                                 ScaleBy

Scales a CocosNode object a zoom factor by modifying it's scale attribute.

Example:

# scales the sprite by 5x in 2 seconds
action = ScaleBy( 5, 2 )
sprite.do( action )

Methods

  start(self)
  __reversed__(self)
  __add__(self, action)
sequence operator - concatenates actions action1 + action2 -> action_result where action_result performs as: first do all that action1 would do; then perform all that action2 would do
(Inherited from cocos.actions.base_actions.Action)
  __init__(self, *args, **kwargs)
dont override - use init
(Inherited from cocos.actions.base_actions.Action)
  __mul__(self, other)
repeats ntimes the action action * n -> action_result where action result performs as: repeat n times the changes that action would do
(Inherited from cocos.actions.base_actions.IntervalAction)
  __or__(self, action)
spawn operator - runs two actions in parallel action1 | action2 -> action_result
(Inherited from cocos.actions.base_actions.Action)
  done(self)
When in the worker role, this method is reliable.
(Inherited from cocos.actions.base_actions.IntervalAction)
  init(self, scale, duration=5)
Init method.
(Inherited from cocos.actions.interval_actions.ScaleTo)
  step(self, dt)
Dont customize this method: it will not be called when in the component role for certain composite actions (like Sequence_IntervalAction).
(Inherited from cocos.actions.base_actions.IntervalAction)
  stop(self)
When the action must cease to perform this function is called by external code; after this call no other method should be called.
(Inherited from cocos.actions.base_actions.Action)
  update(self, t)
Gets called on every frame 't' is the time elapsed normalized to [0, 1] If this action takes 5 seconds to execute, t will be equal to 0 at 0 seconds.
(Inherited from cocos.actions.interval_actions.ScaleTo)

Instance Variables

  target
CocosNode object that is the target of the action
