* X.X X.X X.X.X X.X X.X.X X.X.X X.X.X.X |
* X X X |
* |
* 0 1 2 3 4 5 6 |
* |
* Except for 3 and 6, the center of each shape is one of the blots. |
* This blot is designated (0, 0). The other three blots can then be |
* described as offsets from the center. Shape 3 is the same under |
* rotation, so its center is effectively irrelevant; it has been chosen |
* so that it `sticks out' upward and leftward. Except for shape 6, |
* all the blots are contained in a box going from (-1, -1) to (+1, +1); |
* shape 6's center `wobbles' as it rotates, so that while it `sticks out' |
* rightward, its rotation---a vertical line---`sticks out' downward. |
* The containment box has to include the offset (2, 0), making the overall |
* containment box range from offset (-1, -1) to (+2, +1). (This is why |
* there is only one row above, but two rows below, the display area.) |
* |
* The game works by choosing one of these shapes at random and putting |
* its center at the middle of the first display row (row 1, column 5). |
* The shape is moved steadily downward until it collides with something: |
* either another shape, or the bottom of the board. When the shape can |
* no longer be moved downwards, it is merged into the current board. |
* At this time, any completely filled rows are elided, and blots above |
* these rows move down to make more room. A new random shape is again |
* introduced at the top of the board, and the whole process repeats. |
* The game ends when the new shape will not fit at (1, 5). |
* |
* While the shapes are falling, the user can rotate them counterclockwise |
* 90 degrees (in addition to moving them left or right), provided that the |
* rotation puts the blots in empty spaces. The table of shapes is set up |
* so that each shape contains the index of the new shape obtained by |
* rotating the current shape. Due to symmetry, each shape has exactly |
* 1, 2, or 4 rotations total; the first 7 entries in the table represent |
* the primary shapes, and the remaining 12 represent their various |
