Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Open the file called Battleship game.xlsx and create a subroutine which handles the SelectionChange event for Sheet1.

Choose event

Use the drop down lists at the top of the code window.

 

The Target parameter returns a reference to the range that you select.  Add a message box which tells the user the Address of the cell they have clicked on.

Click a cell

Test your code works by clicking on a cell.

 

Write an If statement which changes the fill colour of the cell to grey and shows a message if you click an empty cell.

Missed

Your message could resemble this one.

 

Add an Else clause which changes the fill colour to red and shows a message if the cell isn't empty.

A hit

You could expand the message to say what type of ship you hit. A = aircraft carrier, B = battleship, C = cruiser, D = destroyer and S = submarine.

 

The game won't work if a user attempts to select multiple cells.  Add an If statement at the start of the subroutine which checks if the Count or CountLarge property of the target is greater than 1.  If so, display a message and exit the subroutine.

Select multiple cells

That should slow down the cheaters.

 

You could add a separate subroutine to reset the game by changing the ColorIndex property of the cells to xlNone.

Take a few shots and then save and close the file.
