Lesson 4• Make your sprite glide

• Create a scary movie

Step 1: How Does the Stage Work?

• First we need to understand how the stage works…Imagine

there is a grid

covering the stage…

This is the ‘x’ line

This is the ‘y’ line

The x and the y numbers tell us the names of each

place on the stage

Step 1: How Does the Stage Work?

• First we need to understand how the stage works…

If you want to move your sprite to a

specific place, you need to

use the numbers

shown on the grid…

This point is called: X:100Y: 50

This point is called: X:-100Y: 100

What is this

point? X:Y:

What is this

point? X:Y:

Step 1: How Does the Stage Work?

If you move your mouse around the

stage, Scratch will tell you the place on the invisible grid where

your mouse is pointing - You don’t have to

work it out!

This is useful when you need to make your sprite glide to a specific place on

the stage. Just hover your mouse over the place to

see what it is called!

Step 2: Make your Character Glide

•Now that you know all about the stage, you can find out how to glide to a specific place on the stage!•Watch the tutorial

Step 2: Practice Gliding•Make the ghost glide to the places shown in the picture, just like you saw the man doing in the tutorial•When you have achieved this, put your hands on your head

Here!

…and then here!

Step 3: Revision: Adding Music• Click on the ‘Sounds’ heading

• Click on the speaker to bring up the music choices

Step 3: Revision: Adding Music• Double click on ‘Music Loops’

• Double click on a music track

Step 3: Revision: Adding Music•Click back into ‘Scripts’•Drag the ‘play sound __ until done’ onto the canvas (do not attach it to the gliding block!)•Add a ‘forever’ block and a ‘when clicked’ block to this block

You can now add music to your ghost

story.

Challenge• Click on ‘File’, ‘New’ and ‘don’t save’.• Change your cat sprite to a ghost/witch sprite.• Change the background to a spooky one.• Add a character to the bottom of the stage (this is the person

that will be frightened!).• Have your sprite glide along the top of the screen and then

down on top of the new character.• Have the character say ‘Ahhhh!’ when he/she sees the

ghost/witch.• Add spooky music to the background.• Extra task: Can you make the ghost ‘hide’ when he reaches

the other character? • Save to your USB key.
