virtual void startWithTarget ( Node target)
overridevirtual

called before the action start. It will also set the target.

Reimplemented from ActionInterval.

Reimplemented in JumpTo.

virtual void update ( float  time)
overridevirtual

called once per frame.

time a value between 0 and 1

For example:

  • 0 means that the action just started
  • 0.5 means that the action is in the middle
  • 1 means that the action is over

Reimplemented from Action.
