com.marginallyclever.ro3.node.nodes.HingeJoint

public class HingeJoint
extends Node

a HingeJoint is a joint that can rotate around the local Z axis.

a HingeJoint should be attached to a child Pose referenced as the axle. In this way the axle's parent Pose can be thought of as the initial pose. This helps prevent drift over time.

Method Details

getComponents

public void getComponents(List<JPanel> list)

Description copied from class: Node

Build a Swing Component that represents this Node.

Overrides:

getComponents in class Node

Parameters:

list - the list to add components to.

update

public void update(double dt)

Description copied from class: Node

Called every frame.

Overrides:

update in class Node

Parameters:

dt - the time since the last frame.

toJSON

public org.json.JSONObject toJSON()

Description copied from class: Node

Serialize this node and its children to a JSON object and its children. Classes that override this method should call super.toJSON() first, then add to the object returned.

Overrides:

toJSON in class Node

Returns:

the JSON object.

fromJSON

public void fromJSON(org.json.JSONObject from)

Description copied from class: Node

Deserialize this node and its children from a JSON object and its children. Classes that override this method should call super.fromJSON(). When they do it will trigger the creation of child nodes. The child nodes will then call their own fromJSON() methods.

Overrides:

fromJSON in class Node

Parameters:

from - the JSON object to read from.

getAngle

public double getAngle()

setAngle

public void setAngle(double degrees)

getMinAngle

public double getMinAngle()

setMinAngle

public void setMinAngle(double v)

getMaxAngle

public double getMaxAngle()

setMaxAngle

public void setMaxAngle(double v)

getVelocity

public double getVelocity()

setVelocity

public void setVelocity(double velocity)

getAcceleration

public double getAcceleration()

setAcceleration

public void setAcceleration(double acceleration)

getAxle

public Pose getAxle()

setAxle

public void setAxle(Pose subject)

getIcon

public Icon getIcon()

Description copied from class: Node

Set a custom icon for this node.

Overrides:

getIcon in class Node

Returns:

the icon, or null if none.
