Detailed Description

Fades an object that implements the RGBAProtocol protocol.

It modifies the opacity from the current value to a custom one.

Warning

This action doesn't support "reverse"

Member Function Documentation

virtual FadeTo* clone ( ) const

overridevirtual

returns a clone of action

Implements ActionInterval.

static FadeTo* create ( float  duration, GLubyte  opacity  )

static

creates an action with duration and opacity

bool initWithDuration	(	float	duration,
		GLubyte	opacity
	)

initializes the action with duration and opacity

virtual FadeTo* 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.

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.
