_Title "Profile Pong 3-0" ' b+ 2023-02-01 started inspired by Rosy game at RCBasic
' 2023-02-05 3-0 Starting with version 2-4 fixed for Proper serving, I redid both paddle shapes to
'circle fills and cleaned up code to that including colsolidting Paddle Collision code.
' Rules of Profile Ping Pong (now in effect):
' Ping Pong Legal Service:
' The ball must be struck so the ball first bounces on the server's side and then the
' opponent's side. Version 2-4
' On your return you must clear net and not bounce again on your side of the table.
' Opponent may or may not chooses to wait for bounce.
' Opponent should not attempt to return a ball clearly not going to hit his side of table,
' to win a point. Version 2-2 and above AI will not attempt a return until players serve or
' return hits its side of table.
Const Xmax = 1200, Ymax = 700 ' screen size
Const PaddleR = 44, BallR = 5 ' radii

Const TableY = Ymax - 80 ' table height from top screen
Const NetY = TableY - 40 ' net height from top screen
Const NetL = 598 ' net left side
Const NetR = 602 ' net right side
Const Gravity = .1 ' just about right drop
Const BallSpeed = 8 ' for ball speed
Const Player = 1 ' for scoring properly
