here in this script, I want to do like if the first slot it’s occupied it’ll go on to the next one. if all are occupied then it’ll print/warn smth.

You just need a function to loop over each possible slot and return the first one that’s available. If the function reaches the end it should warn. It could look something like this, but I don’t know how you’ve decided to identify occupied slots:

function nextTower()
	for slotIndex, towerSlot in pairs(towerSlots) do
		if towerSlot.Occupied == false then
			return slotIndex
		end
	end

	warn("No available tower slots")
	return nil
end

What do you mean? What did you write?

#5

No, i mean how does it work. I mean do I parent the world model to the index? edit: alr I am dumb, so I not to the proper index, anyway I have figured out:d
