Специальные Папки Проекта
You can usually choose any name you like for the folders you create to organise your Unity project. However, there are a number of folder names that Unity interprets as an instruction that the folder’s contents should be treated in a special way. For example, you must place Editor scripts in a folder called Editor for them to work correctly.
This page contains the full list of special folder names used by Unity.
Папка Assets - главная папка в которой содержатся все ассеты, которые могут быть использованы проектом на Unity. Содержимое Project view соответствует содержимому папки Assets. Большинство функций API предполагают что всё содержится в папке Assets и не требуют явного указания расположения. Однако есть некоторые функции которым нужно явно указывать папку Assets (напр. некоторые функции класса AssetDatabase).
Scripts placed in a folder called Editor are treated as Editor scripts rather than runtime scripts. These scripts add functionality to the Editor during development, and are not available in builds at runtime.
You can have multiple Editor folders placed anywhere inside the Assets folder. Place your Editor scripts inside an Editor folder or a subfolder within it.
The exact location of an Editor folder affects the time at which its scripts will be compiled relative to other scripts (see documentation on Special Folders and Script Compilation Order for a full description of this). Use the EditorGUIUtility.Load function in Editor scripts to load Assets from a Resources folder within an Editor folder. These Assets can only be loaded via Editor scripts, and are stripped from builds.
Note: Unity does not allow components derived from MonoBehaviour to be assigned to GameObjects if the scripts are in the Editor folder.
Editor scripts can make use of Asset files loaded on-demand using the EditorGUIUtility.Load function. This function looks for the Asset files in a folder called Editor Default Resources.
You can only have one Editor Default Resources folder and it must be placed in the root of the Project; directly within the Assets folder. Place the needed Asset files in this Editor Default Resources folder or a subfolder within it. Always include the subfolder path in the path passed to the EditorGUIUtility.Load function if your Asset files are in subfolders.
Gizmos allow you to add graphics to the Scene View to help visualise design details that are otherwise invisible. The Gizmos.DrawIcon function places an icon in the Scene to act as a marker for a special object or position. You must place the image file used to draw this icon in a folder called Gizmos in order for it to be located by the DrawIcon function.
You can only have one Gizmos folder and it must be placed in the root of the Project; directly within the Assets folder. Place the needed Asset files in this Gizmos folder or a subfolder within it. Always include the subfolder path in the path passed to the Gizmos.DrawIcon function if your Asset files are in subfolders.
You can add plug-ins to your Project to extend Unity’s features. Plug-ins are native DLLs that are typically written in C/C++. They can access third-party code libraries, system calls and other Unity built-in functionality. Always place plug-ins in a folder called Plugins for them to be detected by Unity.
You can only have one Plugins folder and it must be placed in the root of the Project; directly within the Assets folder.
See Special folders and script compilation order for more information on how this folder affects script compilation, and Plugin Inspector for more information on managing plug-ins for different target platforms.
You can load Assets on-demand from a script instead of creating instances of Assets in a Scene for use in gameplay. You do this by placing the Assets in a folder called Resources. Load these Assets by using the Resources.Load function.
You can have multiple Resources folders placed anywhere inside the Assets folder. Place the needed Asset files in a Resources folder or a subfolder within it. Always include the subfolder path in the path passed to the Resources.Load function if your Asset files are in subfolders.
Note that if the Resources folder is an Editor subfolder, the Assets in it are loadable from Editor scripts but are stripped from builds.
Когда вы импортируете какой-либо стандартный пакет с ассетами (menu: Assets > Import Package) ассеты пакета размещаются в папке Standard Assets или Pro Standard Assets в случае если пакет доступен только для Про лицензии. Помимо того что папки содержат ассеты, они также влияют на порядок компиляции скриптов. Подробности смотри на странице Специальные Папки и Порядок Компиляции Скриптов.
You can only have one Standard Assets folder and it must be placed in the root of the Project; directly within the Assets folder. Place the needed Assets files in this Standard Assets folder or a subfolder within it.
You may want the Asset to be available as a separate file in its original format although it is more common to directly incorporate Assets into a build. For example, you need to access a video file from the filesystem rather than use it as a MovieTexture to play that video on iOS. Place a file in a folder called StreamingAssets, so it is copied unchanged to the target machine, where it is then available from a specific folder. See the page about Streaming Assets for further details.
You can only have one StreamingAssets folder and it must be placed in the root of the Project; directly within the Assets folder. Place the needed Assets files in this StreamingAssets folder or a subfolder within it. Always include the subfolder path in the path used to reference the streaming asset if your Asset files are in subfolders.
During the import process, Unity completely ignores the following files and folders in the Assets folder (or a sub-folder within it):
This is used to prevent importing special and temporary files created by the operating system or other applications.
