Specified by:

getLastLocation in interface SwitchableMovement

Returns:

the last location

setLocation

public void setLocation(Coord lastWaypoint)

Description copied from interface: SwitchableMovement

Tell the movement model what its current location is

Specified by:

setLocation in interface SwitchableMovement

isReady

public boolean isReady()

Description copied from interface: SwitchableMovement

Checks if the movement model is finished doing its task and it's time to switch to the next movement model. The method should be called between getPath() calls.
