In this project we will draw a sprite and then code it to follow our mouse around the screen and create a trail behind it with some added effects.

Create a new sprite and draw a shape. It can be any shape and any colour you like. Keep it small and drag it into the center of the box.

Scratch: How to create your own sprite

---

You can create your own sprites using the sprite editor. To create a new sprite put your mouse over the Choose a Sprite button and then click on the paintbrush.

This create a blank sprite and will open the sprite editor where you can use the tools to create your sprite. You can even create extra costumes for your sprite!

Tip: give your sprite a name so that you can recognise it in the code blocks.

To make the snake pattern we will code the sprite to follow your mouse around the stage area.

Add the following code to the sprite to make it start at a random position and then follow your mouse pointer.

Click on the green flag and your sprite should follow your mouse around.

To make the trailing snake effect we will create clones of our sprite, leave them where they were created and then delete them after 5 seconds.

Add the following new code blocks to your sprite.

Click on the green flag and the clones should make a snake effect before deleting after 5 seconds.

To make it look even better add a change [color] effect by 5  block underneath the create clone of [myself] block. This will change the color of the original sprite after each time a clone is created.

Click on the green flag and snake should me multicoloured now.
