Method Detail

init

public void init(Pathable pable,
                 long tickstamp)

Description copied from interface: Path

Called once to let the path prepare itself for the process of animating the supplied pathable. Path users should also call Path.tick(com.threerings.media.util.Pathable, long) after Path.init(com.threerings.media.util.Pathable, long) with the same initialization timestamp.

Specified by:

init in interface Path

Overrides:

init in class BobblePath

tick

public boolean tick(Pathable pable,
                    long tickStamp)

Description copied from interface: Path

Called to request that this path update the position of the specified pathable based on the supplied timestamp information. A path should record its initial timestamp and determine the progress of the pathable along the path based on the time elapsed since the pathable began down the path.

Specified by:

tick in interface Path

Overrides:

tick in class BobblePath

Parameters:

pable - the pathable whose position should be updated.

tickStamp - the timestamp associated with this frame.

Returns:

true if the pathable's position was updated, false if the path determined that the pathable should not move at this time.
