Objective complete - mini debriefing
With this simple addiion, we brought a feeling of gameplay to the program. Before this
step, it was more like a movement simulator or a keyboard test, but now, there is actually
something to achieve. All it required was copying a script, wriing another script that we
might just as well have copied and changed, and wriing a simple collision check and efect.
Some steps in programming can be really difficult, but once the basics are set it's quite easy
to add improvements.
Adding a bomb item
We try to get the cat to the exit of the maze, but we soon run into a problem. Most likely, all
the passageways are blocked and turn out to be dead ends. There is no way to reach the exit,
because the cat can't move through walls.
How could we solve this issue? Let's make holes in the walls. We will add a bomb item that
the player can use to blast holes in the walls. That way, they can always reach the exit.
Prepare for lift off
We draw another new sprite that resembles a classic cartoon-style bomb with a sparkly fuse.
It's easier to draw the item a bit bigger than is needed and later, scale it down with a script.
This drawing can be made with the Scratch drawing tool, by performing the following steps:
1. First, create a black-filled circle.
2. Then, select the
Fill
tool.
3. Select white color for the foreground and black for the background.
4. Point and click on the upper-right of the circle to create a white highlight. This makes
the circle look round.
5. Then, select the
Brush
tool and make sure the color used for drawing is black and
the line isn't too thin.
6. Draw a short curve at the top of the ball to make a fuse.
7. Then, change the color to yellow.
8. Draw a dot at the ip of the fuse to light it.
