setContentSize不工作

我是cocos2dx的新手，我想把另一个类的层添加到我的主Splashscreen类中，但setContentSize使用设备宽度和高度。

我想设置图层大小和我的精灵大小。

查看我的代码

小工具.cpp

#include "Gadget.h"
#include "math.h"
int nCount = 100;
static CCPoint Circle [100]; // vertex array
Gadget* Gadget::create(int type)
{
    Gadget *pRet = new Gadget();
    if (pRet && pRet->init(type))
    {
        pRet->autorelease();
        return pRet;
    }
    else
    {
        delete pRet;
        pRet = NULL;
        return NULL;
    }
}
bool Gadget::init(int type)
{
    if(!LayerColor::init())
    {
        return false;
    }
    this->setContentSize(CCSize::ZERO);
    this->initWithColor(Color4B(255,255,255,255));
    CCLog("Before Calling");
    addGadget(type);
    return true;
}
Gadget::Gadget() {
    // TODO Auto-generated constructor stub
}
Gadget::~Gadget() {
    // TODO Auto-generated destructor stub
}
void Gadget::addGadget(int type)
{
    const char* image   =       "gadget_2.png";
    if(type==2)
    {
        image           =       "gadget_1.png";
    }
    //this->initWithFile(image);
    CCLog("After Calling");
    CCSprite *spr = CCSprite::create(image);
    setGadgetPos(this->getContentSize().width/2,0.0);
    this->drawCircle(100,100,100);
}
void Gadget::setGadgetPos(float x, float y)
{
//  this->ignoreAnchorPointForPosition(true);
    this->setPosition(x,y);
}
void Gadget::gadgetAnimStart(int type)
{
    if(type==1)
    {
        this->setAnchorPoint(ccp(0,3));
        auto rotate = RotateBy::create(3,360);
        this->runAction(CCRepeatForever::create(rotate));
    }
}
void Gadget::gadgetAnimStop()
{
    this->stopAllActions();
}
void Gadget::drawCircle(float X, float Y,float rad)
{
    DrawNode *drawnode = DrawNode::create();
    for ( int i = 0 ; i <100; i ++)
    {
        float rads = i * M_1_PI; // radians
        Circle [i] .x = rad * cosf (rads); //vertex x
        Circle [i] .y = rad * sinf (rads); //vertex y
    }
    drawnode->setPosition(Director::sharedDirector()->getVisibleSize().width/2,Director::sharedDirector()->getVisibleSize().height/2);
    drawnode->drawPolygon(Circle,100,Color4F(0,0,0,0),1,Color4F(1,122,153,1));
    this->addChild(drawnode);
}

我必须在Splashscreen.cpp 上使用Gadget.co类

#include "Splashscreen.h"
#include "HelloWorldScene.h"
#include "CCHelper.h"
#include "Gadget.h"
#include "UserDefaultStorage.h"
#include "VisibleRect.h"
#include "math.h"
#include "Sound.h"
#include "Text_En.h"
USING_NS_CC;
Scene* Splashscreen::createScene()
{
    Scene *s = Scene::create();
    LayerColor *lc = Splashscreen::create();
    s->addChild(lc);
    return s;
}
Splashscreen::Splashscreen() {
    // TODO Auto-generated constructor stub
}
Splashscreen::~Splashscreen() {
    // TODO Auto-generated destructor stub
}
bool Splashscreen::init()
{
    if(!LayerColor::create())
    {
        return false;
    }

    this->initWithColor(ccc4(0,0,0,255));
    this->setContentSize(CCSizeZero);
    Gadget *g = Gadget::create(GREEN_GADGET);
    g->setPosition(ccp(-100,-100));
    this->addChild(g);
 return true;
}

当我使用"this->setContentSize（CCSizeZero）；"代码但视图中没有更改时。它从位置-100，-100 生成全屏层

请给我一些解决方案，为什么setContentSize不起作用。

提前感谢Rishabh Shah

初始化后，setContentSize将设置大小，但不会进行任何可见的更改，在初始化时提供宽度和高度会更好。

类似：

 this->initWithColor(ccc4(0,0,0,255), width, height);

if(!LayerColor::create())
{
    return false;
}

应该是

if(!LayerColor::init())
{
    return false;
}
