public class Point2D

extends java.lang.Object

This class is used to represent a location or vector in screenspace. Although the structure holds two floats, you will generally call the getInt functions to get the integers because screenspace is in pixels. A Point2D can be translated into a Point3D with z = 0.

Field Summary

float	x X-axis value or length.
float	y Y-axis value or length.

Constructor Summary

Point2D()
Constructs a Point2D at the orgin.

Point2D(float X, float Y)
Constructs a Point2D at the given point.

Point2D(Point2D p)
Constructs a Point2D at the given point.

Method Summary

int	getIntx() This method is a shortcut to Math.round(x) which returns an integer.
int	getInty() This method is a shortcut to Math.round(y) which returns an integer.
double	getLength() Returns the distance from the point to the orgin.
Point2D	getProduct(float scalar) Returns a new Point2D that is the scalar product of this one.
Point2D	getSum(Point2D p) Returns a new Point2D that is the sum of this one, and the given vector.
