Lesson 11

Making the Screen Bigger

So far, all of our drawings have been pretty small. When we create a new program, we only have 100 lights from the left and 100 lights from the top to work with. But what if we want a little more space to draw?

Luckily, there is another function called size that can help us. It takes two attributes - width and height:

size(width, height);

So if we wanted to make our program 500 lights wide and 300 lights tall, we could write:

size(500,300);

size()

Defines the dimension of the display window width and height in units of pixels

We can also tell our program to be as big as the entire screen with the fullScreen(); command.

Up till now, I’ve been using the word lights to describe the lights on your screen. In programming, however, we use the word pixels to describe these lights. From now on, I will use that word.
