How to randomly assign a “bed” to multiple NPCs ?
How could I assign a random bed to multiple NPCs at the same time without them ending up using the same bed? Help is appreciated since I cannot finish the night cycle without this, therefore can't continue the game development.
Simple explanation: A player creates a town, new villagers (NPCs) want to live in the town. The player places multiple beds, and once It's nighttime villagers need to go to a random bed without ending up on the same bed. Similar way to Minecraft villagers
I've tried using math.random() on a table but they ended up on the same bed.
Thanks!!!!

Put the math.random() result into a list. If you find the same result inside the list when you generate a new math.random() value, keep choosing a new bed until you get a bed that is not occupied.
Example:
local List = {}
local Index1 = math.random(1, 3)
local Index2 -- Placeholder
local Index3 -- Placeholder
-- Put the Index1 result into the List
table.insert(List, Index1)
-- Repeat until Index2 have a unique number that doesn't exist on List
repeat
Index2 = math.random(1, 3)
until not table.find(List, Index2)
-- Put the Index2 result into the List
table.insert(List, Index2)
-- Repeat until Index3 have a unique number that doesn't exist on List
repeat
Index3 = math.random(1, 3)
until not table.find(List, Index3)
print(Index1, Index2, Index3) -- Run this code a few times, and you can see they are all randomized but never repeats
