기본적으로 어떤 카메라에도 보이지 않는 스킨드 메시는 업데이트 되지 않습니다. 메시가 스크린에 다시 나타날 때까지 스키닝은 업데이트 되지 않습니다. 이는 시스템을 절약하기 위해서입니다.
오브젝트의 가시성은 메시의Bounds에서 결정됩니다(전체 바운딩 영역은 모든 활성화된 카메라의 뷰 밖에 있어야 합니다). 하지만 애니메이션 메시의 트루 바운딩 영역은 애니메이션이 재생되면서 변경될 수 있습니다(예를 들어 캐릭터가 공중으로 손을 들어 올리면 영역은 커집니다). Unity는 최대 바운딩 영역을 계산할 때 첨부된 모든 애니메이션을 고려하지만 일어날 만한 모든 경우를 예측하기 위해 바운드를 계산할 수 없는 경우도 존재합니다.
다음의 각 예제 상황은 뼈대나 버텍스를 미리 계산된 바운딩 영역 밖으로 밀어낼 때 문제가 됩니다.
런타임에 애니메이션이 추가된 경우
추가 애니메이션
스크립트에서 뼈대의 포지션을 순서대로 바꿀 때
버텍스를 미리 계산된 바운드 바깥으로 밀어내는 버텍스 셰이더를 사용할 때
래그돌을 사용하는 경우
이런 문제에는 두 가지 해결책이 있습니다.
바운드를 수정해 메시의 잠재적 바운딩 영역을 일치시키기
Update When Offscreen을 활성화해 스킨드 메시를 항상 스킨 및 렌더링합니다.
일반적으로 퍼포먼스가 더 나은 첫 번째 옵션을 사용해야 합니다. 하지만 퍼포먼스가 주요 관심사가 아니거나 (래그돌을 사용할 때처럼)바운딩 영역의 크기를 예측할 수 없는 경우에 두 번째 옵션을 추천합니다.
스킨드 메시가 래그돌과 더 잘 작동하기 위해 Unity는 임포트할 때 스킨드 메시 렌더러를 루트 뼈대에 자동으로 리맵합니다. 하지만 이는 모델 파일에 스킨드 메시 렌더러가 하나일 때만 해당됩니다. 이는 스킨드 메시 렌더러 전체를 루트 뼈대이나 자식에 첨부하지 못하고 래그돌을 사용하면 이 최적화를 해제해야 함을 뜻합니다.

Using the shortcutAlt + 'or theHelp -> Quick Searchmenu will bring out the Quick Search Tool. This extensible tool allows you to search over multiple area of Unity.
It is easy to add new search providers to the Quick Search Tool (see API section below), by default we ship with theseSearchProviders:
Assets
All assets in the current project are available for search. From an asset you can apply the following actions:
Select the asset (in the Project browser)
Open the asset (using an external editor if necessary)
Show in Explorer (Finder)
Asset provider supports advance type filtering (Similar to Project Hierarchy):
Current Scene
All GameObjects in the current scene are available for search. Activating a scene item in the Quick Search tool will select the corresponding GameObject in the Scene.
Menu
Each menu items in Unity is available for search. You can execute the menu item from the Quick Search Tool. This is especially useful to pop that elusive Test Runner or the Profiler!
Settings
Each Project Settings or Preferences pages is available for search. The Quick Search Tool will open the Unified Settings Window at the required pages.
Online Search Providers
We have aSearchProviderthat allows to search various Unity websites. Using this provider will open your default browser at a specific Unity page and perform a search and display some results. You can search the following websites and it is very easy to add new web search providers:
All the features of the Quick Search tool can be access using the keyboard:
The Search box is always focused and you can type even with an element selected.
Alt + Left Arrow: Toggle the Filter view

