Tetris-Redux

modified version of tetris

A high-level description of each of your public member functions in my classes

Class Well

• Well – Constructor
• ~Well – Destructor (unnecessary)
• emptyWell – this function is to restart the tetris board once a level is complete, it clears the board and allows for the new game to begin. I placed this in Well class because it dealt directly with the well object
• updateTet – updates the coordinate with a given character, placed in the Well class because it directly modified the well behavior.
• viewTet – This function allows the user to view the coordinate of the tetris board without modifying it, which is why it is constant
• floors – deals with the most important part of the game, removing of completed floors. It tracks how many floors have been filled and returns the amount to be removed.

Class Game

• Game – Constructor, initialized almost everything
• ~Game – for pointer destruction
• Play - work horse of the game. Starts a timer which is what the entire function is revolving around, if a certain time elapses from a moment when time is measured, a piece drops. This function waits on key inputs and is in charge of updating variables revolving around playing individual levels.
• playOneLevel – rather unnecessary, behaves as a helper function. Returns true if the player has removed the required level count.
• DisplayPrompt – instructs user on what to do next, displays string
• displayStatus – displays level, rows left, and score
• getRandPiece – assigns a random piece type to a pointer

Class Piece & Children

• Piece – initializer for drop location and orientation
• pDisplay – made virtual because each child displays something different
• PieceInWell – places a tetris piece into the game at X=3, Y=0, with default orientation.
• nextPieceDisplay – used only for the display portion of the game, prints the next tetris piece in line.
• Rotate – changes the orientation of the tetris piece
• pieceFall – moves the tetris piece down one coordinate if it is allowable. This function determines if it can move into the position or not.
• moveLeft – moves the tetris piece to the left, if allowable. Virtual because the crazy piece moves to the right
• moveRight – moves the tetris piece to right, if allowable. Virtual because the crazy piece moves to left.
• placePiece – virtual function because of the foam piece and the vapor piece. Otherwise it turns the tetris piece into bricks once it has reached a lower bound.

Design decisions and assumptions made

• I assumed that the tetris board cannot be changed. It will remain the dimensions specified in the spec. I used vectors for my first 3 attempts. But I bit off more than I could chew and made my code more complicated than it had to be. I’m pretty happy with the final result though. Given another couple of hours. I think I could have worked out the foam bomb and any potential bugs I didn’t catch. I also assumed the play another level function was simply a helper function. It was kind of redundant to use it when a simple if statement did the same thing. Testing it was time consuming because I had to play tetris.

• Side Note :I had an interesting bug where the right most of my well wasn’t being cleared. I didn’t realize because when I play tetris. The right most column is where I place my I pieces for clearing the board. I fixed it.
