本文整理了Java中com.badlogic.gdx.scenes.scene2d.Actor.draw()方法的一些代码示例，展示了Actor.draw()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Actor.draw()方法的具体详情如下：
包路径：com.badlogic.gdx.scenes.scene2d.Actor
类名称：Actor
方法名：draw

Actor.draw介绍

[英]Draws the actor. The batch is configured to draw in the parent's coordinate system. Batch#draw(com.badlogic.gdx.graphics.g2d.TextureRegion,float,float,float,float,float,float,float,float,float) is convenient to draw a rotated and scaled TextureRegion. Batch#begin() has already been called on the batch. If Batch#end() is called to draw without the batch then Batch#begin() must be called before the method returns.

The default implementation does nothing.
[中]吸引演员。批次配置为在父对象的坐标系中绘制。Batch#draw（com.badlogic.gdx.graphics.g2d.TextureRegion，float，float，float，float，float，float，float，float）可以方便地绘制旋转和缩放的TextureRegion。批处理#begin（）已在批处理上调用。如果调用Batch#end（）来绘制而不使用Batch，则必须在方法返回之前调用Batch#begin（）。
默认实现不执行任何操作。
