How do I cycle through a Table?
I've got a teleport script with several destinations. How would I cycle through the table when I press a button to get to the next selection?
Ex.
local Destinations = {
["House"] = Vector3.new(10,20,10);
["Street"] = Vector3.new(10,10,40);
["Office Building"] = Vector3.new(190,5,440);
}

You should research "for i,v in pairs" iGlaciem 72 — 7y

Generally you would want to use numerical indices for something like this, but in order to do it with what you have, you could create a new table with the indices of the first, and use that to cycle through it:
local Destinations = {
["House"] = Vector3.new(10,20,10);
["Street"] = Vector3.new(10,10,40);
["Office Building"] = Vector3.new(190,5,440);
}
local indices = {};
local current = 0;
for i in next, Destinations do
indices[#indices + 1] = i;
end;
local function cycle()
current = (current < #indices) and current + 1 or 1;
return Destinations[indices[current]];
end;

Hope this helped.