Alt + Right Arrowbrings the action menu

Filters
There are 2 levels of filtering available in the Quick Search Tool:
Provider filters
Those filters define which providers are available for a search. This can help reduce the amount of items return by a search query especially if you know what type of item you are looking for.
Note that there are more specialized shortcuts to call the Quick Search Tool with a specific provider filter enabled:
Alt + Shit + A: Assetsonlysearch
Alt + Shit + M: Menuonlysearch
Alt + Shit + S: Sceneonlysearch
Provider text filters
From the Quick Search Box you can type a searchprovider search filter tokenthat will restrain the search to specific providers. The search tokens are:
Asset:p:
Menu:me:
Scene:h:
Online Search:web:
Example of queries using text providers:
p:Player: Search assets containing "Player"
h:Main Camera: Search scene for GameObjects with "Main Camera" in their name
me:Test Runner: Search menus item for Test Runner
se:VFX: Search settings (project and preferences) for VFX
Provider specific filters
Some provider (i.e the Asset provider) supports specific filters:
As usual you can pass the same search tokens used by the project browser to a search query:
Last Search
When opening the Quick Search Tool usingAlt + `the state (and filters) of your previous search is preserved:
Drag and Drop
Asset items and Scene Items supports drag and drop from the QuickSearch window to anywhere that supports it (hierarchy view, game view, inspector, etc):
API
Creating newSearchProvideris fairly easy. It basically comes down to providing a function to fetch and search for items and to provide action handlers toactivateany selected item.
SearchProvider
AnSearchProvidermanages search for specific type of items and manages thumbnails, description and subfilters. Its basic API is as follow:
public class SearchProvider
{
public SearchProvider(string id, string displayName = null);
// Create an Item bound to this provider.
public SearchItem CreateItem(string id, string label = null, string description = null, Texture2D thumbnail = null);
// Utility functions use to check if a search text matches a string.
public static bool MatchSearchGroups(string searchContext, string content);
public static bool MatchSearchGroups(string searchContext, string content, out int startIndex, out int endIndex);
public NameId name;
// Text filter key use to enable this Provider from the NameId search box
public string filterId;
// Functor used to fetch item description
public DescriptionHandler fetchDescription;
// Functor used to fetch thumbnail icon
public PreviewHandler fetchThumbnail;
// Functor used to execute a search query
public GetItemsHandler fetchItems;
// Functor use to check if an item is still valid
public IsItemValidHandler isItemValid;
// Sub filter specific to this provider
public List<NameId> subCategories;
// Called when QuickSearchWindow is opened allowing a provider to initialize search data.
public Action onEnable;
// Called when QuickSearchWindow is closed.
public Action onDisable;
}
Note that since the UI of the NameId is done using avirtual scrolling algorithmsomeSearchItemfields (thumbail and description) are fetched on demand. This means theSearchProviderneeds to be initialized with specificHandlers(fetchDescription, fetchThumbnail) if you want to populate those fields.
Registering an SearchProvider
Adding a newSearchProvideris just creating a function tagged with the[SearchItemProvider]attribute. This function must returns a newSearchProviderinstance:
By default anSearchProvidermust have a type (ex: asset, menu, scene...) that is unique among providers and a display Name (used in the Provider filter dialog).
Specifying afilterIdis optional but it makestext based filteringeasier (ex:p: my_asset).
Performing a search
The bulk of the provider work happens in thefetchItemsfunctor. This is the function a provider creator must fulfill to do an actual search (and filtering). ThefetchItemssignature is:
// context: all the necessary search context (tokenized search, sub filters...)
// items: list of items to populate
// provider: the provider itself
public delegate void GetItemsHandler(SearchContext context, List<SearchItem> items, SearchProvider provider);
TheSearchProvidermust add newSearchItems to theitemslist.
AnSearchItemis a simple struct:
public struct SearchItem
{
// Unique id of this item among this provider items.
public string id;
// Display name of the item
public string label;
// If no description is provided, SearchProvider.fetchDescription will be called when the item is first displayed.
public string description;
// If no thumbnail are provider, SearchProvider.fetchThumbnail will be called when the item is first displayed.
public Texture2D thumbnail;
}
Only theidis necessary to be filled.
When doing filtering according toSearchContext.searchTextwe recommend using the static functionSearchProvider.MatchSearchGroupwhich makes partial search (and eventually fuzzy search) easy (see example above).
Asynchronous Search Results
If your search providers can take a long time to compute its results or rely on asynchronous search engine (ex: WebRequests) you can use thecontext.sendAsyncItemscallback to populate search results asynchronously.
TheSearchContextalso contains asearchIdthat needs to be provided with the call tosendAsyncItems. This allows QuickSearch to know for which search those results are provided.
An example of using asynchronous search result would be:
new SearchProvider(type, displayName)
{
filterId = "store:",
fetchItems = (context, items, provider) =>
{
var currentSearchRequest = UnityWebRequest.Get(url + context.searchQuery);
currentSearchRequest.SetRequestHeader("X-Unity-Session", InternalEditorUtility.GetAuthToken());
var currentSearchRequestOp = currentSearchRequest.SendWebRequest();
currentSearchRequestOp.completed += op => {
var items = // GetItems from websearch
// Notify the search about async items:
// ensure to set the searchId you are providing result for!
context.sendAsyncItems(context.searchId, items);
};
}
};
The QuickSearch package contains 2 examples with async results:
com.unity.quicksearch/Editor/Providers/Examples/AssetStoreProvider.cs: which provide a way to query the asset store using WebRequest.
com.unity.quicksearch/Editor/Providers/Examples/ESS.cs: which creates a thread to start the EntrianSource search indexer to provide full text search for assets in your project.
Registering an Action Handler
Actions can be register for a specific provider. These actions buttons will be drawn next to theSearchItemof the specified provider type:
Since registering an action handler is a different process than regisering a provider this means you can register new action handlers for existing providers (mind blown)!
Here is an example of how to register actions for the Asset provider:
Basically you create a function tagged with the[SearchActionsProvider]attribute. This function must returns anIEnumerable<SearchAction>.
AnSearchActiondescribe and action and provide a handler to execute the action on a specificSearchItem
public class SearchAction
{
public SearchAction(string providerType, string name, Texture2D icon = null, string tooltip = null);
public ActionHandler handler;
public EnabledHandler isEnabled;
}
providerTypeis the provider unique id for which you are registering the action.
ActionHandleris of the following signature:
// item: item that needs the action to be executed.
// context: search context of the SearchTool when the item is executed.
public delegate void ActionHandler(SearchItem item, SearchContext context);
An action can be setup with aisEnabledpredicate that will decide if the action is available (i.e. enabled) for a specific item.
SearchService
TheSearchServicemanages most of the persisted state of the Quick Search Tool and provider a global end point to access the filter.
The common usage of theSearchServiceforSearchProviderwriter is to register a shortcut that will open the Quick Search Tool with a specific set of filter enabled:
[Shortcut("Window/Quick Search Tool/Assets", KeyCode.A, ShortcutModifiers.Alt | ShortcutModifiers.Shift)]
public static void PopQuickSearch()
{
// Disable all filter
SearchService.Filter.ResetFilter(false);
// Enabled only the asset SearchProvider
SearchService.Filter.SetFilter(true, "asset");
// Disabled the packages sub filter
SearchService.Filter.SetFilter(false, "asset", "a:packages");
// Open the Quick Search Tool to allow a quick search of assets!
SearchTool.ShowWindow();
}
