Class FPoly

      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

draw

public void draw(processing.core.PGraphics applet)

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

Parameters:

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

draw

public void draw(processing.core.PApplet applet)

attachImage

public void attachImage(processing.core.PImage img)

Attach an image to the object. This method allows to draw an image onto the screen instead of calling the draw(PApplet) method.

Parameters:

img - the PImage to attach to the object.

dettachImage

public void dettachImage()

Dettach any image that has been attached to the object.

See Also:

attachImage(PImage)

getImageAlpha

public float getImageAlpha()

Get the opacity with which to draw the attached image.

Returns:

the opacity, a value from 0.0 to 1.0 with which to draw the attached image

See Also:

attachImage(PImage), setImageAlpha(float)

setImageAlpha

public void setImageAlpha(float alpha)

Set the opacity with which to draw the attached image.

Parameters:

alpha - the opacity, a value from 0.0 to 1.0 with which to draw the attached image

See Also:

attachImage(PImage), getImageAlpha()

setDrawable

public void setDrawable(boolean drawable)

Set whether the object must be drawn or not.

Parameters:

drawable - if true the object will be drawn, else it will not

See Also:

isDrawable()

isDrawable

public boolean isDrawable()

Get whether the object must be drawn or not.

Returns:

drawable if true the object will be drawn, else it will not

See Also:

setDrawable(boolean)

getFillColor

public int getFillColor()

Returns the fill color of the object.

Returns:

a Processing color type. e.g. myBody.setFillColor(color(20,100,30,90));

See Also:

setNoFill(), setFill(float), setFill(float,float), setFill(float,float,float), setFill(float,float,float,float)

setFillColor

public void setFillColor(int col)

Set the fill color of the object. This method must be used in conjunction with Processing's color(). In most cases users will find it more convenient to use the versions of setFill(float), setFill(float,float), setFill(float,float,float) or setFill(float,float,float,float)

Parameters:

col - a Processing color type. e.g. myBody.setFillColor(color(20,100,30,90));

See Also:
