Constructor Detail

GameEntity

public GameEntity(GameEngine ge,
                  java.lang.String file,
                  int x,
                  int y,
                  ScreenManager sm)

This is the constructor of our abstract class GameEntity. All objects in the screen are instance of this class.

Parameters:

ge - GameEngine object to send specific messages on specific occurrences.

file - Path to the image.

x - X position of the object.

y - Y position of the object.

sm - ScreenManager object to determine the boundaries of the screen.

Method Detail

getX

public int getX()

Returns:

The x position of the entity.

getY

public int getY()

Returns:

The y position of the entity.

move

public void move(long delta)

Moves the entity. Probably will be overridden by each object.

Parameters:

delta - is the amount of time that entity will move.

draw

public void draw(java.awt.Graphics2D g)

This method draws the visual of the entity to the screen. Each object draws itself.

This method check the collision between itself and another entity. GameEngine calls this method for each entity and they return a boolean value if collision occurs.

Parameters:

entity - Entity to be collided.
