static

creates the action with the same scale factor for X and Y

static ScaleTo* create ( float  duration,
float  sx,
float  sy 
)
static

creates the action with and X factor and a Y factor

static ScaleTo* create ( float  duration,
float  sx,
float  sy,
float  sz 
)
static

creates the action with X Y Z factor

bool initWithDuration ( float  duration,
float  s 
)
protected

initializes the action with the same scale factor for X and Y

bool initWithDuration ( float  duration,
float  sx,
float  sy 
)
protected

bool initWithDuration ( float  duration,
float  sx,
float  sy,
float  sz 
)
protected

initializes the action with X Y Z factor

virtual ScaleTo* reverse ( void  ) const
overridevirtual

returns a new action that performs the exactly the reverse action

Implements ActionInterval.

Reimplemented in ScaleBy.

virtual void startWithTarget ( Node target)
overridevirtual

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

Reimplemented from ActionInterval.

Reimplemented in ScaleBy.

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.
