Unity游戏项目接广告

Unity游戏项目中接入GoogleAdMob

先看效果图

接入测试横幅广告，代码如下：

}

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
