Constructor Detail

FLine

public FLine(float x1,
             float y1,
             float x2,
             float y2)

Constructs a line body that can be added to a world.

Parameters:

x1 - horizontal position of the first point of the line

y1 - vertical position of the first point of the line

x2 - horizontal position of the second point of the line

y2 - vertical position of the second point of the line

Method Detail

setStart

public void setStart(float x,
                     float y)

Sets the start point of the line. Under the hood the body is removed and readded to the world.

Parameters:

x - horizontal position of the first point of the line

y - vertical position of the first point of the line

setEnd

public void setEnd(float x,
                   float y)

Sets the end point of the line. Under the hood the body is removed and readded to the world.

Parameters:

x - horizontal position of the first point of the line

y - vertical position of the first point of the line

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));
