need help generating specific random positions
So in my game i have two actors who are obstacles once they are together. They are 2 spikes and i have 3 different ways in which the spikes could be laid out, as this a endless runner, i had difficulty in trying to find a way to randomise the 3 different way the spike could be laid out. I tried using the rng but because it can only randomize 2 way in which it could be laid out . its hard. Could anybody help with this problem?
