How do I use 'local'?

Asked by

I want to shorten my script by making one of those things: local buttons = script.Parent.Parent.Button1 I also want to be able to use buttons for Button2 and Button3. How do I have multiple things under one local thingy?

Thanks, - Sam4550

You're looking for tables. You can put

local buttons={script.Parent.Parent.Button1,script.Parent.Parent.Button2,script.Parent.Parent.Button3}

and then, later on use

buttons[1]
buttons[2]
buttons[3]

Of course, there are better way to do this. To shorten your code more, you can do

local container=script.Parent.Parent
local buttons={container.Button1,container.Button2,container.Button3}

Or

local buttons={}
for i=1,3 do
    buttons[i]=script.Parent.Parent["Button"..i]
end

Or, if the buttons are the only thing in the container,

local buttons=script.Parent.Parent:GetChildren()

Then, later on, instead of repeating code 3 times, you can do

for number,button in pairs(buttons) do
    button.Text="Example"
end

If you're having trouble understanding that last bit, you can read about the generic for loop.

Thanks, it seems to make sense. I'll just try using it first. Sam4550 42 — 10y
