First question:
How can I use Physical Behavior 2.0 in a top-down game?
Second question:
This is probably not possible. Is there any way to use your smartphone as a controller on android and windows without third-party software. It must be programmable in gdevelop or at least implementable in a project and it must be simple for all players. Similar to Air Console.
Thanks to the community and sorry for translation errors, I don’t speak English.
