In the word game Hangman, a player tries to guess the letters of a hidden word:
The word to be guessed is "hidden" by dint of the fact that it's written in white font on a white background!
Write VBA code to allow you to play the game with a friend (your computer, possibly). A good start would be to hide all of the shapes which make up the gallows, using code something like this:
Dim GallowsShape As Shape
For Each GallowsShape In ActiveSheet.Shapes
'hide the next shape in the gallows
GallowsShape.Visible = msoFalse
Note that when you loop over a collection of shapes, you have to prefix the name of the Shapes collection with a reference to the worksheet which contains them.
Here are some ideas for functions (not subroutines) that you could include in your code. If you're not sure of the difference between a function and a subroutine, see the relevant pages in your courseware manual.
|What the function could do||Value returned||Data type|
|Loop over the shapes in the gallows to determine if any remain invisible.||True if the player still has more guesses left; False otherwise||Boolean|
|Loop over the cells in the word to be guessed, determining if any remain white.||True if the word has been fully guessed; False if some letters remain invisible.||Boolean|
When you've finished, save your file as Hangman with answers. Before closing it down, you might like to show it off to your trainer!
