Unity 2021.3.33f1

----

앱 최초 실행 시, 최적화를 위해 그래픽 품질 관련 자동 설정하는 기능을 찾아보다 적용하고 올려 둠.

참조한 글을 보니 기본적으로 유니티 SystemInfo에서 지원하는 하드웨어 스펙을 보고 판단해서 Quality Level을 메기고 있다.

해당 레벨은 Unity의 UnityEngine.QualityLevel을 참조하고 있어서 대응 하는 enum을 추가(eQualityLevel)하고,

60프레임을 사용하기 위해 해당 부분 값만 수정했다.

필요할 때 AutoChooseQualityLevel()을 호출하고, 반환 받은 eQualityLevel 값에 따라 원하는 설정을 적용해주면 된다.

/// <summary>
/// UnityEngine.QualityLevel에 대응하는 enum
/// </summary>
public enum eQualityLevel : int 
{
    Fastest,
    Fast,
    Simple,
    Good,       // [참고] PC(i7-10700/64GB/RTX3700)에서 Good 나옴
    Beautiful,
    Fantastic
}

private eQualityLevel AutoChooseQualityLevel()
{
    Debug.Assert(Enum.GetNames(typeof(QualityLevel)).Length == Enum.GetNames(typeof(eQualityLevel)).Length, "Please update eQualityLevel to the new quality levels.");

	var shaderLevel = SystemInfo.graphicsShaderLevel;
    var cpus = SystemInfo.processorCount;
    var vram = SystemInfo.graphicsMemorySize;
    var fillrate = 0;

    // ShaderLevel
    if (shaderLevel < 10)
    	fillrate = 1000;
    else if (shaderLevel < 20)
    	fillrate = 1300;
    else if (shaderLevel < 30)
    	fillrate = 2000;
    else
    	fillrate = 3000;
    // CPU Count
    if (6 <= cpus)
    	fillrate *= 3;
    else if (3 <= cpus)
    	fillrate *= 2;
    // VRam
    if (512 <= vram)
    	fillrate *= 2;
    else if (vram <= 128)
    	fillrate /= 2;
        
    var resx = Screen.width;
    var resy = Screen.height;
    var target_fps = 60.0f;		// 현재 게임의 타겟 프레임에 맞게 설정
    var fillneed = (resx * resy + 400f * 300f) * (target_fps / 1000000.0f);
    // Change the values in levelmult to match the relative fill rate
    // requirements for each quality level.
    var levelmult = new float[] { 5.0f, 30.0f, 80.0f, 130.0f, 200.0f, 320.0f };

    const int max_quality = (int)eQualityLevel.Fantastic;
    var level = 0;
    while (level < max_quality && fillneed * levelmult[level + 1] < fillrate)
        ++level;

    var quality = (eQualityLevel)level;
    Debug.Log(string.Format("{0}x{1} need {2} has {3} = {4} level", resx, resy, fillneed, fillrate, quality.ToString()));

    return quality;
}

P.s. 참조 글 중에 에셋도 적혀있긴한데 사서 써보진 않음.

유니티 (Unity)에서 멀티 키 딕셔너리 (Multi Key Dictionary)를 사용하는 방법에 대해 검색 결과를 제공해드리겠습니다.

멀티 키 딕셔너리는 두 개 이상의 키로 값을 저장하고 검색할 수 있는 자료구조입니다. 유니티에서는 기본적으로 이러한 기능을 제공하지 않지만, 다음과 같은 방법을 사용하여 멀티 키 딕셔너리를 구현할 수 있습니다:

Tuple을 사용한 멀티 키 딕셔너리 구현: Tuple을 이용하여 여러 키를 하나의 키로 묶고, 해당 키에 대한 값을 딕셔너리에 저장하는 방식입니다. 이렇게 하면 여러 키로 값을 조회하거나 저장할 수 있습니다.

using System;
using System.Collections.Generic;

public class MultiKeyDictionary<TKeyTuple, TValue>
{
    private Dictionary<TKeyTuple, TValue> dictionary = new Dictionary<TKeyTuple, TValue>();

    public void Add(TKeyTuple keys, TValue value)
    {
        dictionary[keys] = value;
    }

    public bool TryGetValue(TKeyTuple keys, out TValue value)
    {
        return dictionary.TryGetValue(keys, out value);
    }
}

// 사용 예시
var multiKeyDict = new MultiKeyDictionary<(int, string), int>();
multiKeyDict.Add((1, "key1"), 100);
multiKeyDict.Add((2, "key2"), 200);

if (multiKeyDict.TryGetValue((1, "key1"), out int result))
{
    Debug.Log("Value found: " + result);
}

C# 9의 init-only 프로퍼티와 튜플 사용: C# 9부터 init-only 프로퍼티를 사용하여 딕셔너리의 값을 읽기 전용으로 설정하고, 튜플을 활용하여 멀티 키를 표현할 수 있습니다.

