Thank you. I have few questions:
*Will this make movement smooth? Cause if I got you right, the method you showed me, will just place player at the new level, with distance from door from old level's door. Am I right?

* how to make this without loading new level, cause I'll make all levels(rooms) in one big level.
I need to be able to move smoothly between door, as I said before. I need to be able even to stop right between doorways.
