Detailed Description

An action that moves the target with a cubic Bezier curve by a certain distance.

Member Function Documentation

create()

static BezierBy* create ( float  t, const ccBezierConfig &  c  )

static

Creates the action with a duration and a bezier configuration.

Parameters

t	Duration time, in seconds.
c	Bezier config.

Returns

An autoreleased BezierBy object.

When this function bound to js or lua,the input params are changed.
in js: var create(var t,var table)
in lua: local create(local t, local table)

clone()

virtual BezierBy* clone ( ) const

overridevirtual

Returns a clone of action.

Returns

A clone action.

Reimplemented from ActionInterval.

Reimplemented in BezierTo.

reverse()

virtual BezierBy* reverse ( ) const

overridevirtual

Returns a new action that performs the exact reverse of the action.

Returns

A new action that performs the exact reverse of the action. @js NA

Reimplemented from ActionInterval.

Reimplemented in BezierTo.

startWithTarget()

virtual void startWithTarget ( Node *  target )

overridevirtual

Called before the action start.

It will also set the target.

Parameters

target

A certain target.

Reimplemented from ActionInterval.

update()

virtual void update ( float  time )

overridevirtual

Parameters

time	In seconds.

Reimplemented from Action.

initWithDuration()

bool initWithDuration ( float  t, const ccBezierConfig &  c  )

protected

initializes the action with a duration and a bezier configuration

Parameters

t	in seconds
