Is this way of multilevel possible?

Hey people, I've been trying to google this for days now but I can't find an appropriate solution, so I wonder if it's just this blatantly easy that nobody ever asked or too rare that those who can do it just quietly did it.

Basically, I am using 3/4 topdown perspective and want to have multiple floor accessible for the player, but depending on their position, the view changes - I drew an image to illustrate, apologies for any inaccuracies, it's just a sketch:

To the left is the ground floor of the building, to the right, the whole building including the upper floor. The players are numbered. I want players to be able to change floors by for example stairs or like in my picture a ladder, however, if there is for example a hole at the second floor (as in this case leading down to the ladder), it should be visible, and should there be a character near, it should also be drawn. If a player is standing close enough to the building, they see inside of it such as player 1 in the left version, if they are further away such as player 1 in the right one, they see the whole building.

In the right building, player 3 can see both player 1 (through the window) and player 2 (as there is a hole in his floor). Player 2 cannot see player 3 because he sees his own floor (left building) and a hole "up" wouldn't and shouldn't work in what I'd like. Player 1 on the right building can see player 3 if 3 is close enough to the window and 1 is far enough away to see the whole building instead of his floor only, as in the left image.

I hope I could point out what I'd like to do, I think I remember something similar like this but in a different perspective in a game from way over 10 years ago. Since I am a novice with Godot: Is this even possible or does it take great expertise and effort? I'm unsure as of where to start, and as I've said in the introduction, google has barely any results for Godot 2D multilevel stuff. If anyone has an idea how to approximate this even with drawbacks or not everything working this way but similar, feel free to be heard! Thanks for listening folks, have a good day.

I believe a game that does this is Tibia

I'm not sure what the solution of this is, but maybe the screenshot from a game can help others understand the concept you'd like to get.

Thanks man, that's indeed the game I was remembering! The only difference is that they skew their sprites by 45°, whereas I would just use 3/4 topdown, but I guess in terms of concept, it shouldn't matter. Do you think this requires a hard coded solution and I am wrong in posting this in the 2D section?

Here are the screenshots from the game for anyone interested: https://www.tibia.com/abouttibia/?subtopic=screenshots

I merged some of them to give an idea how it works.

First (top-left) shows how it looks when inside of a building (or directly in front of a door/window), you can see inside and only see the floor you are on. 4th (bottom-right) also shows only the floor you are on because you are inside, but in this case, on the 2nd floor. In both cases, you can still see what's happening around you and, should there be any, floors below. I keep trying around to get it to work somehow but to be honest I'm just too bad.

Edit: It actually seems like my initial image was wrong, and at the right building, player 1 would still see the his own floor and not the full building, as he is standing in front (even if not directly) a door. Would they stand 1 square either to the left left or right, it would be correct again.

Have a separate tileset for each floor/level and a property keeping track of what floor level the player is supposed to be on. Each time the player moves through some portal/such as a literal teleportation portal or stairs or ramp or door or what ever) the players floor value would get changed.

Based on the value you then have a function that enables/disables visibility of the relevant tilemaps.

Thanks, will try this and report back later!

@Trevor5482 Just checking in! I love the game above, and while i don't play it I like to check in and see their updates here and there... so the fact that you're trying a similar thing that they do is exciting!

I remember when there were player killers (PKs) and you were in a higher place and you could see them below, it was unnerving. A good times in the early days.

Same strategy for Pks... they could see someone approaching from a higher level and the lower level player were non-the-wiser xD
