You might not get this but I’ll explain it:
I have two baseparts I want to respawn at the same time, but they must have the same time to respawn.
One basepart spawns at the beginning and another spawns a couple seconds after [7 seconds] and I need to make them respawn at the same time.
How do I do this?
your question doesn’t really make sense. can we see the script and then explain in detail exactly what you want?
Sorry in advance if i misunderstood.
But i believe you can just do a while task.wait() loop and keep checkong if basepart1 is in the workspace (respawned) if so, parent basepart2 to the workspace.
If i misunderstood or you need more help, let me know 
Yeah, I can get if it’s confusing..
Each part has a respawn loop attached to it.
Basically, if base part 2 spawns in late, it’s not going to respawn at the same time as base part 1.
How could I fix it?
If a BasePart is spawned in late, how is it gonna respawn if it never gets destroyed? What do you mean by “respawn”
Ok, just to visualize it, I’m just going to make it into a video.
(note: this is a representation of the two base parts. i don’t really have a script for it yet 
)
Aha, thanks for the video! Why not just check every 5 seconds (or the delay before the respawn) to see if a part should respawn or not (in this case checking if the top part has been destroyed yet), and if one of them meets the condition then respawn it.
Well the issue is that I’m going to be having multiple different parts with respawn times.
Two with 3.. One with 4.. 8 with 5.. etc.
It all needs to be synced somehow, so number 4 respawns EXACTLY 1 second after 3.
Sorry for the late response. Maybe you could have a table that maps between the object and its respawn time. That way it would be easy to change an objects respawn time/add a new object.
