little beginner problems

Hello everybody. I faced a small problem that could not be solved. Or I just don’t see it. I need to open a new layer every time when I click the mouse (which is previously invisible) And it turns out to me that when you click the mouse, it opens everything at once. Although in the events I prescribe everything in turn. There are still questions about resizing the camera, I can’t do that either. While digging in the manuals. Thanks in advance for the answers) Sincerely yours to the community.

What do you mean open a new layer? You can only create a new layer in the editor (you refer to doing things in events, which makes it confusing).

If you are trying to show (unhide) a layer via events, then can you provide a screen shot of those events?

Or are you trying to Add a New Layer in the editoy?
