Unity/課金/サンプル

提供: 初心者エンジニアの簡易メモ
移動: 案内検索

都度購入

Androidの場合

  1. GooglePlayDeveloper/指定アプリ/ストアで表示/アプリ内サービス/管理対象のアイテム/管理対象のアイテム作成
  2. プロダクトidを(stone10)などで入れる(storeと連携してないと、購入ボタンを押しても商品が無いとなる)
  3. 有効にするを選択して、有効になっていることを確認

日本語を追加した場合は、日本語の説明も入れないと、保存されないので気を付ける。

iOSの場合

  1. ituneconnect管理画面/app内課金/管理/+をクリック
  2. 消耗型を選択し、id(stone10)などを入れてく
  3. 審査用の画像は(640 x 920)で登録すればよい
  4. ituneconnectから契約を選択して、有料Appの利用規約に同意
  5. 口座情報を入れる(ゆうちょなら"Japan Post Bank"で"9900-[口座番号]"
  6. 納税にアメリカ納税情報を入れる
  7. 納税情報を入れたところOnInitializeFailed(NoProductsAvailable)の失敗イベントが呼ばれなくなり、正常にOnInitializedが呼ばれるようになった^^
"Type of Income"は"Income from the sale of applications"
Capacity in which acting欄に "Self"

定額課金

Androidの場合

  1. GooglePlayDeveloper/指定アプリ/ストアで表示/アプリ内サービス/定期購入
  2. プロダクトidを(com.example.hogeapp.monthly)などで入れる(storeと連携してないと、購入ボタンを押しても商品が無いとなる)
  3. 有効にするを選択して、有効になっていることを確認

日本語を追加した場合は、日本語の説明も入れないと、保存されないので気を付ける。

iOSの場合

  1. ituneconnect管理画面/app内課金/管理/+をクリック
  2. 自動更新サブスクリプションを追加(自動更新サブスクリプションがない場合は、ユーザ権限のとこの有料Appの契約とアメリカ納税情報が入ってるか確認する)
  3. プロダクトidを(com.example.hogeapp.monthly)などに
  4. 期間を1ヶ月とかに設定する

Unityから課金用ボタン設定

課金の記述方法として以下2パターンがある

  • 全部コードで処理する方法
  • コードレス処理がある。

全部コードで処理する場合

  1. 以下課金呼び出しコードを記述(例:stone10はproductID)
UnityIAPManager manager;
manager = new UnityIAPManager();
manager.OnPurchaseClicked("stone10");

UnityIAPManager.cs

こちらを使ってもいける。

https://gist.github.com/YoshihideSogawa/f7c118127ce50e593a5b4a12e8426d6e

  1. 上記をPurchaser.csで保存する
  2. Unityのヒエラルキーに新規Objectを作成し、適当な名前で、Purchaser.csをアタッチする

コードレスの場合

(未完成です)

  1. unityメニュー/windows/UnityIAP/CreateIAPButtonでボタンを作成する
  2. unityメニュー/windows/IAP Catalogをクリックし以下のような詳細データを入れる
id:monthlyなど
type:Subscription(自動課金)
  1. 作ったbuttonのプロパティのproductIdに先ほどいれたid(monthlyなど)いれる
  2. Assets/Plugins/UnityPurchasing/script/CodelessIAPStoreListener.csにイベントが発生するので確認する

公式デモ

課金プラグインを入れると、以下に入ってるので確認する

  • Assets/Plugins/UnityPurchasing/scenes/IAP Demo.unity
  • Assets/Plugins/UnityPurchasing/script/IAPDemo.cs
