Oh, it was the graphics system, thank you guys so much for helping!

And also, I am trying to get an int but it always just returns 0. Maybe it is something with the graphics system because I had to use love.graphics.print() instead of just print().

Hi, sorry I did not include code. How should I send it?

I can't get love.math.random() to generate a real random number. It only generates 0. It is in the love.load() function but it does not work.
