After having programmed my own Tetris clone — Jetris —, I thought of another game to clone. A really fun and fairly simple game came to my mind: Pong.
After a few hours I managed to do it and here it is.
I even implemented the computer being able to play, although it never loses… If a hitter is controlled by the computer is indicated by its color (green for players, red for the computer).
To get more information about Pong, visit this Wikipedia entry.

Controls (general)

  • Escape pauses and unpauses the game,
  • ‘r’ resets the game.

Controls (left player)

  • ‘w’ moves the (left) hitter up,
  • ‘s’ moves the (left) hitter down,
  • Left arrow key while pause changes if player is computer or user controlled.

Controls (right player)

  • Up arrow key moves the (right) hitter up,
  • Down arrow key moves the (right) hitter down,
  • Right arrow key while pause changes if player is computer or user controlled.

Being generally very interested in games I recently stumbled across a Tetris clone, Quadrapassel. It really cought my attention and after playing for a long time I decided to program a Tetris clone myself.
There may still be a few inconsistencies but all in all I think it works very well.
Your game score will be shown in the window’s caption along with the info if the game is over yet.
To see further details about Tetris, visit this Wikipedia entry.

Controls

  • Left arrow key to move the brick to the left,
  • Right arrow key to move brick to the right,
  • Up arrow key to rotate the brick (clockwise),
  • Down arrow to increase the brick’s fall speed,
  • Space to bring the brick to the far bottom,
  • Escape to pause and unpause the game,
  • Tab to toggle if a fake brick is shown where the brick will land,
  • Right shift to toggle brick looks,
  • Backspace to start a new game.

‘Grow’ is an animated gif I made. It is about a seed getting planted and wants to rise up to the sky but then gets struck by lightning and its ash falls back down on earth.

Boxes

Inspired by a pattern on a storage box I own I decided to try program something simulating it. This program shows variously colored boxes with a black gap in between. You can adjust the box size, the gap size and even how many boxes will appear on the screen (all changeable in the code).
The pattern will be newly generated every half a second.

Prime Spiral

Being fascinated by prime numbers I wanted to create a prime number spiral generator myself. It just goes through the numbers from 𝟢 to and checks if they are prime. If they are prime, this rectangle in the spiral gets lit red, if it is not prime it gets lit dark gray. Because my algorithm for prime checking is very basic, I implemented a performance helper. That way the spiral’s creation will slow down after time (due to the numbers that need to be checked getting bigger and bigger). The really interesting thing is, that — although they may seem random — prime numbers often form lines if shown in such a spiral. To see the comparison I included an image of a randomly (𝟧𝟢 % to 𝟧𝟢 %) lit up board.

JClock II

This is an alternative clock design. Version two is even prettier to look at.
Instead of a few clock hands spinning their circles, every hour, minute, second and centisecond is represented as differently colored circles on four imagined circles around the center. That way you have a visualization by quantity, not by position.

This clock face would represent 21:46:42.

How to read the clock

  • 𝟤𝟣 green circles represents 𝟤𝟣 hours,
  • 𝟦𝟨 teal circles represents 𝟦𝟨 minutes,
  • 𝟦𝟤 blue circles represents 𝟦𝟤 seconds,
  • some white circles represents centiseconds (one hundredth of a second, mainly for the look);
  • current time: 21:46:42.

Colors VI

This sixth version of my ‘Colors’ program has only a few improvements. At first it uses a different method to change the individual pixels. Instead of using pygame.PixelArray() it calls on the surface .set_at(). Also you get an indicator if it has finished drawing (to be seen in the caption). At last it always — not needing a user input — saves the drawing if it is finished.
To get more information on my ‘Colors’ program, see ‘Colors V’.
