Method Details

gameOver

public boolean gameOver()

signals to game engine that the game has finished by game over. called every game loop. default implementation is always false.

Specified by:

gameOver in class Playground

Returns:

false

levelFinished

public boolean levelFinished()

signals to game engine that the game has finished by success. called every game loop. default implementation is always false.

Specified by:

levelFinished in class Playground

Returns:

false

resetRequested

public boolean resetRequested()

signals to game engine that the game has been requested to be reseted (restart). called every game loop. default implementation is always false.

Returns:

false

redrawLevel

public void redrawLevel(Graphics2D g)

unimplemented empty method called by game engine every loop.

Specified by:

redrawLevel in class Playground

Parameters:

g - Graphics2D abstract drawing object of java Swing, used to carry out all drawing operations.

preferredSizeX

public int preferredSizeX()

Signal that the level has a size of 700x700 pixels.

Specified by:

preferredSizeX in class Playground

Returns:

x size of level 700

preferredSizeY

public int preferredSizeY()

Signal that the level has a size of 700x700 pixels.

Specified by:

preferredSizeY in class Playground

Returns:

y size of level 700

applyGameLogic

public void applyGameLogic()

checks for interactions between GameObjects; notably ball with ego and ball with brick. In case of detected collisions, it calls either actionIfBallHitsBrick(GameObject, GameObject) or actionIfBallHitsEgo(GameObject, GameObject). Called every game loop.

Specified by:

applyGameLogic in class Playground

prepareLevel

public abstract void prepareLevel(String level)

Prepares a generic Breakout-Type level. This method relies on the methods createEgoObject(), createBall() and createBrick(int, int), among others, which are meant to be overwritten in subclasses.
Attention: the attributes ball and ego need to be set properly to GameObject instances when implementing this method prepareLevel(String).

Specified by:

prepareLevel in class Playground

Parameters:

level - String passes by the game engine (not used currently and can be ignored).
