How do I make a simple random chance button?

[THE MADCAP]

So i'm making this simulator like game where you get to play as the enemy in a FNAF Fangame. And one of the characters that i'm programing is going to teleport around the building/area. But I want his movements to be random. Every so often a button will appear and when you click it you will teleport to a random room. I've done this with the "chance dice" and the create random thing. But I noticed that everytime I do it from the beginning it's always the same path. Is there a better way to make a simple random chance button actually work? And I make them change by objects just in case you need to know. Like change instance. If you want me to be more specific then tell me.

Every game uses the same seed to generate the random numbers.
Call

randomize();

when the game starts. This function will create a new seed