using System;
using System.Collections.Generic;

public class MultiKeyDictionary<TValue>
{
    private Dictionary<(int, string), TValue> dictionary = new Dictionary<(int, string), TValue>();

    public void Add(int key1, string key2, TValue value)
    {
        dictionary[(key1, key2)] = value;
    }

    public IReadOnlyDictionary<(int, string), TValue> Dictionary => dictionary;
}

// 사용 예시
var multiKeyDict = new MultiKeyDictionary<int>();
multiKeyDict.Add(1, "key1", 100);
multiKeyDict.Add(2, "key2", 200);

if (multiKeyDict.Dictionary.TryGetValue((1, "key1"), out int result))
{
    Debug.Log("Value found: " + result);
}

이렇게 유니티에서 멀티 키 딕셔너리를 구현할 수 있습니다. 코드는 예시일 뿐이며, 실제 프로젝트에서 적절한 방식으로 적용하셔야 합니다.

사용법 :

CoroutineHelper.StartCoroutine(코루틴_함수());

CoroutineHelper.StopCoroutine(코루틴);

그냥 유니티 생명주기를 가진 한 싱글톤 객체에 코루틴 실행을 몰아주는 방식

가끔 MonoBehaviour 상속 안 받고 코루틴 실행하고 싶을 때가 있는데 그럴때 사용할 수 있을듯..

예전에 unirx(MainThreadDispatcher)한 번 사용해본적 있었는데 거기서 아이디어 얻음

[링크3] https://github.com/Mokbii/CSharpSyncRandom/tree/master/SyncRandomTest

이번에는 HTTP 서버에 데이터 요청을 보내고 데이터를 얻어오기, 혹은 데이터를 보내는 방법입니다.

목차

1. WWW 클래스로 구현(권장하지 않습니다.)

2-1. Get 방식

2-2. Post 방식

2. UnityWebRequest 클래스로 구현(권장)

2-1. Get 방식

2-2. Post 방식

3. 요약 및 정리

1. WWW 클래스로 구현

​

1-1 GET 방식

아래는 제가 작성한 간단한 GET 방식의 코드입니다.

GET 방식 테스트를 위해 이곳을 이용하겠습니다.

https://developers.neople.co.kr/contents/apiDocs

APIKey는 로그인을 하시고 발급받으시면 보입니다.

​

응답 요청은 코루틴을 이용해서 보내도록 하겠습니다.

코루틴을 이용하는 이유는 응답을 보내고 오는 시간이 걸리기 때문입니다.

다른 곳에서 작성하시면 응답이 오기 전에 처리하게 되어 오류가 출력됩니다.

위에 코드는 예시 코드입니다.

홈페이지에서 발급받은 apikey를 저기에 입력하시면 됩니다.

url을 보시면 servers? apikey=하고 요청을 보내게 되는데

헤더 부분에 정보를 넣어서 보내는 곳이 저곳입니다.

코드에 주석을 넣었으니 읽으면서 확인해보세요.

코드를 실행해보시면 이렇게 응답이 옵니다.

​

1-2 POST 방식

위에는 POST 방식입니다.

POST 방식은 따로 동작을 처리해야 하기 때문에 개인적으로 만든 서버를 이용하여 설명하겠습니다.(저건 사설 ip 주소이기 때문에 똑같이 적으셔도 동작 안 합니다.)

(테스트해보고 싶으신 분들은 따로 서버를 만드셔서 실험해보세요)

​

POST 방식은? apikey= 이런 게 없습니다.

필드명에 apikey를 넣고 데이터를 넣으시면 됩니다.

필요한 내용은 주석 처리했습니다.

서버에서 로그인 정보가 맞으면 응답을 보냅니다.

​

2. unitywebrequest 클래스

이제 www 클래스는 Unity에서 사용을 권장하지 않습니다.

사용하시면 주의로 unitywebrequest를 사용하라고 나올 텐데요.

이것을 사용하는 방법을 알려드리겠습니다.

​

UnityEngine.Networking을 추가해줍니다.

​

2-1 GET 방식

아래는 WWW 클래스를 UnityWebRequest 클래스 방식으로 수정한 것입니다.

수정한 부분은 빨간 줄로 밑줄을 쳤습니다.

2-2 POST 방식

수정한 부분은 밑줄 쳤습니다.

3. 요약 및 정리

정리 : 통신방식에는 GET과 POST가 있다.

GET은 쉬우나 보안 취약, 용량 제한

POST는 어려우나 보안에 좋고, 용량 제한이 없다.

WWW 클래스는 이제 사용하지 않는다.

UnityWepRequest를 사용하자.(설명은 WWW 클래스에 적어놓았다.)
