Example usage for Java com.badlogic.gdx.math Polygon fields, constructors, methods, implement or subclass

Introduction

In this page you can find the methods, fields and constructors for com.badlogic.gdx.math Polygon.

The text is from its open source code.

Field

boolean	dirty

Constructor

	Polygon() Constructs a new polygon with no vertices.
	Polygon(float[] vertices) Constructs a new polygon from a float array of parts of vertex points.

Method

float	area() Returns the area contained within the polygon.
boolean	contains(float x, float y) Returns whether an x, y pair is contained within the polygon.
Rectangle	getBoundingRectangle() Returns an axis-aligned bounding box of this polygon.
float	getScaleX() Returns the total horizontal scaling applied to the polygon.
float	getScaleY() Returns the total vertical scaling applied to the polygon.
float[]	getTransformedVertices() Calculates and returns the vertices of the polygon after scaling, rotation, and positional translations have been applied, as they are position within the world.
float[]	getVertices() Returns the polygon's local vertices without scaling or rotation and without being offset by the polygon position.
float	getX() Returns the x-coordinate of the polygon's position within the world.
float	getY() Returns the y-coordinate of the polygon's position within the world.
void	setOrigin(float originX, float originY) Sets the origin point to which all of the polygon's local vertices are relative to.
void	setPosition(float x, float y) Sets the polygon's position within the world.
void	setRotation(float degrees) Sets the polygon to be rotated by the supplied degrees.
void	setScale(float scaleX, float scaleY) Sets the amount of scaling to be applied to the polygon.
void	setVertices(float[] vertices) Sets the polygon's local vertices relative to the origin point, without any scaling, rotating or translations being applied.
void	translate(float x, float y) Translates the polygon's position by the specified horizontal and vertical amounts.
