public class ShipGizmo
extends Gizmo

A ShipGizmo represents the player's ship in Multiplayer Space Invaders.

Specification Fields

• shootDifference : vector // the vector between the position and the bullet position
• shootSpeed : velocity // the speed with which the balls are shot
• maximumMovement : double // the maximum linear distance that you can move to either side
• rateOfFire : double // the number of seconds between shots
• draggedGizmos : list // the gizmos that follow this around

Constructor Detail

ShipGizmo

public ShipGizmo(Vect3 tip,
                 double depth,
                 Vect3 away,
                 double length,
                 double shootSpeed,
                 GameWorldState ws,
                 double maximumMovement,
                 double rateOfFire,
                 java.util.List<Gizmo> draggedGizmos)

Creates a ship, in the form of an arrow. The tip is at "tip", going in direction "away", with length "length", with constrant cross-sections in the xy plane.

Parameters:

tip - the location of the tip of the ship

depth - the depth of the ship

away - the vector from tip to the center of the ship

length - the length of the ship

shootSpeed - the velocity of shots fired

ws - the world state that the shots will be added to. must contain at least one player, and the first player has a score and lives counter.

maximumMovement - the maximum linear distance that you can move to either side

rateOfFire - the number of seconds between each shot

draggedGizmos - the gizmos carried by the ship

Method Detail

addDraggedGizmo

public void addDraggedGizmo(Gizmo g)

Effects:

adds g to draggedGizmos

getGuns

public java.util.List<Gun> getGuns()

Gets the list of guns that are on this ship. You can make changes to this list and they will be reflected.

increaseRateOfFire

public void increaseRateOfFire(double multiplier)

Effects:

increases the rate of fire to be multiplied by the given factor (ie if the factor is >1, it gets faster)

doActivate

public void doActivate()

Description copied from class: Gizmo

Immediately "activates" this gizmo. The definition of "activate" varies from gizmo to gizmo.

Specified by:

doActivate in class Gizmo

Effects:

attempts to shoot for the delay in user actions

doUpdate

protected void doUpdate(double dt)

Description copied from class: Gizmo

The same as GameObject.update().

Specified by:

doUpdate in class Gizmo

Effects:

calculates and sets the appropriate movement; attempts to shoot if possible

moveRightTrigger

public Trigger moveRightTrigger()

Returns:

a Trigger that moves this right

moveLeftTrigger

public Trigger moveLeftTrigger()

Returns:

a Trigger that moves this left

moveRight

public void moveRight()

Effects:

moves this right

moveLeft

public void moveLeft()

Effects:

moves this left

rotateAboutAxis

public void rotateAboutAxis(Vect3 center,
                            Vect3 axis,
                            double angle)

Description copied from class: Gizmo

Rotates this

Overrides:

rotateAboutAxis in class Gizmo

getPhysicsModel

public PhysicsModel getPhysicsModel()

Description copied from class: Gizmo

Returns the physical model of this gizmo. The model stores the structure, as well as velocity, rotation, and rotation of this gizmo.

Specified by:

getPhysicsModel in class Gizmo

Returns:

this.physicsModel

getGraphicsProperties

public GraphicsProperties getGraphicsProperties()

Description copied from class: GameObject

Returns an object that holds the information necessary for drawing this object. Making changes to this object changes the underlying object, so those changes will be reflected in the drawer.

Specified by:

getGraphicsProperties in class GameObject

Returns:

all the information needed to draw this object.

getXMLString

public java.lang.String getXMLString(java.lang.String name)

Description copied from class: GameObject

returns the XML string that would be used to save this game object

Specified by:

getXMLString in class GameObject

Returns:

String s where s is sufficient to be directly inserted into an XML file where game world information is being saved
