场景1，MainCamera上挂载上面两个脚本，GoogleAdMobManager .cs和 GameMgr.cs
创建StartButton按钮
场景2，加载插屏广告InterstitialAd，Main Camera上挂载Game Mgr.cs
创建Pause Game按钮，当暂停的时候，显示插屏广告，调用Game Mgr.cs中OnPauseButtonClick()方法
创建Jump to reward ad,点击跳转到激励广告。点击JumpButton触发GameMgr中JumpButtonClick()方法。
场景2，02-play中的Main Camera上的Audio Listener需去除，项目场景中只能有一个Audio Listener
场景3，加载激励广告
