Unity Addressable Asset system | Addressables | 1.18.15

 

튜토리얼

 

1. 새로운 프로젝트를 생성

 

2. Sprite Packer 확인 (Edit/Project Settings/Editor 에서 Sprite Packer/Mode Always Enabled)

 

3. 에디터의 Window/Package Manager 로 들어가서 Addressables 를 설치

 

4. Window/Asset Management/Addressables/Group 실행 후 Create Addressables Settings 클릭

 

5.  아틀라스 생성

저는 이미지 폴더안에 아이콘들만 모아둘 폴더를 생성했습니다

Icon 폴더랑 같은 위치에 Create 로 Sprite Atlas 를 생성

표시한 부분을 잘 보고 값을 입력하시고.. 아래 폴더째로 넣은 것에 주의.. 폴더를 드래그 해서 올리면 됩니다

 

6. 확인하기 위해 UGUI 생성

그냥 UI 에서 이미지를 하나 생성 합니다

7. Image 에 아래 소스로 컴포넌트를 부착

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.AddressableAssets;

public class Test_AddresAtlas : MonoBehaviour
{
    [SerializeField] protected Image m_Image;

    // Start is called before the first frame update
    IEnumerator Start()
    {
        yield return Addressables.InitializeAsync();

        string atlasName = "Atlas_Icon";
        string imageName = "emoticon_001";
        var handle = Addressables.LoadAssetAsync<Sprite>($"{atlasName}[{imageName}]"); // Atlas_Icon[emoticon_001]

        yield return handle;

        m_Image.sprite = handle.Result;
        
        Addressables.Release(handle);
    }
}

 

 

8. 이런.. 애러가 발생하는군요.. 스프라이트를 찾지 못하고 있어요 -_- 아마

 도 이 게시물에 온 이유중 가장 많은 이유가 이거겠죠..

9. 애러 해결

최초 올렸던 이미지의 속성으로 가서 Texture 타입을 봅시다 -_-;;; 스프라이트로 안되어있으니 스프라이트 아틀라스로 들어가지 않았고 들어가지 않았으니 못찾는게 당연한;;

10. 결과

잘 나오는군요

 

 

11. 기타

using UnityEngine.AddressableAssets;

    if(!handle.IsDone)
        yield return handle;

    if (handle.Status == AsyncOperationStatus.Succeeded)
    {
        Texture2D texture = handle.Result;
