Detailed Description

CCActionTween.

CCActionTween is an action that lets you update any property of an object. For example, if you want to modify the "width" property of a target from 200 to 300 in 2 seconds, then:

id modifyWidth = [CCActionTween actionWithDuration:2 key:"width" from:200 to:300]; [target runAction:modifyWidth];

Another example: CCScaleTo action could be rewritten using CCPropertyAction:

scaleA and scaleB are equivalents id scaleA = [CCScaleTo actionWithDuration:2 scale:3]; id scaleB = [CCActionTween actionWithDuration:2 key:"scale" from:1 to:3];

)
static

creates an initializes the action with the property name (key), and the from and to parameters.

var create ( var  aDuration,
var  key,
var  from,
var  to 
)
static

creates an initializes the action with the property name (key), and the from and to parameters.

local create ( local  aDuration,
local  key,
local  from,
local  to 
)
static

creates an initializes the action with the property name (key), and the from and to parameters.

bool initWithDuration ( float  aDuration,
const char *  key,
float  from,

CCActionInterval* reverse ( )
virtual

returns a reversed action

Reimplemented from CCActionInterval.

var reverse ( )
virtual

returns a reversed action

Reimplemented from CCActionInterval.

local reverse ( )
virtual

returns a reversed action

Reimplemented from CCActionInterval.

void startWithTarget ( CCNode pTarget)
virtual

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

Reimplemented from CCActionInterval.

var startWithTarget ( var  pTarget)
virtual

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

Reimplemented from CCActionInterval.

local startWithTarget ( local  pTarget)
virtual

void update ( float  time)
virtual

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 CCAction.

var update ( var  time)
virtual

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 CCAction.

local update ( local  time)
virtual

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
