1. Movement
Game Design (Scratch)

2. Today’s Lesson Learning Objectives:
Understand what is meant by an algorithm
Create a sprite and write code to make it move and bounce
Plan a design idea for a Scratch project
Excellence I can extend Scripts in a Scratch project using my knowledge and plan an idea of my own in clear detail
Developing
I can produce scripts in Scratch and explain how they work, as well as planning my own clear idea for a project
Secure
I can following instructions to produce working scripts in Scratch and plan my own basic idea for a project
Foundation
I can produce a simple Scratch script with support and understand what a Sprite is

3. Following a recipe
What you’ll need (Variables) 60g unsalted butter 3 table spoons golden syrup 1 x 100g bar milk or dark chocolate 90g Rice Krispies
How to make them (Instructions)
Melt the chocolate
Add the butter, and stir in until melted
Add the syrup, stir
Add the Rice Krispies and gently stir in to the chocolate mix
Spoon in to a mould
Leave to cool

4. Sequencing Instructions
Today’s Task 1
Sequencing Instructions
Yes No
Open ‘Worksheet 1 Sequencing Instructions’ from LearnCoombeDean and Save As into your own area.
Look at the flowchart and decide in what order the instructions below should go in order for them to make sense:
Add strawberries and bananas
Turn on blender for 30 Seconds
Add milk and ice cream
End
Start
Is blender full?
Put on lid

5. Sequencing Instructions
Would it still ‘work’ if some statements were in a different position?
Does it matter what order the instructions are in?

6. In this unit…
Using a program called ‘Scratch’ to create computer programs (games!) Scratch lets you program (control) ‘Sprites’ using ‘blocks’ to do different things like; move, speak, touch objects, make sound, etc But… what are ‘Sprites’?

7. Sprites
Animated characters or objects that are separate from the background in a game
To create a sprite, you can:
Use the Sprite Library
Create one using the Sprite Editor
Import a sprite from a file

8. Writing a block of code
What instructions would you use if you wanted a sprite to move on the screen when you press a button on the keyboard?
How would you implement this in Scratch?

9. Movement Today’s Task 2a
Open ‘Scratch’ and use the Cat sprite given to you
Add the following ‘blocks’ of code…
Now, add the blocks of code necessary to make the sprite move in any given direction using the arrow keys (up, down, left, right)
Extension: How do you make the sprite move faster or slower?

10. Adding another sprite Today’s Task 2b
Add a new sprite from the library
Use these blocks to make your sprite…
Make the new sprite move continuously by itself when the green arrow is clicked.
Make it bounce if it hits the edge of the screen.

11. Making your own game
In this unit, you are going to make your own scratch game with…
Moving ‘Main character’
Enemies that chase you
Items to pick-up
Health / Lives / Score
Different Levels
and more of your ‘own’ ideas too!

12. Plan your own game! Today’s Task 3
It’s time to start thinking about your own project!
Open ‘Worksheet 2 Games Design’ from LearnCoombeDean + Save As into your own area
Read through the instructions and write out your ideas for a new game
You may wish to discuss ideas in pairs
