Refactoring

Use of OO design pattern

• State design pattern

State design pattern is used in the GameEngine class in the GameState package. Divide GameEngine into playState and debugState. move() and debug() methods are controlled by different state. Reduce if else statements.

• Factory design pattern

Factory design pattern is used in the Dialog package. DialogFactory class is instantiate in GameController class to generate different type dialogs. Reduce code duplication and become more maintainable.

• Singleton design pattern

Singleton design pattern is used in the Music package. Include two BGMs, interface sound effects and game sound effects. All those classes are called play/stop by Controller classes. Game music effects are used in move(). Improve the efficiency of the game, without having to load music resources every time.

Use of GUI design patterns

• MVC design pattern

MVC design patterns are implemented in the project. For example, game.fxml is the view, GameEngine class is the model and GameConroller class is the controller that modify the data in the model and updates the view. Here are two MVC examples in the game. Make the structure of game simpler, enable code reuse.

• Code and view are separated

The code and views of all the JavaFX scenes in the game are separated clearly. Use css to improve the UI design.

Refactoring Methodologies (Difficult to give example, all bad-smell source code is re-factored)

• “SOLID” Design Principles are considered during coding.
• Extract Method From A Larger Block of Code
• Simplifying Methods
• Replace Temporary with Query
• Replace Parameter with Explicit Method
• etc.

Maven Use

Maven is used in the project. Make it easy to download dependencies when other developers start work on the code.

The .jar file built by Maven. Run successfully in IDEA.

Fixing Errors

All the errors in the source code are fixed, including save(), load(), toggle music(), etc. They have been fixed and refined according to my design requirements. These method are all in the GameController class. This is a part of "Corrective Maintenance".

Additions

There are 14 new features in the game.

1. Start Animation Screen

First scene of the game. Players can enjoy animation and music until they click the screen to enter the Menu scene.

2. Start Menu Screen

Menu scene of the game, user can click one of the buttons to enter another scene.

3. Select Archive Screen

Player can have three different archives in this game. If the slot is empty, player can create new archive, set the nickname. The player’s game progress is also displayed. e.g. 4/8 Level is in 4th level. Click the non-empty slot, continue to play the game! Click the "ERASE SLOT" to the erase screen.

4. Erase Archive Screen

Click a slot button to erase the corresponding archive. If the slot is not empty, player needs to do a confirmation; otherwise, there is a warning dialog.

5. Setting Screen

Player can turn on/off the sound effects(keeper walk/impact crate/impact wall) in the game and change the crate skin to different color.

6. Help Screen

Show the operation guide.

7. Ranking Screen

Show the ranking, including the player's nickname, total move count and move count for each level. When mouse enter the label, the size will change.

8. Game Screen Refine

Add the Level_Move in the upper left corner. Add options that can return to menu and go to select level scene (Save the game automatically if do those operations). User need to confirm the reset operation. Toggle music can turn on/off the BGM. Refine the game GUI.

9. Game Sound Effects

Add game sound effects, including walk, impact crates, impact walls. The game sound effects can turn on/off in the setting scene.

10. Interface Sound Effects

All the button and interface element are bind with corresponding sound to make more user-friendly.

11. Game Pause Feature

When in the game scene, press ESC in the keyboard, player can pause the game. When the game is paused, press ESC again to resume the game or press F1 save the game and return to menu.

12. Add 3 New Levels

Design three new levels to the game.

13. Select Level Feature

The player can return to the previous level, but the state will remain in the state of level_completed. If the player wants to replay a certain level, he needs to perform a reset level operation. But this means giving up the previous results, and will change the highest level of the archive (for example, from the eighth level back to the fourth level, he cannot return to the eighth level after reset, but the completion status of levels 5, 6, and 7 will not be affected).

Go back to level 4.

Reset and select level. Cannot select levels after level 4.

14. Tutorial Screen

Play the concise tutorial video of the game. (The video added in the game now is very rough.)
