In-Depth Information
For this stage, an external image editor will be very useful because we want to load all the
different images as separate costumes. You can do it in Scratch, but you'll be doing a lot of
erasing to only leave one image per costume. You'll also see that most sprite sheets only
show images facing in one direcion. We want to have separate images for both direcions,
so we will need to mirror most of them to face the other side as well.

Let's first look at the method that uses an external editor:
1. Start your preferred editor and load the sprite sheet.
2. Cut out each sprite that you want to use and save it separately. Make sure that
the area around the sprite is transparent, so you don't end up with a colored box
surrounding your character sprite.
3. If needed, make mirrored copies of all the images facing in the other direcion.
This will be necessary for all of the images that aren't facing straight up or down.
4. Double-check to make sure that your collecion of separated sprites describe a full
circle in approximately equal steps.
With the images ready to be loaded, we can start adding them to Scratch by using the
following steps:
1. In Scratch, create a new sprite and name it
kart1
.
2. Click on the
New costume
link to open the drop-down menu.
3. Select the
Import
opion.
4. Select and import the first sprite costume.
5.
Click on the
Set Costume Center
icon and place the center point at the botom
of the image between the wheels; see the following screenshot:
