【ChatGPT 】How to use a chat function from API with Python?

KENTO⚽️XR Engineer😎 — Mon, 08 May 2023 06:28:53 +0000

Environment

MacOS
MacBook Pro (M2 chip)

Step 1: Set Up Account

First step, you have to set up and make contract your account.
https://platform.openai.com/overview

Pricing is a below link.
https://openai.com/pricing

Step 2: Set Up Python

Install command.

$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
$ python3 get-pip.py

Write .zshrc.

$ vi ~/.zshrc

Pressed i is entering an insert mode and finish edit Esc, exit is :wq)

alias pip='pip3'

Apply .zshrc.

$ source ~/.zshrc

If successful, you will be able to use pip command.

Step 3: Set Up OpenAI

Install command.

$ pip install openai

Step 4: Fix environment

I faced a problem about this error.

urllib3 v2.0 only supports OpenSSL 1.1.1+, currently the 'ssl' module is compiled with LibreSSL 2.8.3. See: https://github.com/urllib3/urllib3/issues/2168

I've tried two approaches, changing ssh and downgrading the module.

Changing ssh command.

$ brew install openssl
$ echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

If you can't use brew command although it have already installed, change "using Rosetta" on terminal. (You can change it on tarminal info from opening Finder)

Changing urllib3 version command.

$ pip install urllib3==1.25.11

Step 5: Run sample Code


import openai
openai.api_key = "sk-***********************************"

content = ''' You roleplay as the know-it-all, talkative Johnson.
              Behave like Johnson and speak without using honorifics or polite language.
              Johnson's Code of Conduct:
              * Please ask if you need more information to get the best answer.
              * Don't repeat what the user said.'''

res = openai.ChatCompletion.create(
   model="gpt-3.5-turbo",
   messages=[
       {
           "role": "system",
           "content": content
       },
       {
           "role": "user",
           "content": "Who are you？"
       }
   ],
)
print(res)
print(res["choices"][0]["message"]["content"])

【Unity】A script for easier scenes debugging in Unity Editor

KENTO⚽️XR Engineer😎 — Mon, 24 Apr 2023 04:00:41 +0000

Intro

I recommend to create a script for debug at first on creating a new Unity project. It costs you at first, but the benefits will pay off over time.

This time I will write in this article how to display all scenes for debugging.

Demo

A script can easily display all scenes in a project, like this:

Sample Code


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

public class DisplayDebugScene : MonoBehaviour
{
    private List<string> _sceneNameList;

    private static DisplayDebugScene _instance;

    private void Awake()
    {
        if (_instance != null)
        {
            Destroy(_instance);
            return;
        }

        _instance = this;
        DontDestroyOnLoad(_instance);

        _sceneNameList = new List<string>();
        for (int i = 1; i < SceneManager.sceneCountInBuildSettings; i++)
        {
            var path = SceneUtility.GetScenePathByBuildIndex(i);
            var sceneName = path.Substring(0, path.Length - 6).Substring(path.LastIndexOf('/') + 1);
            _sceneNameList.Add(sceneName);
            Debug.Log(sceneName);
        }
    }

    private void OnGUI()
    {
        foreach (var sceneName in _sceneNameList)
        {
            if (GUILayout.Button(sceneName))
            {
                SceneManager.LoadScene(sceneName);
            }
        }
    }
}

As a point of caution the script retrieves scenes other than the first in "Scene in Build". So you can create a scene for debug and attach the script.

Additionally, scene folder path should fix as "Scene".

How to merge two repositories with history?

KENTO⚽️XR Engineer😎 — Sun, 22 Jan 2023 08:16:43 +0000

Intro

I faced a situation that I would like to merge two repositories and keep to remain these histories.

I figured out it, so I write the way down on this article so I won't forget.

I will use Fork(Git client) but it is possible command line too.

Step1

First, I created two sample repositories and just kind of some commits.

A repository named "MergeTest1".

A repository named "MergeTest2".

Step2

This time, I will merge "MergeTest2" to "MergeTest1".

On the condition of what you have already had two repositories at local, a next step is add another repository as new remote repository.

And fetch all remote, checkout another repository.

Step3

A final step is merge.
A base is master(MergeTest1), so checkout master(MergeTest1) and try to merge master2(MergeTest2).

This time, I deliberately prepared conflict.

A below GIF is a resolving step.

If you avoid conflict, I recommned to evacuate your file at an other folder in advance.

【Unity】How to launch another exe placed at a relative path of the running exe.

KENTO⚽️XR Engineer😎 — Sat, 29 Oct 2022 03:44:43 +0000

Intro

I faced the situation that I would like to launch another exe placed at a relative path of the running exe.

So I write the way down on this article so I won't forget.

