CompressTexture(assetpath);
            EditorUtility.DisplayProgressBar("批量处理图片", assetpath, (float)i / list.Count);
        }

        EditorUtility.ClearProgressBar();
        AssetDatabase.Refresh();
        Debug.Log("All done, count: " + list.Count);
    }

    static void CompressTexture(string assetpath)
    {
        // 根据路径获得文件目录，设置图集的packagingTag
        TextureImporter textureImporter = AssetImporter.GetAtPath(assetpath) as TextureImporter;
        CompressTexture(textureImporter);
    }

    public static void CompressTexture(TextureImporter textureImporter)
    {
        // 根据路径获得文件目录，设置图集的packagingTag
        if (!textureImporter)
        {
            Debug.LogWarning("textureImporter == null");
            return;
        }
        if (textureImporter.textureType != TextureImporterType.Default)
        {
            Debug.LogWarning("This texture is not Default Type: " + textureImporter.assetPath, textureImporter);
            return;
        }
        bool haveAlpha = textureImporter.DoesSourceTextureHaveAlpha();

        textureImporter.alphaIsTransparency = haveAlpha;
        textureImporter.mipmapEnabled = false;
        textureImporter.isReadable = false;
        textureImporter.textureType = TextureImporterType.Default;
        //textureImporter.wrapMode = TextureWrapMode.Clamp;
        textureImporter.npotScale = TextureImporterNPOTScale.ToNearest;
        textureImporter.textureCompression = TextureImporterCompression.Compressed;

        // Android 端单独设置
        TextureImporterPlatformSettings settingAndroid = new TextureImporterPlatformSettings()
        {
            name = "Android",
            overridden = true,
            format = haveAlpha ? TextureImporterFormat.ETC2_RGBA8 : TextureImporterFormat.ETC_RGB4,
        };
        textureImporter.SetPlatformTextureSettings(settingAndroid);

        // IOS端单独设置
        TextureImporterPlatformSettings settingIOS = new TextureImporterPlatformSettings()
        {
            name = "iOS",
            overridden = true,
            format = TextureImporterFormat.ASTC_6x6,
        };
        textureImporter.SetPlatformTextureSettings(settingIOS);

        textureImporter.SaveAndReimport();

        Debug.Log("Compress texture done: " + textureImporter.assetPath);
    }

}

导入自动设置：

using UnityEditor;
using UnityEngine;

public class AssetImporterProcessor : AssetPostprocessor
{
    void OnPostprocessTexture(Texture2D texture)
    {
        TextureCompressTool.CompressTexture(assetImporter as TextureImporter);
    }
}
