Math.random for objects?
I'm trying to pick a random ImageButton from my gui. I get a bad argument because random is expecting a number and not an Object.
this = script.Parent
local btn = this.Buttons:GetChildren()
for i = 1,#btn do
b = math.random(1,btn[i])
print(b)
end
end

You don't need that extra 'btn' in there!
Instead of doing b = math.random(1,btn[i])
Try doing b = math.random(1,i)
and then to get the random gui part just do
local randomButton = btn[b]

To pick a random ImageButton from your GUI.
UNDERSTANDING YOUR ERROR
"math.random is expecting a number and not an object."
The math.random function accepts at most two arguments, and they both must be integers.
You must be aware that this is a table:
local btn = this.Buttons:GetChildren()
Because the :GetChildren() method fetches every child in your this.Buttons and puts it in a table.
b = math.random(1, btn[i])
So what you're doing is you're indexing/accessing the table, so you get an object instead - which is the child of this.Buttons, but what you probably intended to pass an integer.
local this = script.Parent local btn = this.Buttons:GetChildren() local RandomInteger = math.random(#btn) -- The minimum argument is assumed to be 1. -- RandomInteger is a number. local RandomButton = btn[RandomInteger] -- Index the table with your RandomInteger (the random number).
You don't need a "for" loop, else you will iterate through ALL of the buttons when you only need 1.
Read up on arrays if you don't understand line 6.
