gollark: You should store the grid dimensions with the grid somewhere, and make your update code iterate over the x/y and not just memory location directly.
gollark: Or just know the width and do some maths.
gollark: Write an abstractionoid™ for it.
gollark: I generally go for laziness and make the grid loop around.
gollark: The only real issue is boundary conditions.
