Script for the four parts sliding door

[ainst Composer]

Hello! I need to create a script for the four parts door sliding. the door must be linked to the building.

Each part do not enter one into the other, but come in behind one after another.

Parts can simply move from one position of all parts to another.

Any suggestions greatly appreciated!

Please, help! reward 500 ls.
