Method Detail

initialize

public void initialize()

Sets initial properties.

Specified by:

initialize in interface GameObject

Overrides:

initialize in class MapObject

setMap

public void setMap(GameMap map,
                   int x,
                   int y)

We've been put in a map. Start the timer.

Specified by:

setMap in interface GameObject

Overrides:

setMap in class MapObject

start

public void start()

Start it up

stop

public void stop()

Stop it

timerExpired

public void timerExpired()

Time to move.

Specified by:

timerExpired in interface Timed

move

public GameObject move()

Move a square forward. If blocked, return the blocking object.

canGoUp

public boolean canGoUp(GameMap map,
                       Point p)

Can we move up? Up is a problematic direction that requires special handling. We have to check whether the objects above us can be pushed upwards.

Parameters:

map - the map

p - starting point (our reference location: left side)

moveOccupants

public void moveOccupants(Point p,
                          Point dir)

Move anyone sitting on top, too. But this won't prevent us from moving, even if they don't.

Parameters:

dir - the direction we moved

getBlocker

public GameObject getBlocker(GameMap map,
                             int x,
                             int y)

Find any blocking object in this location

Parameters:

map - the map

x - x-loc

y - y-loc

getBlocker

public GameObject getBlocker(GameMap map,
                             Point p)

Find any blocking object in this location

Parameters:

map - the map

p - map location

makeLocalCopy

public java.util.List makeLocalCopy(java.util.List orig)

Make a local copy of a list. Necessary because getObjectsAt returns the REAL list, so any changes made will change it. We don't need that headache.

bounce

public void bounce()

Change to a different direction.

destroy

public void destroy()

Destroys the object.

Specified by:

destroy in interface GameObject

Overrides:

destroy in class MapObject
