Class FPoly

java.lang.Object

fisica.FDrawable

fisica.FBody

fisica.FPoly

public class FPoly
extends FBody

Represents a polygonal body that can be added to a world. Polygons can be created by adding vertices using the vertex method in a similar way to FPoly:

 
 FPoly myPoly = new FPoly();
 myBlob.vertex(40, 10);
 myBlob.vertex(50, 20);
 myBlob.vertex(60, 30);
 myBlob.vertex(60, 40);
 myBlob.vertex(50, 50);
 myBlob.vertex(40, 60);
 myBlob.vertex(30, 70);
 myBlob.vertex(20, 60);
 myBlob.vertex(10, 50);
 myBlob.vertex(10, 40);
 myBlob.vertex(20, 30);
 myBlob.vertex(30, 20);
 myBlob.vertex(40, 10);
 world.add(myPoly);

Constructor Detail

FPoly

public FPoly()

Constructs a polygonal body that can be added to a world. It creates an empty polygon, before adding the blob to the world use vertex to define the shape of the polygon.

Method Detail

vertex

public void vertex(float x,
                   float y)

Adds vertices to the shape of the poly. This method must called before adding the body to the world.

Parameters:

x - x coordinate of the vertex to be added

y - y coordinate of the vertex to be added

processBody

protected void processBody(org.jbox2d.dynamics.Body bd,
                           org.jbox2d.collision.shapes.ShapeDef sd)

Overrides:

processBody in class FBody

getShapeDef

protected org.jbox2d.collision.shapes.ShapeDef getShapeDef()

Overrides:

getShapeDef in class FBody

getTransformedShapeDef

protected org.jbox2d.collision.shapes.ShapeDef getTransformedShapeDef()

Overrides:

getTransformedShapeDef in class FBody

draw

public void draw(def.processing.core.PGraphics applet)

Description copied from class: FDrawable

This method is called when calling world.draw(). This method may be overriden to allow custom drawing of the object.

Overrides:

draw in class FDrawable

Parameters:

applet - the graphics onto which the object must be drawn.

drawDebug

public void drawDebug(def.processing.core.PGraphics applet)

Description copied from class: FDrawable

This method is called when calling world.drawDebug(). This method may be overriden to allow custom debug drawing of the object.

Overrides:

drawDebug in class FDrawable

Parameters:

applet - the graphics onto which the object must be drawn.
