Is there an easy way to script 48 different text buttons into one call function in a script?

There actually is a pretty simple way of doing this with a loop. If they all have the same parent, then you could easily just do it this way:

Children=script.Parent:GetChildren()

for _,Child in pairs(Children) do --Goes through and assigns the function to all of them.
    if Child:IsA("TextButton") then
        Child.MouseButton1Click:connect(function()
            --Code here for function
        end)
    end
end

Anyways, this would be the simplest way of doing it. Another way however if they don't have the same parent would be to do this:

Children={} --Make a table of ALL of the Textbuttons here

for _,Child in pairs(Children) do --Pretty much the same from here
    if Child:IsA("TextButton") then
        Child.MouseButton1Click:connect(function()
            --Code here for function
        end)
    end
end

Anyways, I hope this helped you out a bit. If you have any further problems/questions, please leave a comment below, and I'll see what I can do :P
