Hello everyone, I am a Buddhist engineer ☆The Quiet Little Magic Dragon☆ . I update Unity development skills from time to time. If you find it useful, please remember to click three times.

I. Introduction

xdm, Happy National Day. I will study for a while and share a little bit of knowledge with everyone.

ResourcesEveryone should be familiar with the directory. This is a special folder of Unity3D, used to load files.

When building a project, Resourcesall resources and objects in the directory are merged into a serialized file that contains metadata and index information. The index contains a serialized lookup tree that is used to convert the name of a given object. Resolves to its appropriate file GUID and local ID. In this way, it AssetBundleis somewhat similar to .

ResourcesIt is very simple to use, just put the file Resourcesin the folder and then use Resourcesl.Loadload, for example:

void Start()
{
    
    
	Resources.Load("Test");
}

Of course, there are many points to pay attention to when loading, such as backslashes, file types, file suffixes, increased startup time and build time of the application, and the inability to incrementally update, etc.

However, what we are going to discuss today is Resourcesthe loading of folders in different directories.

2. `Resources`Loading in different directories

2-1. Explain before starting

You may ask, Resourcescan it be loaded in other directories? ResourcesWhy put it in different directories?

①Folders Resourcescan also be used in other directories. EditorSimilar to folders, it will be fine if placed in other directories. As long as the file name is this, it can be loaded.

②Why should we put them in different directories? Because if there are multiple colleagues working together on a project, it is inconvenient to manage all the files in the root directory Resourcesbecause we don’t know if other files in this folder are useful. Don't even dare to delete it.

ResourcesCloser to home, how to load files in different directories ?

`Resources`2-1. Loading in different directories

For example, if two colleagues, H and Z, develop the same project and are responsible for developing different scenarios, they each create their own folder in the root directory, and then create a directory under the folder, for example: Scripts in their own folder

. In the folder, create a new script ReLoadTest.cs. Double-click to open the script and edit the code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ReLoadTest : MonoBehaviour
{
    
    
    // Start is called before the first frame update
    void Start()
    {
    
    
        string info = Resources.Load<TextAsset>("loadZ").text;
        Debug.Log(info);
    }

    // Update is called once per frame
    void Update()
    {
    
    

    }
}

Create a loadZ.txt file and type in any content:
Insert image description here
Run the program:

I can also load the contents of the Resources folder in other directories (note the name of the loaded file):

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ReLoadTest : MonoBehaviour
{
    
    
    // Start is called before the first frame update
    void Start()
    {
    
    
        string info = Resources.Load<TextAsset>("loadH").text;
        Debug.Log(info);
    }

    // Update is called once per frame
    void Update()
    {
    
    

    }
}

operation result:
