CONNECT AND ENGAGE
Objectives
Developing Programming and Development (learning strand) skills,
specifically:
 Understand that computers store and display shapes by using a
drawing list of locations, dimensions and other properties.
 Understand game animation is achieved by refresh/reload/update
the screen with new data at a regular time intervals.

Complete the outstanding Python game work.
Learn it
EXPLAIN AND MODEL
 Pygame is a cross-platform set of Python modules designed for
creating 2D games.
 The modules are designed to be simple, easy to use, and fun—a
key part of Pygame's ideology.
 You can read more over at http://www.pygame.org/
 Pygame was first released in 2000 and has a large community of
developers. Have a look at the Awesome section of the web site.
Pygame requires several
line of code to get things
up and running, this has
EXPLAIN AND MODEL
been provided for you in
the form of a template to
use of all your pygame
projects.
You can download the
basic template from the
internet.
Code It: Template
PRACTISE THE LEARNING
Obviously the accuracy of data affects the quality.
1. Create a folder called pygameIntro.
2. Create a new project folder called pygameCode in the
pygameIntro folder.
3. Download the template pygame to your pygameIntro
folder as basicShapes.py
Code it: Template
Obviously the accuracy of data affects the quality.
EXPLAIN AND MODEL
1. The template has two main sections:
 Game Setup: Runs once when the game loads.
 Game loop: Runs again and again (loops) 60 times a
second.
2. We'll start by making some changes to the game loop, to get
to grips with drawing basic graphics. Once we're happy with
doing this, we can start to animate them.

What is the purpose of the game setup?
Runs once when the game loads – used to setup the start of
the game.
What is the purpose of the game loop?
Runs again and again (loops) 60 times a second – links the
main game code together.
PRACTISE THE LEARNING
Run it
1.
To get started choose either Python IDLE, Mu or Thonny as your main editing program.
2.
Next, you'll need to download the project template file from the website.
3.
Finally, open the template in your chosen editor, we need to test that everything is
working.
4.
Run the template file by either using Shift-F10 or clicking Run in the menu at the top of the
screen.
5.
After a few seconds, you should see the computer create a new window that is black, 1000
x 800 pixels and closes when you tell it to.
Learn It: Screen Geometry
EXPLAIN AND MODEL
Unlike Scratch, Pygame and most
professional game engines have the
origin x = 0, y = 0 at the top left hand
corner.
In the image above, a pixel has been
placed at x=30, y=40.
EXPLAIN AND MODEL
Program it

Pygame has several built-in shapes that you can draw using simple commands.

The .draw.rect() command lets you draw a rectangle on the display. It needs a few pieces of information to be able to do this
first, which are placed in brackets. We call these parameters.

In theory you could have lots of graphics windows open. We've only got one, which we've called screen. We need to tell
pyGame that this is where the shape is to be drawn.

We can draw lines and shapes in any of 16.7 million colours. Our code has a few set up for convenient access. In the example
below, we're using a colour we've called green.

Next, there are four numbers. Let's look at that a little bit…

We need to state exactly where on the screen windows we'd like to start drawing the rectangle from. The first two digits
(50,200) tell pyGame that we want to start drawing 50 pixels from the left edge, and 200px from the top of the screen.
PRACTISE THE LEARNING
Program it
 To draw a rectangle, we also need to state the width (40px in this case)
and the height (20px) that we want our shape to be.
PRACTISE THE LEARNING
Program it
 We can draw several other basic shapes too, such as circles.
 The idea is much the same, as you can see below:

 Lines are also possible.

In your Pygame code, scroll down to line that says, your code starts here,
located about two thirds of the way down the page.
Copy the line below, underneath this line:

Let's try something else…
Remove the lines you wrote previously, and replace them with these and
run the program. Make sure they're indented into the page.

For this lesson’s assessment you are marking your own work. This will allow you see
your own progress. This process is often used for online training programmes and is
called the ‘honour’ or ‘trust system’. Obviously, the key to these systems is being
honest. Your teacher will randomly check some students work to moderate the marking.

Draw a car or house using
code made from
rectangles, circles and
lines?
Add comments below your
code from the silver task,
explaining in your own
words how RGB colours
work?
Can you create two variables
to store two new colours?
Have you researched how to
draw the shapes ellipse and
polygon? Can you draw
examples of them both shapes
using your two new colours.
