cocos2d 制作5星评分效果

做的是一个评分的展示，不涉及评分的操作

cocos2dx 3.0+

效果如下，分别为8.6分，5分和10分

for (int i = 0; i < (int)score / 2; i++)
	{
		auto starImg = Sprite::create("appstore/applist/star_full.png");
		starImg->setAnchorPoint(Point::ANCHOR_TOP_LEFT);
		starImg->setPosition(26 + i * 35,48);
		_detailHolder->addChild(starImg,POSTER_LAYER);
	}
	float percent = score/2 - (int)score/2;
	if ( percent != 0)
	{
		auto starImg = Sprite::create("appstore/applist/star_empty.png");
		starImg->setAnchorPoint(Point::ANCHOR_TOP_LEFT);
		starImg->setPosition(26 + (int)score / 2 * 35 + starImg->getContentSize().width * percent,48);
		starImg->setTextureRect(Rect(starImg->getContentSize().width * percent,starImg->getContentSize().width - starImg->getContentSize().width * percent,starImg->getContentSize().height));
		_detailHolder->addChild(starImg,POSTER_LAYER);

		auto starImg2 = Sprite::create("appstore/applist/star_full.png");
		starImg2->setAnchorPoint(Point::ANCHOR_TOP_LEFT);
		starImg2->setPosition(26 + (int)score / 2 * 35,48);
		starImg2->setTextureRect(Rect(0,starImg2->getContentSize().width * percent,starImg2->getContentSize().height));
		_detailHolder->addChild(starImg2,POSTER_LAYER);
	}
