    Array help

    edited February 2017 in General questions
    I'm new to Gideros and lua. I want to create an array of numbers (1 to 20). Then each time a button is clicked get a random number from that array, assign it to a variable then remove it from the array. I did this years ago in flash and as2. Any pointers?

      may be like this?
      local a = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20}
 
math.randomseed(os.time())
local random_number = math.random(#a)
 
print("random number", random_number,"\n")
 
local b = {}
 
for i=1, #a do
	if random_number ~= a[i] then
		b[i] = a[i]
	end
end
 
a = b
 
for _,v in pairs(a) do
	print(v)
end

      tab={1,2,5,8,10}
function click()
     local val=table.remove(tab, math.random(#tab))
     return val
end

      thanks keszegh, your example works great for my needs, except that once the table is empty then the script seems to get stuck and I get an error. Im sure there is a way to check that the table is not empty before executing the function but being new to lua I cant get a handle on it.

      if #table > 0 then
  -- use table in here
end