Sample Code

using System;
using System.Diagnostics;
using System.IO;
using UnityEngine;


public static class Launcher
{
    /// <summary>
    /// relative pass
    /// </summary>
    private static string path = "..\\..\\..\\target.exe";

    /// <summary>
    /// launch target exe and kill self
    /// </summary>
    public static void LaunchAndKillSelf()
    {
        //move current directory
        Directory.SetCurrentDirectory(AppDomain.CurrentDomain.BaseDirectory);

        //start process
        Process process = new Process();
        process.StartInfo.FileName = path;
        process.Start();

        //kill self
        Application.Quit();
    }
}

Working directory is changed if the running exe was launched by another exe.

The code below is a workaround for that.

Directory.SetCurrentDirectory(AppDomain.CurrentDomain.BaseDirectory);

【Unity】How to get the game objects get using FindObjectsOfType in the same order as the hierarchy.

KENTO⚽️XR Engineer😎 — Sat, 29 Oct 2022 03:44:26 +0000

The list get using FindObjectsOfType is not in hierarchy order.
So, if you are important to use order, you must reorder the list.

Sample Code

private void Awake()
{
    var monoComponentList = FindObjectsOfType<MonoComponent>().OrderBy(m=>m.transform.GetSiblingIndex()).ToList();
}

【Unity】Can you explain whether Awake or Start is called when a Gameobject is activated?

KENTO⚽️XR Engineer😎 — Tue, 11 Oct 2022 15:40:44 +0000

Four years have passed since I started to use Unity, but I have misunderstood about the title.

Basically, Awake and Start are UnityEvent Function called when a Gameobject is activated.

But, how about are the below situations?

A Gameobject is active, a component is disable.

In this case, only Awake is called.

A Gameobject is inactive, a component is enable.

In this case, nothing is called.

Switch a Gameobject in the order of active, inactive, and active.

In this case, Awake and Start are called only once.

If you want to call something when a Gameobject's active changes, you can use OnEnable which is UnityEvent Function.

【Unity】How to refer to a gameobject sets DontDestroyOnLoad and inactive?

KENTO⚽️XR Engineer😎 — Sat, 28 May 2022 09:26:20 +0000

Intro

Unity has any kind of ways to refer arbitrary gameobject.

For instance, SerializeFieled,GameObject.Find("name").

But, if you need to refer arbitrary gameobject that sets DontDestroyOnLoad and inactive, you can not use GameObject.Find("name").

Or, there is the situation to not be able to use SerializeFieled.

Sample Code

private GameObject _empty;

void Start()
{
    //Create gameobject as DontDestroyOnLoadGameObject
    if (_empty == null)
    {
        _empty = new GameObject(string.Empty);
        DontDestroyOnLoad(_empty);
    }

    var dontDestroyOnLoadGameObjectList = new List<GameObject>();

    //Besause DontDestroyOnLoad is included Scene, it gets from GameObject.scene.
    var dontDestroyOnLoadGameObjectRootList = _empty.scene.GetRootGameObjects().ToList();
    foreach (var root in dontDestroyOnLoadGameObjectRootList)
    {
        dontDestroyOnLoadGameObjectList.AddRange(GetAll(root));
    }

    dontDestroyOnLoadGameObjectList.Any(go => go.TryGetComponent(out MyComponent component));

    //Some kind of processing
}


/// <summary>
/// Return all object of tree.
/// </summary>
private List<GameObject> GetAll(GameObject root)
{
    var allChildren = new List<GameObject>();
    GetChildren(root, ref allChildren);
    return allChildren;
}

/// <summary>
/// Add child to list from parent.
/// </summary>
private void GetChildren(GameObject obj, ref List<GameObject> allChildren)
{
    var children = obj.GetComponentInChildren<Transform>();
    if (children.childCount == 0)
    {
        return;
    }

    foreach (Transform ob in children)
    {
        allChildren.Add(ob.gameObject);
        GetChildren(ob.gameObject, ref allChildren);
    }
}

private void OnDisable()
{
    DestroyImmediate(_empty);
}

Tips

Because DontDestroyOnLoad is included Scene, it gets from GameObject.scene.

At first, create temporary gameobject and set DontDestroyOnLoad.
Second,search all of gameobject that has specific Component.
You can search in the scene that exist temporary gameobject.

It means to be able to search a gameobject in DontDestroyOnLoad.

【Unity】 A solution if you can't receive the event that finishes an app on mobile.

KENTO⚽️XR Engineer😎 — Fri, 07 Jan 2022 12:15:26 +0000

Intro

I tried to receive the app's end event on mobile.
However, it did not succeed.

So I have considered a compromise. I'll write it down.

