类名称：Stage
方法名：hit

Stage.hit介绍

[英]Returns the Actor at the specified location in stage coordinates. Hit testing is performed in the order the actors were inserted into the stage, last inserted actors being tested first. To get stage coordinates from screen coordinates, use #screenToStageCoordinates(Vector2).
[中]返回舞台坐标中指定位置的演员。命中测试按照演员被插入舞台的顺序进行，最后一个插入的演员首先被测试。要从屏幕坐标中获取舞台坐标，请使用#屏幕到舞台坐标（矢量2）。
