public static string[] FindAssets (string filter);
public static string[] FindAssets (string filter, string[] searchInFolders);

パラメーター

filterThe filter string can contain search data. See below for details about this string.
searchInFoldersThe folders where the search will start.

戻り値

string[] Array of matching asset. Note that GUIDs will be returned.

説明

Search the asset database using the search filter string.

FindAssets allows you to search for Assets. The string argument can provide names, labels or types (classnames). The filter string can include:

Name: Filter assets by their filename (without extension). Words separated by whitespace are treated as a separate name searches. So, for example "test asset", is a name of an Asset which will be searched for. Note that name: can be used to identify an asset. Further, the name used in the filter string can be specified as a subsection. For example the test asset example above can be matched using test.

Labels: Assets can have labels attached to them. Assets with particular labels can be found use the keyword 'l:' before each label. This indicates that the string is searching for labels.

Types: Find assets based on explicitly identified types. The keyword 't:' is used as a way to specify that typed assets are being looked for. If more than one type is included in the filter string then assets that match one class will be returned. Types can either be builtin types such as Texture2D or user created script classes. User created classes are assets created from a ScriptableObject class in the project. If all assets are wanted use Object as all assets derive from Object. Specifying one or more folders using the searchInFolders argument will limit the searching to these folders and their child folders. This is faster than searching all assets in all folders.

Note: Searching is case insensitive.

Use AssetDatabase.GUIDToAssetPath to get asset paths and AssetDatabase.LoadAssetAtPath to load an asset.

using UnityEngine;
using UnityEditor;

public class Example { [MenuItem("Example/FindAssets Example")] static void ExampleScript() { // Find all assets labelled with 'architecture' : string[] guids1 = AssetDatabase.FindAssets("l:architecture", null);

foreach (string guid1 in guids1) { Debug.Log(AssetDatabase.GUIDToAssetPath(guid1)); }

// Find all Texture2Ds that have 'co' in their filename, that are labelled with 'architecture' and are placed in 'MyAwesomeProps' folder string[] guids2 = AssetDatabase.FindAssets("co l:architecture t:texture2D", new[] {"Assets/MyAwesomeProps"});

foreach (string guid2 in guids2) { Debug.Log(AssetDatabase.GUIDToAssetPath(guid2)); } } }

The following script example shows how the Names, Labels and Types details added to Assets can be located. The FindAssets function is demonstrated. The assets created in this example use the ScriptObj class.

// This script file has two CS classes.  The first is a simple Unity ScriptableObject script.
// The class it defines is used by the Example class below.
// (This is a single Unity script file. You could split this file into a ScriptObj.cs and an
// Example.cs file which is more structured.)

using UnityEngine; using UnityEditor;

public class ScriptObj : ScriptableObject { public void Awake() { Debug.Log("ScriptObj created"); } }

// Use ScriptObj to show how AssetDabase.FindAssets can be used
