Tetris

This is a python version of the famous tetris game amde for my father as a birthday gift. We used to play WinTETRIS battles when I was waaaay younger. So now I want to gift him this little game that he can enjoy on every computer he uses.

Features to implement

• Implement the scoringsystem of the original Tetris (MS Entertainment Pack for Windows)
  • Piecedrop gives certain amount of points
  • More actions, turning and moving a piece, the less additional points
• Preview the next piece
• Clear Rows once they are complete
• Hold the right-, left-, or uparrow to move the piece
• Adapt colors from original WinTETRIS:
  • L-Shape, yellow
  • J-Shape, pink
  • I-Shape, red
  • S-Shape, darkblue
  • Z-Shape, green
  • O-Shape, lightblue
  • T-Shape, gray
• Build Shortcuts
  • F2 - new game
  • F3 - pause the game
    • F3 - pasuing shows a big text PAUSE

To Do's

• Remove visible grid
• Gray Border like in this image.
• Gray Inforbox to the left of the palying grid
• Show levels, next piece and score in the gray Box to the left of the Playinggrid
• Background should match the levelimages from original "WinTETRIS"
• Build a main menu:
  • Selection, quit or start the game
  • Advance in the menu to a section where you can select your starting-level
  • Build in back navigation
  • Menupoint to change the keyboard settings
    • Droping a piece
    • Move piece left
    • Move piece right
    • Rotate piece
  • After the game is finished, drop back to the main menu
• Find out how many points you get per dropoff of a piece and cleared rows per level
• Add some photos to the README.md, so people can see what the game looks like
• Adopt the 30 FPS in the game, Change the clock settings

Scoring System

According to the tetris.wiki the Tetris in the Microsoft Entertainment Pack has the following scoring system:

• Each piece has an initial score value and decreases with each rotation and horizontal move
• A piece has an initial score value, which decreases on:
  • Rotation or
  • horizontal moves
• Dropping the piece increases the score value of the piece, proportionaly to the distance it falls.

Bonuses for clearing rows:

Row	Points
1	100
2	200
3	400
4	800

Known Issues aka Features ;)

• Rows are not cleared Wrote a function that clears rows

• The window can't be closed with the X-Button in the top right corner Included asking for the eventtype pygame.QUIT

• Sometimes pieces that were dropped can still be moved for a fraction of a second Returns now true for change_piece immediatly after dropping the piece. Reduces some loading time

• Occasionally after a row is cleared, the rest does not fall down

• The I shape should only rotate one time clock- and one time counterclockwise

Lessons Learned

• Getting to experiment with PyGame
• Clean Code Using PyLint for Style Guide Checks in TravisCI
  • Getting knowledge of PIP8 Style Guide (Unnecessary parens, naming conventions, )
  • Avoid using global variables
