Connect group function to individual object?
I have a GUI with buttons and a function that fires whenever any of the buttons are clicked. However, the function doesn't seem to be returning any data about the actual particular button that was clicked. Is there a way to make this work?
local frame = script.Parent
--script errors at the print function because button never actually exists
function buttonClicked(button)
print(button.Name .. " was clicked!")
end
for i,v in pairs(frame:GetChildren()) do
-- Let's go ahead and check if the object is a button in the first place
if v:IsA("TextButton") or v:IsA("ImageButton") then
-- Connect the event to that individual button.
v.MouseButton1Click:connect(buttonClicked)
end
end

Callbacks
What you're referring to is a callback. This is basically a way to have a function call another function, while passing arguments to the function it's calling. This is extremely useful in a lot of specific cases. Here would be an example in your scenario:
local frame = script.Parent
--script errors at the print function because button never actually exists
function buttonClicked(button)
print(button.Name .. " was clicked!")
end
for i,v in pairs(frame:GetChildren()) do
-- Let's go ahead and check if the object is a button in the first place
if v:IsA("TextButton") or v:IsA("ImageButton") then
-- This makes it so once the button is clicked, it will call
-- 'buttonClicked', while also passing the argument 'v'
-- to it, which is the button.
v.MouseButton1Click:connect(function()
buttonClicked(v)
end)
end
end
Hope this helped, let me know if you have any questions.
