Is it possible to do something untill something dose not exist?

Asked Feb 10, 2021230 views2 answers

So im trying to make a stand system where you picks a random stand but I dont want it to pick a stand with a value named "Private" in it. I just dont know a efficant way to keep picking a random one untill it finds one without the tag. This is the script that picks it:

local Stand = game:GetService("ServerStorage").Stands

local items = Stand:GetChildren()

local randomStand = items[math.random(1, #items)]
if randomStand:FindFirstChild("Private") == nil then
	return
else
	local randomStand = items[math.random(1, #items)]
end

Thanks in advanced

You need to filter out private stands with public ones and then select random one from the public ones, using ipairs loop it should not be a problem

local Stand = game:GetService("ServerStorage").Stands

local items = Stand:GetChildren()

local public = {}

for _, Item in ipairs(items)
do
	if not (Item:FindFirstChild("Private"))
	then
		table.insert(public, Item)
	end
end

local randomStand = public[math.random(1, #public])

I hope you get the idea. Read about loops here if you don't understand them.

If you want to repeat something until stand is not picked, you can simply repeat a function if the stand is not private, can look like this

local function FindStand()

	local randomStand = items[math.random(1, #items])

	if (randomStand:FindFirstChild("Private"))
	then
		FindStand()
	else
		print('Found')
	end
end

FindStand()

If the stand is private, it will call FindStand again which will do the same thing but will select other stand.

What is the varible for the awser of the FindStand() (The selected stand)

In the FindStand function on line 9 you can replace print('Found') with return randomStand, that will return the stand that has been randomly picked. Or this is not what you mean?

    return

    local randomStand = items[math.random(1, #items)]

local randomStand = items[math.random(1, #items)]
if randomStand:FindFirstChil("Private") == nil then
