2805ICT System and Software Design 3815ICT Software Engineering

The purpose of this assignment is to construct and document a Requirements Specification, Design, and Development Process for a classic computer game Tetris. You should apply, as far as possible, the software engineering techniques introduced in this course. You should employ an OO design and demonstrate capability to use advanced design patterns and tactics in your project. The following problem statement is provided. The assignment is to be conducted in groups with no more than four students in one group.

Tetris

“Tetris (Russian: Тетрис [ˈtʲetrʲɪs] or [ˈtetrʲɪs]) is a puzzle video game created by Soviet software engineer Alexey Pajitnov in 1984. It has been published by several companies for multiple platforms, most prominently during a dispute over the appropriation of the rights in the late 1980s.   After    a    significant    period    of    publication by Nintendo, the rights reverted to Pajitnov in 1996, who co-founded the Tetris Company with Henk Rogers to manage licensing.

In Tetris, players complete lines by moving differently shaped pieces (tetrominoes), which descend onto the playing field. The completed lines disappear and grant the player points, and the player can proceed to fill the vacated spaces. The game ends when the playing field is filled. The longer the player can delay this outcome, the higher their score will be. In multiplayer games, players must last longer than their opponents; in certain versions, players can inflict penalties on opponents by completing a significant number of lines. Some versions add variations on the rules, such as three-dimensional displays or a system for reserving pieces.” 1

General description

Apart from the requirements from the original game, your program should have a start up page, the start up page should contain:

1. The title of Tetris
2. The year and course code
3. The list of all students in your group
4. An exit button to exit the program
5. A score button to show top 10 players with their scores
6. A configure button. In the configure page, a player can select normal game or game with extension (explain later), and can select the size of the field, which is the area the blocks move and build, the block dropping speeds (levels). A player can also select AI game (explain later).

1 Extracted from Wikipedia Tetris – Wikipedia (21/06/2022)

• A play button to take the player to the game

Game control

During the game play period, the player will use following keys to control the game

1. Left arrow key to move falling block move left.
2. Right arrow key to move falling block move right.
3. Up arrow key to turn the falling block 90 degree clockwise.
4. Down arrow key to speed up dropping speed of the falling block
5. “P” key to pause and resume the game
6. Esc key will bring a dialog box ask if the player want to finish the game. If the user select “Yes” then return to the start page, if “No” continue game.
7. “M” key to turn on/off music and sound effects.

Game scoring

We use a simple scoring for the game. A player or AI can get points only when they eliminate lines. More lines they eliminate through one block dropping, more points they will receive. The mapping between points and number of lines removed in one round is as:

• 1 Lines = 100 points
• 2 Lines = 300 points
• 3 Lines = 600 points
• 4 Lines = 1000 points.

Game extension

The normal game has 7 different blocks and all of them contain 4 squares (as in Figure 1). The extended game will introduce two more types of blocks with 3 squares each as in Figure 2

Figure 1. The 7 different shapes of blocks in normal Tetris

Figure 2. Two more types of blocks introduced in extended game.

AI game

The game has two different play mode: player mode and AI mode. In the player mode, the player uses the keyboard to control the movement of the dropping block as described in Game control section. In the AI mode, game AI will control the movement of the dropping block, to make it move left, right, turn and speedup dropping.

A player can select different mode in the configuration page.

When a player complete a game with score in top 10, the system will ask the player to input a name, and then the name and the score can be found in the top score page.

In the gameplay page, apart from the field of the game, the dropping block, and the accumulated blocks at the bottom part of the field, the page will also need to display other information:

1. Your group number (you will get the number when you enrol in one group).
2. Current score of this play session.
3. Number of lines have been eliminated in this play session.
4. Current level.
5. Extended game or normal game
6. Player mode or AI mode
7. Next block (the shape of next dropping block when current block drops to the bottom)

Game completion

There are two ways for a game to be completed. The first is that when the field is filled with blocks and a new dropping block has no space to appear, then the game is completed. The other way is that during a game, when a player presses ESC key and then click “Yes” in the dialogue box, then the game is also completed.

Whenever a game is complete, if the score is in the top 10, the game will pop up an input dialogue box for the player to input a name. Then the name and score will appear in the top score page.

The rule is applicable for AI mode as well. But no name input is required. AI game will take “AI” as the name.

When a player completes a game with score in top 10, the system will ask the player to input a name, and then the name and the score can be found in the top score page.

• *Level ratings, 5 = excellent, 4 = good, 3 = reasonable, 2 = poor, 1 = unacceptable, 0 = none

Individual score is calculated based on the score of the submission and the student’s effort level and contribution level. Suppose the submission score is S, a student’s effort’s level is e and contribution level is

c. The student’s score is calculated based on the algorithm below: T = e + c

T	Student score
7-10	S x 100%
5-6	S x 80%
3-4	S x 40%
1-2	S x 20%
