Creating a SpriteBatchNode subclass for sprite animation

SpriteBatchNode is one of the most usefull class of cocos2d-x-3.2

Now here I am creating a subclass which is extend from SpriteBatchNode

You .h file

#ifndef _ANIMALANIMATION_H_

#define _ANIMALANIMATION_H_

#include "cocos2d.h"

class animalAnimation : public cocos2d::SpriteBatchNode

{

    public:

             

        animalAnimation();

        ~animalAnimation();

        static animalAnimation* create(std::string spriteReference,std::string plistname,std::string firstframe,int frames);

        void initOptions(std::string plistname,std::string firstframe,int frames);

             

};

#endif //

Now .cpp file

#include "animalAnimation.h"

using namespace cocos2d;

 animalAnimation::animalAnimation() {}

 animalAnimation::~animalAnimation() {}

 animalAnimation* batch;

 animalAnimation*  animalAnimation:: create(std::string spriteReference,std::string plistname,std::string firstframe,int frames)

{

     batch = new animalAnimation();

        if (batch && batch->initWithFile(spriteReference,1))

    {

        batch->autorelease();

              batch->initOptions(plistname,firstframe,frames);

           return batch;

    }

   CC_SAFE_DELETE(batch);

    return NULL;

}

void  animalAnimation::initOptions(std::string plistname,std::string firstframe,int frames)

{

       std::string startframe=firstframe;

      

       std::string beginFrame=startframe.append("0001.png");

       std::string keyframes=firstframe.append("%04d.png");

       SpriteFrameCache* cache = SpriteFrameCache::getInstance();

    cache->addSpriteFramesWithFile(plistname);

        auto bearSprite = Sprite::createWithSpriteFrameName(startframe);

    batch->addChild(bearSprite);

        auto body = PhysicsBody::createCircle(bearSprite->getContentSize().width /2);

       body->setRotationEnable(false);

       body->setRotationEnable(true);

       body->setAngularDamping(0.5f);

       bearSprite->setPhysicsBody(body);

      

       Vector<SpriteFrame*> animFrames(17);

      

       char str[100] = {0};

      

        for(int i = 1; i <= frames; i++)

    {

              sprintf(str, keyframes.c_str(), i);

        SpriteFrame* frame = cache->getSpriteFrameByName(str);

              animFrames.pushBack(frame);

    }

         Animation* animation = Animation::createWithSpriteFrames(animFrames, 0.3f);

      

         bearSprite->runAction( CCSpeed::create(RepeatForever::create( Animate::create(animation) ), 13.5f)); 

}

//Importing and working with animalAnimation class

// create("nameofursprite.png"," nameofursprite.t.plist","staringframe",numberofframes)

animalAnimation

*animal=animalAnimation::create("newspritesheet.png","newspritesheet.plist","giraffe",11);

//where p is Vec2(x,y ) position

               animal->setPosition(p);

               addChild(animal);
