for i,v in pairs(table) do
  corountine.wrap(function()
      -- code
  end)()
end

this? it will ignore the wait() and all and continue the loop, basically performs the code but doesn’t wait for it to end to perform the next one. I don’t know what do you mean by randomly and doesn’t repeat itself.

#5

Can you send us your script? I don’t really get what you mean. For loops don’t repeat anyway

Do you mean

local tbl = {}
for i = math.random(),math.random() do
if not table.find(tbl, i) then
table.insert(tbl, i) 
print("Random index is:"..i) 
end
end
#7

yes smthg similar to tht but i shouldnt repeat itself

#8

And for what purpose do you need it?
Chance system?

Then just use math.random(), if you’re only running it once then there’s no need for a for loop.

For example,

local randomNumber = math.random(1,10)

if randomNumber = 6 then
    --do something
end

sort of its like for randomly going thru a list of floors like not 1 by 1 just randomly

#11

well there is need for a for loop since i have to go thru all floors but just not in order

#12

Oh okay. You’d need to make a table for this. Use :GetChildren() on the directory in which your floors are stored and add each individual floor to a table. Then randomize the table.


local FloorFolder = game.ReplicatedStorage.FloorFolder:GetChildren()
local table = {}

for i = 1,#FloorFolder do
    table.insert(table,1,i.Name)
end

--This should give you a table with each floor in it.

--You should now shuffle the table
