Serialization Design

The game will be save in a customize .dat file named with username, using JAVA build in library- DataInputStream and DataOutputStream. 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 **

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

The format for player's information comes 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.

The format for game object comes 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
