Project

描述

Use this API to perform searches in the Project. Engines for this type of search implement the IProjectSearchEngine interface.

Registered Project engines are called during searches in the Project browser. When the default object selector is used, they are also called for Asset searches.

The following example creates a Project engine:

using System;
using System.Collections.Generic;
using System.Linq;
using UnityEditor;
using UnityEditor.SearchService;
using UnityEngine;
using Object = UnityEngine.Object;

[ProjectSearchEngine]
class TestProjectSearchEngine : IProjectSearchEngine
{
    public string name => "My Custom Engine";

    public void BeginSession(ISearchContext context)
    {
    }

    public void EndSession(ISearchContext context)
    {
    }

    public void BeginSearch(ISearchContext context, string query)
    {
    }

    public void EndSearch(ISearchContext context)
    {
    }

    public IEnumerable<string> Search(ISearchContext context, string query, Action<IEnumerable<string>> asyncItemsReceived)
    {
        var allPaths = AssetDatabase.GetAllAssetPaths();
        var filteredPaths = allPaths.Where(path => !path.StartsWith("Library")).Where(path => path.IndexOf(query, StringComparison.InvariantCultureIgnoreCase) >= 0).ToList();
        return filteredPaths;
    }
}
