cocos2dx学习日记二：Label的创建方法和属性

	auto label = Label::create("helloworld","Arial",50);//创建label

	label->setPosition(visibleSize.width / 2,visibleSize.height / 2);

	this->addChild(label);

	auto label2 = Label::createWithTTF("hello cocos","fonts/Marker Felt.ttf",50);

	label2->setPosition(visibleSize.width / 2,visibleSize.height / 4);

	this->addChild(label2);

	auto label3 = Label::createWithBMFont("markerFelt.fnt","hello everybody");

	label3->setPosition(visibleSize.width / 4,visibleSize.height / 2);

	this->addChild(label3);

	auto label4 = Label::createWithSystemFont("systemtest","arial",24);

	label4->setPosition(visibleSize.width / 4,visibleSize.height / 4);

	this->addChild(label4);

	auto label5 = Label::createWithCharMap("tuffy_bold_italic-charmap.plist");

	label5->setString("charmaptest");

	label5->setPosition(visibleSize.width / 2,visibleSize.height*0.75);

	this->addChild(label5);

label的创建和精灵一样，调用静态方法进行创建，然后设置位置，并添加到层中。

	label->setAnchorPoint(Point(0,0));//设置锚点

	label2->setColor(Color3B::GREEN);//设置颜色

	label3->setRotation(var);//设置旋转角度

	label4->setScale(2.0f);//放大缩小

	label5->setString("testcharmap");//修改内容

修改label属性，生成如下图：

        label->setAlignment(TextHAlignment::CENTER);//对齐方法

	label2->enableOutline(Color4B::GREEN,3);//发光

	label3->setAdditionalKerning(20);//设置字间距

	label4->enableShadow();//设置阴影

	label5->setLineHeight(10);//设置行高
