# トラッカーアプリ構築ガイド

## 概要

PortalgraphアプリケーションはOSC通信でトラッカーアプリから座標を受け取り、それに合わせた映像を表示します。受信プロトコルは[VirtualMotionTrackerのAPI](https://gpsnmeajp.github.io/VirtualMotionTrackerDocument/api/)の部分集合になっています。\
受信ポートは標準で49570番になります。

## API一覧

PortalgraphのOSC通信は以下のAPIをサポートします。

**/VMT/Room/Unity (int)index, (int)enable, (float)timeoffset, (float)x, (float)y, (float)z, (float)qx, (float)qy, (float)qz, (float)qw**\
Unity lik Left-handed space, Quaternion, and Room space. (Recommended)\
Unityと同じ左手系かつ、クォータニオンかつ、ルーム空間(推奨)

**/VMT/Room/UEuler (int)index, (int)enable, (float)timeoffset, (float)x, (float)y, (float)z, (float)rx, (float)ry, (float)rz**\
Unity lik Left-handed space, Euler angles, and Room space.\
Unityと同じ左手系かつ、オイラー角かつ、ルーム空間(推奨)

**/VMT/Input/Button (int)index, (int)buttonIndex, (float)timeoffset, (int)value**\
Button input. ボタン入力\
value(int):1=press, 0=Release

**/VMT/Input/Button/Touch (int)index, (int)buttonIndex, (float)timeoffset, (int)value**\

**/VMT/Input/Joystick/Touch (int)index, (int)joystickIndex, (float)timeoffset, (int)value**\
Joystick touch input. ジョイスティックタッチ入力\
value(int):1=press, 0=Release

**/VMT/Input/Joystick/Click (int)index, (int)joystickIndex, (float)timeoffset, (int)value**\
Joystick click input. ジョイスティッククリック入力\
value(int):1=press, 0=Release<br>

## アプリの登録

作成されたトラッカーアプリは、Portalgraphから自動起動可能です。

F12キーを押して開かれる設定画面左下のトラッカーアプリにアプリのパスを入力すれば、起動時に自動で起動します。

また、\
（WindowsのDocumentsフォルダ）/Portalgraph/portalgraph\_user\_trackers.json\
にアプリを以下のように記述することで左下のドロップダウンにアプリを追加することが可能です。

```
{
  "trackerApps":[
    {
      "name":"Great Tracker",
      "path":"C:/YourGreatTracker.exe"
    }
  ]
}

```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://portalgraphvr.gitbook.io/portalgraphdokyumento/kedokyumento/tracker-app-guide.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
