Constructor Detail

MovingTransform3D

public MovingTransform3D()

Creates a new MovingTransform3D

MovingTransform3D

public MovingTransform3D(Transform3D v)

Creates a new MovingTransform3D, using the same values as the specified Transform3D.

Method Detail

clone

public java.lang.Object clone()

Overrides:

clone in class Transform3D

update

public void update(long elapsedTime)

Updates this Transform3D based on the specified elapsed time. The location and angles are updated.

stop

public void stop()

Stops this Transform3D. Any moving velocities are set to zero.

moveTo

public void moveTo(Vector3D destination,
                   float speed)

Sets the velocity to move to the following destination at the specified speed.

isMoving

public boolean isMoving()

Returns true if currently moving.

isMovingIgnoreY

public boolean isMovingIgnoreY()

Returns true if currently moving, ignoring the y movement.

getRemainingMoveTime

public long getRemainingMoveTime()

Gets the amount of time remaining for this movement.

getVelocity

public Vector3D getVelocity()

Gets the velocity vector. If the velocity vector is modified directly, call setVelocity() to ensure the change is recognized.

setVelocity

public void setVelocity(Vector3D v)

Sets the velocity to the specified vector.

setVelocity

public void setVelocity(Vector3D v,
                        long time)

Sets the velocity. The velocity is automatically set to zero after the specified amount of time has elapsed. If the specified time is FOREVER, then the velocity is never automatically set to zero.

addVelocity

public void addVelocity(Vector3D v)

Adds the specified velocity to the current velocity. If this MovingTransform3D is currently moving, it's time remaining is not changed. Otherwise, the time remaining is set to FOREVER.
