void	onSpace(KeyEvent e, GameObject ego)	calls superclass EgoController.onSpace(KeyEvent, GameObject) only, if the time elapsed since last pressing of space is above 0.1 ms.
void	restoreDynamicState()	Restores formally saved values of x,y position and speed vx,vy from attributes back to the ego object.
void	saveDynamicState()	Copies current values of x,y position and speed vx,vy into attributes.
boolean	stopObject()	extends parent class implementation by a check whether or not the ego object collides with any other "obstacle" object.

Constructor Details

CollisionAwareEgoController

public CollisionAwareEgoController(double egoRad)

Parameters:

egoRad - radius of ego object to be used.

CollisionAwareEgoController

public CollisionAwareEgoController(double egoRad,
 File soundOnShot)

Parameters:

egoRad - radius of ego object to be used.

soundOnShot - WAV file to be played on shot

Method Details

saveDynamicState

public void saveDynamicState()

Copies current values of x,y position and speed vx,vy into attributes. These can be restored by call to restoreDynamicState().

restoreDynamicState

public void restoreDynamicState()

Restores formally saved values of x,y position and speed vx,vy from attributes back to the ego object. These values should have been stored before by a call to saveDynamicState(), otherwise all values will be 0.00.

stopObject

public boolean stopObject()

extends parent class implementation by a check whether or not the ego object collides with any other "obstacle" object. If yes, the position stays fixed (by using saveDynamicState() and restoreDynamicState().

Overrides:

stopObject in class EgoController

Returns:

true if the object reached the boundaries of the level, false otherwise.

onSpace

public void onSpace(KeyEvent e,
 GameObject ego)

calls superclass EgoController.onSpace(KeyEvent, GameObject) only, if the time elapsed since last pressing of space is above 0.1 ms.

Overrides:

onSpace in class EgoController

Parameters:

e - KeyEvent of the space key

ego - EgoObject instance (used to determine position of shot object's start)
