Engage thrusters
The knight will behave quite similarly to the cat sprite. It's allowed to move through the
hallways, but it can't pass through walls. That means we can reuse a lot of the scripts
we've already writen for the cat.
1. We drag both the
createMaze
listener script and the
takeStep
funcion from the
cat to the
Knight
sprite to make copies there.
2.
Then, we click on the
Knight
sprite to switch to its
Scripts editor
.
3.
To the
createMaze
listener, we add a
set size to ()
%
block and type in
12
.
This makes the knight fit the maze.
4.
At the end of this script, we add a
delete this clone
block.
You might wonder about this last step. There aren't any clones to delete, and you would
be right. There aren't any clones, not yet at least. However, we will soon write a script to
create them.
However, first we will have a look at the copied
takeStep
funcion. You may have noiced that
with the funcion
xySave
, the list has been copied as well. That's a good thing, because we
will need that list. Note that both the
cat
and the
Knight
have their own personal version of
the list. When created, it was set to be
for this sprite only
.
