Main entry point of the library.
Defines the main data structure of the game — GameData and possible operations on it.
◆ GameState
Enumeration of all states of the game's Finite State Machine.
| Enumerator |
|---|
| START | Start screen of the game.
Transitions to @ref SPAWN_START when the user action @ref Start is
received.
|
| SPAWN_START | Spawn a random first piece and generate a random next piece.
Different from @ref SPAWN because the spawned piece is random and not the
next piece.
Entered from @ref START and @ref GAME_OVER for the first spawn of the
game.
Transitions to @ref MOVING after the piece has been spawned.
|
| SPAWN | Spawn the next piece and generate a new random next piece.
Applies spawn delay proportional to the distance of the attached piece
from the ground. The higher the piece was attached, the longer the delay,
to provide the player with ample time to think when they are close
to losing.
Transitions to @ref GAME_OVER if there is not enough space for the spawned
piece.
Otherwise, transitions to @ref MOVING after the piece has been spawned.
|
| MOVING | Main state of the game, the player is in control of the piece.
The played piece is rotated and moved sideways or downwards according to
player's inputs.
The piece is also automatically moved downwards at fixed intervals. The
intervals get progressively shorter at higher levels.
Transitions to @ref ATTACHING when the piece touches the ground.
|
| ATTACHING | The played piece is attached to the field.
Transitions to @ref CLEARING if the attached piece completes one or more
lines.
Otherwise, transitions to @ref SPAWN.
|
| CLEARING | Full lines are cleared and points are awarded.
Plays a quick animation of the lines clearing and moves the lines above
down.
Points are awarded based on amount of lines cleared according to the table
below:
| Lines Cleared | Points Awarded |
| ------------- | -------------- |
| 1 | 100 |
| 2 | 300 |
| 3 | 700 |
| 4 | 1500 |
Transitions to @ref SPAWN
|
| GAME_OVER | Game over screen of the game.
Transitions to @ref SPAWN_START when the user action @ref Start is
received.
