Class ColliderPolygon

java.lang.Object
  edu.eside.flingbox.physics.collisions.Collider
      edu.eside.flingbox.physics.collisions.ColliderPolygon

All Implemented Interfaces:

PhysicBody.OnMovementListener, PositionComparator.Positionable

public class ColliderPolygon
extends Collider
implements PhysicBody.OnMovementListener

Collider for a polygon. it handles all functions needed by Collision system NOTE This class should only be created by PhisicPolygon. How collision detector optimizer works: - When created collider check each polygon's vertex angle and stores them. - When bounding circle collides Collider checks only segments in other circle region.

Constructor Detail

ColliderPolygon

public ColliderPolygon(Vector2D[] contour,
                       PhysicBody thisPhysic)

Default constructor for a polygon collider.

Parameters:

contour - Polygon's points. It handles pointer in order to preserve recurses, so mPolygonContour should be automatically rotated. NOTE It has to be in counterclockwise ordering!!!

Method Detail

checkContacts

public Contact[] checkContacts(Collider collider)

Description copied from class: Collider

Checks if objects can collide

Specified by:

checkContacts in class Collider

Parameters:

collider - other objects collider.

Returns:

true if objects can collide
