Detailed Description

Moves a Node object x,y pixels by modifying it's position attribute.

x and y are relative to the position of the object. Several MoveBy actions can be concurrently called, and the resulting movement will be the sum of individual movements.

Member Function Documentation

virtual MoveBy* clone ( ) const
overridevirtual

returns a clone of action

Implements ActionInterval.

Reimplemented in MoveTo.

static MoveBy* create ( float  duration,
const Point deltaPosition 
)
static

creates the action

bool initWithDuration ( float  duration,
const Point deltaPosition 
)

initializes the action

virtual MoveBy* reverse ( void  ) const
overridevirtual

returns a new action that performs the exactly the reverse action

Implements ActionInterval.

virtual void startWithTarget ( Node target)
overridevirtual

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

Reimplemented from ActionInterval.

Reimplemented in MoveTo.

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.
