QB64 Pong
« on: July 31, 2021, 05:23:26 am »
I know... This game has been "done to death"... Now it's my turn... lol

BPlus,

This was originally coded with Naalaa then SDLBasic the RCBasic and now QB64.
This is a direct conversion and may not be optimized... No. Definitely NOT optimized... for QB64.
It's playable but could do with a "once over" to bring it up to scratch.

Notes:

Computer can be easily beaten... not sure how to make it harder.
Each time the ball is hit, it will gradually, increase speed. Could be faster...
(computer controlled player is a bit too slow...)
First to 9 points.
Player is mouse controlled.
"Borrowed" your AABB from your shooter...

Looks and sounds fabulous!

Nicely commented code, this makes ball return a little unpredictable which is good thing for pong:
Code: QB64: [Select]
  1.             '   The ball hits the player's paddle
  2.             '
  3.             If RectCollide(plyX, plyY - 48, 20, 96, Int(ballX), Int(ballY), 16, 16) = 1 Then
  4.                 human = plyHit
  5.                 playerHit = 1
  6.                 _SndPlay (Hit)
  7.                 dy = (ballY - plyY) / 64
  8.                 dx = 0.5
  9.                 k = 1 / Sqr(dx * dx + dy * dy)
  10.                 ballDX = k * dx
  11.                 ballDY = k * dy
  12.                 ballSpeed = ballSpeed * 1.1
  13.                 If ballSpeed > maxSpeed Then ballSpeed = maxSpeed
  14.             End If
  15.  
  16.  

You are right it could be faster.

The object of the original Naalaa version was to start slowly and slightly speed up with each ball strike until it reaches a preset maximum speed. Setting the initial and maxSpeed or changing the ballSpeed multiplier from 1.1 to something higher is not a problem. It's the speed of the computer's paddle. It is designed so as to "lag" to give the player a chance to win. It doesn't take long before the player can "out wit" the computer. That kind of puts a "wet blanket" on the game's "flow". I will continue to experiment and if I find the "lag factor", and can successfully change it, I will let you know... In the meantime.... It's always a mean time for coffee...

Very cool... But I would find it a bit difficult to code a game like that one... lol

I dunno... If you swap the lawn or clay surface to something much colder and smoother.... This game reminds me of another... Can't quite put my finger on it... lol

The fill circle function is quite fast. Two paddles and a fast moving ball... Have you tested the number of circles before lagging occurs? Homework...

I like the "Help Me" option... Unlike most 'tennis' games, I could actually hit the ball more than once... nice feature.

In regards to graphics, would I be correct in assuming that, curved paddles would be preferred so as to maintain an air of unpredictability?
Originally, you had the player setup as a rectangle... But, calculating the distance between two circles, would be quicker than including collision detection... Cool...
If ever you decided to use collision detection, you could use AABB, because the ball is quite small and can be treated as a square... On the subject of the ball... The colour could be white, yellow or even lime green. Steer clear or black. Black would make it look like a puck. Puck? Interesting... Just a thought...

Speaking of lawn and clay... perhaps either allowing the player to choose or randomly select a surface could effect the player's "friction". eg: if the surface is clay, then the surface friction is less - similar to ice but not so much - ice? Interesting.... and the lawn would have greater friction so as to make player movement more responsive... Just another though...

Here's another weird thought... I know... three in one day... Who knew?  lol  If the player is using the 'easier' paddles then perhaps the player's paddle can reduce in size with each ball strike... Striker? Interesting... Just yet another thought...  I'm going to stop there. Fear of wearing out the old grey matter is reason enough... But, the best reason is, coffee...

Have a great day!

Bplus.

In regards to graphics... I'm toying with the idea of a horror/comedy look... Just a concept... Player is a zombie the computer is an eyeball and the ball is a skull... With the right backing track, sound effects, images and fonts (all free of course) it could make for an amusing project... Not 100% certain of success but might be good for a giggle... Also testing a simple menu operated by arrows and space keys... another crazy thought... Have critters walk across the players side of the court. If the player can hit them with the "ball" then a game point is removed from the computer...  anyway... best get the game working before adding more stuff... This could be fun...

I can take no credit. It was merely a modification of the original Naalaa listing by Marcus Johannsen.
