getTransform

public Transform2D getTransform()

Convenience method to retrieve the translation and rotation in a new transform.

getTransform

public Transform2D getTransform(Transform2D result)

Convenience method to retrieve the translation and rotation in a transform.

Returns:

a reference to the result transform, for chaining.

getTranslation

public Vector2f getTranslation()

Returns the translation of this logic for the purpose of spawning actors, etc.

getRotation

public float getRotation()

Returns the rotation of this logic for the purpose of spawning actors, etc.

getShape

public Shape getShape()

Returns a reference to this logic's shape, or returns null for none.

getPatrolPath

public Vector2f[] getPatrolPath()

Returns a patrol path for this logic.

addShapeObserver

public void addShapeObserver(Logic.ShapeObserver observer)

Adds an observer for changes to the logic's shape.

removeShapeObserver

public void removeShapeObserver(Logic.ShapeObserver observer)

Removes a shape observer.

getModel

public ConfigReference<ModelConfig> getModel()

Returns a reference to the model associated with this logic, if any.

signal

public void signal(int timestamp,
                   Logic source,
                   String name)

Sends a generic "signal" to the logic.

Parameters:

timestamp - the signal timestamp.

source - the source of the signal.

setVariable

public void setVariable(int timestamp,
                        Logic source,
                        String name,
                        Object value)

Sets the value of a variable.

Parameters:

timestamp - the set timestamp.

source - the source of the request.

getVariable

public Object getVariable(String name)

Retrieves the value of a variable (or null if unset).
