AB作成

いっつもABのビルド方法忘れて調べるのでメモ

exportとname付け用のscript用意

namespace Sample
{
    public static class AssetBundleBuilder
    {
        [MenuItem("Window/AB/Build")]
        public static void Build()
        {
            var outputDir = "AssetBundleData";
            if (!Directory.Exists(outputDir))
            {
                Directory.CreateDirectory(outputDir);
            }

            BuildPipeline.BuildAssetBundles(
                outputDir,
                BuildAssetBundleOptions.None,
                BuildTarget.StandaloneOSX
            );
        }

        [MenuItem("Window/AB/ApplyName")]
        public static void ApplyName()
        {
            foreach (var o in Selection.objects)
            {
                var path = AssetDatabase.GetAssetPath(o.GetInstanceID());
                var name = Path.GetFileNameWithoutExtension(path);
                AssetImporter importer = AssetImporter.GetAtPath(path);
                importer.assetBundleName = name;
                importer.SaveAndReimport();
            }
        }
    }
}
