How can I make a simple random script. For example I have a value and I want to change the value to either 1 or 2 and to do that you have a 50/50 change for each how would I do that?

#2

You would simply do math.random(1, 2):

How would I use that as a random if statement? such as 50 percent to do something and 50 percent to do something else.

if math.random(1, 2) == 1 then
    -- code
else
  -- code
end

If you wanted to have 3 options, you could include an elseif as well, but you would have to store the random in a variable like so:

local chance = math.random(1, 3)

if chance == 1 then
    -- code
elseif chance == 2 then
    -- code
else
    -- code
end
