So, for a building game, I want it to save what ever one has built when they leave or lose connection. However, as far as I know, data stores only save values and the wiki says that I cannot save parts in Data Store.
Still, is there any possible way to make the parts go under data store?
If no, then what else can I do?
Answer: Nope
You cannot. The best way to do it is to use tables, still, it isn't easy, also make sure that the player can only build on a certain area and it unloads when he leaves because it can be weird if you don't.
You would save what the parts represent.
Say you have a "wall" You would save in your table
myTable[part1] = "wall"
It's up to you as the programmer to read from that table and create the part. You'll also save things like how big the wall is, what color the wall is and so on.
