Method Detail

setupImages

protected void setupImages()

Description copied from class: Spaceship

Sort-of abstract method available for overriddance [sic]. Subclasses can implement this to set their sprite (back) to its default value. It's called whenever a reset to the default sprite is needed, e. g. after the blinking animation.

Overrides:

setupImages in class Spaceship

See Also:

Spaceship.doBlink()

setupKeys

protected void setupKeys()

Set keys according to the side we're on.

setSide

public void setSide(int the_side)

Overrides:

setSide in class Spaceship

getSide

public int getSide()

Overrides:

getSide in class Spaceship

setMayMoveUpAndDown

public void setMayMoveUpAndDown(boolean may)

getMayMoveUpAndDown

public boolean getMayMoveUpAndDown()

act

public void act()

Do quantum object duties, then check what the player wants the spaceship to do.

Overrides:

act in class Spaceship

moveLeft

public void moveLeft()

moveRight

public void moveRight()

moveUp

public void moveUp()

moveDown

public void moveDown()

updateHealth

public void updateHealth()

Update the health bar in InvadersWorld.

See Also:

InvadersWorld.setHealthBar(int side, int value)

addHitpoints

public void addHitpoints(int n_hitpoints)

Overrides:

addHitpoints in class Spaceship

removeHitpoints

public void removeHitpoints(int n_hitpoints)

Overrides:

removeHitpoints in class Spaceship

setHitpoints

public void setHitpoints(int n_hitpoints)

Overrides:

setHitpoints in class Spaceship

beforeDestruction

public void beforeDestruction()

Before destruction: tell world to announce the winner (which is the other side, if this is destroyed).

Overrides:

beforeDestruction in class Spaceship

hit

public boolean hit(AIControlledSpaceship s)

Description copied from class: QuantumObject

hit. Base method hit(Actor). Uses java.lang.reflect to dynamically find out which hit() method of the quantum object to invoke based on which actual class "actor" has. Dynamic dispatch comes true!

Overrides:

hit in class QuantumObject

Parameters:

s - The object we are interacting with

Returns:

boolean. True if this quantum object should survive, false otherwise.
