For the final week we are going to convert the Christmas Card into a Christmas Game.
We will be starting with the Christmas Card that we made last week, if you weren’t there or want to start with the same one that I will be using, have a look at the bottom of this document, I have added instructions on how to get it.
The Plan for this week.
We will be adding some additional Sprites. We will be using Scratch Sprites rather than drawing our own to save time.
- A sprite for Santa’s sleigh
- This will move backwards and forward across the top of the screen
- A sprite for the Presents
- This will fall from Santa’s sleigh to the bottom of the screen, not directly down though.
- This sprite will have many costumes.
- As sprite for you
- You will be able to move Left and Right across the bottom of the screen to try and catch the falling presents.
The Sleigh Sprite
Scratch does not have a sleigh sprite, so I used the reindeer.
He needs to start on the top left of the screen and move all the way to the top right of the screen and then turn around and go back to the top left, he will just keep doing this.
The code might look something like this:
The Present Sprite
We might have to draw this one.
The present Sprite will start from wherever the Sleigh Sprite is glide down to a random place at the bottom of the Screen, you can make the Present a random size as well to make it more interesting.
The is a Scratch block to put one Sprite in the same place as another Sprite So the code to move down the screen will look something like this:
There will also be code to count the number of presents caught. So, if the Present Sprite touches you, it will count as being caught, so you can increase your score.
When the present is caught you can change to a random costume to display the unwrapped present.
I’ll let you figure out this code as a little challenge (I haven’t done it yet 😊 )
You Sprite
This is the one that catches the presents. I used the Scratch cat, finally.
Not much code for this one, he just needs to move left or right using the left or right keys on the keyboard. So, something like this:
Getting the Christmas Card project.

You will then have to save it to your device, select File – Save to your computer, so you can work on your version.
Now you will have to open Scratch 3 on your device and open the file you just saved.
