Phaser.GameObjects.Text #

Text自身会生成一个内部的隐藏画布，通过标准的Canvas fillText API把文字渲染上去。然再通过这个画布生成纹理，渲染到游戏上。

您只能显示当前已加载且可供浏览器使用的字体：因此字体必须预先加载。Phaser不会为您做这些事情，所以您需要使用第三方字体加载器，或者在您的Phaser游戏所在页面的CSS中准备好字体。

关于性能的说明：每当一个Text对象的内容发生变化时，即改变显示的文本或文本的样式，就需要重新制作Text画布，如果是在WebGL上，则需要重新上传新的纹理到GPU。如果经常使用，或者在游戏中使用大量的Text对象，这可能是一个昂贵的操作。如果你遇到性能问题，你最好使用Bitmap Text，因为它受益于批处理并避免昂贵的Canvas API调用。
