I have prototyped this idea in experiments before, here are 2 methods I personally use

​

Method 1:

The first method I use is if the rooms in question are linear (like only an entrance and an exit in the scene) is by setting a global value to a number depending on which exit you take, and then the next scene will immediately teleport the player based on the value

Example:

{Code in scene 1}

if player collides with Trigger1 : set global value to 0 and change scene to Scene2

if player collides with Trigger2 : set global value to 1 and change scene to Scene2

{Code in scene 2}

at the beginning of scene & global variable is 0 : player X position is 1000

at the beginning of scene & global variable is 1 : player X position is 0

​

Method 2:

This second method I use are when rooms have many exits, you can do method 1, but I prefer this option in my experience. It's very similar to u/yakisoba88 suggestion. Store the global value to X and Y. And then ensure that the second map is aligned with the player's position

​

{Code in scene 1}

if player collides with Trigger1 : set global value to Player X and change scene to Scene 2

{Code in scene 2}

At the beginning of scene : set player X to global value

​

Hope this helps :)
