序言

回顾cocos2dx,之前在mac+Xcode平台学习了一遍cocos2dx,一年时间不接触cocos了,一直在搞Unity3d,现在还是就之前所学温故温故,但不再用Xcode来写,用常用的Windows+VS2012做为开发环境来回顾cocos2dx。从CCSprite精灵类开始回顾起。

CCSprite多种创建方式


创建CCSprite精灵类有好多中方式,好多构造函数,这里列举集中创建形式,包括要显示某个部分和缓存帧,2D贴图创建和普通创建等。


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

	CCSize size = CCDirector::sharedDirector()->getWinSize();
	//加载精灵
	//方式一
	CCSprite *sprite = CCSprite::create("icon.png");  //123px*123px的图片
	sprite->setPosition(ccp(size.width*0.2,size.height*0.7));
	this->addChild(sprite);

	//方式二
	//设置显示区域
	CCSprite *sprite1 = CCSprite::create("icon.png",CCRect(0,0,60,60)); //只取60px*60px的图片
	sprite1->setPosition(ccp(size.width*0.5,size.height*0.7));
	this->addChild(sprite1);

	//方式三
	//创建2d文理来创建精灵
	CCTexture2D *texture = CCTextureCache::sharedTextureCache()->addImage("icon.png");
	CCSprite *sprite2 = CCSprite::createWithTexture(texture);
	sprite2->setPosition(ccp(size.width*0.8,size.height*0.7));
	this->addChild(sprite2);

	//方式四
	//还是设置显示区域
	CCSprite *sprite3 = CCSprite::createWithTexture(texture,CCRect(61.5,61.5,61.5,61.5));
	sprite3->setPosition(ccp(size.width*0.2,size.height*0.3));
	this->addChild(sprite3);

        //方式五
	//缓存帧
	CCSpriteFrame *frame = CCSpriteFrame::create("icon.png",CCRect(0,0,61.5,61.5));
	CCSprite *sprite4 = CCSprite::createWithSpriteFrame(frame);
	sprite4->setPosition(ccp(size.width*0.5,size.height*0.3));
	this->addChild(sprite4);

	//方式六
	/*CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("img.plist");
	CCSprite *sprite5 = CCSprite::createWithSpriteFrameName("icon.png");
	sprite5->setPosition(ccp(size.width*0.7,size.height*0.3));
	this->addChild(sprite5);*/

CCSprite缩小和放大


CCSprite->SetScale():参数介于0~无穷,就可实现精灵的放大和缩小功能。



//精灵的缩小和放大
	CCSprite *spriteS= CCSprite::create("icon.png");  //123px*123px的图片
	spriteS->setPosition(ccp(size.width*0.2,size.height*0.5));
	spriteS->setScale(0.5f);
	this->addChild(spriteS);

	CCSprite *spriteM = CCSprite::create("icon.png");  //123px*123px的图片
	spriteM->setPosition(ccp(size.width*0.7,size.height*0.5));
	spriteM->setScale(1.5f);
	this->addChild(spriteM);


[windows+cocos2dx]CCSprite精灵类_ico_02





SetScaleX,SetScaleY是只针对X、Y方向的缩放


例如:sprite->setScaleX(1.5f);              sprite2->setScaleY(1.5f);

CCSprite旋转

CCSprite->setRotation();参数是度数,正数代表顺时针旋转多少度,负数代表逆时针旋转多少度。

//精灵的旋转
	CCSprite *spriteL= CCSprite::create("icon.png");  //123px*123px的图片
	spriteL->setPosition(ccp(size.width*0.3,size.height*0.5));
	spriteL->setRotation(30.0f);
	this->addChild(spriteL);

	CCSprite *spriteR= CCSprite::create("icon.png");  //123px*123px的图片
	spriteR->setPosition(ccp(size.width*0.8,size.height*0.5));
	spriteR->setRotation(-30.0f);
	this->addChild(spriteR);

CCSprite倾斜


CCSprite->setSkewY();参数是度数,正数代表顺时针倾斜多少度,负数代表逆时针倾斜多少度。


//精灵的倾斜
CCSprite *spriteL= CCSprite::create("icon.png");  //123px*123px的图片
spriteL->setPosition(ccp(size.width*0.3,size.height*0.5));
spriteL->setSkewY(30.0f);
this->addChild(spriteL);

CCSprite *spriteR= CCSprite::create("icon.png");  //123px*123px的图片
spriteR->setPosition(ccp(size.width*0.8,size.height*0.5));
spriteR->setSkewY(-30.0f);
this->addChild(spriteR);

CCSprite设置不可见和变色


//精灵可见和变色
//设置不可见
CCSprite *spriteL= CCSprite::create("icon.png");  //123px*123px的图片
spriteL->setPosition(ccp(size.width*0.3,size.height*0.5));
spriteL->setVisible(false);
this->addChild(spriteL);
//变成红色
CCSprite *spriteR= CCSprite::create("icon.png");  //123px*123px的图片
spriteR->setPosition(ccp(size.width*0.8,size.height*0.5));
spriteR->setColor(ccc3(255,0,0));
this->addChild(spriteR);

CCSprite设置透明度

//设置透明度
CCSprite *spriteL= CCSprite::create("icon.png");  //123px*123px的图片
spriteL->setPosition(ccp(size.width*0.3,size.height*0.5));
spriteL->setOpacity(100);//0~255
this->addChild(spriteL);

CCSprite *spriteR= CCSprite::create("icon.png");  //123px*123px的图片
spriteR->setPosition(ccp(size.width*0.7,size.height*0.5));
spriteR->setOpacity(230);//0~255
this->addChild(spriteR);

CCSprite替换图片


//替换图片
CCSprite *spriteR= CCSprite::create("icon.png");  //123px*123px的图片
spriteR->setPosition(ccp(size.width*0.7,size.height*0.5));
spriteR->setOpacity(230);//0~255
this->addChild(spriteR);
spriteR->setTexture(CCTextureCache::sharedTextureCache()->addImage("CloseNormal.png"));
