init(). Method in class NightHunter: Game initialization method - starts the MediaTracker (needed to make sure images are completely loaded), load game background the mouse - gun images, and load audio clips.
initResources(Applet, MediaTracker, int). Static method in class Eyes: Initialize Resources - get bitmap images and synchronize with the Media Tracker.
isPointInside(Point). Method in class Sprite: See if a point is inside the Sprite bounding box limits.
isPointInside(Point). Method in class SpriteVector: Returns a Sprite if the point lies within a Sprite.
isPointInside(Point). Method in class SRVector: This method is necessary to determine when and "Eye" class has been clicked by the mouse otherwise because of the z-ordering of bitmap images the "gun" image would always be returned.
