カメラブロック

カメラブロックは、APIを提供しているWi-Fi 対応カメラをMESHからコントロールするためのソフトウェアブロックです。
今回の例では、シンプルに写真を撮影する、"TakePicture" Functionを備えたブロックを実装します。

ここでは、RICOH THETA Web APIを利用して、株式会社リコー製「THETA SC」をコントロールします。
ブロックを利用するには、カメラとMESHアプリの動作端末を同一ネットワークに接続してください。

 

カメラブロック : コード

"TakePicture" Function

"TakePicture" Functionのソースコードは以下の通りです。

	runtimeValues : { sessionId: "" }

カメラブロック : Import用 JSONデータ

以下にImport用のJSONデータを記載します。「Import機能」を参考にJSONデータをImportすることで、SDK上でブロックの作成、設定項目、コードの確認、編集が可能です。
