I want to get three random values from a one dimension array, without any repeating value. It's easy to get one random value by creating a random number but how do I create second and third random numbers without te risk of getting the same value before?
In fact what I'm trying to do is creating an npc dialogue system in which there are 10 chat topics but the game randomly selects three of these. So the player will select a chat subject among these three. Can you think of a different and better approach to carry out this in Construct 2?
