Tips For Memory Game

Tips for Memory Game – A simple approach Variables: • Declare THREE picturebox variables – one for the first card clicked, one for the second card clicked, one to identify the current card Eg: Dim picCard1 As Picturebox • Declare TWO integer variables – one to store whether it is the first or second click, the other to store the score. Initialise your variables: • Double-click on the form to create a form load (code that runs as soon as your program starts) • Set the integer variables to zero. Each card’s click event – for each card: • Double-click on the card to create a click event • Set the image to the picturebox picCard1.Image = My.Resources.Shrek (Note: Shrek here is just an example of the image name) • Set the tag of the picturebox to the image picCard1.Tag = “Shrek” • Set the current card picturebox to SENDER picCurrent = Sender (Note: Sender stores whichever picturebox / object has been clicked on) • Call a procedure to check for matches (Note: while you could put the actual code here, putting it in a procedure saves you from having to copy and past the code throughout the program). Create a “Check for matches” procedure: • Use the structure below to create your own procedure. You can choose the name. Private Sub pCheckMatches() Code goes in here End Sub • Use an IF statement to test to see if it’s the first click. • If it’s the first click:  Increment the click variable  Set the first card picturebox variable to the current clicked picturebox variable • Otherwise, (if it’s the second click):  Reset the click variable to zero  Set the second picturebox variable to the current clicked picturebox variable

 Use an IF statement to test to see if the first card matches the second card; you need to test their tags.  If the tags match:  Increment the score  Hide or reset the two pictureboxes back to the cover image  Otherwise, (if they don’t match):  Reset the two pictureboxes back to the cover image Delay the reset functionality: • Put a timer on your form • Set the Interval to the 1000 * the number of seconds you want to delay • Double-click on the timer to create a tick event. • Put the reset code (ie: setting the first card’s image to the cover and the second card’s image to the cover) in the Tick event • Where you previously had the reset code (ie: When the test indicate two images don’t match), start the timer. • At the end of the timer code (in the tick event) stop the timer.
