math.random - question.

[EnglishMan]

Hi, I have a question. How to make the math.random function not be able to draw twice the same number in a row? Sorry for my English, I'm not from this country.

after randomize it, save the last result in a variable. With the next randomization you will have to check if the new value is not the same as the old one.

local lastRandomResult


local randomResult
repeat
  randomResult = math.random() 
until lastRandomResult ~= randomResult

lastRandomResult = randomResult
