Android でのリワード広告の実装

広告を視聴したユーザーに報酬を与えると, ユーザーエンゲージメントが向上し, 収益の増加につながります。例えば, ユーザーに与える報酬には, ゲーム内通貨, 消耗品, 追加のライフ, 経験値の倍増などがあります。リワード広告を効果的にデザインする方法の詳細については, 収益化戦略 ガイドを参照してください。

動画広告を最後まで視聴したユーザーに報酬を与えるには, IUnityAdsShowListener.onUnityAdsShowComplete リスナーコールバックメソッドの UnityAdsShowCompletionState の結果を使用して, ユーザーが広告の視聴を完了し, 報酬を受け取る資格を得ているかどうかを確認します。

動画リワード広告ボタン

動画リワード広告ボタン

動画リワード広告では, プレイヤーが広告の視聴を選択できるボタンを実装するのが一般的です。リワード広告ボタンを作成するには, 以下のコード例を使用します。この広告ボタンを押すと, 広告が初めてロードされたときに限り, 広告が表示されます。ボタンの設定については, ボタン に関する Android 開発者向けドキュメントを参照してください。

ボタンを実装したら, 以下のコードを使用してスクリプトを追加します。showAdButton はビューで設定されたボタンを示します。
