I immediately apologize for my poor English. I hope you agree with me that the collection of equipment in the game is rather scarce. So I decided to try to bring a little joy to the game for myself. Namely, add your model of equipment. Meshfile and textures moved from Blender to Unity and ran into a problem. Yes, I'm new to Unity, but I'm learning. I can't create and package the prefab and assetbundles into a unity3d file. I found a script that creates such a file, but it does not want to work with Unity versions after 2017. I have searched a lot of resources on the internet but have not yet found a solution to this problem. And I need help. Or a hint on how to do it or a link to a resource where I could learn it. Thank you. using UnityEngine;using UnityEditor; public class ExportAssetBundles{[MenuItem("Assets/Build AssetBundle From Selection - Track dependencies")]static void ExportResource (){// Bring up save panelstring path = EditorUtility.SaveFilePanel ("Save Resource", "", "New Resource", "unity3d");if (path.Length != 0){// Build the resource file from the active selection.Object[] selection = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);BuildPipeline.BuildAssetBundle(Selection.activeObject, selection, path, BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets);Selection.objects = selection;}}[MenuItem("Assets/Build AssetBundle From Selection - No dependency tracking")]static void ExportResourceNoTrack (){// Bring up save panelstring path = EditorUtility.SaveFilePanel ("Save Resource", "", "New Resource", "unity3d");if (path.Length != 0) {// Build the resource file from the active selection.BuildPipeline.BuildAssetBundle(Selection.activeObject, Selection.objects, path);}}}
