Detailed Description

Rotates a Node object to a certain angle by modifying it's rotation attribute.

The direction will be decided by the shortest angle.

Member Function Documentation

virtual RotateTo* clone ( ) const
overridevirtual

returns a clone of action

Implements ActionInterval.

static RotateTo* create ( float  duration,
float  deltaAngleX,
float  deltaAngleY 
)
static

creates the action with separate rotation angles

static RotateTo* create ( float  duration,
float  deltaAngle 
)
static

creates the action

bool initWithDuration ( float  duration,
float  deltaAngle 
)
protected

initializes the action

bool initWithDuration ( float  duration,
float  deltaAngleX,
float  deltaAngleY 
)
protected
virtual RotateTo* reverse ( ) 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.

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.
