handling multiple sprite animation in cocos2dx3.2

many times in gaming world we need to handle multiple animation for e.g. when hero is running we have to call running sprite or frames when hero is jumping we need to call jumping frame here is my solution for that

    {

    }

    playanimation(moveToNext, true,24.0f,"");

    

}

//this class batch all animation in a single class and play them when they required

now include this class on your game using

#include "spriteSheet.h"

add a spriteSheet variable

spriteSheet *myhero;

     // add more code 

  //where  heroRunning1.png is the first frame of animation

    myhero= spriteSheet::create("hero.png", "hero.plist", "heroRunning1.png");

    myhero->setPosition(Vec2(600,50));

    myhero->setName("Hero");

    myhero->addAnimation("heroRunning","run", 15);//add first animation 

    myhero->addAnimation("heroJumpDown","roll", 20);//add 2 animation 

    myhero->addAnimation("heroJumpUp","jump", 2);//add 3 animation 

  

//play a animation in loop

    myhero->playanimation("run",true,24,"");

//play a animation at single time 

  myhero->playanimation("jump",false,3,"run");

    addChild(myhero);
