• isGameOver: use to handle even while user win or lose

Methods

• userfishcollision() use to handle user fish collision with other fish
• circleChecking(int[] circle1, int[] circle2) because all object is circle like shape, check is two objects overlap
• increaseSizeChecker() while user fish reach certain point increase size
• healthAndLifeChecker() use to check life and health
• mineImport() import a mine into game
• Fishmeet(): handle while two fish touch each other
• blockingArea(): block the area that do not allow user to swim cross
• add(AllObject a): adds a new GameObject to the FishGame list
• remove(AllObject a): removes a GameObject from the FishGame list
• enableCheatMode(): turns cheat mode on
• disableCheatMode(): turns cheat mode off
• addshark(): Add a shark to the FishGame list
• sharkpass(): delete everything on the way the shark passed
• updatanum()check number of fish in the screen and update
• update() updata position for every object
• load(): read the file give the user chance to play the game he saved
• save(): save the current state of game
• situationHandle(AllObject firstobject, AllObject secondObject) handle all the things that may touch together
• userFishOutOfScreenChecker()check userfish out of screen and take it back
• updataDS()updata diection and speed for each object

AllObject

The class have variable and method that will be used by most object

Variables

• x: the x coordinate of the object
• y: the y coordinate of the object
• speed: the speed of the object
• size: the size of the object
• direction: the direction of the object facing
• id: fish Id
• objtype: fish type

Methods

• ChangeSpeedAndDirection() change speed and direction for each fish this method will be override by children class
• updatePosition() update the position of the object
• getRectangle() use x and y draw a rectangle image

Fishes

Thisclass extends from AllObject class, all kind of fish class will extend this class

Variables

• initialDirection: use to decide to side to import the fish and its initial facing direction

Methods

• ChangeSpeedAndDirection(): override the method in parents class, changes speed and direction for each type of fish
• randChangeSpeedAndDirection(): override parent class;
• randDirection(): randomly decide whether fish turning side or not
• randSpeed(): randomly decide that fish is increasing or decreasing in speed.
• eat(AllObject a) handle eat event
