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

Reimplemented from ActionInterval.

Reimplemented in FadeOut, and FadeIn.

static FadeTo* create ( float  duration,
GLubyte  opacity 
)
static

creates an action with duration and opacity

virtual FadeTo* reverse ( void  ) const
overridevirtual

returns a new action that performs the exactly the reverse action

Reimplemented from ActionInterval.

Reimplemented in FadeOut, and FadeIn.

virtual void startWithTarget ( Node target)
overridevirtual

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

Reimplemented from ActionInterval.

Reimplemented in FadeOut, and FadeIn.

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
