hello guys, i’m very new in unity (or programming in general)
so i have a question, i try to make unlimited running game
quite generic genre and such, the way i design it is, i will make a parent with bunch of road layout as its child ( which all inactive except 1 for start), and then i move the parent toward the player and it’ll go on and on, and will activate and reposition it’s child accordingly
now my question is, as the parent move, it’ll take space in the non-viewable canvas/display on the game world, and it’ll be go until god knows when, is doing it like that a good practice?, will it take and stress up the memory as it goes further?
i have no idea how unity work, and i already try to google stuff regarding this but found nothing
please hand me a rope 
, thank you in advance
