For enviorments, there a a 3D model except much larger an interactive?
So if they are then Could I create lik a city in blender an export it into .egg and use it in my game?
You can certainly create a large environment in Blender and export it to .egg to use in your game. If you want to make the environment interactive, that’s what you do in Python code.

The hint is to use meaningfull names for your meshes inside your environnment. This was you can access them by code. There is a “find” cmd to do so. Also a trick can be to have a rule for your meshes like Category_Name. This way you can loock for a specific mesh or all meshes from one category.
