Movement Game Design (Scratch)

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

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

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

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

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’?

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

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?

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?

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.

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!

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
