Hello. I am trying to make a game of snake.  There will be a question displaying on the top and I want it to be random. When the user uses his snake to eat the target food successfully, I want the question to regenerate into a different question. I have used a varible called "questions" and it works with the random() function. Before Void Setup, I have a line telling it to generate  

float questions = random(1, 3);

int question = int(questions);

. I want to tell the program that when ever my snake touches my target food, it should regenerate the question and how do I do that? Thanks.
