Constructor Summary

CollisionFinder()
Creates a new CollisionFinder object

Method Summary

boolean	collided(AbstractGameObject go1, AbstractGameObject go2) This method checks, if a collision between the two specified game objects has occured.
boolean	collided(AbstractMesh mesh1, AbstractMesh mesh2) This method checks, if a collision between the two specified meshes has occured.
java.util.ArrayList<Triangle>	collided(AbstractMesh mesh, Terrain terrain) This method checks, if a collision between the bottom center point of the mesh and the terrain has occured and returns the triangle(s) that has/have collided with the mesh.
boolean	collided(Point3D point, AbstractGameObject go) This method checks for collision between the specified point and the game object
boolean	collided(Point3D point, AbstractMesh mesh) This method checks for collision between the specified point and the mesh
java.util.ArrayList<Triangle>	collided(Point3D point, Terrain terrain) This method checks, if a collision between a point and the terrain has occured.

Method Detail

collided

public boolean collided(AbstractMesh mesh1,
                        AbstractMesh mesh2)

This method checks, if a collision between the two specified meshes has occured.

Parameters:

mesh1 - first mesh

mesh2 - second mesh

Returns:

collision detected? --> true=yes, false=no

collided

public boolean collided(AbstractGameObject go1,
                        AbstractGameObject go2)

This method checks, if a collision between the two specified game objects has occured. This method is pretty similar to the one that checks two meshes for collision. The only difference between them is that you can specify game object instead of directly specifying mesh objects.

Parameters:

go1 - first game object

go2 - second game objet

Returns:

collision detected? --> true=yes, false=no

collided

public boolean collided(Point3D point,
                        AbstractMesh mesh)

This method checks for collision between the specified point and the mesh

Parameters:

point - point to check for collision with mesh

mesh - mesh to check for collision with point

Returns:

collision detected? --> true=yes, false=no

collided

public boolean collided(Point3D point,
                        AbstractGameObject go)

This method checks for collision between the specified point and the game object

Parameters:

point - point to check for collision with game object

go - game object to check for collision with point

Returns:

collision detected? --> true=yes, false=no

collided

public java.util.ArrayList<Triangle> collided(AbstractMesh mesh,
                                              Terrain terrain)

This method checks, if a collision between the bottom center point of the mesh and the terrain has occured and returns the triangle(s) that has/have collided with the mesh.

Parameters:

mesh - mesh, that could have been collided with the terrain

terrain - terrain to check collision with

Returns:

ArrayList with the triangles, that have collided with the bottom center point of the specified mesh

collided

public java.util.ArrayList<Triangle> collided(Point3D point,
                                              Terrain terrain)

This method checks, if a collision between a point and the terrain has occured. To be precisely, it finds the trangle(s) this point is located on and returns the involved triangle(s).

Parameters:

point - point to check collision with

terrain - terrain to check collision with

Returns:

triangle(s) the specified point is located on
