Games with Turtle Graphics

In the previous post — Animation with Turtle Graphics — I explained that animation is simply simulation, making stuff appear real. You create the appearance of real and continuous movement by quickly showing a series of slightly-different images. I then introduced the idea of creating animations with Python’s turtle graphics module. In this post, I’ll use a simple example to explain how to use animation as well as user interaction and data to create a game with turtle graphics.

Animation with Turtle Graphics

All animation (indeed, all moving pictures) is fundamentally nothing more than consecutive pictures being shown so quickly that it simulates continuous motion. Each picture is called a frame. Each frame must differ from the previous one slightly, and quickly showing the frames one after the other gives the illusion of continuous motion, hence the word ‘animate’ as in ‘bring to life’. The frames have to be shown at a rate of about 12 or more frames per second (fps) for a person to experience them as an animation. Modern film generally uses 24 frames per second.

Programming with Understanding

You can’t learn to speak — to say things — without learning to say something. And you can’t learn to program — to talk to a computer — without learning to program something. Learning to program therefore not only provides the opportunity to learn to instruct a computer, but is also an opportunity to learn about everything else in the world.

When learning something new, by coming to understand its fundamental elements or building blocks you’ll not only learn more, and more exciting things, but have a greater amount of expressive power with that knowledge. It is essential, however, that the process of learning those detailed fundamentals takes place with the big picture always in mind, and in sight. Literally as well: appropriate visuals greatly improve the learning process by serving as memory and reasoning aids.

Does Easy Do It?

What is best about the best games is that they draw kids into some very hard learning. Did you ever hear a game advertised as being easy? What is worst about school curriculum is the fragmentation of knowledge into little pieces.

This is supposed to make learning easy, but often ends up depriving knowledge of personal meaning and making it boring. Ask a few kids: the reason most don’t like school is not that the work is too hard, but that it is utterly boring.
