- All Implemented Interfaces:
- Sprite
public class ProjectileSprite
- extends ShapeSprite
This class encapsulates an on-screen sprite that represents a projectile in
our game.
A projectile is either live or dead. Only live projectiles are shown
on-screen. It has a linear trajectory that is represented by an x and y
displacement per frame. The projectile has a finite lifespan, defined in
terms of a number of frames. As the projectile finishes its lifespan, its
sprite grows progressively smaller until it disappears.

ProjectileSprite
public ProjectileSprite(java.awt.Dimension dimensionOfDrawingRegion,
java.awt.Point shooterTip,
int xDisplacement,
int yDisplacement)
- Constructs a projectile sprite located at the specified position. The
sprite will move with the specified xDisplacement and yDisplacement
values.
- Parameters:
dimensionOfDrawingRegion
-
moveAlongTrajectory
public void moveAlongTrajectory()
- Cause this projectile to move one step along its defined trajectory. If
the trajectory travels off the screen, the projecile dies.
- Overrides:
