Constructor Detail

FGearJoint

public FGearJoint(FJoint joint1,
                  FJoint joint2)

Construct a gear joint between two joints.

Parameters:

joint1 - first joint of the gear

joint2 - second joint of the gear

Method Detail

setRatio

public void setRatio(float ratio)

Sets the ratio of movement transfer from one joint to the other of the gear.

Parameters:

ratio - the ratio of movement that is transfered between the first and the second joints of the gear

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:

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

setNoFill

public void setNoFill()

Set that the object must be drawn without fill.
