As an experienced game development engineer with a keen understanding of Unity and C# languages, I am more than capable of delivering the specific experience you're after. I've dedicated my career to mastering Unity 3D, scene management, and script design to create seamless experiences just like what you describe needing for your banner ads.
My confidence comes from not only being proficient in C#, but also understanding nuanced concepts like scene batching and minimizing reloads. I know how important it is to keep banner ads throughout the game while balancing them with overall user experience. Adherence to AdMob policy is often understated but critical, especially when it comes to continuous reloading of ads during rapid scene transitions. With my skills, this will never be a concern.
Overall, I bring a collective skill set centered around game development that fits seamlessly into your project requisites. The unique juxtaposition of my broad understanding of Unity technology and the specific skillset like integrating ad platform like AdMob makes me the ideal candidate for your Unity game project. Together, we can make sure that your banner ad stays active across all scenes without any violations or disruptions.
