事前ロード

CreateAndLoadRewardedAd()をHandleRewardedAdClosedで実行すれば良い。

CreateAndLoadRewardedAd()内にrewardedAdをifでnull判定すると事前ロードができないので注意

広告取得完了時に画面遷移するとアプリが落ちる対処法

iosなら以下のようなエラーがでる時

libc++abi.dylib: terminating with uncaught exception of type Il2CppExceptionWrapper

TitleScript.csがTitleSceneのシーンにアタッチしてる時の場合の例

public void HandleRewardedAdLoaded(object sender, EventArgs args)
{
    MonoBehaviour.print("HandleRewardedAdLoaded event received");
    // csの名前じゃなくてアタッチしてるSceneの名前を入れる
    if (Application.loadedLevelName.Equals("TitleScene")) {
        if (rewardButton != null)
        {
            rewardButton.transform.position = new Vector3(2.32f, 2.40f, rewardButton.transform.position.z);
        }
    }
}

エラー対応

以下エラーが出るとき

error CS0246: The type or namespace name 'EventArgs' could not be found (are you missing a using directive or an assembly reference?)

以下を追加する

using System;
