Constructor Detail

FallingDown

public FallingDown(GameObject target,
                   java.util.List directions,
                   int interval,
                   boolean jumping,
                   GameObject scroller)

Make someone or something start moving.

Parameters:

target - object to be moved

directions - a list of directions to move. the last one keeps going until you hit something.

interval - how long between steps (millis)

Method Detail

getTarget

public GameObject getTarget()

Returns the target we're moving.

getDirections

public java.util.List getDirections()

Returns the list of directions to move.

setDirections

public void setDirections(java.util.List dirs)

Reset the list of directions.

getInterval

public int getInterval()

Returns the speed at which we're falling or moving.

setInterval

public void setInterval(int interval)

Sets the speed at which we're moving.

start

public void start()

Starts them moving in the desired direction.

stop

public void stop()

Stop falling.

timerExpired

public void timerExpired()

Time to move them.

Specified by:

timerExpired in interface Timed

advance

protected boolean advance()

Advance them in the default direction

Returns:

true if we should continue moving, false otherwise

keepFalling

public boolean keepFalling(GameObject obj)

Checks whether or not the target should keep falling

doesSupport

public boolean doesSupport(int x,
                           int y,
                           GameObject me,
                           boolean inanimate)

Returns true if the selected square has the properties "blocking" or "ladder", meaning that it can support a character's weight. Ignores a particular object. Use this when the agent is actually IN location (x,y), but we need to check anyway.

Parameters:

x - map x location to check

y - map y location to check

me - ignore this object if it's in the list.

inanimate - whether it's a critter or not (false if critter)

toString

public java.lang.String toString()

Returns debugging string.

Overrides:

toString in class MapObject

Returns:

a short String describing this object. If the object represents a group of items, such as coins, the returned description will be a modified version of the description that includes quantity information.
