public class LookAt
extends Pose

LookAt is a pose that always faces a target. The target is another Pose. The target is not required to be a child of this pose. The target can be anywhere in the scene graph.

This class provides several functionalities:

• It can set and get the target Pose.
• It can update its own location in space based on the target's location.
• It can serialize and deserialize itself to and from JSON format.

Method Details

getComponents

public void getComponents(List<JPanel> list)

Description copied from class: Pose

Build a Swing Component that represents this Node.

Overrides:

getComponents in class Pose

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 Pose

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 Pose

Parameters:

from - the JSON object to read from.

getTarget

public Pose getTarget()

setTarget

public void setTarget(Pose target)
