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

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. TintTo TintBy

The method of passing rgb create three values, To, and By are relative and absolute difference update

6. 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 
    }
