How do i make a math.random() go through a table until it finds an option that isn't taken?
So for my game kind of like lt2, i need to cycle through a table of tree models. inside those models i have a bool value set to false by default. I got the table by doing game.ReplicatedStorage.OakTrees:GetChildren() and I want to do a math.random() to go through it but if i check if the value is false, how do i make it do math.random again? because if it does that and its still false, it could keep the process going and i dont want to have like 1 million else statements. Thanks for the help!

Also, you cant do a while true do local random = math.random(1,#game.ReplicatedStorage.OakTrees:GetChildren()) if random.Taken.Value == false then --code end end SkiH1gh 14 — 3y

Sounds like you need to use a repeat ... until loop. Which would fit into your case like this:
local trees = workspace.Trees:GetChildren()
local option
repeat
option = trees[math.random(1, #trees)]
until
option.BoolValue.Value == true
If I were you, I'd use a for i,v in pairs loop instead:
function getFirstTree()
for index, value in pairs(trees:GetChildren()) do
if value.BoolValue.Value == true then
return value
end
end
end
local option = getFirstTree()
