this is a simple game of pong controls are the up and down arrow keys Code: View.Set ("offscreenonly") var ballx, bally : int := 200 var xchange, ychange : int := 1 var paddley : int var chars : array char of boolean var score := 0 paddley := 170 loop Input.KeyDown (chars) drawfillbox (0, 0, maxx, maxy, black) drawfilloval (ballx, bally, 5, 5, white) delay (0) drawfillbox (10, paddley, 20, paddley + 80, white) View.Update ballx += xchange bally += ychange if bally > 389 then ychange := -1 end if if bally < 5 then ychange := 1 end if if ballx > 634 then xchange := -1 end if if ballx < 20 and bally > paddley and bally < paddley + 80 then xchange := 1 score +=1 end if if ballx < 0 then ballx := 500 bally := 200 end if %%%%%%%%%%%%%%%%%%%%%%%paddle movement%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% if chars (KEY_UP_ARROW) then paddley += 1 end if if chars (KEY_DOWN_ARROW) then paddley -= 1 end if if paddley > 319 then paddley := 319 end if if paddley < 0 then paddley := 0 end if end loop Try it out and respond with what you guys thought of the program |

Not a bad start, the game-play is there. I suggest maybe slowing it down a touch, and using getch to let the user hit a key before it starts. After that, a good next step might be to split the paddle up into segments such that if it bounces off the middle segment, the ball's path can be reflected along the paddle's normal, and segments moving away from the center would reflect the ball at wider angles. Do you have any plans to add AI/an extra player? |

Thanks for the feed back!!! About the speed, My laptop runs the program slower than others so I don't know by how much to slow it down. Also I plan on adding an intro screen and an ai/second player in the future. (I just don't know how to program an a/i yet) I'll post a revised version of the game under this topic. Thanks for playing!!  |

As promised, here is the code for the revised (now 2 player) game of pong. Player 1 is on the left side and the controls are w, and s. Player 2 is on the right side and the controls are the up and down arrow keys The game counts the score up to 10 then states who won. Please post a reply of what you guys thought of the revised game! Thanks for playing!!! |

I think a delay (2) or (3) is good enough. The only things I would like to see: - an AI - a menu with choices of AI or 2-P or a 3/4-P, or even a survival game where you constantly ramp the speed or something 
- game speed option |

A working pong AI is ridiculously easy to make. If the ball is above the AI's paddle, move the paddle up. If it's below, move the paddle down. Of course, you can make it a bit more fun by determining when the AI makes 'mistakes' and when it doesn't. Maybe it moves in the wrong direction, maybe it moves too fast or too slow. |

Thanks for the feed back. I like the idea of a survival mode. Upgrades for the next version: a/i, survival mode, and hopefully sound fx's Thanks for playing! |
