Ever since I saw Rosy's video at RCBasic (where I lurk) I have been meaning to do a version in QB64.
We all know the Classic Pong and this Perspective is very amusing, to me any way!
Rosy's video, just click into it about halfway through and watch until you get an idea how it should go...
https://www.youtube.com/watch?v=jfod2O5Oq7s
I thought I'd show the evolution of my version of development over last couple of days.
So here, my starter I just get started on images and some basic ball handling:

I tighten up game to rules of Pong and show code to Johnno because I was curious about RCBasic and Rosy.

I don't like shape of those paddles and think hey this is a call to my Rectircle drawing sub!
Ah but these paddles need different collision detection basically
1. Check collision with straight edge of paddle first, collision Circle to Line Segment code.
Return ball by reversing BallDX
2. & 3. Check collision with top circle of paddle and then bottom circle.
Return ball using the angle the ball is to paddle top or bottom circle.

_Title "Profile Pong 2-0" ' b+ 2023-02-01 started inspired by Rosy game at RCBasic
'2023-02-02 1.1 fix straight up and down problem that infinitely loops.
' You can hit a ball again so long as the dx is still headed at you or 0.
' To tighten down game to actual Ping Pong Rules added variables TableTouchL and TableTouchR
' Set those to 0 when ball collides with paddle on that side. Check those when scoring points.
' Oh some sound effects would be nice.
'2023-02-02 1-2 Increase paddleR, let paddle go through table 1/2 way, blue background.
' Try nicer font...
'2023-02-03 2-0 change shape of paddle and work out collision code circle and line segment,
' collision with offset for ball radius. Add recticle draw sub for new paddle shape.
' Collision with paddle has 3 parts now:
' 1. Collision with straight part of paddle
' 2. Collision with top circle of paddle
' 3. Collision with bottom corcle part of paddle
' PaddleR was decressed since now circle parts of paddle instead of 1/2 circle.
' Now it seems too easy to beat Computer, will take care of that next!

(This post was last modified: 02-04-2023, 08:58 PM by bplus.)
Just fix one little weakness the computer has and it should be more challenging to beat.
I test this idea adding just a couple more lines to Computer Paddle positioning for version 2-3
Code: (Select All) Option _Explicit
_Title "Profile Pong 2-3" ' b+ 2023-02-01 started inspired by Rosy game at RCBasic
'2023-02-02 1.1 fix straight up and down problem that infinitely loops.
' You can hit a ball again so long as the dx is still headed at you or 0.
' To tighten down game to actual Ping Pong Rules added variables TableTouchL and TableTouchR
' Set those to 0 when ball collides with paddle on that side. Check those when scoring points.
' Oh some sound effects would be nice.
'2023-02-02 1-2 Increase paddleR, let paddle go through table 1/2 way, blue background.
' Try nicer font...
'2023-02-03 2-0 change shape of paddle and work out collision code circle and line segment,
' collision with offset for ball radius. Add recticle draw sub for new paddle shape.
' Collision with paddle has 3 parts now:
' 1. Collision with straight part of paddle
' 2. Collision with top circle of paddle
' 3. Collision with bottom corcle part of paddle
' PaddleR was decressed since now circle parts of paddle instead of 1/2 circle.
' Now it seems too easy to beat Computer, will take care of that next!
' Clean up comments.
'2023-02-03 2-2 OK attempt to make the computer a little harder to beat. ParkCompterY will keep
' computers paddle parked until the ball hits it's side of the table, then it will spring to
' action, so no more freebee points if you hit it out of ball park.
' Fix problem when last player to hit ball hits backwards like in a serve, should lose
' a point not get one! Now checking lastToHit variable and assigned Computer and Player
' Constants. Now a problem when player lobs just past table and hits computer paddle.
' Computer needs to really duck or fly! Fixed after ball crosses net computer stays above it
' until it hits table, then it gets in position to return.
'2023-02-04 2-3 Advancements from here will mostly concern AI today I have 2 Stages to outline:
' 1. Adjust height of Computer paddle to ballY AND distance from table
' a. When ballY is low to table Computer consistently fails to arc high enough to get over the net.
' Probably the #1 cause of lost points for computer.
' b. Maybe there is a height high enough that computer can use flat part of paddle or even the
' underside
' 2. Summary we save moving ComputerX for Stage 2 and can 'rush' the net.
' Maybe add some sound effects or images if anyone offers sharable items.
' Wouldn't it be interesting to do a ballistics study and plug in results/lessons/foruma for only
' a few new lines for Computer Paddle move. Not needed, it seems.
' WOW I just made one gross adjustment to ComputerY Paddle height according to ball distance to
' table and made this a very hard game for Player to score!
' I am done for now with Profile Pong with this version, 2-3.
' Rules of Profile Ping Pong (now in effect):
' On your serve or 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.

The two characters in the game are cute, look like peanuts or rather, like individual members of M&M Peanuts bag. The supermarket near my home has loads of the "family size" bags but I cannot buy it. Last year I became alergic to peanuts. It's a long story so I'm not going to bore anyone else here telling it.

Quote:Legal Service (Ping Pong)
The ball must rest on an open hand palm.
Then it must be tossed up at least 6 inches and struck
so the ball first bounces on the server's side and then
the opponent's side. If the serve is legal except that
it touches the net, it is called a let serve.
Well I must be thinking of tennis. They do call it table tennis after all.
