How do you loop through a table but each time it loops it's looped in a different order?
I'm working on a project where there are these lines of code that scroll through each player in game.Players, but in a certain order. Is there a way for that order to be random?
[EDIT] I hope this isn't too vague, but here's a simple script I made about the problem.
while true do
for i,v in pairs (game.Workspace.Folder) do
print(v.Name)
-- I don't want it to go through the whole folder, but I want it to go through it in a random order.
end
end

You could make a table of random indexes, and check if the index exists, to know to add it or not. Then, repeat that until the table has the correct length, and loop through. Example implementation:
function rpairs(Table)
local function Contains(Table, Item)
for i,v in ipairs(Table) do
if v == Item then return true end
end
return false
end
local Result = {}
local Indexes = {}
repeat
local Index = math.random(1, #Table)
if not Contains(Indexes, Index) then
table.insert(Indexes, Index)
end
until #Indexes == #Table
for _, i in ipairs(Indexes) do
table.insert(Result, Table[i])
end
return ipairs(Result)
end
-- iterate through table:
for i,v in rpairs(game.Workspace.Folder:GetChildren()) do
print(v)
end
