IOS_31_cocos2d_Progress progress bar and cocos2d progress bar
Finally:
Progress bar node [CCProgressNode],The constructor depends on a Sprite.IsCCProgressNode] AddCCActionProgressFromToAction
You can also change the CCProgressNode in the update method.The percentage attribute of to achieve the progress bar effect.
CCProgressNode]Basic attributes:
CCProgressNode] Constructor:

There are only two types:Radar and bar

What is the role of the progress bar of the cocos2d-x, what is the need to load the progress bar, there are specific examples,

The progress bar is used in many places. First, you can view the game progress and the unit's blood volume and magic volume. If this attribute can be quantified, you can use the progress bar to display the progress, progress bars are often used in game development.
Of course, you can download network resources, loading progress of program initialization, and so on.
There are many examples of initialization Methods online,
CCProgressTo * p1 = CCProgressTo: actionWithDuration (2,80 );
CCProgressTimer * pt = CCProgressTimer: progressWithFile ("radial.png ");
Pt-> setType (kCCProgressTimerTypeRadialCW );
AddChild (pt );
Pt-> setPosition (ccp (size. width/2, size. height/2 ));
Pt-> runAction (CCRepeatForever: actionWithAction (p1 ));

How to Implement progress bar using C language

CreateWindow (PROGRESS_CLASS, NULL, WS_VISIBLE | WS_CHILD | PBS_SMOOTH, 20,370,370, 30, hwnd, (HMENU) 200, (LPCREATESTRUCT) lParam)-> hInstance, NULL );
