inheriting from CCSprite to create animation

cocos2d-x C++
#1

Hello i try to create simple sprite that will hold frame animation but i must doing something wrong here
i followed the tutorial from here [[http://www.cocos2d-x.org/projects/cocos2d-x/wiki/Animations]]
the first part . i didn’t do the secound part becouse i didint found any free tool that export to plist but this is another problem .
any way here is my code i invoke it from the bool HelloWorld::init()
but i don’t see any thing in the screen

bool HelloWorld::init()
{
...
...
...
do 
    {

m_AngelSprite =  new AngelSprite();
        CC_BREAK_IF(! m_AngelSprite);
        m_AngelSprite->setPosition(ccp(m_AngelSprite->getContentSize().width/2,iHeight/2));
        this->addChild(m_AngelSprite);
  bRet = true;
    } while (0);
}



#ifndef __ANGELSPRITE_H__
#define __ANGELSPRITE_H__

#include "cocos2d.h"

class AngelSprite : public cocos2d::CCSprite
{
    public :
        virtual void draw();
        AngelSprite();
        //virtual ~AngelSprite(){};
        //virtual void draw(void);
        void runAnimation();


    private:
        cocos2d::CCAnimation *animation; 
        cocos2d::CCAnimate *action;
        void playImageAnim();
        void loadImgs();


};



#endif

#include "AngelSprite.h"


AngelSprite::AngelSprite()
{
    animation = cocos2d::CCAnimation::create();
    loadImgs();
    playImageAnim();
    action =  cocos2d::CCAnimate::create(animation);
}


void AngelSprite::draw()
{
    //CCSprite::draw();
}


void AngelSprite::loadImgs()
{
    for(int i=1;i<=2;i++)
    {
        char szImageFileName[128] = {0};
        sprintf(szImageFileName, "angel_%d.png",i);
        animation->addSpriteFrameWithFileName(szImageFileName);  
    }
}

void AngelSprite::playImageAnim()
{
    animation->setDelayPerUnit(0.8f / 2.0f); // This animation contains 14 frames, will continuous 2.8 seconds.
    animation->setRestoreOriginalFrame(true); // Return to the 1st frame after the 14th frame is played. 
}

void AngelSprite::runAnimation()
{
    this->runAction(action);  // run action on sprite object
}

What OS are you building on? TexturePacker is free and works fine.

Anyway, you overridden the draw* method which does the rendering.
What I usually do when subclassing, is to subclass CCNode and just have a CCSprite member on it.
<pre>
class Angel : public cocos2d::CCNode {
private:
cocos2d::CCSprite m_Sprite;

public:
cocos2d::CCSprite * getSprite();
}

I would then use \*Angel::getSprite()\* if I want to control the sprite outside of the class.

If you want to create a sprite animation where you provide the frames manually, then subclass from CCSprite and set the displayFrame at each key frame update.

That’s all there is to it.

`Jacob Anderson
can you please give me short code spinet to understand what you mean ?

`Lance Gray
thanks for the replay , what is better do you think in such cases , when you what to build custom sprite ?
to subclass node or sprite

#5

@Lance Gray
about TexturePacker i don’t understand here something basic
the txt file it creates its content dosnt look like the xml i see in .plist files for example in animations/animations-2.plist

I’ve always used to inherit CCNode and it works. I sticked to it ever since.

Did you select cocos2d as output? Can you post screenshot?

You are not getting any image on screen because you havent initialized the base class. Call CCSprite::initWith…() method.
