CS596 Project
Design and implement a program to play the game Tetris. Your design should
permit the following options to be "easily" added to your program: previewing
the next block to appear in the pit before the current block has stopped;
allowing other shapes for blocks; starting the game with random elements in the
bottom of the pit; different size pits; allowing the user to define the rotate
left, rotate right, move right, move left, and drop keys; and allowing the
player to flip a block (two shapes come in left and right hand versions, which
can not be rotated into each other). The options need not be implemented.
Tetris
In the center of the game is a rectangular shaped pit, 10 units wide, 20 units
high. Oddly-shaped blocks appear at the top of the pit. The shapes, shown
bellow, are all combinations of connected four 1*1-cells. The block falls to
the bottom of the bit. When the block reaches the bottom of the pit it stops
moving and a new block appears at the top. While a block drops, it may be
rotated left, rotated right, moved left a column(s) or moved right a column(s).
There is a drop key that instantaneously moves a block from its current
position straight down. This saves time and one point is scored for each row a
block is dropped in this fashion. The goal of the game is to arrange blocks so
that they completely fill the horizontal rows of the pit. When a horizontal row
is completely filled with no gaps, it will disappear and the blocks in the rows
above will drop down to take their place. When a row fills the player scores
100 points. If 2 rows fill at the same time, the player scores 300 points. If 3
(4)rows fill at the same time, the player scores 600 (1000) points. The game
ends when no more blocks can be added to the pit. After 10 rows have been
filled, the next level of play is reached. The rate at which blocks fall
increases with each level.
