This is a fully working pong game, almost identical to the origional one. It has a fairly good (but very basic) computer player, and the ball deflects at different angles depending on how far away from the center of the paddle it is.
I just reposted this, so the code is posted instead of a zip file, that way every body can view it.
Assumes
'1: Create a new project, and shape form1 so it's width is longer then its height
'2: Add a timer, named timer1, with an interval of 1
'3: add 5 shapes, named shpWallTop, shpWallBottom, shpBall, shpPlayer1 and shpPlayer2
'4: make shpWallTop and shpWallBottom's width the same as the form's width
'5: make shpWallTop and shpWallBottom as wide as the form, with a height of about 300
'6: put shpWallTop at the top of the form, and shpWallBottom at the bottom
'7: Make shpBall a square with a width of 255
'8: make shpPlayer1 and shpPlayer2 's height about 900, and width about 255
'9: place shpPlayer1 about 1 cm from the left side of the form, and shpPlayer2 about 1 cm from the right side.
'10: Paist the following code into the project:
VBcodersDim vmom As Integer 'vertical momentum
Dim hmom As Integer 'horizontal momentum
Dim padSpeed As Integer 'the speed of the players paddle
Dim origPaddleLoc As Integer
Dim origBallLocY As Integer
Dim origBallLocX As Integer
Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
If KeyCode = 38 Then 'the up key
padSpeed = -150
