How to make the effect of entering the elevator in 2D?

Question

Unity

For example, if you have a 2D elevator and player asset

, you want the "back" part to be behind the player and the "front" part to be in front.
What are the options (preferably using Unity)?

Answer 1

2D is also 3D. Just drag the back to the bottom layer, the front to the top layer, and the character in between.
