All Implemented Interfaces:

java.io.Serializable, SimState

public class Rectangle
extends Geom

A 2D geometry primative of a rectangle. The rectangle can be placed within the X-Y plane. The height of the shape in the Z dir is assumed to be infinite. The rectangle is compatible with 3D spaces. Currently incomplete, this does not handle anything to do with collisions or living in a space, jsut a placeholder currently

Method Summary

Rectangle	cloneState(ClonedReferences util) deep clones the state object, any references to other SimState objects should be cloned and assigned to the clone via the ClonedReferences util object.
void	computeAABB() compute the AABB for this object and put it in aabb.
float	getHeight()
void	getVetex(int vertex, float[] coordPassback) vertices numbered clockwise vertex 0 is the top left (posative height, negative width) vertex 1 is the top right (posative height, posative width) vertex 2 is the bottom right (negative height, posative width) vertex 3 is the bottom left (negative height, negative width) returns the absolute x, y coords of that vertex in the passback.
void	getVetex(int vertex, Vector2 coordPassback) vertices numbered clockwise vertex 0 is the top left (posative height, negative width) vertex 1 is the top right (posative height, posative width) vertex 2 is the bottom right (negative height, posative width) vertex 3 is the bottom left (negative height, negative width) returns the absolute x, y coords of that vertex in the passback.
float	getWidth()
float	pointDepth(float x, float y, float z) returns the penetration depth (smallest possible) can be negative, indicating the smallest distance to the point

Method Detail

computeAABB

public void computeAABB()

Description copied from class: Geom

compute the AABB for this object and put it in aabb. this function always performs a fresh computation, it does not inspect the GEOM_AABB_BAD flag.

Specified by:

computeAABB in class Geom

getVetex

public void getVetex(int vertex,
                     float[] coordPassback)

vertices numbered clockwise vertex 0 is the top left (posative height, negative width) vertex 1 is the top right (posative height, posative width) vertex 2 is the bottom right (negative height, posative width) vertex 3 is the bottom left (negative height, negative width) returns the absolute x, y coords of that vertex in the passback.

Parameters:

vertex -

coordPassback -

getVetex

public void getVetex(int vertex,
                     Vector2 coordPassback)

vertices numbered clockwise vertex 0 is the top left (posative height, negative width) vertex 1 is the top right (posative height, posative width) vertex 2 is the bottom right (negative height, posative width) vertex 3 is the bottom left (negative height, negative width) returns the absolute x, y coords of that vertex in the passback.

Parameters:

vertex -

coordPassback -

getWidth

public float getWidth()

setWidth

public void setWidth(float width)

getHeight

public float getHeight()

setHeight

public void setHeight(float height)

pointDepth

public float pointDepth(float x,
                        float y,
                        float z)

returns the penetration depth (smallest possible) can be negative, indicating the smallest distance to the point

Parameters:

x -

y -

z -

Returns:

cloneState

public Rectangle cloneState(ClonedReferences util)

Description copied from interface: SimState

deep clones the state object, any references to other SimState objects should be cloned and assigned to the clone via the ClonedReferences util object. The util object ensures that multiple clones of the same object are not performed during a clone operation.

Parameters:

util - instanciate a new one if top level cloning