Environments

name	version
Unity	2019.4.23f1

Problem

Unity has a solution to receive the app's end event.
It is OnApplicationQuit.

But it doesn't work on mobile.
OnApplicationQuit will only be called in situations that you explicitly call Application.Quit.

You can use OnApplicationFocus,but It is also called when working in the background.

Solution

I have come up with one solution.

First, I tried to figure out why I would want to receive the app's end event.

In my case, I wanted to delete the cache of streaming files.
Therefore, I changed the implementation to delete a files when I start an app.

//Call on start an app. 
void Start()
{
    try
    {
        if (Directory.Exists(Path))
        {
            Directory.Delete(Path, true);
        }
        Debug.Log("Cache delete");
    }
    catch
    {
        Debug.LogError("Error deleting files.");
    }
}

It is my compromise solution.

If you want to send game scores and statuses at the end of the app, you may want to save the data when the user takes some action and send it at startup.

【Unity】How to use Git LFS.

KENTO⚽️XR Engineer😎 — Sat, 27 Nov 2021 16:31:19 +0000

Intro

If your a file is larger than 100MB, you will need to manage it with Git LFS.

I write the way down on this article about how to use Git LFS.
Since I have many opportunities to use Unity, I will write based this on a simple Unity sample.

Environments

name	version
Unity	2020.3.4f1
Fork	1.69.3.0

What is Git LFS?

Git is a distributed version control system, meaning the entire history of the repository is transferred to the client during the cloning process. For projects containing large files, particularly large files that are modified regularly, this initial clone can take a huge amount of time, as every version of every file has to be downloaded by the client. Git LFS (Large File Storage) is a Git extension developed by Atlassian, GitHub, and a few other open source contributors, that reduces the impact of large files in your repository by downloading the relevant versions of them lazily. Specifically, large files are downloaded during the checkout process rather than during cloning or fetching.

【reference source】：Git LFS

In a nutshell, it makes it easier and more convenient to work with large files on git.

And we can not manage a large file without Git LFS.
【reference source】：About large files on GitHub

Experiment without Git LFS

We tested using Fork, a client tool for using git, to push a file larger than 100MB.

It failed as expected.

How to use

I use Git for Windows, which includes Git LFS, so I'll skip the installation steps.

First, copy the path to the large file.

Next, open the console and enter the following command.

$ git lfs track [path]

If successful, ".gitattributes" will be added and the lfs message will be written.

If you have already created commit that contains a large file, you have to enter the following command.

$ git rm --cached [path]

【Unity】How to convert DoTween to UniTask and wait to complete all sequences.

KENTO⚽️XR Engineer😎 — Sun, 26 Sep 2021 06:18:58 +0000

Intro

I thought that I wanted to treat as UniTask and wait for all of sequences when I use DoTween.

I write the way down on this article so I won't forget.

Environments

name	version
Unity	2020.3.4f1
DOTween (HOTween v2)	1.2.632
UniTask	2.2.5

Setting up

First we’ll import DoTween and UniTask to our unity project.

Next set UNITASK_DOTWEEN_SUPPORT on Scripting Define Symbols and select Apply.

But under my environment it wasn't applied to change settings for unknown reasons.

So I opened whatever assembly definition assets in the project, modified them once, and revert them.

In my case, it worked that way.

Sample Code

using System.Collections.Generic;
using System.Threading;
using Cysharp.Threading.Tasks;
using DG.Tweening;
using UnityEngine;
using UnityEngine.UI;

/// <summary>
/// Sample of DoTween which treats as UniTask and wait to finish the task. 
/// </summary>
public class WaitDoTweenTaskSample : MonoBehaviour
{
    /// <summary>
    /// For task text
    /// </summary>
    [SerializeField] private Text[] _taskTexts;

    /// <summary>
    /// For completion text
    /// </summary>
    [SerializeField] private Text _completeTaskText;

    async void Start()
    {
        //Wait to complete task gave to argument.
        await UniTask.WhenAll(FadeTasks(this.GetCancellationTokenOnDestroy()));
        //When completed, fade in the text.
        _completeTaskText.DOFade(1.0f, 2.0f).Play();
    }

    /// <summary>
    /// Return task list that converted the fade sequences.
    /// </summary>
    /// <param name="ct">CancelToken </param>
    /// <returns>Task list</returns>
    private List<UniTask> FadeTasks(CancellationToken ct)
    {
        var taskList = new List<UniTask>();

        foreach (var taskText in _taskTexts)
        {
            var randomValue = Random.Range(1.0f, 5.0f); 
            taskList.Add(  taskText.DOFade(1.0f, randomValue).Play().ToUniTask(cancellationToken: ct));
        }

        return taskList;
    }
}

Demo

After all of fade sequences completed, a completion text starts to fade in.
