cocos2d/cocos2d-x ? reverse-engineered prompt

I want to build a foundation for creating 2D games using C++. I've heard of an open-source engine called Cocos2d-x and would like to use that as the base. The main goal is to create a framework that can run on multiple platforms, like iOS, Android, Windows, and macOS, without having to write separate code for each.

I'm not a pro-gamer, I'm thinking of simple games, interactive demos, or maybe even an interactive book. Please set up a project that includes scene management for switching between different screens, sprite animations for characters, and basic UI like menus and buttons. It absolutely needs to have a physics engine integrated for handling things like gravity and collisions. Also, include support for tilemaps so I can design levels easily. Just get the basic engine project set up and ready to go.
