Code:

math.randomseed(os.time())
x = math.random(0,10)
y = math.random(0,10)

Is it possible that x equals y by using this code? If so, how do I make sure that y does not equal x while getting a random number from 0 -10?

Thanks in advance.

Will the following work?
Edit:

Code:

math.randomseed(os.time())
x = math.random(0,10)
y = math.random(0,10)
if y == x then
while y == x do
y = math.random(0,10)
end
end

Yes, it is possible.

Code:

math.randomseed(os.time())
local x = math.random(0,10)
local y = math.random(0,10)
while x == y do y = math.random(0,10) end

Now, x will never equal y after that line of code.
This might not be the best way. If this were a true random number generator, I suppose it's possible for the program to be stuck there forever; however, I wouldn't worry about it that much.

Got it, thank you for the reply. Very Happy
