Prepare for lift off
Let's create the image first. What we need is something that looks like an underwater
view. So the main color should be blue, with a lighter shade of blue to the top resembling
sunlight shining on the water surface. I also added a light brown strip to the botom to
resemble sand.
To create this image, I used Photoshop. However, if you don't have an external image editor,
you can also create a similar image in Scratch. The most important thing to take note of is to
make the image as big as the stage, that is, 480 pixels wide and 360 pixels high.
It's also worthwhile to spend some ime lining up the let and right edges of the image,
so you won't see the break line when the image starts scrolling. Most image editors like
Photoshop have a useful ofset opion that allows you to slide a set amount of pixels in
the image horizontally and/or verically. It will be very easy to ix the edge line this way.
Unfortunately, the Scratch editor doesn't have this opion. In this case, you may want to
keep the image simple, using only straight horizontal shapes, so there won't be any height
differences. You could also try to cut the image in half and switch the halves around. This
way, you can put the edges together and fix them. The cut you made should already be
properly lined up.
This step can take some ime but mostly relies on your own creaive freedom and experience
with ediing images. Don't worry about it too much and do the best you can. It's not a big
problem if you sill see an edge at the end. Actually, it would be prety useful to see the script
that we write in acion. You could also use the resource ile that comes with this project.
