Circle crawler

2015-04-19, post № 20

programming, Pygame, Python, #around, #around the center, #black, #center, #change, #changing, #circle, #distance, #fill, #filling, #move, #movement, #moving, #red, #relation, #vec, #vector

In this program there are entities equally positioned around the center. As the entities begin to move, they can either go toward the center, away from the center or stay. You can toggle if the entities move and if the screen gets refilled. The code is based on ‘Circle Walk II’, but the calculation for the entities to move in relation to the center is achieved by using vectors.

Usage

  • ‘m’ to toggle if entities are moving,
  • ‘f’ to toggle if the screen gets refilled.

Plant mimic

I was trying to mimic plant root-growth behavior. It all starts with one root, which then has a chance to get offspring (𝟢 to 𝟦). If it gets offspring, the offspring also gets a chance for more offspring. To reduce lag there is a maximum to the currently growing roots (𝟣𝟢𝟢). Due to the random behavior, it is possible for the plant to die at the start or — theoretically — in an advanced state.

FS letters

2015-04-12, post № 18

programming, Pygame, Python, #color, #different colors, #every file, #fade, #fading, #file, #files, #filesystem, #fs, #letters, #Macintosh, #random, #red, #red letters, #user

This program goes through all the filenames from every user (it is made for Macintosh), checks the filename and counts the individual letters. Those letters are then displayed on the screen, the most common ones big and bright and the least common ones dark and small. The letters will appear in a random order.

How to use

  • If you start the program, a black screen will appear. Press ‘Space’ and the screen will get red and begin to fade. After the screen is faded out, it gets black and the program freezes (checks your whole filesystem). After this freeze the above mentioned happens (check images below).
