cocos2dx创建sprite的多种方法

Posted 2020-06-13

方法一

最常用，也是最简单的一种方法

CCSprite *bg=CCSprite::create("sprite/background.jpg",CCRectMake(0,0,480,320));
    bg->setAnchorPoint(ccp(0,0));
    bg->setPosition(CCPointZero);
    addChild(bg);

方法二

利用纹理创建sprite

    CCImage *image=new CCImage();
    image->initWithImageFile("sprite/plant.png");
    CCTexture2D *texture=new CCTexture2D();
    texture->autorelease();
    texture->initWithImage(image);
    CCSprite *plant=CCSprite::createWithTexture(texture);
    plant->setPosition(ccp(100,winSize.height/2));
    addChild(plant);

方法三

将图片加载到缓存中

    CCTexture2D * texture2=CCTextureCache::sharedTextureCache()->addImage("sprite/bullet.png");
    CCSprite *bullet=CCSprite::createWithTexture(texture2);
    bullet->setPosition(ccp(200,winSize.height/2+10));
    addChild(bullet);

方法四

CCSpriteFrame方法

    CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("sprite/zombie.plist");
    //CCSpriteFrame *sf=CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("z_1_attack_05.png");
    //CCSprite * zombie=CCSprite::createWithSpriteFrame(sf);
    CCSprite *zombie=CCSprite::createWithSpriteFrameName("z_1_attack_06.png");
    zombie->setPosition(ccp(400,winSize.height/2-50));
    addChild(zombie);

    CCJumpBy *by=CCJumpBy::create(2,ccp(0,0),40,3);

    zombie->runAction(CCRepeatForever::create(by));

也可以直接使用spriteFrame加载sprite

    CCSpriteFrame * frame=CCSpriteFrame::create("sprite/p_1_01.png",CCRectMake(0,0,80,80));
    CCSprite *sun=CCSprite::createWithSpriteFrame(frame);
    sun->setPosition(ccp(400,winSize.height/2+100));
    addChild(sun);
