Class Port

java.lang.Object
  Port

public class Port

extends java.lang.Object

Class Port implements a gate. FIXME: (1.1) This should probably be named "Gate".

A gate consists of two buoys floating on the water, left (portboard) and right (starboard).

Contains the anchored positions for each buoy and the moving positions of each buoy. The buoys can move, e.g. when hit by a boat. A buoy that has moved will float back to its anchored position.

Port contains the functionality to test collisions with the players and to test passing the gate. Passing the gate is dependent on the direction.

Method Summary

void	crashWithPlayer(Player p) Checks the collisions between a player and the gate buoys.
void	move(float seconds) Moves the buoys towards the anchoring position if they aren't there.
boolean	passed(Vector2 p1, Vector2 p2) Checks if the line segment p1-p2 (the interval traveled by the boat) intersects with this gate while going to the allowed direction.

Constructor Detail

Port

public Port(Vector2 l,
            Vector2 r)

Constructor. FIXME: (1.1) Use p and s (portboard/starboard)

Parameters:

l - position of the portboard buoy

r - position of the starboard buoy

Method Detail

move

public void move(float seconds)

Moves the buoys towards the anchoring position if they aren't there.

Parameters:

seconds - time slice according to which the buoys should be moved

crashWithPlayer

public void crashWithPlayer(Player p)

Checks the collisions between a player and the gate buoys.

If there is a collision, the buoy should be moved.

Parameters:

p - the player to check the collisions with

passed

public boolean passed(Vector2 p1,
                      Vector2 p2)

Checks if the line segment p1-p2 (the interval traveled by the boat) intersects with this gate while going to the allowed direction.

Returns:

true if intersects correctly, false if doesn't
