Button 的create函数可以传入三个资源图片参数，第一个是初始的状况，第二个是点击时候的图片（如果为NULL，默认为变大），第三个是设置为不可用（Enable设置为false）的图片（如果为NULL，默认为显示为灰色）

Button* button = Button::create("green_block.png");    button->setName("button");    button->setTitleText("1");    button->setPosition(Point(100, 100));    this->addChild(button);    button->addClickEventListener(CC_CALLBACK_1(HelloWorld::Click,this));

void HelloWorld::Click(cocos2d::Ref * ref){    //Button* button = static_cast<Button *>(ref);    //button->setEnabled(false);    auto bird = static_cast<Sprite*>(getChildByName("bird"));    bird->stopAllActions();    int x = random(-50, 50);    int y = random(-50, 50);    MoveBy* moveby = MoveBy::create(1.2, Vec2(x, y));    //int z = random(0, 3);    if (x >= 0 && y < 0) {        z = 0;    }    if (x < 0 && y < 0) {        z = 1;    }    if (x >= 0 && y >= 0) {        z = 2;    }    if (x < 0 && y >= 0) {        z = 3;    }    Animation* animation = static_cast<Animation*>(anim_array->getObjectAtIndex(z));    Animate *animate = Animate::create(animation);    Repeat* repeat = Repeat::create(animate,3);    Spawn* spw = Spawn::create(moveby, repeat, NULL);    CallFunc* call = CallFunc::create(this, callfunc_selector(HelloWorld::callback));    Sequence* sq = Sequence::create(spw, call, NULL);    bird->runAction(sq);}
