The Pen blocks and the Motion blocks are utilized in this project, but of
special interest are a couple blocks from the Events group. A very useful
block is the When this sprite clicked block. Even more useful and
even more frequently used are the broadcast and When I
receive blocks. Study the code in the example. Don't worry about the
Control blocks. This project can be successfully completed without them,
although it is a little nicer with them.
Alter the sample project in the following ways:
DETAILS: Keep in mind that the internal angles of a square are all 90
degrees and that the sum of all four internal angles is 360 degrees. The
ability to divide by five, six, and eight is the only other super power you need
to complete this project!
- Instead of an equilateral triangle and a square, you will draw an
equilateral pentagon, an equilateral hexagon, and an equilateral
octagon. Each will require its own button.
- Additionally, you will create a button called "CLEAR" which clears the
screen. The other buttons will not clear the screen.
- Make sure that spacing of all elements is even and that the hexagon,
octagon, and pentagon are all about the same height.
