Yes, thanks, but would you please at least give me some resources or sites or even tell me coding using what?

Maybe my question is not clear, sorry for that, but what I meant is that I want to put stores shaped like mall or houses or anything like that, on a frame that I can navigate through, not a google map. Like "hay day" game if you know it.
Your help is kindly requested and appreciated.

Hello!

I have started the tutorials, where I can find a map with buildings?

I want to add buildings to a mobile app and when I click on them a list of items with their prices are displayed. Like warehouse. Example :
1- login ( create building)
2- add items
3- navigate through the map that contains the buildings.

Any help please, and thanks.
