Serialization Design

The game will be save in a customize .txt file named with username, using JAVA build in library- PrintWriter and BufferedReader. The game will load/save the file once the player envoke the correspond save/load button

The first line of file will consist of the amount of time left at the current level:

Note:

If the amount of time left is equal to 0. In another phrase the user saved at the end of a level. The file will simply save the game at the **next level ** with the exception that it is already the end of game

The second line of file will consist of a number indicate the current level

The third line of file will consist the difficulty level of the game in String, such as {easy,medium,hard}

The fourth line consist a number indicate number of player

A string of ###user will come before every string line consist of user information

The format for player's information comes in a string line with username; shipSkin; totalCoins; current score in the level; UpperLeftXPosition; UpperLeftPosition; deltaX; deltaY; and additional affects on the player separate by a colon. Additionally, information for additional affects will be separate by commas according to the additional affect type within the colons

The line after player's information consist the number of game Object

Note: this will only appear if the player did not save at the end of game.

A string of ###gameobject will come before every string line consist of game object The format for game object comes in a string line with object type; specific Object Type; UpperLeftXPosition; UpperLeftYposition; deltaX; delatY; and additional affects on the object, each separate by a colon. Additionally, information for additional affects will be separate by commas within the colons.

The file ends with ENDL#, indicate the end of a files
