Method Detail

getClone

public TetrisGameState getClone()

Create a cloned copy of the current object and return it. In general the created copy will be a deep copy of the provided instance. As a result this operation an be quite expensive if used incorrectly.

Specified by:

getClone in interface Cloneable

Overrides:

getClone in class GridGameState

Returns:

An exact clone of the current object instance.

See Also:

Object.clone()

createNewShape

public void createNewShape()

Create a new random Tetris shape at the top of the grid

setItem

public void setItem(int i,
                    int j,
                    GameItem item)

Description copied from class: GridGameState

Set an item at a specific index in the matrix

Overrides:

setItem in class GridGameState

Parameters:

i - the specified Column

j - the specified Row

item - the item to set. This method does not check if an item already exists, and will simply override what is in that position.

mergeCurrentShape

public void mergeCurrentShape()

Merge the current AbstractShape into the grid

calculateScore

public void calculateScore(int rowsCleared)

Calculate the score based on the amount of rows cleared

Parameters:

rowsCleared -

getErodedShapeCount

public int getErodedShapeCount()

Get the number of blocks form the current AbstractShape that will be removed if the shape was to be merged at its current position

Returns:

the number of eroded blocks

getEmptyCellsBeforeOccupied

public int getEmptyCellsBeforeOccupied(int x,
                                       int startY)

Get the number of empty cells in the grid before an occupied one

Parameters:

x - the row to look in

startY - the column to start looking at

Returns:

the number of empty cells

clearFullRows

public static int clearFullRows(GameItem[][] state,
                                int Width,
                                int Height)

Clear all full rows for a given game grid

Parameters:

state - the grid of blocks

Width - the with of the grid

Height - the heigth of the grid

Returns:

the amount of rows cleared.

clearFullRows

public int clearFullRows()

Clear any full rows in the current game grid.

Returns:

setShapeLeftGrid

public boolean setShapeLeftGrid()

Set the current AbstractShape as far to the left of the current grid as it can go

FitShapeInGridTopDown

public boolean FitShapeInGridTopDown()

Fit the current shape in the current grid from its current position moving down untill it either collides or is at the bottowm of the grid

Returns:

moveRight

public boolean moveRight()

Move the current piece one position to the right if it doesn't collide there.

Returns:

currentShapeCollides

public boolean currentShapeCollides()

Check whether one of the blocks in the current shape of the game collides in the grid

Returns:

A boolean that indicates if a collision occurred

collides

public boolean collides(AbstractShape shape)

Check whether one of the blocks in the AbstractShape collides in the current grid

Parameters:

blocks - The given AbstractShape

Returns:

A boolean that indicates if a collision occurred

collides

public boolean collides(List<TetrisBlock> blocks)

Check whether one of the blocks in the list collides in the current grid

Parameters:
