Transformable

public class BSPPolygon

extends TexturedPolygon3D

A BSPPolygon is a TexturedPolygon3D with a type (TYPE_FLOOR, TYPE_WALL, or TYPE_PASSABLE_WALL) an ambient light intensity value, and a BSPLine representation if the type is a TYPE_WALL or TYPE_PASSABLE_WALL.

Field Summary

static int	PASSABLE_ENTRYWAY_THRESHOLD How tall an entryway must be so that monsters/players can pass through it
static int	PASSABLE_WALL_THRESHOLD How short a wall must be so that monsters/players can step over it.
static int	TYPE_FLOOR
static int	TYPE_PASSABLE_WALL
static int	TYPE_WALL

Constructor Summary

BSPPolygon(Vector3D[] vertices, int type)
Creates a new BSPPolygon with the specified vertices and type (TYPE_FLOOR, TYPE_WALL, or TYPE_PASSABLE_WALL).

Method Summary

BSPPolygon	clone(Vector3D[] vertices) Clone this polygon, but with a different set of vertices.
float	getAmbientLightIntensity()
BSPLine	getLine() Gets the line representing the BSPPolygon.
boolean	isSolidWall() Returns true if the BSPPolygon is a solid wall (not passable).
boolean	isWall() Returns true if the BSPPolygon is a wall.
void	setAmbientLightIntensity(float a)

Constructor Detail

BSPPolygon

public BSPPolygon(Vector3D[] vertices,
                  int type)

Creates a new BSPPolygon with the specified vertices and type (TYPE_FLOOR, TYPE_WALL, or TYPE_PASSABLE_WALL).

Method Detail

clone

public BSPPolygon clone(Vector3D[] vertices)

Clone this polygon, but with a different set of vertices.

isWall

public boolean isWall()

Returns true if the BSPPolygon is a wall.

isSolidWall

public boolean isSolidWall()

Returns true if the BSPPolygon is a solid wall (not passable).

getLine

public BSPLine getLine()

Gets the line representing the BSPPolygon. Returns null if this BSPPolygon is not a wall.

setAmbientLightIntensity

public void setAmbientLightIntensity(float a)

getAmbientLightIntensity

public float getAmbientLightIntensity()
