Tetris game and bot for playing Tetris

Implementing

• Piece Abstraction
• Board Abstraction
• Rotation that is CCW
• Use SRS for board (Most confusing part)

Bugs/Fixing/Todo

Todo

• Implement dropHeight method

Fixes

• Use the Sanity checks provided
• The I needs to be lifted up a y value at creation to fix weird rotation Behavior

Major Bugs

• Witnessed rotation on final drop eliminated the block of another value (Could be wallkicks)
• Moving left/right when piece is at bottom leads to index out of bounds

Resources

• PDF
• Model Game
• Genetic Algorithm

Fixing Last Lab - Our Issues

Negatives

• Code failed some cases
• More commenting (particularly on utility methods)
• Report may have been a little too terse
• More explicit discussion of edge-cases
• Degroup Test cases

Positives

• Good test coverage of positive/negative and unit/integration tests
• He was impressed by brevity (shortest report of all)

Assumptions

• We assumed pieces would be given in a certain way - every time. (The way being how they are written in JTetris) (This probably our biggest and most dangerous assumption)
• We assumed their would only be 7 different pieces, and thus 3 different classifications for them (Square, "I", Other)
• We assumed a board would have to be at least 4x4 (to fit the "I") piece, if not we throw an error
• For the clockwise function we assume that the object will have 4 rotations (excluding Square) so we can call counterclockwise 3 times
