Cocos2d-x study notes (11.8) DelayTime ReverseTime TargetedAction ActionFloat Blink

1. DelayTime

When setting the create method create (float d) long, update operations without any method. It may be a delay between the operation.

2. ReverseTime

create methods create (FiniteTimeAction * action) to set binding action. (- time 1), the effect of the progress of the progress of the normal rewind rewind achieve _other-> update upadte process execution.

3. TargetedAction

By create (Node * target, FiniteTimeAction * action) and node method action binding. When runAction, actually performing node bound binding action.

4. ActionFloat

From FROM to a value according to the progress taken as a value, passed to the callback function.

create (float duration, float from, float to, ActionFloatCallback callback) the parameters assigned to the variable.

startWithTarget in, _delta is to-from.

update method:

float value = _to - _delta * (1 - t); // from + t * delta

    if (_callback)
    {
        // report back value to caller
        _callback(value);
    }

5. Blink

flicker. create (float duration, int blinks) disposed interval and number of flashes.

startWithTarget, get Visibility:

_originalState = target->isVisible();

update：

IF (_target &&! isDone ()) 
    { 
        a float Slice = 1.0f / _times; // a proportion flashing
         a float m = the fmodf (Time, Slice); // this is completed scintillator progress 
        _target -> setVisible (m> Slice / 2 ? to true : false ); // this progress to be seen in half on, half hidden not to achieve the effect of flickering 
    }
